Dear customer,
Your VACUUBRAND diaphragm pumps are designed to provide you with
many years of trouble-free service with optimal performance. Our many
years of practical experience allow us to provide a wealth of application
and safety information. Please read these instructions for use before the
initial operation of your pump.
VACUUBRAND diaphragm pumps combine our many years of experience in design, construction and practical operation, with the latest developments in material and manufacturing technology.
Our quality maxim is the ?zero defect? principle:
Every diaphragm pump, before leaving our factory, is tested intensively,
including an endurance run of 14 hours. Any faults, even those which occur rarely, are identified and can be eliminated immediately.
After completion of the endurance run, every pump is tested, and must
achieve specifications before shipment.
We are committed to providing our customers only pumps that meet this
high quality standard.
While our pumps cannot eliminate all of your work, we design, manufacture and test them to ensure that they will be an effective and trouble-free
tool to assist you in that work.
Yours,
VACUUBRAND GMBH + CO KG

page 14 of 106
?Comply with all notes on correct vacuum and electrical connections; see section ?Use and operation?, pg.
32.
+Do not use the pump to generate pressure.
+The pumps are designed for ambient temperatures
during operation between +50°F and +104°F (+10°C
and +40°C). Periodically check maximum temperatures if installing the pump in a cabinet or a housing.
Make sure ventilation is adequate to maintain recommended operating temperature. Install an external automatic ventilation system if necessary. If pumping hot
process gases, make sure that the maximum permitted
gas inlet temperature is not exceeded. The maximum
permitted gas inlet temperature depends on several
parameters like inlet pressure and ambient temperature (see ?Technical data?, pg. 25).
+Particles and dust must not enter the pump.
+Do not pump liquids.
? Ensure that the pump is chemically resistant to the
pumped substances prior to operation.
NOTICE
Use the equipment only as intended, that is, for generation, measurement, and control of vacuum in vessels designed for that purpose. Any other use will automatically
invalidate all warranty and liability claims.
Remain aware of safety and risks.
Setting up and installing the equipment
? Equipment must be connected only to a suitable electrical supply and a suitable ground point. As such,
the plug must be plugged into an outlet that is properly
grounded. Failure to connect the motor to ground may
result in deadly electrical shock.
page 15 of 106
The supply cable may be fitted with a molded European IEC plug or a plug suitable for your local electrical
supply. The cable contains wires color coded as follows: green or green and yellow: ground; blue or white:
neutral; brown or black: hot.
?Due to the high compression ratio, the pump may generate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust pipeline or exhaust valve) at the outlet.
?Do not permit any uncontrolled pressurizing. Make
sure that the exhaust pipeline cannot become blocked.
If there is an exhaust isolation valve, make sure that you
cannot operate the equipment with the valve closed to
avoid a risk of bursting!
?Maximum permissible pressure at the pressure transducer: 21.8 psi (1.5 bar) absolute.
?Keep the electrical power cord away from heated surfaces.
? Provide a firm, level platform for the equipment. Check
that the system which you are going to evacuate is
mechanically stable. Check that all fittings are secure.
Ensure a stable position of the pump without any mechanical contact other than the pump feet.
? Comply with maximum permissible pressures at inlet and outlet and with maximum permissible pressure differences between inlet and outlet. See section
?Technical data?, pg. 25. Do not operate the pump
with overpressure at the inlet.
? Comply with maximum permissible pressures at the
pressure transducer. See section ?Technical data?, pg.
25.
? Avoid overpressure of more than 17.5 psi absolute (1.2
bar absolute) in the event that inert gas is connected to
the pump, or to a venting valve.
page 16 of 106
? Note: Flexible elements will shrink when evacuated.
? Connect hoses gas tight at inlet and outlet of the pump.
? Connect hoses gas tight at the pressure transducer.
? Ensure that no foreign objects can be drawn into the
pump.
? Check the power source and the pump?s rating plate
to be sure that the power source and the equipment
match in voltage, phase, and frequency.
NOTICE
Make sure ventilation is adequate to maintain recommended operating temperature. Keep a minimum distance of
2 in (5 cm) between the cooling fan and surrounding items
(e.g., housing, walls, etc.), or else install an external automatic ventilation system. Check fan regularly for dust/dirt.
Clean fan guard grill if necessary to avoid a reduction of
ventilation.
MV 10 VARIO-B: Do not place the pump on soft surfaces
(e.g., rubber foam) during operation. This may reduce or
block the fans? air supply.
Position the pressure transducer and its vacuum line in
such a way that condensate cannot flow towards the pressure transducer.
