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 18 hours. Any faults, even those which oc-
cur rarely, are identied and can be eliminated immediately.
After completion of the endurance run, every pump is tested, and must
achieve specications 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

General information
NOTICE
Remove all packing material from the packing box. Remove the product from its packing-box and retain all packaging until the equipment is inspected and tested. Remove the protective caps from the inlet and outlet ports
and retain for future use. Inspect the equipment promptly
and carefully.
If the equipment is damaged, notify the supplier and the
carrier in writing within three days. Retain all packing material for inspection. State the item number of the product
together with the order number and the supplier’s invoice
number. Failure to check and give notice of damage will
void any and all warranty claims for those deciencies.
Replace the protective caps, if the equipment is not used
immediately. Store the equipment in dry and non-corrosive
conditions (see also “Technical data”, pg. 26).
+ Do not use any damaged equipment.
• Use the mounted handle or the recessed grips when
moving the pump.
Intended use
+ Do not use the pump or any system parts on humans
or animals.
+ Prevent any part of the human body from coming into
contact with vacuum.
+ Ensure that the individual components are only con-
nected, combined and operated according to their design and as indicated in the instructions for use.
+ Comply with all notes on correct vacuum and electrical
connections; see section “Use and operation”, pg. 38.
+ 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
Page 14
page 14 of 129
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. 26).
+ Do not aspirate particles and dust.
+ Do not pump liquids.
NOTICE
• Ensure that the pump is chemically resistant to the
pumped substances prior to operation.
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 elec-
trical 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.
The supply cable may be tted with a molded Euro-
pean 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 gen-
erate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust pipe-
Page 15
page 15 of 129
line 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 trans-
ducer: 21.8 psi (1.5 bar) absolute.
+ Always provide a free and pressureless exhaust outlet
to avoid damage to pump valves and risk of bursting of
condenser glassware.
+ Check the overpressure safety relief device at the ex-
haust waste vapor condenser at appropriate intervals.
+ Keep the electrical power cord away from heated sur-
faces.
• Provide a rm, level platform for the equipment. Check
that the system which you are going to evacuate is
mechanically stable. Check that all ttings are secure.
Ensure a stable position of the pump without any mechanical contact other than the pump feet.
• Comply with maximum permissible pressures at in-
let and outlet and with maximum permissible pres-
sure differences between inlet and outlet. See section
“Technical data”, pg. 26. Do not operate the pump
with overpressure at the inlet.
• Comply with maximum permissible pressures at the
pressure transducer. See section “Technical data”, pg.
26.
• Avoid overpressure of more than 17.5 psi absolute (1.2
bar absolute) in the event that inert gas is connected to
the pump, to the gas ballast or to a venting valve.
• 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.
Page 16
page 16 of 129
• 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.
• Ensure that the coolant outlet pipe is always free and
that it cannot get blocked. If installing an optional coolant valve, it must always be in the supply line of the
exhaust waste vapor condenser.
NOTICE
Keep a minimum distance of 8 in (20 cm) between the
cooling fan and surrounding items (e.g., housing, walls,
etc.). Check fan regularly for dust/dirt. Clean fan guard
grill if necessary to avoid a reduction of ventilation.
PC 300x VARIO: Do not place the pumping unit on soft
surfaces (e.g., rubber foam) during operation. This may
reduce or block the fans’ air supply. Keep a minimum distance of 8 in (20 cm) between the cooling fan and surrounding items (e.g., housing, walls, etc.). Do not cover
the pumping unit.
Position the controller CVC 3000 and its vacuum line in
such a way that condensate cannot ow 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.
Secure coolant hoses at the hose nozzles (e.g., with hose
clamp) to prevent their accidental slipping.
Comply with all applicable and relevant safety require-
ments (regulations and guidelines). Implement the re-
Page 17
page 17 of 129
quired actions and adopt suitable safety measures.
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.
+ Pay attention to the permissible maximum ambient
and gas inlet temperatures (see “Technical data”, pg.
NOTICE
26).
• Adopt suitable measures in case of differences from
recommended conditions, e.g., using the equipment
outdoors, installation in altitudes of more than 6500 ft
(2000 m) above mean sea level, conductive pollution or
external condensation on the pump.
• Do not operate this product near ames.
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

