☞ Make sure that the individual components are only connected, combined and op-
erated according to their design and as indicated in the instructions for use.
page 4 of 28
Obey national safety regulations and safety requirements concerning the use of
vacuum and electrical equipment.
☞ Ensure that the equipment is suitable for the intended operation.
☞ 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.
The main on/off switch is located sidewise at the terminal box.
☞ Equipment must be connected only to a suitable fused and protected electrical
supply and a suitable earth point (recommended slow-blow fuse 0.85 A for 230 V).
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 suit-
able 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).
Direction of rotation of pumps with three phase motor: Pumps wired ready for
connection with three phase motor are supplied with a mains plug. The electrical
wiring is laid out for a right-handed rotary field.
Checking the direction of rotation:
Switch on pump for a few seconds and check if the pump sucks at inlet. If no
suction occurs switch of pump immediately. The three phase socket has to be
checked and if necessary corrected by an electrician.
☞ 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).
☞ Ensure that installation is in compliance with limitations from the degree of protec-
tion, see section ”Technical Data”.
Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipe-
line cannot get blocked). If you have an exhaust-isolation 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 get blocked.
☞ 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.

Pay attention to symbol ”hot surfaces” on the equipment (according to IEC 1010 recommendation).
☞ Adopt suitable measures to prevent any danger arising from the formation of hot
surfaces or electric sparks.
☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated.
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 out-
doors, installation in altitudes of more than 1000 m above mean sea level, conductive pollution or moisture.
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 in-
side 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 neces-
sary.
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.
Ensure that the materials of the wetted parts are compatible with the pumped
substances, see section ”Technical data”.
☞ If residues can occur or if aggressive or condensable substances may enter the
product, install suitable protection (e.g. gas washing bottle).
☞ Adopt suitable measures to prevent the release of dangerous, explosive, corrosive
or polluting fluids.
☞ 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.
☞ Observe applicable regulations when disposing of chemicals which may be con-
taminated by pumped substances.
☞ The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber. In case of a diaphragm crack, mechanically
generated sparks, hot surfaces or static electricity may ignite these mixtures.
Important note on working with condensable vapours:
☞ Before commencing evacuation, allow pump to reach operating temperature, make
sure that gas ballast valve remains open all times and do not permit vapour inlet
pressure to exceed the permitted maximum.

Check oil level and condition of oil at regular intervals.
If a single-phase motor overheats, it is shut down by an embedded thermostatic
cutout in the winding. Three-phase motors are equipped with a circuit-breaker which
isolates all the poles in the event of an overload. Manual reset is necessary. Determine and eliminate cause of failure.
☞ Single-phase motor: Switch off pump or isolate the equipment from mains. Wait
approx. five minutes before restarting the pump.
☞ Three-phase motor: Wait approx. two minutes before restarting the pump.
☞ Avoid heat supply (e.g. due to process gases).
☞ Ensure sufficient air admittance if pump is installed in a housing.
Ensure that in case of failure the pump and the vacuum system always will turn into a
safe status.
☞ Failure of the pump (e. g. due to power failure) must not lead to a critical dangerous
situation under any circumstances.
☞ Obey especially notes on operation and use and maintenance.
☞ Operating the pump, stand still of the pump or operating the air admittance valve
must not lead to a critical or dangerous situation under any circumstances.
Under normal conditions, pump oils and lubrications are not toxic and their use entails
no danger. Certain hazards are, however, associated with some of these products.
The following precautions must be adopted during use and operation in order to meet
health and safety requirements.
Adopt precautionary measures (e. g. wear appropriate safety-clothing and protective goggles) to avoid excessive contact with the skin and possible skin irritations
(including dermatitis).
Do not inhale or swallow. Maintain adequate levels of hygiene and cleanliness.
Ensure that the pump location is well ventilated and that possible toxic effects of certain vapours are avoided.
☞ Use suitable collecting and disposing systems if necessary.
☞ Observe all relevant statutory requirements and regulations concerning the stor-
age and disposal of oils.
Even if the medium pumped is air or an inert gas, the discharge from rotary vane
pumps contains small quantities of oil vapour and crack products. These substances
are contaminating particularly in closed spaces or in absence of adequate ventilation.
☞ Gases and vapours discharged from the pump should be transported outwards by
means of hoses.
The dependability and operatability of the pump is not guaranteed if other-make filters
are used.
The discharge from the pump invariably contains the evacuated gas or vapours!
☞ Prevent any dangerous reactions with oil or vapours or the impermissible or dan-
gerous occurrence of emissions.
Use only oil of the recommended type.
Other oils or operating fluids may cause dangers or damage of the pump.
Use special oils for the pump if:
☞ The pump operates in the vicinity of potential ignition sources.
☞ Oxygen or other flammable gases account for a large proportion of the evacuated
gases.

Do not allow oils to be poured into or enter the drainage system or other bodies of
water. Spillage can cause accidents! Use suitable means for removing spilt oil.
☞ Observe all relevant statutory requirements and regulations concerning the use,
storage and disposal of oil.
Use only genuine spare parts and accessories.
☞ Otherwise safety and performance of the equipment as well as the electromag-
netic compatibility of the equipment might be reduced.
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.
Obey local and national safety regulations.
Before starting maintenance vent the system, isolate the pump and other components from the vacuum system and the electrical supply. Drain condensate if applicable, avoid the release of pollutants. Allow sufficient cooling of the pump. 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.
Before starting maintenance, wait two minutes after isolating the equipment from
mains to allow the capacitors to discharge.
Attention: The pump might be contaminated with the process chemicals that 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.
☞ Wear appropriate safety-clothing when you come in contact with contaminated
components.
In case of normal wear the lifetime of the motor capacitors is about 40000 operating
hours. The capacitors have to be replaced by an electrician.
As laid down in the statutory regulations ( occupational, health and safety regulations
and regulations for environmental protection), vacuum pumps returned to the manufacturer can be repaired only under certain conditions, see section ”Notes on return to
the factory”.
☞ Avoid any contamination of pumped substances or of the environment.

a.) Partial vacuum of permanent gases measured at pump inlet.
b.) The total vacuum, e.g. measured with thermal-conductivity vacuummeter, is higher than the partial vacuum because the
former includes the vapour pressure of the pump oil and other condensable vapours (e.g. water); the condition of the
oil (cleanliness, content of hydrocarbons with higher partial pressures) is crucial for this value.
c.) The maximum inlet pressure for water vapour, or rather the maximum inlet pressure for vapour, cannot be specified in
accordance with PNEUROP because it cannot be determined for the HYBRID pump in accordance with this standard.
On account of the considerably reduced pressure in the oil-sealed part of the RC 5, however, the value is considerably
higher than that of a conventional oil-sealed rotary-vane pump.
d.) With inlet sealed and without gas ballast.
e.) Oil temperature and pressure in the oil reservoir are the relevant parameters for maximum inlet pressure for vapours and
chemical resistance.
