9 Storage/overwintering
The unit is protected from frost:
The unit can be operated as long as the water temperature does not go below +4 °C.
► Set the interval for time-dependent cleaning to 20 minutes to avoid damage to the rinsing device in
the event of frost.
► Install the control system in such a way that it is protected. The minimum operating temperature of the
control system is -10 °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.
