Electronic equipment is never 100% fail-safe. This may
lead to an indefinite status of the equipment. Failure of the
pumping unit (e. g., by power failure) or connected compo-
nents, or change of parameters must not lead to a critically
dangerous situation under any circumstances. In case of
diaphragm cracks or leaks in the manifold, pumped sub-
stances might be released into the environment or into the
pump housing. Comply especially with notes on operation
and use and maintenance.
• 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 arising
from hot surfaces or electric sparks. Ensure that hot
surfaces of the pump do not cause burns. Provide a
suitable contact guard if necessary.
In case of overload, the motor is shut down by a self-hold
thermal cutout in the winding. Attention: Reset possible
only manually. Switch off the pump or isolate the equip-
ment from power supply. Identify and eliminate the cause
of failure. Wait approx. five minutes before restarting the
pump.
• Attention: In case of supply voltage below 100V (100-
120V version), 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.
Maintenance and repair
Wear parts have to be replaced regularly. Under typi-
cal operating conditions, the projected lifetime of the dia-
phragms and valves is > 15000 operating hours. Bearings
have a typical durability of 40000 h. Motor capacitors have
a typical durability in the range of 10000 to 40000 h de-
pending strongly on the operating conditions like ambient
temperature, humidity or load.
