Maintenance advise

The pump is largely maintenance-free. For a long operating life we recommend regular checks
and maintenance.
Attention!
Before every maintenance the pump must be switched off, so disconnect the pump from the
power supply.

During long periods of non-use the pump must be rinsed thoroughly with water, completely
emptied and stored in a dry environment.

In case of danger frost the pump must be completely emptied.

After longer non-operation periods, check if the rotor turning is carried out properly by briefly
switching on and off.

In case the pump is blocked, connect the pressure line to the water line and remove the suction
hose. Open the water line. Turn on the pump for sevaral times for approx. two seconds. This way
blockages can be cleared in most cases.
