ll fittings must be sealed with sealing tape; leaks cause air intake and thus hinder or reduce
the water suction.
The suction line should have at least 25=mm (1”) inside diameter; it must be bending, pressure
and vacuum resistant.
The suction line should be as short as possible because the delivery rate decreases with in-
creasing line length.
The suction line should rise steadily towards the pump to prevent air entrapment.
 sufficient water supply must be ensured and the end of the suction line should always be in
the water.

1. Unscrew the water filler plug together with the seal.
2. dd clean water slowly until the pump is filled.
3. If you wish to shorten the suction time, fill the suction line, too.
4. Screw the water filler plug tight with seal again.
5. Open the pressure line (turn on the water tap or spray nozzle) so that the air can escape dur -
