• Complywithapplicableregulationswhendisposingofchemicals.Takeintocon-
sideration that chemicals may be polluted.
Take adequate precautions to protect people from the effects of dangerous sub-
stances(chemicals,thermaldecompositionproductsofuoroelastomers),wear
appropriate safety-clothing and safety glasses.
• Useonlygenuine spare parts and accessories. Otherwise safety and perform-
ance of the equipment as well as the electromagnetic compatibility of the equip-
ment might be reduced.
Possibly the CE mark becomes void if not using genuine spare parts.
• Failure of the pump (e.g. due to power failure) or of connected components,
parts of the supply or change of parameters must not lead to a critical dangerous
situation under any circumstances. In case of diaphragm cracks or leaks in the
manifold pumped substances might be released into the environment or into the
pump housing or motor. Comply especially with notes on operation and use and
maintenance.
• Duetotheresidualleak rate of the equipment,theremight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.

regularly and drain condensate in time.
Donot startthe pumpif thepressure differencebetweeninletandoutletport ex-
ceeds1.1baratmaximum.
Preventanybackpressureofgasesandthebackowofcondensates.
Never suck liquids or dust into the pump.
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.
The motor is protected by a temperature sensor at the circuit board: Current
limitation if the temperature at the circuit board is higher than 70°C, switching off the
pump if the temperature is higher than 85°C. In case of blockade of the motor (after
10 attempts to start-up) the pump is switched off.
If the pump is switched off due to safety measures, manual reset is necessary. Isolate
the pump from mains. Eliminate the cause of failure before restarting the pump.
TheA-weighted 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.
