•
necessary, even more often:
- Drain water out and dismantle the pump. Flush pump housing and 3D-needle wheel with clean
water and, if necessary, use a brush. The same should be done with the air injection nozzle.

pump gets noisy, the pump head and rotor (Fig. 2) have to be cleaned. If the impeller is damaged,
it has to be replaced.

nozzle with a thin brush or blunt instrument and re-assemble the pump again.
