Maintenance and cleaning
Recommendation regarding cleaning:
• Clean the unit as required but at least twice a year.
•
When cleaning the pump, pay particular attention to the cleaning of the impeller unit and pump housing.
• Clean the inspection window with cotton swabs.
Do not use chemical cleaning agents. Chemical cleaning agents kill the dirt-consuming microorganisms in the
filter media and so reduce the filter performance.
Keep the unit straight when removing it from the pond, as the bottom section of the filter may contain dirt.
