Attention! Dangerous electrical voltage.
Possible consequences: Death or serious injuries.
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
● Regular cleaning of the pump may be necessary depending upon the
environment in which it is operated. Clean the pump when it is visibly
soiled or when a drop in performance is detected. Clean the unit with
warm water using a soft brush.

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 warm water.
