CONNECTIONS – ELECTRICAL
The electrical installation must comply with AS/NZS 3000, AS/NZS 5601 or 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,
5.2.11 or 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.
The power supply for the pump and the water heater must be supplied from the same circuit and isolating switch;
alternatively the circulator power supply may be switched by a relay as depicted in the following wiring diagrams.
