Dear customer,
Your VACUUBRAND pumps are designed to provide you with many years
of trouble-free service with optimal performance. Through our long experience in design, construction and operation of vacuum pumps, combined
with the latest developments in material and manufacturing technology,
we have accumulated a wealth of application and safety insights that we
want to share with you.
Please read these instructions for use before the initial operation of your
pump.
Our quality maxim is the ”zero fault principle”:
Every pump, before leaving our factory, is tested intensively, including an
endurance run of 60 hours. Any faults, even those which occur 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,

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. 18).
+ Do not use any damaged equipment.
• Check the pump‘s oil level.
• The pump is delivered without oil lling. Fill with oil
before operating the pump, see section “Oil change”,
pg. 32.
• Aging of the oil (as indicated by darker color compared
to new oil, strange odor of the oil, particles in the oil, or
contamination) necessitates an oil change.
• Use the handle 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 de-
page 7 of 56
sign and as indicated in the instructions for use.
+ Comply with all notes on correct vacuum and electri-
cal connections; see section “Use and operation”, pg.
22.
+ Do not use the pump to generate pressure.
+ The pumps are designed for ambient temperatures
during operation between +54°F and +104°F (+12°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
NOTICE
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. 18).
+ Do not aspirate particles and dust.
+ Do not pump liquids.
• Ensure that the pump is chemically resistant to the
pumped substances prior to operation.
Use the equipment only as intended, that is, for generation 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-
page 8 of 56
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 pipeline or exhaust valve) at the outlet.
+ Do not permit any uncontrolled pressurizing. Make
sure that the exhaust tubing 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!
+ Always provide a free and pressureless exhaust outlet
to avoid damage to the pump and a risk of bursting.
+ 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. 18. Do not operate the pump
with overpressure at the inlet.
• Avoid overpressure of more than 17.5 psi absolute (1.2
bar absolute) in the event that gas or 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.
• Ensure that no foreign objects can be drawn into the
pump.
page 9 of 56
• 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.
• Use only oil of the recommended type. Other oils or operating uids may cause damage of the pump or dan-
ger.
Use special oils (see “Oil change”, pg. 32) for the
rotary vane pump, if, e.g.,
- acid vapors are pumped.
- extremely high aging stability is required.
- oxygen or other strong oxidizing agents are pumped.
NOTICE
• Take adequate precautions when handling pump uids,
lubricants, and solvents. Use appropriate protective
clothing, safety goggles and protective gloves to avoid
excessive contact with the skin and possible skin irritations (including dermatitis). Do not inhale or swallow!
Ensure that the pump location is well ventilated and
that possible toxic effects of certain vapors are avoided.
Maintain adequate levels of hygiene and cleanliness.
• Comply with all relevant statutory requirements and
regulations concerning the handling, storage and disposal of oil.
Note: Do not allow oils to enter the drainage system
or other bodies of water. Spillage can cause accidents
(slip hazard)!
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 if
necessary to avoid a reduction of ventilation.
The On/Off switch is located at the side of the terminal
box.
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 connections (to avoid overpressure at the outlet,
page 10 of 56
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 require-
ments (regulations and guidelines). Implement the required 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.
18).
• 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.
NOTICE
• 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

Operating conditions
➨ These pumps are not approved for operation in po-
tentially explosive atmospheres. Do not operate the
pumps in potentially explosive atmospheres.
➨ These pumps are not approved for the pumping of po-
tentially explosive atmospheres. Do not pump poten-
tially explosive atmospheres.
➨ The pumps are not suitable to pump any of the sub-
stances listed below.
Do not pump:
- unstable substances
- substances which react explosively under impact
(mechanical stress) without air
- substances which react explosively when being ex-
posed to elevated temperatures without air,
- self inammable substances,
- substances which are inammable without air
- explosive substances.
➨ The pumps are not approved for operation below
ground. Do not operate the pump below ground.
+ The pumps are not suitable for pumping dust.
Do not pump dust.
• Do not pump substances which may form deposits in-
side 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. Deposits may
cause seizing of the pump unit.
