Note:
Installation
The Pump has to be installed under water. Make sure that moisture or water never reaches the
mains connection.
The pump is to be installed as follows: in a fixed position with fixed or flexible hose.
Take care, that there are no bubbles in the hoses.
Immerse the pump into the pond water (min 20cm), so that it is filled with water.
To avoid the premature clogging of the filter, position the pump above the pond sludge.
Install the supplied filter sponge to keep the pump inlet free.
The pump is started by plugging in the mains plug.

Warranty Information
Not covered by warranty:

Hints for maintenance!
The pond motor pump is a maintenance-free and a practice-proven quality product that was sub-
jected to rigorous final inspections. For a long working life and continuous operation we recom-
mend regular checking and proper care.
Maintenance and Cleaning
Overload protection:
The pump has an integrated overheat protection. After the pump is stopped it has to 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:
Could the pump cool 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!
