Storage/Over-wintering

The unit is protected from frost:
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 essential 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:
Take the unit out of operation at water temperatures below +8° C or, at the latest, when freezing temperatures
are to be expected.
• Drain the unit as far as possible, clean thoroughly and check for damage.
• Empty all hoses, pipes and connections as far as possible.
• Leave the slide valves open.
• Cover the filter container to prevent the penetration of rain water.
• Protect pipes and slide valves that are in contact with water from frost.
