INSTALLATION
24
Where a temperature limiting device is installed adjacent to the water heater, the
cold water line to the temperature limiting device can be branched off the cold
water line either before or after the isolation valve, pressure limiting valve and
non-return valve to the water heater. If an expansion control valve is required, it
must always be installed after the non-return valve and be the last valve prior to
the water heater.
If a pressure limiting valve is installed on the cold water line to the water heater
and the cold water line to a temperature limiting device branches off before this
valve or from another cold water line in the premises, then a pressure limiting
valve of an equal pressure setting may be required prior to the temperature
limiting device.

Two Temperature Zones Using a Temperature Limiting Device
A RheemPlus water heater will
not deliver temperatures
exceeding 50°C, in accordance
with AS 3498. There is no need to
fit a temperature limiting device to
satisfy the requirements of
AS/NZS 3500.4, if a RheemPlus
water heater is installed in an
application where 50°C is the
maximum permissible hot water
temperature at the outlet of a
sanitary fixture used primarily for
personal hygiene purposes.
