Maintenance and cleaning

Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures:
− Prior to reaching into the water, disconnect the power supply to all units used in the water.
− Disconnect the power plug prior to carrying out work on the unit.
Note:
− Check and clean the water outlet into the pond at regular intervals.
− Clean the filters at regular intervals (e.g. every four weeks), however, at the latest when cloudy or dirty water from
the water outlet returns to the garden pond.
− Carry out quick cleaning first. Should this prove insufficient, clean the entire unit.
− A blocked filter could lead to leakages.
− Never use chemical cleaning agents.
Quick cleaning (D)
− Switch off the filter pump.
− Remove hose from the filter outlet by turning off the union nut (1).
− Remove hose from the filter inlet by turning off the union nut and screw on the filter outlet (2).
− Screw a dirt drain hose with stepped hose adapter on the filter inlet.
− Switch on the filter pump.
− Vigorously pull on the cleaning handle and „pump" several times (3). In this manner, the foam filters are
mechanically cleaned until the draining water is clear.
− Switch off the filter pump.
− Remove the dirt drain hose and correctly reconnect the hoses for normal operation (Figure A).
