10. Maintenance instructions
앬
The pump is basically maintenance free. To
ensure a long service life, however, we
recommend regular checks and care.
Warning!
Before every servicing, switch off the pump
and remove the plug from the socket.
앬
If the pump is not going to be used for a long time
or has to be removed for the winter months, rinse
it out with water, empty it completely and allow it
to dry.
앬
If there is a risk of frost, the pump must be
emptied completely.
앬
After long stoppages, make sure the rotor turns
correctly by briefly switching the pump on and off.
앬
If the pump becomes blocked, connect the
pressure line to the water line and remove the
intake hose. Open the water line. Switch on the
pump several times for approx. 2 seconds. Most
blockages can be removed in this way.
11. Replacing the mains cable
Warning! Disconnect the pump from the mains!
If the mains cable is defective, it must be
replaced by an electrician.