substances, see section “Technical data”, pg. 26.
When changing the substances pumped, we recom-
mend 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.
Safety during operation
➨ Adopt suitable measures to prevent the release of dan-
gerous, toxic, explosive, corrosive, noxious or polluting
uids, 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 for-
mation 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 gas ballast or venting, if necessary.
➨ Drain appropriately or otherwise remove any potential-
ly explosive mixtures at the outlet of the pump, or dilute
them with inert gas 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.
Page 20
page 20 of 129
+ Never aspirate liquids or dust into the pump.
+ Make sure that the exhaust pipeline cannot become
blocked.
+ Check the overpressure safety relief device at the ex-
haust waste vapor condenser at appropriate intervals.
+ Attention: At pressures above approximately 795 Torr
(1060 mbar) the pressure reading becomes incorrect
due to saturation of the pressure transducer. The dis-
play ashes. 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 uoroelastomers). Use appropriate protective clothing and
safety goggles.
+ Use only original manufacturer’s spare parts and
accessories. Otherwise the safety and performance of
the equipment, as well as the electromagnetic compatibility of the equipment might be reduced.
The CE mark or the cTÜVus mark may be voided if not
using original manufacturer’s spare parts.
+ 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,
Page 21
page 21 of 129
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 ngers
can be caught or drawn in at the inlet of the pump. Nev-
er insert ngers or drop any other object into the inlet or
outlet.
• Pumping at high inlet pressure may lead to overpressure at the gas ballast valve. Pumped gases or condensate might be expelled if the valve is open. If an
inert gas supply is connected to the gas ballast, ensure
that its inlet pipeline is not contaminated.
• 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 pro-
cess 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: conguration) is
enabled.
• 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
NOTICE
from hot surfaces or electric sparks. Ensure that hot
surfaces of the pump do not cause burns. Provide a
suitable contact guard if necessary.
• Ensure that the coolant outlet pipe at the waste vapor
condenser is always free and that it cannot get blocked.
Do not start the pump if the pressure difference between
inlet and outlet exceeds 16 psi (1.1 bar) at maximum.
Page 22
page 22 of 129
Prevent the backpressure of gases and the backow of
condensates at the outlet.
Check the liquid level in the catchpots or in the collecting
ask regularly and drain condensate in time to prevent
overlling. Install a level sensor (see ”Accessories”, pg.
92) for monitoring, if necessary.
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
NOTICE
thermal cutout in the winding.
Note: Only manual reset is possible. Press the START/
STOP key at the controller to conrm the error message.
Switch off the pump and disconnect from the power source.
Identify and eliminate the cause of failure. Wait approx.
ve minutes before restarting the pump.
Maintenance and repair
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. 122) 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.
In case of normal wear, the lifetime of the diaphragms and
valves is > 10000 operating hours. Bearings have a typical durability of 40000 h.
Page 23
page 23 of 129
➨ Ensure that the pump cannot be operated acciden-
tally. Never operate the pump if covers or other
parts of the pump are disassembled.
➨ Switch off the pump. Disconnect the electrical pow-
er cord and wait two minutes before starting mainte-
nance 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
NOTICE
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 sys-
tem. Allow sufcient cooling of the pump. Separate the
pump from the coolant circuit and drain condensate, if
applicable.
Ensure that maintenance is done only by suitably trained
and supervised technicians. Ensure that the maintenance
technician is familiar with the safety procedures, which relate to the products processed by the pumping system.
Only dismantle the pump as far as necessary.

