Maintenance
When back-washing and cleaning the filter, the power to the heater must be turned off.
The heater must be drained before it is exposed to sub-zero temperatures or if the pool system is closed for a longer time.

The electric installation must be done by a licenced electrician.
The heater shall be connected over one or two contactors, depending on type of heater, see picture wiring diagram below.
Connect earth to heating element according to picture 2.
The heater shall be installed in such way that it cannot be activated if the circulation pump is not working (sufficient flow),
i.e. the power supply to the heater contactor must be guided over the pump contactor.

Start the pump of the pool water circulation.
2.
Check that the water circulation is normal before the heater is turned on.
3.
Test the heater by turning the thermostat knob back and forth and check that the contactor of the thermostat turns on and off.
Check any flow switch or pressure switch by turning off the flow through the heater with a gate valve and control that the
contactor is beeing deenergized.
4. Set desired pool water temperature by turning the thermostat knob.
5.
The heater will now heat the pool water to desired temperature.
