Maintenance and cleaning

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.

WARNING

!

This pump uses a very strong magnet to achieve superior performance. When removing the impeller assembly there
will be considerable magnetic force resisting the extraction of the impeller assembly. This is normal. Likewise when
replacing the impeller assembly there will be a strong magnetic force pulling the assembly into the pump to potentially
cause injury to ngers and in rare cases damaging the ceramic shaft or rear bearing. Use thick gloves when replacing
the impeller assembly.

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.

● 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 warm water.

Cleaning the pump

1.

1. Disconnect the pump from the power source.

○ Disconnect the tubing.

2. Remove the screen and disassemble the impeller

housing to expose the impeller assembly.

3. For Pond Pump 280 / 420, remove the impeller

assembly by gently pulling on the impeller blades.
For Pond Pump 575 remove the impeller assembly by