• Check the inlet and outlet of the pump and its oil condition, if there is a danger of forming deposits inside the
pump, e.g., in the pump unit of the rotary vane pump or
in the pump chamber of the diaphragm pump. Inspect
the pump regularly and clean if necessary.
page 12 of 56
• Install a cold trap in front of the pump if pumping aggressive or corrosive gases or vapors.
• 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. 18.
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 expansion chamber, in the oil reservoir, in the pump chamber of the diaphragm pump, 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.
page 13 of 56
+ 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.
+ Never aspirate liquids or dust into the pump.
+ Make sure that the exhaust tubing cannot become
blocked. Do not exceed an pressure of 16 psi (1.1 bar)
in the exhaust tubing.
+ 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, oil mist, thermal decomposition products of
uoroelastomers). Use appropriate protective clothing
and safety goggles.
+ Even if the pumped medium is only air or a pure gas,
the discharge from rotary vane pumps will contain small
quantities of oil vapor and petroleum fractions. These
substances are particularly contaminating in closed
spaces or in case of insufcient ventilation.
The discharge from the pump invariably contains the
pumped gases or vapors! Connect a hose to the pump
outlet to dispose of the exhaust gases.
Prevent any dangerous reactions with oil or oil vapors
and the formation of impermissible or dangerous emissions.
+ 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 may be voided if not using original manu-
facturer’s spare parts.
+ Failure of the pump (e.g., due to power interruption),
failure of connected components or of parts of the supply, or a change of parameters must not be allowed to
page 14 of 56
lead to a dangerous situation under any circumstances.
In case of a leak in the manifold or at the shaft seal of
the rotary vane pump, or in case of a diaphragm crack
of the diaphragm pump, pumped substances might be
released into the environment or into the pump housing
or motor.
Especially comply with notes on use and operation and
maintenance.
+ 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 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.
• Check oil level of the rotary vane pump (through sight
glass) every time before starting the pump.
• Check the pump’s oil level and the condition of the oil
on a regular basis.
• 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.
• A power failure or switching off the pump may cause
accidental ventilation of the pump or the vacuum sys-
page 15 of 56
tem, if the manual gas ballast valve of the rotary vane
pump is open. If this constitutes a potential source of
danger, take appropriate safety measures, e.g., install
a solenoid operated gas ballast valve.
NOTICE
Do not start the pump if the pressure difference between
inlet and outlet exceeds 16 psi (1.1 bar) at maximum.
Prevent the backpressure of gases and the backow of
condensates at the outlet.
Important notes on working with condensable vapors:
Allow the pump to attain its operating temperature before
pumping condensable vapors. Keep the vapor inlet pressure below the permitted maximum (see ”Technical data”,
pg. 18).
Open the gas ballast valve in case of pumping signicant
amounts of vapor.
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. Switch off the pump
and disconnect from the power source. Identify and elimi-
nate the cause of failure. Wait approx. ve minutes before
restarting the pump.
Avoid high heat supply (e.g., due to hot process gases).
See “Technical data”, pg. 18, for maximum permitted
gas and ambient temperatures.
Maintenance and repair
NOTICE
In order to comply with laws (occupational, health and
safety regulations, safety at work law and regulations for
page 16 of 56
environmental protection) vacuum pumps, components
and measuring instruments can only be returned when
certain procedures (see section “Notes on return to the
factory”, pg. 50) 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.
Under conditions 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 operation conditions, including ambient temperature, humidity or load.
➨ 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. Avoid the release of
pollutants.
+ Take adequate precautions to protect people from the
effects (e.g., in case of inhalation or skin contact) 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.
page 17 of 56
+ Check every motor capacitor regularly by measuring
its capacity and estimating its time in operation. Replace old capacitors early enough to prevent a failure in
operation. If an old motor capacitor fails, the capacitor
may get hot. It may even melt or emit a ame, which
could be dangerous for persons and equipment in
the vicinity. The capacitors have to be replaced by an
electrician.
+ Vent the pump before starting maintenance. Isolate the
pump and other components from the vacuum system.
Allow sufcient cooling of the pump. Drain condensate,
if applicable.
NOTICE
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.