For equipment labelled with „
tion according to Directive 94/9/EC (ATEX) is valid:
Internal Atm. only, Tech. File Ref.: VAC-EX01.
The classication 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 com-
ponents. If the connected components do not comply with the classication of the VACUUBRAND equipment, the specied category of the
VACUUBRAND equipment is no longer valid.
X see manual“ the following classica-
`
II 3G IIC T3 X,
`
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 25
page 25 of 129
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 specied 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.
Attention: This manual is not available in

Installing a pump in a vacuum system
➨ If dangerous or polluting uids could be released at the
outlet, install an appropriate system to catch and dis-
pose of those uids.
+ 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 al-
ways 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) ab-
solute.
+ Attention: At pressures above approximately 795 Torr
(1060 mbar) the pressure reading becomes incorrect
due to saturation of the pressure transducer. The dis-
play will ash. Release pressure immediately! Risk of
bursting!
+ Particles and dust must not be aspirated. If necessary,
you must install appropriate lters. You must ensure
their suitability concerning gas ow, chemical resis-
tance and resistance to clogging prior to use.
Page 39

+ 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
exible elements as couplings between the pump and
rigid pipes.
Note: Flexible elements will compress or atten 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
NOTICE
pump, especially if the gas ballast valve is open. 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.
Keep a distance of minimum 8 in (20 cm) between fan/
pumping unit and adjacent equipment or casework.
Use connecting hoses with large diameter and keep them
as short as possible to avoid ow losses. Locate the pump
as closely as possible to the application.
Always install outlet tubing descending from the pump to
avoid backow 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.
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.

To reduce pump noise emanating from the pump exhaust
port, connect an exhaust hose or use a silencer (see “Accessories”, pg. 92).
The VACUUBRAND controller CVC 3000 can only be
operated with components compatible with the VACU-
UBRAND VACUU•BUS system, (see “Accessories”, pg.
92).
The vacuum controller CVC 3000 controls VACUUBRAND
diaphragm pumps NT VARIO and VARIO-B, pumping
units PC 30xx VARIO, and optional coolant and venting
valves. Connected components (e.g., venting valve, level
sensor, external pressure transducer 3000 series) are au-
tomatically identied and congurated. Identical compo-
nents must be congurated beforehand; information upon
request.
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).
CVC 3000
The CVC 3000 is equipped with an internal 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.
Pumps NT VARIO and VARIO-B:
Connect the controller CVC 3000 via the VACUU•BUS cable of the NT VARIO or VARIO-B pump to the diaphragm
pump. 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.
Connect the vacuum connection of the controller via hose
or PTFE tubing to the vacuum application. The cross-section of the tubing should be as large as possible.
Inside a vacuum system where evaporation occurs, e.g.,
Page 41
page 41 of 129
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 vacuum controller sensor.
Position the controller CVC 3000 and its vacuum line in
such a way that condensate cannot ow 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. 81.

Exhaust waste vapor condenser:
➨ Assemble the hose nozzles for coolant inlet
(15) and coolant outlet (16) tubing and for
the gas outlet (8) at the exhaust waste vapor
condenser.
The exhaust waste vapor condenser enables
an efcient condensation of the pumped vapors
at the outlet.
+ No backow of condensates.
+ Controlled recovery of condensates.
+ Close to 100% solvent recovery.
+ The isolation cover protects against glass
splinters in case of breakage, acts as ther-

