•
in compliance with the Australian / New Zealand Wiring Rules AS/NZS 3000,
▪ Isolation switches must be installed in the electrical circuit to the water
heater in accordance with the Wiring Rules, so the water heater can be
switched off.
▪ The power supply wires are to be directly connected to the terminal block
and earth tab connection, with no excess wire loops inside the front cover.
The temperature rating of the power supply wires insulation must suit this
application, or the wiring protected by insulating sleeving with an
appropriate temperature rating if it can make contact with the internal
storage cylinder. The temperature of the internal storage cylinder can
reach 70°C under normal operation.

Mains pressure water supply
The water heater is designed to operate at mains pressure by connecting directly
to the mains water supply.
The water heater is supplied with a temperature pressure relief valve with a
pressure rating of 1000 kPa. If an expansion control valve has been installed on
the cold water line to the water heater, this should have a pressure rating of
850 kPa.
The maximum mains water supply pressure for the water heater is 800 kPa if an
expansion control valve is not installed, or 680 kPa if an expansion control valve
is installed. If the mains supply pressure in your area exceeds these values, a
pressure limiting valve must be installed.
The supply pressure should be greater than 350 kPa for true mains pressure
operation to be achieved.
