•
Attention: Due to soiling of the silencer an internal overpressure may build up,
which can damage bearings, diaphragms and valves. Preferably use the hose noz-
zle as outlet and make sure that the exhaust pipeline cannot become blocked.
•
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 fluoroelastomers), wear
appropriate safety-clothing and safety glasses.
•
Use only OEM 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 or the cTÜVus mark become void
if not using OEM spare parts.
Do not start the pump if the pressure difference between inlet and outlet port ex-
ceeds 1.1 bar at maximum.
Prevent the backpressure of gases and the backflow 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, parts
of the supply or change of parameters must not lead to a critical dangerous situa-
tion 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 hous-
ing 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.
In case of overload the motor is shut down by a self-hold thermal cutout in the
winding.
Three-phase motors are equipped with a circuit-breaker which isolates all poles
in the event of an overload.
Attention: Reset possible only manually. Switch off the pump or isolate the equip-
ment from mains. Identify and eliminate the cause of failure. Allow the pump to cool
down sufficiently before restart. Wait approx. five minutes before restarting the pump.
Avoid high heat supply (e.g. due to hot process gases).
The A-weighed 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.
Maintenance and repair
Wear parts have to be replaced regularly. In case of normal wear the lifetime of
the diaphragms and valves is > 10000 operating hours. Bearings have a typical du-
rability of 40000 h. Motor capacitors have a typical durability in the range of 10000
to 40000 h depending strongly on the operation conditions like ambient temperature,
humidity or load.