mal isolation to avoid condensation of humidity and is intended to absorb shocks.
➨ Attach the tubing of the coolant circuit to the respective
hose nozzles (hose nozzles for tubing I.D. 1/4”-5/16”
(6-8 mm), see image) at the waste vapor condenser.
NOTICE
Check all hose connections prior to starting operation of
the cooling system.
Secure coolant hoses at the hose nozzles (e.g., with hose
clamps) to prevent their accidentally slipping off.
➨ Prevent the discharge of dangerous gases and vapors
to the surrounding atmosphere. If appropriate, connect
the exhaust line to a suitable treatment system.
+ Never block the gas outlet ((8) hose nozzle for tubing
I.D. 3/8” (10 mm)). The exhaust hose has always to be
unobstructed and without back pressure to enable an
unhindered discharge of gases and protect the pump
valves from damage.
• Note: Install the hoses of the cooling system in a way
to avoid the ow / dripping of condensed water onto the
pumping unit (especially cables and electronic parts,
see also IP degree of protection, “Technical data”, pg.
26.
• Ensure that the coolant outlet tubing is always unob-
structed and that it cannot get blocked.
• Maximum permissible coolant pressure at the exhaust
waste vapor condenser: 87 psi (6 bar) absolute. Outlet
ow must always be unhindered.
• Comply with the maximum permissible coolant pres-
sures of additional components in the coolant circuit
(e.g., coolant valve).
• Avoid overpressure in the coolant circuit (e.g., caused
by blocked or squeezed coolant hoses).
• Only install the optional coolant valve in the supply line
of the exhaust waste vapor condenser.
Page 44
page 44 of 129
During operation
➨ Vent and dispose of potentially dangerous gases or
vapors at the outlet of the pump appropriately.
+ Due to the high compression ratio, the pump might gen-
erate 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
NOTICE
is adequate, especially if the ambient temperature is
elevated.
• 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 insufcient cooling.
• Check compatibility with the maximally permitted
pressure at outlet and the maximum pressure difference between inlet and outlet ports.
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.
If pumping condensable vapors (water vapor, solvents,
etc.), let the pump run with gas ballast to help purge any
condensation in the pump.
Prevent internal condensation, transfer of liquids or dust.
The diaphragms and valves will be damaged, if liquids are
pumped in signicant amounts.
Check the pump regularly for external soiling and depos-
Page 45
page 45 of 129
its. Clean the pump if necessary to avoid an increase of
the pump’s operating temperature.
Operation with silencer (optional) 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.
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 conrm the error message.
Switch off the pump and disconnect the electrical power
cord. Identify and eliminate the cause of failure. Wait ap-
prox. ve 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. Avoid overheating (e.g., due to hot process
gases).
Important notes regarding the use of gas ballast
Gas ballast is a continuous purge to keep the pump’s interior as clean as possible and to reduce the possibility of
condensation inside the pump.
➨ Air and pumped media might react inside the pump or
at the outlet of the pump and form hazardous or explosive mixtures, when you use air rather than inert gas
for the gas ballast. This constitutes a risk of signicant
damage to equipment and/or facilities, a risk of personal injury or even loss of life.
+ Make sure that air/gas intake through the gas ballast
valve can never lead to hazardous, explosive or other-
Page 46
page 46 of 129
wise dangerous mixtures. If in doubt, use inert gas.
NOTICE
gas ballast (9)
(open)
To reduce condensation in the pump, do not pump vapor
before the pump has reached its operating temperature.
Open the gas ballast valve when pumping condensable
vapors. Turn gas ballast cap to open valve.
For condensable vapors (water vapor, sol-
vents, etc.):
- The gas ballast valve is open if the arrow on
the gas ballast cap is pointing towards the
labelling ”GB”.
MD 12C/MV 10C VARIO-B and PC 301x
VARIO: The gas ballast valve is open if the
arrow on the gas ballast cap is pointing away
from the pump‘s inlet.
- With gas ballast valve open, the ultimate vacuum will
be reduced.
- Use inert gas for gas ballast to avoid the formation of
explosive mixtures. A special adapter tting is needed
to connect an inert gas supply line (see “Accessories”,
pg. 92). This adapter replaces the standard gas ballast cap and allows for an inert gas line to be connected
via a KF DN 16 small ange at a maximum supply pressure of 17.5 psi (1.2 bar) absolute.
- Close the gas ballast valve by turning the cap 180°.
In case of low boiling solvents (when the formation of
condensate is unlikely), the use of gas ballast might be
unnecessary. Operating the pump without gas ballast increases the solvent recovery rate at the exhaust waste
vapor condenser.
Important notes concerning the operation of the exhaust waste vapor condenser
➨ Connect the exhaust to a suitable treatment system to
prevent the discharge of dangerous gases and vapors
to the surrounding atmosphere.
Page 47
page 47 of 129
+ Never block the gas outlet ((8) hose nozzle for tubing
I.D. 3/8” (10 mm)). The exhaust hose must always be
unobstructed and without back-pressure to enable an
unhindered discharge of gases.
+ Check the overpressure safety relief device (17) at the
exhaust waste vapor condenser (13) regularly; replace
if necessary. Check especially for deterioration, coalescence and cracks.
• Ensure that the coolant outlet hose is always free and
that it cannot get blocked.
• Maximum permissible coolant pressure at the exhaust
waste vapor condenser: 87 psi (6 bar) absolute
NOTICE
• Comply with the maximum permissible coolant pressures of additional components in the coolant circuit
(e.g., coolant valve).
• We strongly recommend installing an optional coolant
valve (see “Accessories”, pg. 92) in the supply line
of the exhaust vapor condenser to save water and reduce the risk of water spill.
• Avoid overpressure in the coolant circuit (e.g., caused
by blocked or kinked coolant hoses).
In case of condensation: Check the liquid level in both
catchpots (14) or in the collecting ask (20) during operation. Check the liquid level regularly. Do not allow the
catchpots or the collecting ask to overll. Drain catchpots or collecting ask in time to avoid overow. Install a
level sensor (see “Accessories”, pg. 92) for monitoring,
if necessary.
The maximum liquid level is at approximately 80% of the
total lling level to avoid problems when removing the
catchpots or the collecting ask.
Permissible range of coolant temperature at the exhaust
waste vapor condenser:
5 °F to 68 °F (-15°C to +20°C)
Check hose connections prior to starting operation of the
Page 48

