Pipe installation
Connect the heater into the pool system as shown in the diagram below. The outlet must not be connected to any tap or fitting
other than those specified.
The heater is equipped with G2¾” unions to be glued on PVC pipes with outer dimension Ø63 mm.
Note! Do not install a gate valve between the heater and the swimming pool (install a check valve instead).
Dosage of chlorine, acid or similar, must always be done
after
the heater to avoid corrosion.
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.
