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. Deter-
mine 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 protec-
tive 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 cer-
tain 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.
