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.
If necessary, clean the unit with clear water using a soft brush.
•
Never use aggressive cleaning agents or chemical solutions. These could attack the housing surface or impair the
function.
•
In the event of stubborn furring (calcium deposits), a common household cleaner free from vinegar and chlorine can
be used. Subsequently, clean the pump thoroughly using clear water.
Cleaning the unit
C
Open strainer casing and remove pump. 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. Route connection cable
such that it cannot be pinched. Refit strainer lid and close.
Storage/Over-wintering
Remove the unit at temperatures below zero degrees centigrade. Thoroughly clean and check the unit for damage.
Store the unit immersed in water or filled with water in a frost-free place. Do not flood the power plug!
