– ELECTRICAL
The electrical installation must comply with AS/NZS 3000, AS 3814, AS/NZS 5601.1 and any local
requirements.
This water heater must be hard wired to a 240V AC 50 Hz M.E.N. (multiple earthed neutral) mains
power supply with an all pole isolating switch installed adjacent to and accessible from the water heater
(refer to AS/NZS 5601.1:2010 clause 6.2.8). A suitable warning label must be affixed to the water heater
if there are additional control circuits not isolated by this switch. This label should direct the service
person to the isolation switch for that circuit.
Do not locate conduits across the doors, control panel or the top of the water heater.
Where a conduit is to be mounted on the water heater cabinet there must be a 10 mm air gap between
the conduit and the water heater cabinet to prevent overheating of the wiring.
