Connections - Electrical - Rheem 812 Series Owner's Manual And Installation Instructions

All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the
Wiring Rules AS/NZS 3000 and all local codes and regulatory authority requirements.
Warning: Temperature controllers must not be fitted to this water heater (874 series) if it is installed as an
in-series gas booster with a solar water heater system because water at a temperature much higher than the
controller setting can be delivered. If a solar water heater is installed to an existing water heater installation,
then all controllers must be disconnected and removed.
The water heater is supplied with a 1.8 metre lead and plug and requires a weatherproof 240 V AC 50 Hz
general purpose outlet (GPO) to be located within 1.2 metres of the installation. The GPO must be clear of the
flue exhaust, draining water, gas supply pipe and water connections.
