Electrical supply and connections

The electrical connection must be carried out by a qualified person in accordance with NZ Electrical
Regulations. The water heater must have the heating element connected to an independent, fused,
AC 230 V 50 Hz power supply with an isolating switch installed at the switch board.
• The water heater must be filled with water prior to connection to the power supply
• Disconnect all power prior to installation and commissioning
• Household wiring to the heater must be capable of withstanding the appliance load
Electrical access is via a hole in the element cover for mounting with an approved electrical conduit
gland. For entry to the element cover remove the two fixing screws.
Connect all PHASE and NEUTRAL wires in accordance with the wiring diagram. Inspect and ensure all
wiring links are secure prior to fixing the access cover and turning the power on.
To ensure the over-temperature and energy cutout is set press the 'reset' button on the thermostat (not
applicable for wetback tanks).