cooling system.
Check coolant hoses regularly during operation.
Removing the catchpots:
Catchpot or collecting ask at outlet:
Remove joint clip. Remove catchpot or collecting ask and
drain condensate.
Catchpot at inlet:
Admit air or inert gas (via the pump inlet) to restore atmospheric pressure in the catchpot before attempting
removal. Remove joint clip. Remove catchpot and drain
condensate.
NOTICE
Catchpot at inlet (PC 301x VARIO):
Admit air or inert gas (via the pump inlet) to restore atmospheric pressure in the catchpot before attempting removal. Open drain screw (19) and drain condensate. Close
drain screw.
Reattach drained catchpots.
+ Important: Comply with regulations when disposing
of solvents/condensates. Recycle if possible; purify if
contaminated.

Notes on selecting the function
The CVC 3000 controller can be adapted to the specic 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 conguration 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 re-
new the conguration.
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 ve functions and one conguration menu,
see section ”Menu guide”. Each of these functions involves different menu
options, which are presented automatically and reect the connected
components. The types of components connected (e.g., valves) determine the active menu items.

Pump down function
➨ Continuous pumping with pressure and time settings
• Operation on demand of a speed controlled NT VARIO / VARIO-B
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 selec-
tion ”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.
Page 58

Vac Control function
➨ Vacuum control to a preset vacuum value
• Operation on demand of a speed controlled pump (NT VARIO /
VARIO-B)
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 suc-
tions or ltrations. 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

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 ”non-
critical” processes to reduce process time. Usually setting the ”Sensitiv-
ity” 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 pro-
cess. 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” species 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 63
page 63 of 129
+ Duration: ”Duration” determines the total process time since control
start.
The ”Duration” is adjustable between 1-1440 minutes (24 h) or can
be set to ”Off”. A preset ”Duration” (process time) has no effect, if the
process is stopped earlier by reaching the preset ”Minimum”.

VACUULAN function
➨ Optimizes vacuum control for vacuum networks
(e.g., VACUUBRAND VACUU•LAN)
➨ Permits on-demand operation of a speed-controlled pump
(NT VARIO/VARIO-B)
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 (2-
1060 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
”Off” (”Off” means that the pump stops immediately when the pressure
drops below ”Set vacuum”.).