Use only hoses at the inlet and outlet of the pump with
an inner diameter at least as large as the diameter of the
pump?s tubing (to avoid overpressure at the outlet, and
reduction of pumping speed at the inlet).
Allow the equipment to equilibrate to ambient temperature
if you bring it from cold environment into a room prior to
operation. Notice if there is water condensation on cold
surfaces.
Comply with all applicable and relevant safety requirements (regulations and guidelines). Implement the required actions and adopt suitable safety measures.
page 17 of 106
Ambient conditions
?Do not reach for this product if it has fallen into liquid.
There is a risk of deadly electrical shock. Unplug the
system immediately.
+Do not use this product in an area where it can fall or
be pulled into water or other liquids.
? Adopt suitable measures in case of differences from
recommended conditions, e.g., using the equipment
outdoors, installation in higher altitudes, conductive
pollution or external condensation on the pump.
? Do not operate this product near flames.
NOTICE
To the best of our knowledge the equipment is in compliance with the requirements of the applicable EC-directives and harmonized standards (see ?Declaration of Conformity?) with regard to design, type and model. Directive
EN 61010-1 gives in detail the conditions under which the
equipment can be operated safely (see also IP degree of
protection, ?Technical data?, pg. 25).
Operating conditions
?These pumps are not approved for operation in potentially explosive atmospheres. Do not operate the
pumps in potentially explosive atmospheres.
?Pumps without the ? ? mark on the rating plate are
not approved for the pumping of potentially explosive atmospheres. Do not pump potentially explosive atmospheres with those pumps
?Pumps bearing the ? ? mark on their rating plates
are approved for the pumping of potentially explosive atmospheres according to their classification II 3G IIC T3 X according to ATEX, but they are
not approved for operation in potentially explosive
atmospheres(see section ?` Important information:
Equipment marking (ATEX)?, pg. 23).
page 18 of 106
?The pumps are not suitable to pump any of the substances listed below.
Do not pump:
- unstable substances
-substances which react explosively under impact
(mechanical stress) without air
- substances which react explosively when being exposed to elevated temperatures without air,
- substances subject to auto-ignition,
- substances which are inflammable without air
- explosive substances.
?The pumps are not approved for operation below
ground. Do not operate the pump below ground.
? Do not pump substances which may form deposits inside the pump. The pumps are not suitable for
pumping substances which may form deposits inside
the pump. Deposits and condensate in the pump may
lead to increased temperatures even to the point of
exceeding the maximum permitted temperatures.
? Check the inlet and outlet of the pump, if there is a
danger of forming deposits inside the pump, e.g., in
the pump chambers (the pump chamber is the part
between diaphragm and head cover. See section ?Replacing diaphragms and valves?, pg. 85). Inspect the
pump chambers regularly and clean if necessary.
? Consider interactions and chemical reactions of
the pumped media. Ensure that the materials of the
pump?s wetted parts are compatible with the pumped
substances, see section ?Technical data?, pg. 25.
When changing the substances pumped, we recommend purging the pump with air or inert gas prior to
changing the pumped media. Purging the pump will
pump out residues and it will reduce the possibility of
reactions of the pumped substances with each other
and with the pump?s materials.
page 19 of 106
Safety during operation
? Adopt suitable measures to prevent the release of dangerous, toxic, explosive, corrosive, noxious or polluting fluids, vapors and gases. To prevent any emission
of such substances from the pump outlet, install an
appropriate collecting and disposal system and take
protective action for pump and environment.
?You must take suitable precautions to prevent any formation of explosive mixtures in the pump chamber or
at the outlet of the pump. In case, e.g., of a diaphragm
failure, mechanically generated sparks, hot surfaces
or static electricity may ignite these mixtures. Use inert
gas for venting, if necessary.
?Drain appropriately or otherwise remove any potentially explosive mixtures at the outlet of the pump, or
dilute them to non-explosive concentrations.
?Never operate this pump if it has a damaged cord or
plug.
+If the pump is not working properly, has been dropped
or has fallen into water, contact your pump service provider.
+Prevent any part of the human body from coming into
contact with vacuum.
+Make sure that the exhaust pipeline cannot become
blocked.
?Attention: At pressures above approximately 795 Torr
(1060 mbar) the pressure reading becomes incorrect
due to saturation of the pressure transducer. The display flashes. Release pressure immediately! Risk of
bursting!
+Comply with applicable regulations when disposing of
chemicals. Take into consideration that chemicals may

