Maintenance and cleaning
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures:
Electrical units and installations with a rated voltage of U > 12 V AC or U >30 V DC located in the water:
Isolate the units and installations (switch off and disconnect from the power supply) before reaching into
the water.
Isolate the unit before starting any work.
Secure the unit to prevent unintentional switching on.
Cleaning the unit
Note!
Recommendation on regular cleaning:
Clean the pump as required but at least twice a year.
Do not use aggressive cleaning agents or chemical solutions as they could attack the housing or impair the function
of the unit.
Recommended cleaning agent for removing stubborn limescale deposits:
– Pump cleaning agent PumpClean from OASE.
– Vinegar- and chlorine-free household cleaning agent.
After cleaning, thoroughly rinse all parts in clean water.
How to proceed:
Open strainer casing and remove pump (B). Unscrew pump lid and remove impeller. Clean all components using clean
water and a brush.
After cleaning the pump, reassemble in the reverse order. Insert pump in the strainer casing. Regarding the 1500-2500
series of the filter pump, ensure correct seating of the rubber buffers used for the bearing of the pump. Route connec-
tion cable such that it cannot be pinched. Refit strainer lid and close.
