Electric installation
All electric installations must be made by a qualified electrician according to the accompanied heater instructions.
The heater must be installed with a main supply on-off switch. We also recommend to install an earth fault relay.
Connect the heater as shown in the wiring diagram, see following pages 4 and 5. 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 contactor must be
guided over the motor protection of the pump.
Do not connect the heater to an improper source of electricity.
Contact the local utility to obtain information about the correct power supply.
Voltage applied to the heater should not vary more than +5% to -10% to the model and rating plate specification.
