Dear customer,
Your VACUUBRAND diaphragm pumps should support you for a long time without trouble and with maximal
power. Thanks to our long practical experience we have much information how you could ensure powerful
application and personal safety. Please read these instructions for use before the initial operation of your
pump.
VACUUBRAND diaphragm pumps are the result of many years of experience in construction and practical
operation of these pumps combined with the latest developments in material and manufacturing technology.
Our quality maxim is the ”zero fault principle”:
Every diaphragm pump, leaving our company, is tested intensively including an endurance run of 18 hours.
Therefore also faults, which occur rarely, are identified and can be eliminated immediately.
The achievement of the specifications after the endurance run is tested for every pump.
Every VACUUBRAND pump achieves the specifications. We feel obliged to this high quality standard.
We know that the vacuum pump can not take a part of your real work and hope that our products contribute
to an effective and trouble-free realisation of your work.
Yours
VACUUBRAND GMBH + CO KG

☞ Make sure that the individual components are only connected, combined and oper-
ated according to their design and as indicated in the instructions for use.
page 4 of 48
Comply with national safety regulations and safety requirements concerning the
use of vacuum and electrical equipment.
☞ Equipment must be connected only to a suitably fused and protected electrical
supply and a suitable earth point. Failure to connect the motor to ground may result
in deadly electrical shock.
☞ The supply cable may be fitted with a moulded European IEC plug or a plug suitable
for your local electrical supply. If the plug has been removed or has to be removed,
the cable will contain wires colour coded as follows: green or green and yellow:
earth; blue or white: neutral; brown or black: live.
☞ Check that mains voltage and current conform with the equipment (see rating plate).
☞ If the equipment is brought from cold environment into a room for operation, allow
the equipment to warm up (pay attention to water condensation on cold surfaces).
☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated.
Comply with all relevant safety requirements (regulations and guidelines) and adopt
suitable safety measures.
☞ Provide a firm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all fittings are secure.
Attention: Flexible elements tend to shrink when evacuated.
Due to the high compression ratio of the pumps, pressure at the outlet port might be
generated being higher than the max. permitted pressure compatible with the mechanical stability of the system.
☞ Comply with maximum permitted pressures and pressure differences, see sec-
tion ”Technical data”. Do not operate the pump with overpressure at the inlet.
Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipeline cannot become blocked). If you have an exhaust in-line valve, make sure that you
cannot operate the equipment with the valve closed. Risk of bursting!
☞ Ensure that the system design does not allow the exhaust pipeline to become
blocked.
☞ Max. permitted pressure at the pressure transducer: 1.5 bar (absolute).
☞ Ensure that the system design does not allow the coolant outlet pipeline to
become blocked.

☞ Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their
accidental slipping.
☞ Check liquid level in both catchpots regularly and drain condensate in time.
☞ Check the overpressure safety relief device at the exhaust waste vapour con-
denser in appropriate intervals.
☞ Avoid overpressure of more than 0.2 bar in case inert gas is connected.
☞ The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
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, especially directive IEC 1010. This directive
gives in detail conditions, under which the equipment can be operated safely (see also
IP degree of protection).
☞ Adopt suitable measures in case of differences, e. g. using the equipment outdoors,
installation in altitudes of more than 1000 m above mean sea level, conductive
pollution or dewiness.
Pay attention to symbol ”hot surfaces” on the equipment.
☞ Adopt suitable measures to prevent any danger arising from hot surfaces or the
formation of electric sparks.
The pumps have no approval for operation in or for pumping of potentially explosive atmospheres.
If pumping different substances, purge the pump with inert gas prior to changing the
pumped media in order to pump out residues and to avoid reactions of the pumped
substances with each other with and the pump material. Ensure that the materials of
the wetted parts are compatible with the pumped substances, see section ”Technical
data”.
Take into consideration interactions and chemical reactions of the pumped media.
The pumps are not suitable for pumping substances which may form deposits inside
the pump.
☞ If there is a danger of the formation of deposits in the pump chamber (check inlet
and outlet of the pump) inspect the pump chamber regularly and clean if necessary.
The pumps are not suitable to pump unstable substances and substances which
react explosively under impact (mechanical stress) and/or when being exposed to
elevated temperatures without air.
The pumps are not suitable to pump self inflammable substances, substances which
are inflammable without air and explosive substances.
The pumps are not suitable for pumping dust and have no approval for operation
below ground.
☞ Adopt suitable measures to prevent the release of dangerous, explosive, corrosive
or polluting fluids.
☞ Use inert gas for gas ballast or venting if necessary.
☞ The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber or at the outlet. For example in case of a diaphragm crack, mechanically generated sparks, hot surfaces or static electricity
may ignite these mixtures.
☞ Take adequate precautions to protect people from the effects of dangerous sub-
stances (chemicals, thermal decomposition products of fluoroelastomers), wear
appropriate safety-clothing and safety glasses.
☞ Comply with applicable regulations when disposing of chemicals. Take into consid-
eration that chemicals may be polluted.

