The lever on the temperature pressure relief valve and expansion control valve requires to be operated
every six (6) months to clear any deposits and to ensure the valve and its drain line are not blocked.

The 52H closed circuit system has freeze protection. The amount of closed circuit concentrate supplied
with this water heater provides protection in frost prone areas to a certain temperature. The
page
65 lists the percentage of Coolblend concentrate fluid in the closed circuit of each system and the
recommended minimum ambient temperature for the system, for the number of bottles supplied with each

system. Refer to
•
The 52L open circuit system does not have freeze protection. The system is not suitable for installation in
areas subject to frost or freeze conditions.
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 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,
▪
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 95°C during its operation.
•
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 850 kPa and an
expansion control valve with a pressure rating of 700 kPa.
The maximum mains water supply pressure for the water heater is 680 kPa when an expansion control valve
is installed. If the mains supply pressure in your area exceeds this value, a pressure limiting valve must be
installed.
The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