be contaminated. Take adequate precautions to protect people from the effects of dangerous substances
(chemicals, thermal decomposition products of fluoroelastomers). Use appropriate protective clothing and
safety goggles.
+Interruption of the pump (e.g., due to power failure),
failure of connected components or of parts of the supply, or change in parameters must not be allowed to
lead to dangerous conditions. In case of a diaphragm
failure or in case of a leak in the manifold, pumped
substances might be released into the environment or
into the pump housing or motor.
Comply with all notes regarding proper use of the
pumps, as well as operation and maintenance guidance.
+The residual leak rate of the equipment might render
possible an exchange of gas, albeit extremely slight,
between the environment and the vacuum system.
Adopt suitable measures to prevent contamination of
the pumped substances or the environment.
? Ensure that no parts of your clothing, hair or fingers
can be caught or drawn in at the inlet of the pump.
Never insert fingers or drop any other object into the
inlet or outlet.
? You must take suitable precautions to prevent any
dangerous situation from arising if the controller starts
a NT VARIO or VARIO-B pump, switches a coolant
valve or opens a venting valve.
? Attention: If the controller is set to Autostart, the process will start immediately after a power failure without pressing any further key. It is your responsibility to
ensure that automatic start-up of the system will not
lead to any dangerous condition. Provide appropriate
safety measures. Check prior to starting the process
whether the option ?Autostart? (menu: configuration) is
enabled.
page 21 of 106
? Pay attention to the safety symbol ?hot surfaces? on
the equipment. Hot parts may cause burns if touched.
Adopt suitable measures to prevent any danger arising from hot surfaces or electric sparks. Ensure that
hot surfaces of the pump do not cause burns. Provide
a suitable contact guard if necessary.
NOTICE
Prevent the backpressure of gases and the backflow of
condensates at the outlet.
Provide appropriate protective measures to allow for the
possibility of failure and malfunction. The protective measures must also allow for the requirements of the respective application.
In case of overload, the motor is shut down by a self-hold
thermal cutout in the winding.
Note: Only manual reset is possible. Press the START/
STOP key at the controller to confirm the error message.
Switch off the pump and disconnect from the power source.
Identify and eliminate the cause of failure. Wait approx.
five minutes before restarting the pump.
Maintenance and repair
NOTICE
In order to comply with laws (occupational, health and
safety regulations, safety at work law and regulations for
environmental protection) vacuum pumps, components
and measuring instruments can only be returned when
certain procedures (see section ?Notes on return to the
factory?, pg. 100) are followed.
Take advantage of our service seminars, which put special
focus on the maintenance and repair of vacuum pumps.
For details and for the online ?Instructions for repair? manual see www.vacuubrand.com.
page 22 of 106
In normal use, the lifetime of the diaphragms and valves is
typically 15,000 operating hours. Bearings have a typical
durability of 40000 h.
?Ensure that the pump cannot be operated accidentally. Never operate the pump if covers or other
parts of the pump are disassembled.
?Switch off the pump. Disconnect the electrical
power cord and wait two minutes before starting
maintenance to allow the capacitors to discharge.
?Note: The pump may be contaminated with process
chemicals, which have been pumped during operation.
Ensure that the pump is completely decontaminated
before maintenance commences.
?Take adequate precautions to protect people from the
effects of dangerous substances if contamination has
occurred. Use appropriate protective clothing, safety
goggles and protective gloves.
+Wear parts have to be replaced regularly.
+Never operate a defective or damaged pump.
+Vent the pump before starting maintenance. Isolate the
pump and other components from the vacuum system.
Allow sufficient cooling of the pump. Drain condensate,
if applicable.
NOTICE

and
VACUUBRAND equipment bearing mark (see rating plate)
` X see manual
For equipment labelled with ?` X see manual? the following classification according to Directive 94/9/EC (ATEX) is valid: ` II 3G IIC T3 X,
Internal Atm. only, Tech. File Ref.: VAC-EX01.
The classification II 3G IIC T3 X according to ATEX is only valid for the inner part (wetted part, pumped gas or vapor) of the equipment. The equipment is not suitable for use in external, potentially explosive atmospheres
(environment).
The overall category of the equipment depends on the connected components. If the connected components do not comply with the classification of the VACUUBRAND equipment, the specified category of the
VACUUBRAND equipment is no longer valid.
Vacuum pumps and vacuum gauges in category 3 are intended for connection to equipment in which during normal operation explosive atmospheres caused by gases, vapors or mists normally don?t occur; or, if they
do occur, are likely to do so only infrequently and for a short period only.
Equipment in this category ensures the requisite level of protection during normal operation.
The use of gas ballast or the operation of venting valves is only permitted if thereby explosive atmospheres normally don?t occur in the interior
of the equipment or, if they do occur, are likely to do so only infrequently
and for a short period.
page 24 of 106
The pumps are marked with ?X? (according to EN 13463-1), i.e., restrictions of the operation conditions:
? The equipment is designated for a low degree of mechanical stress
and has to be installed in a way so that it cannot be damaged from
outside.
Pumping units have to be installed so that they are protected against
shocks from the outside and against glass splinters in the event of
breakage (implosion).
? The equipment is designated for an ambient and gas inlet temperature
during operation of +10 to +40°C. Never exceed these ambient and
gas inlet temperatures. If pumping / measuring gases which are not
potentially explosive, extended gas inlet temperatures are permissible.
See instructions for use, section ?Gas inlet temperatures? or ?Technical data?.
After any intervention at the equipment (e.g., repair / maintenance) the ultimate vacuum of the pump has to be checked. Only if the pump achieves
its specified ultimate vacuum is the pump?s leak rate low enough to ensure that no explosive atmospheres will occur in the interior of the equipment.
After any intervention at the vacuum sensor, the leak rate of the equipment has to be checked.

