Electric requirements

CAUTION:
Do not incorrectly connect electrical
connections. 230-240V AC must be applied
to L and N wires as shown in Fig. 11. Failure
to do so will VOID the warranty and can result
in irreversible damage to the appliance.
Power requirements
Check the markings on the rating plate of the water heater to be
certain the available power supply corresponds to the water
heater requirements.
This water heater must be directly connected to a 230V-240V
AC, 50Hz mains power supply. When connected off grid,
please make sure a 230V-240V AC 50Hz true sine wave power
supply is available.
Do not connect this unit to inverters providing square sine
waves.
Electrical connections

All electrical work and fixed wiring must be
carried out by a qualified professional and in
accordance with the Wiring Rules AS/NZS
3000 and local authority requirements.
The water heater must be installed on its own circuit with a
