Fill the pump
IMPORTANT! Danger of damage to the
pump! Dry running will destroy the pump!
■
The pump must be filled with water up to the
overflow before each use so that it can draw
water immediately.
NOTE Fill the suction hose with water before
screwing in place to reduce the suction time.
1. Open filling screw (3) using filter wrench (19/
A).
2. Pour in water through the filling screw until
pump housing (2) is full.
3. Screw in filling screw.

Initial commissioning
During initial commissioning, the PUMP ON LED

line after approx. 90 seconds, the dry running
protection system switches the pump off and the
ALARM LED lights up. Check the suction line, fil-
ter bowl and all screw fittings for leaks, press the
RESET button and carry out initial commissioning
again.