Use and operation
When switching on the controller CVC 3000 for the very first time, a menu
to select the language of the controller menu is displayed. Select the desired language (e.g., ?English?) by turning the selection knob and press
to confirm. Then select the pressure unit (?mbar?, ?Torr? or ?hPa?) in the
same way.
It is possible to access the language selection menu at any time
by switching on the controller while keeping the selection knob
pressed.
Installing a pump in a vacuum system
?If dangerous or polluting fluids could be released at
the outlet, install an appropriate system to catch and
dispose of those fluids.
+Connect a gas-tight exhaust line at the pump outlet if
necessary. Always vent exhaust gases appropriately
(e.g., into a fume hood).
+Never block the gas outlet. The exhaust line must always be free of obstructions (no back pressure) to ensure an unimpeded discharge of gas. The cross-section of the outlet tubing must be at least the size of the
pump?s exhaust connection.
?Maximum permissible pressure: 21.8 psi (1.5 bar) absolute.
?Attention: At pressures above approximately 795 Torr
(1060 mbar) the pressure reading becomes incorrect
due to saturation of the pressure transducer. The display will flash. Release pressure immediately! Risk of
bursting!
+Particles and dust must not be aspirated. If necessary,
you must install appropriate filters. You must ensure
their suitability concerning gas flow, chemical resistance and resistance to clogging prior to use.
page 33 of 106
+Make sure ventilation is adequate, especially if the pump
is installed in an enclosure, or if the ambient temperature is elevated. Provide external ventilation, if necessary.
? Reduce the transmission of vibration. Prevent mechanical load due to rigid pipelines. Insert elastic hoses or
flexible elements as couplings between the pump and
rigid pipes.
Note: Flexible elements will compress or flatten when
evacuated if not designed for use under vacuum.
? Hose connections at the pump inlet must always be
gas tight.
? A power failure may cause accidental ventilation of the
pump. If this constitutes a potential source of danger,
take appropriate safety measures.
? Check the power source and the pump?s rating plate
to be sure that the power source and the equipment
match in voltage, phase, and frequency.
NOTICE
Make sure ventilation is adequate to maintain recommended operating temperature. Keep a minimum distance of
2 in (5 cm) between the cooling fan and surrounding items
(e.g., housing, walls, etc.), or else install an external automatic ventilation system.
Use connecting hoses with large diameter and keep them
as short as possible to avoid flow losses. Locate the pump
as closely as possible to the application.
Always install outlet tubing descending from the pump or
provide other measures to avoid backflow of condensate
towards the pump.
Use a suitable valve to isolate the pump from the vacuum
application. This is to allow the pump to warm up before
pumping condensable vapors and to clean the pump after
use before it is switched off.
page 34 of 106
When assembling, ensure vacuum-tightness. After assembly, check the whole system for leaks.
Secure hose connections at the pump appropriately, e.g.,
with hose clamps, to protect against accidental detachment.
The VACUUBRAND controller CVC 3000 can only be
operated with components compatible with the VACUUBRAND VACUU?BUS system, (see ?Accessories?, pg.
80).
The vacuum controller CVC 3000 controls VACUUBRAND
diaphragm pumps NT VARIO and VARIO-B, and optional
coolant and venting valves. Connected components (e.g.,
venting valve, external pressure transducer 3000 series)
are automatically identified and configurated. Identical
components must be configurated beforehand; information upon request.
Connect the controller CVC 3000 via the VACUU?BUS cable of the NT VARIO or VARIO-B pump to the diaphragm
pump.
Do not use more than one controller within the same
VACUU?BUS system.
Several controllers in the same VACUU?BUS system
will interfere with each other and result in error messages of the connected components (pumps, valves).
VSK 3000
The VSK 3000 is equipped with a capacitive pressure
transducer with ceramic diaphragm. It measures the actual pressure independently of the gas type, and with reference to the vacuum, i.e., absolute.
Connect the VSK 3000 pressure transducer via the
VACUU?BUS cable to the CVC 3000 controller.
Attention: Do not apply off-axis forces when assembling or removing plug connections! Observe correct orientation of the plug. To connect further components use
