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. Identify and eliminate the cause of failure. Wait approx. five minutes before
restarting the pump.
☞ Attention: In case of supply voltage below 100V, the lock of the cutout might be
restricted and the pump might restart on its own after sufficient cooling down. Take
suitable precautions, if an automatic restart of the pump may lead to a critical
dangerous situation
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.
Ensure that in case of failure the pump and the 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.
☞ Obey especially notes on operation and use and maintenance.
Use only genuine spare parts and accessories.
☞ Otherwise safety and performance of the equipment as well as the electromag-
netic compatibility of the equipment might be reduced.
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 technicians.
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.
Obey local and national safety regulations.
Before starting maintenance vent the pump, isolate the pump and other compo-
nents from the system and the electrical supply and allow sufficient cooling of the
pump.
Before starting maintenance, wait two minutes after isolating the equipment from
mains to allow the capacitors to discharge.
In case of normal wear the lifetime of the capacitors is about 40000 operating hours.
The capacitors have to be replaced by an electrician.
In order to comply with law (occupational, health and safety regulations, safety at work
law and regulations for environmental protection) vacuum pumps, components and
measuring instruments returned to the manufacturer can be repaired only when cer-
tain procedures (see section ”Notes on return to the factory”) are followed.
