+ Prevent any part of the human body from coming into contact with vacuum.
+ Never aspirate dust into the pump.
+ Make sure that the exhaust pipeline cannot become blocked.
+ Check the overpressure safety relief device at the exhaust waste vapor con-
denser at appropriate intervals.
+ Comply with applicable regulations when disposing of chemicals. Take into con-
sideration that chemicals may be contaminated. Take adequate precautions to
protect people from the effects of dangerous substances (chemicals, thermal de-
composition products of fluoroelastomers). 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 com-
patibility of the equipment might be reduced.
The CE mark or the cTÜVus mark may be voided if not using original manufac-
turer’s spare parts.
+ Failure of the pump (e.g., due to power interruption), failure of connected compo-
nents or of parts of the supply, or a change of parameters must not be allowed to
lead to a dangerous situation under any circumstances. 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.
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.
• 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.
• 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 aris-
ing 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 1.1
bar at maximum.
Prevent the backpressure of gases and the backflow of condensates at the outlet.
Never suck liquids or dust into the pump.
Check the liquid level in the catchpots regularly and drain condensate in time to
prevent overfilling.
Provide appropriate protective measures (i.e precautions which allow for the require-
ments of the respective application) even for the case of failure and malfunction.
Failure of the pump (e.g. due to power failure) or of connected components, of parts
of the supply or change of parameters must not lead to a critical dangerous situation
under any circumstances.
