Storage/overwintering
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 drop below 39 °F (+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 14 °F (-10 °C).
The deeper areas of the pond have a water temperature of approx. 39 °F (+4 °C) in winter and are vital
for fish. Take the following measures to reduce the cooling effect on the water during circulation 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 stream.
The unit is not protected from frost (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 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 container so that no rain water can enter.
► Protect pipes and slide valves that are in contact with water from frost.
