Shutdown:
Short-term:
Has the pump been exposed to condensate?
➨ Allow the pump to continue to run at atmospheric pressure and with a free exhaust
pipeline for a few minutes.
Has the pump been exposed to media which may damage the pump materials or form
deposits?
☞ Check and clean pump heads if necessary.
Long-term:
➨ Take measures as described in section short-term shutdown.
➨ Separate pump from the apparatus.
➨ Close inlet and outlet port (e. g. with transport caps).
➨ Store the pump in dry conditions.
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. 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
