Hints for maintenance
The pond motor pump is a maintenance-free and a practice-proven quality product that was subjected
to rigorous final inspections. For a long working life and continuous operation, we recommend regular
checking and proper care.
Maintenance and cleaning
Overload protection:
The pump has an integrated overheat protection. After the pump is stopped it must cool down for a while
due to the overheat control device, before it runs again. In case it does not run again by itself, the
following checks shall be conducted:
Has the pump cooled down sufficiently due to the overheat protection after being stopped?
Is the water supply sufficient?
>
Improve the water supply!
Is the filter clogged?
>
If necessary, rinse the filter!
Is there dirt in the pump housing?
>
Perform cleaning!
Is the hose or the pipe clogged?
>
Clear the hose/pipe!
Is the hose broken, too long?
>
Check, replace, shorten!
