Storage/overwintering
The unit is protected from freezing temperatures (e.g. stored in a garage or other enclosure)
The unit can be operated as long as the water temperature does not drop below 39 °F (+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. Take the following measures to reduce the cooling effect on the water during cir-
culation by the filter system:
• Position the pump closer 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 freezing temperatures (e.g. outdoor installation)
Shut down the unit at water temperatures below 46° F (+8 °C) or, at the latest, when freezing
temperatures 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.