VACUU?BUS Y-adapters and extension cables.
page 35 of 106
Connect the pressure transducer via hose or small flange
connection to the vacuum application. Do not mount the
pressure transducer directly at the pump but close to the
application. The cross-section of the tubing should be as
large as possible.
Inside a vacuum system where evaporation occurs, e.g.,
a rotary evaporator, the vacuum is not uniform. For example, a condenser can act as a pump, or the vacuum in
the connecting tubing can be higher or lower than in the
application itself. This affects the measurement results as
well as the control levels. Therefore, carefully choose the
position where to connect the pressure transducer.
Position the pressure transducer and its vacuum line in
such a way that condensate cannot flow towards the pressure transducer. Condensate and deposits will affect the
measurement results. Clean the pressure transducer, if
necessary. See section ?Cleaning the pressure transducer?, pg. 66.
Installing the hose nozzle at the VSK 3000:
Unscrew the small flange. Slip hose nozzle with clamping
ring onto the vacuum connection and fasten with union
nut.
VACUU?BUS
The CVC 3000 controller uses VACUU?BUS protocol to
read out the pressure transducer via VACUU?BUS line.
Maximum cable length inside buildings: 32yd (30m).
VACUU?BUS extension cable 2.2 yd (2 meters): order-no.
612552.
During operation
?Vent and dispose of potentially dangerous gases or
vapors at the outlet of the pump appropriately.
page 36 of 106
+Due to the high compression ratio, the pump might
generate overpressure at the outlet. Check pressure
compatibility with system components (e.g., exhaust
tubing or exhaust valve) at the outlet. Ensure that the
pump outlet is neither blocked nor restricted.
+Maximum ambient temperature: 104 °F (40 °C)
Check the maximum temperatures, if installing the
pump in a cabinet or a housing. Make sure ventilation
is adequate, especially if the ambient temperature is
elevated.
+Operation with silencer at the outlet: Operating the
pump at a high inlet pressure or pumping dusty gases for a long time may cause clogging of the silencer.
Check the silencer regularly and replace if necessary,
or install a hose nozzle (order no. 639758) with sealing
ring (order no. 639729) instead.
? If the pump is installed at an altitude of more than 6500
ft (2000 m) above mean sea level, check compatibility
with applicable safety requirements, and adopt suitable measures. There is a risk of the motor overheating due to insufficient cooling.
? Check compatibility with the maximally permitted
pressure at outlet and the maximum pressure difference between inlet and outlet ports.
NOTICE
Do not start the pump if the pressure difference between
inlet and outlet ports exceeds max. 16.0 psi (1.1 bar).
Attempts to start the pump at higher pressure difference
may cause stalling and damage of the motor.
Prevent internal condensation, transfer of liquids or dust.
The diaphragms and valves will be damaged, if liquids are
pumped in significant amounts.
Check the pump regularly for external soiling and deposits. Clean the pump if necessary to avoid an increase of
the pump?s operating temperature.
page 37 of 106
In case of overload, the motor is shut down by a self-hold
thermal circuit breaker in the winding.
Note: Only a manual reset is possible. Press the START/
STOP key at the controller to confirm the error message.
Switch off the pump and disconnect the electrical power
cord. Identify and eliminate the cause of failure. Wait approx. five minutes before restarting the pump.
Check fan regularly for dust/dirt. Clean if necessary. Avoid
overheating (e.g., due to hot process gases).
A warm up period (approximately 15 min.) is required to
ensure that the rated ultimate vacuum and pumping speed
are attained.
Shutdown & storage
The pump can be switched off under vacuum.
NOTICE
Short-term:
Has the pump been exposed to condensate?
- Allow the pump to continue to run at atmospheric pressure for a few minutes.
Has the pump been exposed to media which may damage
the pump materials or form deposits?
- Check and clean pump heads if necessary.
Has the pressure transducer been exposed to media which
may form deposits?
- Clean pressure transducer if necessary.
Long-term:
- Take measures as described above regarding shortterm shutdown.
- Separate the pump from the application.
- Close inlet and outlet ports (e.g., with transport caps).
- Store the pump under dry conditions.

