Storage/winter protection
The unit is protected from frost (e.g. stored in a garage or other enclosure)
The unit can be operated as long as the water temperature does not go below +4 °C.
The deeper areas of the pond have a water temperature of approx. +4 °C in winter and are essen-
tial for the fish. By taking the following measures it is possible to reduce the cooling effect on
the water of the circulation by the filter system:
 Position the pump nearer to the surface of the water so that only colder water closer to the
surface of the pond enters the pump.
 Insulate the return pipes from the filter system into the pond.
 Do not allow water to flow into the pond via a water course.
The unit is not protected from frost (e.g. outdoor installation)
Shut down the unit at water temperatures below +8 °C or at the latest when freezing tempera-
tures are expected.
 Drain the water remaining in the unit, in the hoses, pipes and connections as much as possi-
ble.
 Open all slide valves to prevent water from pooling.
 Cover the container to prevent rain water from entering.
 Protect any lines and slide valves from which you cannot drain the water against freezing.
