INSTALLATION NOTES
This water heater must be installed:
•
by a qualified person,
•
in accordance with the installation instructions,
•
in compliance with the Plumbing Code of Australia (PCA) and Plumbing Standard AS/NZS 3500.4,
▪
This water heater is designed for either indoor or outdoor installation.
▪
This water heater is intended to be permanently connected to the water mains and not connected by
a hose-set. A braided flexible hose or semi-flexible connector may be used for connection to the water
heater, where permitted by AS/NZS 3500.4.
•
in compliance with the Australian / New Zealand Wiring Rules AS/NZS 3000,
▪
An isolation switch must be installed at the switchboard in the electrical circuit to the water heater in
accordance with the Wiring Rules, so the water heater can be switched off. Refer to
on page 34.
▪
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 80°C on occasion.
•
in compliance with all local codes and regulatory authority requirements.
Installation and commissioning requirements and details for the installing plumber and licensed electrical
worker are contained on
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.
