5. Initial Start-up
6. Maintenance
If there is a risk of freezing, the pump must be drained
ahead of time. For this purpose open the drain plug in order
to drain off all liquid. Also drain all pipes subject to freezing.
Before doing any maintenance work, switch off the pump
and disconnect it from the power supply.

Caution
Unscrew the ring nut and lift off the transparent lid. Slowly fill
the pump with clean water until the water level reaches the
inlet connection. Put on the transparent lid and tighten the
ring nut by hand. Never let the pump run dry, not even to
verify the direction of rotation! Ensure that the valves
installed on the suction and pressure lines are completely
open. Before initial start-up and after extended periods of
downtime make sure the pump shaft turns freely.
Caution
The strainer basket must be cleaned at regular intervals. A
full or dirty strainer will impair the pumps flow rate and the
filtration. For longer periods of downtime we highly
recommend to completely drain the pump and clean it.