Notes on selecting the function
The CVC 3000 controller can be adapted to the specific application by
choosing the appropriate function depending on the connected components and the requirements of the application.
Automatic detection of the components
When switching on the controller, the configuration of the connected components is checked automatically.
Connected components (pump NT VARIO / VARIO-B, gauge head VSK
3000, valves) are detected automatically and controlled by the CVC
3000 until the controller is switched off. Switch off/on the controller to renew the configuration.
The last mode of operation and the preselected values (e.g., for pressure, speed or time for switching off) are stored.
If the preselections are chosen appropriately, it is possible to start immediately if similar operating conditions are desired.
The controller features five functions and one configuration menu,
see section ?Menu guide?. Each of these functions involves different menu
options, which are presented automatically and reflect the connected
components. The types of components connected (e.g., valves) determine the active menu items.
Changing the function:
?Switch controller on.
?Press ?START/STOP? key to terminate control in case control is running (e.g., if ?Autostart? is activated).
?Press ?MODE? key.
?Select function with knob and press to confirm.

pump
Preselections
?Use the selection knob to select the parameters. All parameters can
be altered even while operation control is running.
? Speed: Preselection of the motor speed for pump down. The selection ?HI? effects the maximum speed and best ultimate vacuum of the
pump (with automatic speed reduction at ultimate vacuum).
The ?Speed? is adjustable in a range of 1-100% and to ?HI?.
? Minimum: The controller switches the pump off once the preset value
for ?Minimum? has been reached.
?Minimum? is adjustable in a range of 1-795 Torr (1-1060 mbar) or can
be set to ?Off?.
A preset ?Duration? (process time) has no effect if the process is
stopped due to a preset ?Minimum? before ?Duration? is reached.
? Delay: ?Delay? determines the time the coolant valve remains open
after the process has been stopped.
The ?Delay? is adjustable in a range of 1-300 minutes or can be set to
?Off? (?Off? means that the coolant valve closes immediately when the
process stops.).
?Duration: ?Duration? determines the total process time since control
start.
The process time is adjustable between 1-1440 minutes (24 h) or can
be set to ?Off?. ?Off? indicates that no endpoint for pump down is determined.
If a ?Duration? is preset, the controller switches off the pump when the
preset process time is reached, even if a preset ?Minimum? is still not
reached.

Preselections
+Use the selection knob to select the parameters. All parameters can
be altered even while operation control is running.
? Set vacuum: The ?Set vacuum? is the set point for vacuum control
with pinpoint precision for NT VARIO / VARIO-B pumps.
The ?Set vacuum? is adjustable in a range of 1-795 Torr (1-1060 mbar)
or can be set to ?Turbo?. The selection ?Turbo? leads to the optimum
backing pressure for a turbomolecular pump.
? Speed: The maximum motor speed can be preselected (to control the
pumping speed).
The ?Speed? is adjustable in a range of 1-100% or can be set to ?HI?.
The selection ?HI? (recommended) provides the optimum pumping
speed of the pump and therefore an optimum ultimate vacuum.
?Maximum: An upper pressure limit can be preselected. The pump
switches off if the pressure limit is exceeded, e.g., at the end of suctions or filtrations. The pressure limit is only active once the pressure
has gone below ?Maximum?.
The ?Maximum? is adjustable in a range of 794-1Torr (1059 - 1 mbar)
(at the least 1 Torr (mbar) higher than the ?Set vacuum?) and to ?Off?.
?Off? means that no ?Maximum? value is preset.
? Delay: ?Delay? determines the time the coolant valve remains open
after the process has been stopped.
The ?Delay? is adjustable in a range of 1-300 minutes or can be set to
?Off? (?Off? means that the coolant valve closes immediately when the
process stops.).
?Duration: ?Duration? determines the total process time since control
start.

Auto mode
?Control of a NT VARIO / VARIO-B pump in ?Auto mode?:
Automatic detection of boiling points, and automatic adjustment
of determined boiling points as process parameters change.
Preselections
?Use the selection knob to set the parameters.
? Sensitivity: The ?Sensitivity? of the control determines the control speed.
The ?Sensitivity? is adjustable to ?high?, ?normal? or ?low?.
High sensitivity leads to a reduced pump-down speed, e.g., for small
amounts of solvents or foaming processes. Use a low sensitivity for ?noncritical? processes to reduce process time. Usually setting the ?Sensitivity? to ?normal? is appropriate.
? Speed: The maximum motor speed can be preselected (to limit the
pumping speed).
The ?Speed? is adjustable in a range of 1-100% or can be set to ?HI?.
The selection ?HI? (recommended) causes an automatic limitation of
the adaptation depending on parameters determined during the process. Only in case of very sensitive processes is it advisable to reduce
the maximum speed.
? Minimum: If the vacuum value reaches ?Minimum? the process is
stopped. Use ?Minimum? for automatic process termination.
The ?Minimum? is adjustable in a range of 2-795 Torr (2 - 1060 mbar),
or can be set to ?Auto? or to ?Off?.
When selecting ?Auto? the controller switches off automatically at the
end of the process (boiling plateau). This is recommended only for
large amounts of solvents.
? Delay: ?Delay? specifies the time the coolant valve remains open after
process stop.
The ?Delay? is adjustable in a range of 1-300 minutes or can be set to
?Off? (?Off? means that the coolant valve closes immediately when the
process stops.).
page 51 of 106
?Duration: ?Duration? determines the total process time since control
start.
The ?Duration? is adjustable between 1-1440 minutes (24 h) or can

in the final program step will cause the process to run endlessly. Terminate the process by pressing the ?STOP? key .
Vacuum: Vacuum level to be attained.
Venting valve: Operating a venting valve to reach a preset vacuum
level.
?Step?: ?Step? causes pump down as fast as possible to the preset
vacuum level. As soon as the vacuum level is reached the time meter
starts running.
?Auto?: Auto = : indicates that the system will search for a boiling
point automatically, and will automatically adapt to changes in the boiling point until a preselected time interval expires.
Auto = : indicates that the system will automatically adapt to changes in the boiling point. The program step is finished when the selected
time or pressure value has been reached.
Selecting ?Auto? in combination with ?Step? in one program step is not
possible.
? Open: Choose program (Programs 0 - 9).
? Store: This command stores an edited program or the program of the