+ Set ”Set vacuum” to a value which does not lead to evaporation of the
solvent.
+ If necessary, set value for ”Speed” (high or low pumping speed). Re-
duce the speed in case of fast sedimentation (formation of a lter cake).
+ Set ”Maximum” pressure setting so that pump will switch off at the end
of the ltration process, or in the event that a lter cake cracks, leading
to a sudden pressure increase.
+ Start process by pressing ”START/STOP” key.
+ Tip for ltration: Adjust preset pressure to a value well above the
boiling pressure of the solvent (e.g., for water >>15 Torr (20 mbar)).

Vacuum for distillation and evaporation
(e.g., rotary evaporator)
Fully automatic determination and adaptation of the boiling point
(recommended)
+ Select ”Auto mode”.
+ Start process by pressing ”START/STOP” key.
+ The ”Auto mode” allows a fully automatic distillation even if the boiling
vacuum is unknown. In case of solvent mixtures the vacuum is reduced
until all solvents or volatile components are evaporated (with respect
to the ultimate vacuum of the pump and the bath temperature).
+ If ”Minimum” is set, the controller switches off the pump when the pre-
set vacuum value is reached. The ”Minimum” should be well below
the boiling vacuum of the solvent to be evaporated and above the ultimate vacuum attainable in the apparatus. If the ”Minimum” is set to
”Auto” , the controller automatically switches off the pump at the end
of the evaporation (recommended for large solvent quantities only).
The setting of ”Duration” (process runtime) has no effect if the pump is
switched off due to ”Minimum” before ”Duration” is over.
Page 71
page 71 of 129
+ When setting a value for ”Duration” the controller switches off the
pump when ”Duration” has passed even if a preset ”Minimum” is still
not reached.
+ If neither ”Minimum” nor ”Duration” is preset, pumping down has to be
nished by pressing the ”START/STOP” key.
alternatively:
Semi-automatic distillation and evaporation
+ Select function ”Pump down”.
+ Start process by pressing ”START/STOP” key.
+ Observe process. As soon as evaporation starts, press ”MODE” key
(switching to ”Vac control”). The vacuum level is kept constant (at the
boiling pressure). Fine tuning of the vacuum value is possible by turning the selection knob.
Pressing ”MODE” key a second time switches to ”Auto mode” causing
the vacuum level to be automatically adapted to changes of the boiling
pressure.
alternatively:
+ Select ”Vac control” function.
+ Set a maximum ”Speed”, to select a faster or slower process.
+ To set ”Maximum” is usually not necessary, unlike ltrations, because
the pressure does not increase at the end of the evaporation.
+ Set a value for ”Duration” if the process should be terminated auto-
matically after a denite time.
+ Set ”Set vacuum” depending on the solvent and the temperature.
+ Start process by pressing ”START” key.
+ To temporarily switch to ”Auto mode”: Press ”MODE” key. The
controller switches to ”Auto mode”. The setting of the controller does
not change due to this switching. After pressing ”START/STOP” key
the controller is in ”Vac control” again.

Adjustment at atmospheric pressure
The vacuum gauge 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
”START/STOP” key, if necessary. In the range between 15
to 525 Torr (20 to 700 mbar) no adjustment is possible;
---- Torr is displayed.
An adjustment at atmospheric pressure is only
possible if the pressure is higher than 525 Torr

* Pressure setting with venting is only possible in ”Vac control” function
if a venting valve is connected and congured, 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.

+ Please read section ”Replacing diaphragms and valves” com-
pletely 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 electri-
cal 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 pro-
cess 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 sufcient cooling of the pump before starting
maintenance.
+ Vent the pump and isolate it from the vacuum sys-
tem before you start maintenance.

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 lled with long-life
lubricant. Under normal operating conditions, the drive
system is maintenance free.
In demanding circumstances, it may be efcient to
check and clean the pump heads on a regular basis. In
normal use, the lifetime of the diaphragms and valves
is more than 10,000 operating hours.
- Prevent internal condensation, transfer of liquids or
dust. The diaphragms and valves will be damaged if
liquid is pumped in signicant 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.
