Due to the residual leak rate of the equipment, there may 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.
Pumping at high inlet pressure may lead to overpressure at the gas ballast valve.
☞ Pumped gases or condensate might be pushed out in case the valve is open.
☞ If an inert gas supply is connected, ensure that the inlet pipeline cannot become
contaminated.
The controller is equipped with a short circuit proof transformer with an integrated
overload protection (no fuses).
The pump is equipped with a frequency converter which checks the electronic sys-
tem of the converter and of the motor of the pump extensively. The motor is protected
by an additional thermal cutout (see section “Troubleshooting”).
Electronic equipment is never 100% fail-safe. This may lead to an indefinite status of the
equipment. Ensure that in case of failure the pump and the vacuum system always will
turn into a safe status. Provide protective measures against malfunction and failure.
☞ Operating the pump with high or low frequency, stand still of the pump or operating
an external venting valve must not lead to a critical dangerous situation under any
circumstances.
Ensure that in case of failure the pump and the vacuum system always will turn into a
safe status.
☞ In case of diaphragm cracks or leaks in the manifold pumped substances might be
released into the environment or into the pump housing. To reduce the risk of leaks,
ask for a diaphragm pump with additional safety diaphragm.
☞ Comply especially with notes on operation and use and maintenance.
☞ Failure of the pump (e. g. due to power failure) or of connected components, parts
of the supply (e. g. coolant) or change of parameters (e. g. increase of pressure in
the coolant system) must not lead to a critical dangerous situation under any cir-
cumstances.
Use only genuine spare parts and accessories.
☞ Otherwise safety and performance of the equipment as well as the electromagnetic
compatibility of the equipment might be reduced.
Possibly the CE mark becomes void if not using genuine spare parts.
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.
Ensure that maintenance is done only by suitable trained and supervised techni-
cians. 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.
Comply with local and national safety regulations.
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 durability
of 40000 h.
In case of overload the motor is shut down by a thermal cutout in the winding.
☞ Manual reset is necessary. Switch off the pump or isolate the equipment from mains.
Wait approx. five minutes before restarting the pump.
☞ Avoid high heat supply (e. g. due to hot process gases).
☞ Ensure sufficient air admittance if pump is installed in a housing.