* If the pressure difference
between the vacuum for
degassing and the expected vacuum for distillation is
very small (distillation vacuum >75% of the degassing vacuum), select the
function ?Auto ? (adapting

automatically, and then
adapting the vacuum).
?
Program step 1 should be always a definite initial state, here atmospheric
pressure (ATM). To reach this state definitely, set a tickmark at ?Vent.?
and ?Step? by pressing the selection knob.
In step 2, pumping begins, attempting to reach 300 Torr/mbar as quickly
as possible (?Step?). Vacuum holds there for 10 minutes (degassing the
solvent).
In step 3, ?Auto
? causes an automatic search of a boiling point in
the pressure interval between 300 Torr/mbar/hPa (depending on preset
pressure unit) and 2 Torr/mbar/hPa, followed by automatic adaptation to
changes in the boiling point. The following step starts either (1) once the
cumulative process time reaches the set limit (1 hour/60 minutes), even
if the preset pressure (2 Torr/mbar/hPa) has not been reached, or (2) if
a vacuum of 2 Torr/mbar/hPa is reached, even if the preset time has not
been completed.
Step 4 vents to atmospheric pressure as fast as possible and switches off
the control after one minute.

Preselections
?Use the selection knob to select the parameters.
? Set vacuum (the lower switch-off value): If the pressure drops below
the ?Set vacuum?, a time-meter starts to run and the motor speed is reduced. When the pressure exceeds the ?Set vacuum? pressure again,
the time meter is reset. If the ?Set vacuum? is not reached within 100
hours, the controller signals an error.
The ?Set vacuum? is adjustable in the range of 1-795 Torr (1-1060
mbar).
? Switch on (the higher switching value): If the pressure exceeds this
pressure, pumping down starts again.
The ?Switch on? pressure is adjustable in the range of 2-795 Torr (21060 mbar) (at the least 1 Torr (mbar) higher than the ?Set vacuum?).
In the event of a sudden high-pressure spike, pumping starts again
even if the ?Switch on? pressure has not been reached (pressure increase control).
? Delay: If the vacuum is below ?Set vacuum? for longer than the ?Delay?
time, the pump is stopped. Pumping starts again in the event of a rapid
pressure increase or if the ?Switch on? level is exceeded.
The ?Delay? is adjustable in a range of 1-300 minutes or can be set to

NOTICE
The vacuum gauge head was adjusted using factory standards, which are traceable through regular calibration in
an accredited laboratory (DAkkS calibration laboratory)
to the German national pressure standard. Depending on
the process and/or accuracy requirements, check the adjustment and readjust if necessary. For readjustment, the
device has to be adjusted both at atmospheric pressure
as well as under vacuum but only if the reference pressures are known with certainty. The adjustment mode can
be activated only if the process control is inactive. Press

Instead of adjustment under vacuum to a pressure < 0.1 Torr (mbar), adjustment to a precise0...20 mbar ly known reference pressure within the range
of?0..... 15 Torr (20 mbar) is possible. Evacuate
the measurement connection of the VSK 3000
to a pressure within 0 ..... 15 Torr (0.....20 mbar).
?In ?Configuration? menu, select program ?Adjustment? at the controller.
?The reading is automatically adjusted to ?zero?.
?Use the selection knob to adjust the display to the reference pressure
at the vacuum line within the range of 0 ..... 15 Torr (0.....20 mbar).
?Press the selection knob to confirm.
Note: The accuracy of the value of the reference pressure will directly
affect the accuracy of the adjustment. If the nominal ultimate vacuum
of a diaphragm pump is used as reference vacuum, the accuracy of the
controller might be doubtful. The diaphragm pump may not achieve the
specified value (due to condensate, poor condition, failure of valves or
diaphragm, leaks).

Calibration in the factory
Control of measuring equipment
The VACUUBRAND DAkkS calibration laboratory is accredited by the
Deutsche Akkreditierungsstelle GmbH (national accreditation body of the
Federal Republic of Germany) for the measurable variable pressure in
the pressure range from 7.5*10-4 Torr to 975 Torr (10-3 mbar to 1300
mbar) in accordance with the general criteria for the operation of testing
laboratories defined in the DIN EN ISO/IEC 17025:2000 series of standards (accreditation number D-K-15154-01).
The DAkkS is signatory to the multilateral agreements of the European
cooperation for Accreditation (EA) and of the International Laboratory Accreditation Cooperation (ILAC) for the mutual recognition of calibration
certificates.
Rely on calibration in the VACUUBRAND calibration laboratory:
- To meet the requirements of the DIN ISO 9000ff and 10012 series of
standards regarding the calibration of inspection, measuring and test
equipment at specified intervals.
- To document that the vacuum gauges calibrated are traceable to national standards of the PTB (Physikalisch-Technische Bundesanstalt;