The motor is shut down by a thermal cutout in the winding.
☞ Attention: Manual reset is necessary. Switch off the pump or isolate the equipment
from mains. Wait approx. five minutes before restarting the pump.
☞ Avoid high heat supply (e. g. due to hot process gases).
☞ Ensure sufficient air admittance if pump is installed in a housing.
☞ Attention: In case of supply voltage below 100V, the lock of the cutout might be
restricted and the pump might restart on its own after sufficient cooling down. Take
suitable precautions, if an automatic restart of the pump may lead to a critical
dangerous situation.
Due to the residual leak rate of the equipment, there may be 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.
Pumping at high inlet pressure may lead to overpressure at the gas ballast valve.
☞ Pumped gases or condensate might be pushed out in case the valve is open.
☞ If an inert gas supply is connected, ensure that the inlet pipeline is not contami-
nated.
The controller is equipped with a short circuit proof transformer with an integrated
overload protection (no fuses).
Ensure that in case of failure the pump and the vacuum system always will turn into a
safe status.
☞ In case of diaphragm cracks or leaks in the manifold pumped substances might be
released into the environment or into the pump housing. To reduce the risk of leaks,
ask for a diaphragm pump with additional safety diaphragm.
☞ Comply with notes on operation and use and maintenance.
☞ Failure of the pump (e. g. due to power failure) must not lead to a critical dangerous
situation under any circumstances.
Electronic equipment is never 100% fail-safe. This may lead to an indefinite status of
the equipment. Provide protective measures against misfunction and failure.
☞ Operating the pump, stand still of the pump or operating the venting valve must not
lead to a critical dangerous situation under any circumstances.
Use only genuine spare parts and accessories.
☞ Otherwise safety and performance of the equipment as well as the electromagnetic
compatibility of the equipment might be reduced.
Possibly the CE mark or the C/US conformity becomes void if not using genuine
spare parts.
The A-weighed emission sound pressure level of the pump does not exceed 70 dB(A).
Measurement according to EN ISO 2151:2004 and EN ISO 3744:1995 with standard
silencer or exhaust tube at outlet.
Ensure that maintenance is done only by suitable trained and supervised technicians. Ensure that the maintenance technician is familiar with the safety procedures
which relate to the product processed by the vacuum system and that the equipment,
if necessary, is appropriately decontaminated before starting maintenance.
Comply with local and national safety regulations.
Wear parts have to be replaced regularly. In case of normal wear the lifetime of the
diaphragms and valves is > 10000 operating hours. Bearings have a typical durability
of 40000 h. Motor capacitors have a typical durability in the range of 10000 to 40000 h
depending strongly on the operation conditions like ambient temperature, humidity or load.

☞ Check every capacitor regularly by measuring its capacity and estimating its opera-
tion time. Exchange old capacitors early enough to prevent a failure. If an overaged
motor capacitor fails it might get hot and even melt and may cause a flame to form
which could be dangerous for persons and equipment in the vicinity. The capacitors have to be replaced by an electrician.
➨ Isolate equipment from mains and wait two minutes before starting mainte-
nance to allow the capacitors to discharge.
➨ Before starting maintenance, wait two minutes after isolating the equipment from
mains to allow the capacitors to discharge.
☞ Ensure that the pump cannot be operated accidentally. Never operate the pump
if covers or other parts of the pump are disassembled. Never operate a defective or damaged pump.
☞ Attention: The pump might be contaminated with process chemicals which have
been pumped during operation. Ensure that the pump is decontaminated before
maintenance and take adequate precautions to protect people from the effects of
dangerous substances if contamination has occurred.
☞ Before starting maintenance vent the pump, isolate the pump and other compo-
nents from the vacuum system. Allow sufficient cooling of the pump. Drain condensate, if applicable.
In order to comply with law (occupational, health and safety regulations, safety at work
law and regulations for environmental protection) vacuum pumps, components and
measuring instruments returned to the manufacturer can be repaired only when certain
procedures (see section ”Notes on return to the factory”) are followed.

