Electronic equipment is never 100% fail-safe. This may

lead to an indenite 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. ve 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 sufcient

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.