Cleaning the pressure transducer
?Attention: Never use a pointed or sharp-edged tool
to clean the pressure transducer.
?Never touch the ceramic diaphragm of the pressure transducer with hard objects.
?Fill the measurement chamber with a solvent (e.g.,
benzene) and allow sufficient cleaning time. Observe
all regulations concerning usage and disposal of solvents!
?Drain the solvent and dispose of in accordance with
regulations. Repeat cleaning if necessary.
?Rinse the measurement chamber several times with
alcohol in order to remove all solvent residues.
?Allow the pressure transducer to dry.

Interface parameters
The CVC 3000 controller is equipped with a serial interface (RS 232C,
nine-pin Sub-D-plug).
?Plug-in or remove the cable (cable RS 232C) from the interface only if
the equipment is switched off.
?The interface is not electrically isolated from the measuring circuit.
?For optimal electromagnetic compatibility assemble an interface filter
(cat. no.: 638235).
The controller is fully operable via the serial interface. Measuring results,
preselections and the status of the controller can be read at any time.
The factory-set read and write commands are completely compatible
with the VACUUBRAND CVC 2000 controller (see sections ?Read / Write
commands CVC 2000?). An extended instruction set is available using the
command ?CVC 3? (see sections ?Read / Write commands CVC 3000?).

* Pressure setting with venting is only possible in ?Vac control? function
if a venting valve is connected and configured, and vacuum control is
started. The venting valve opens automatically if the actual pressure
is at least 7.5 Torr (10 mbar) below the preset pressure. Automatic
venting becomes inactive if vacuum control is stopped (by pressing
?START/STOP? or ?VENT?), a pressure value is set using the command OUT_SP_1, or if the function is changed. Activate the command
OUT_SP_V again if necessary.

Replacing diaphragms and valves
?Please read section ?Replacing diaphragms and valves? completely before starting maintenance.
The pictures may show other versions of pumps. This does not change
the method of replacing diaphragms and valves.
?Never operate the pump if covers or other parts of
the pump are disassembled.
?Before starting maintenance, disconnect the electrical power cord. Wait two minutes after isolating the
equipment from AC power to allow the capacitors to
discharge.
? Ensure that the pump cannot be operated ?accidentally.
?Note: The pump might be contaminated with the process chemicals that have been pumped during operation. Ensure that the pump is decontaminated before
maintenance.
?Avoid the release of pollutants.
+Never operate a defective or damaged pump.
+Take adequate precautions to protect people from the
effects of dangerous substances that may have contaminated the pump and may be released upon disassembly. Ensure that the maintenance technician is
familiar with the safety procedures which relate to the
products processed by the pumping system.
Use appropriate protective clothing, safety goggles
and protective gloves.
+ Allow sufficient cooling of the pump before starting
maintenance.
+ Vent the pump and isolate it from the vacuum system before you start maintenance.
page 86 of 106
NOTICE
Ensure that maintenance is done only by suitably
trained and supervised technicians.
The valves and diaphragms are wear parts. If the rated
ultimate vacuum is no longer achieved or in case of increased noise level, the pump interior, the diaphragms
and the valves must be cleaned and the diaphragms and
valves must be checked for cracks or other damage.
All bearings are encapsulated and are filled with long-life
lubricant. Under normal operating conditions, the drive
system is maintenance free.
In demanding circumstances, it may be efficient to check
and clean the pump heads on a regular basis. In normal
use, the lifetime of the diaphragms and valves is typically
15,000 operating hours.
- Prevent internal condensation, transfer of liquids or
dust. The diaphragms and valves will be damaged if
liquid is pumped in significant amount.
- Carry out maintenance frequently if the pump is exposed to corrosive media or in case of deposits.
- Regular maintenance will improve the lifetime of the
pump and also protect both users and the environment.

Replace diaphragms and valves of the opposite side of
the pump in the same way!
Checking the ultimate vacuum
? After any intervention at the equipment (e.g., repair / maintenance)
the ultimate vacuum of the pump has to be checked. Only if the pump
achieves its specified ultimate vacuum, the pump?s leak rate is low
enough to ensure that no explosive atmospheres will occur in the interior of the equipment.
After any intervention at the vacuum sensor the leak rate of the equipment has to be checked.
If the pump does not achieve the ultimate vacuum:
- Whenever the diaphragms and valves have been replaced, a break-in
period of several hours is required before the pump achieves its ultimate vacuum.
- In case of an unusual noise, switch off pump immediately and check
clamping disc positions.
If the specified ultimate vacuum is not achieved, and if this does not
change after the break-in period:
If necessary recheck valve seats and pump chambers.