➨ Attach the pipelines of the coolant circuit to the respective hose nozzles (see im-
age) at the waste vapour condenser. Check hose connections prior to starting operation of the cooling system.
➨ Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their
accidental slipping.
☞ Ensure that the coolant outlet pipeline is always free and that it cannot get blocked.
☞ Install an optional coolant valve always only in the inlet line of the exhaust waste
vapour condenser.
The exhaust waste vapour condenser enables an efficient
condensation of the pumped vapours at the outlet.
☞ No backflow of condensates.
☞ Controlled recovery of condensates.
☞ Next to 100% solvent recovery.
☞ The isolation cover protects against glass splinters in case
of breaking, acts as thermal isolation to avoid condensation
of humidity and is intended to absorb shocks.
☞ The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline has
always to be free and pressureless to enable an unhindered discharge of gases.
☞ Connect the exhaust to a suitable treatment plant to prevent the discharge of dan-
gerous gases and vapours to the surrounding atmosphere.

Installing in a vacuum system
☞ Avoid throttling losses by using connecting pipes with large diameter and keep
them as short as possible.
☞ Reduce the transmission of vibration and prevent loading due to rigid pipelines.
Insert elastic hoses or flexible elements as couplings between the pump and rigid
pipes. Attention: Flexible elements tend to shrink when evacuated.
☞ Use a suitable valve to isolate the pump from the vacuum system to allow the
pump to warm up before condensable vapours are pumped or to clean the pump
before it is switched off.
☞ Connect the exhaust to a suitable treatment plant to prevent the discharge of dan-
gerous gases and vapours to the surrounding atmosphere. Use a catchpot to prevent the drainage of contaminated condensate back into the pump.
Prior to use
☞ Max. ambient temperature: 40 °C
☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated. Keep a distance of min. 20 cm between fans and ambient
parts.
☞ If pump is installed in altitudes of more than 1000 m above mean sea level check
compatibility with applicable safety requirements, e. g. IEC 60034 (motor may overheat due to insufficient cooling).
☞ If the gas ballast valve is open, a power failure may cause unintentional ventilation
of the pump. In case this constitutes a potential source of danger, take appropriate
safety measures.
☞ When assembling, ensure vacuum-tightness. After assembly, check the complete
system for leaks.
During operation
Do not start pump if pressure difference between inlet and outlet port exceeds max.
1 bar. Attempts to start pump at higher pressure difference may cause blockade and
damage of the motor.
☞ Check compatibility with max. permitted pressure at outlet and max. pressure
difference between inlet and outlet ports.
Due to the high compression ratio of the pumps, pressure at the outlet port might be
generated being higher than the max. permitted pressure compatible with the mechanical
stability of the system.
The pump achieves its pumping speed, ultimate total vacuum and vapour pumping
rate only at operating temperature (after approx. 15 minutes).
☞ Prevent internal condensation, transfer of liquids or dust. The diaphragm and valves
will be damaged, if liquids or dust are pumped in significant amounts.
☞ Let the pump run with gas ballast to reduce condensation of pumped substances
(water vapour, solvents, ....) in the pump.
Motor is shut down by a thermal cutout in the winding.
☞ Manual reset is necessary. Switch off the pump or isolate the equipment from mains.
Wait approx. five minutes before restarting the pump. Identify cause of failure and
eliminate.
☞ Attention: In case of supply voltage below 100V, the lock of the cutout might be
restricted and the pump might restart on its own after sufficient cooling down. Take
suitable precautions, if an automatic restart of the pump may lead to a critical
dangerous situation
