Operation
After having read the installation instructions carefully, you can start the new pump if you note the fol-
lowing aspects:
1. Check if the pressure pipes have been installed properly.
2. Make sure that the electrical connection is 230=V~50=Hz.
3. Check if the socket works properly.
4. Make sure that moisture or water never reaches the mains connection.
5. Install the pump beneath the water surface.
6. Avoid that the pump runs dry.
7. Do not use the pump without filter basket, that protects it from large impurities that can block the
pump.
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 on a weekly basis.
Overload protection
The pump has an integrated overheat protection. After the pump has been stopped by the overheat
control device, it must cool down for a while before being able to run again. In case it does not run
again by itself, the following checks shall be made:
Could the pump cool down sufficiently after having been stopped by the overheat protection ?
Is the water supply sufficient? > Improve the water supply!
Is the filter contaminated? > Clean it (see below)!
Is the hose or the pipe blocked? > Clean them!
Is the hose broken, too long? > Check, replace, shorten!
