HOT WATER DELIVERY
This water heater can deliver water at temperatures which can cause scalding. This water heater has both a
tempered water outlet connection and a hot water outlet connection.
Tempered Water Outlet
The tempering valve on this water heater is WaterMark Certified to AS 4032.2 and is factory set to deliver
water not exceeding 50°C from the tempered outlet. The risk of scald injury will be reduced. There is no need
to fit a temperature limiting device to satisfy the requirements of the Plumbing Code of Australia, to the pipe
work from the tempered water outlet and serving 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, such as in a
bathroom or ensuite.
Hot Water Outlet
This water heater can deliver hot water at a temperature up to 75°C from the hot water outlet, sufficiently hot
to cause severe scalding. Water at this temperature may be plumbed to fixtures where water hotter than 50°C
is allowed, such as the kitchen and laundry.
The installing plumber may have a legal obligation to ensure the installation of this water heater meets the
delivery water temperature requirements of the Plumbing Code of Australia so that scalding water
temperatures are not delivered to a bathroom, ensuite or other ablution or public area.
It is necessary and we recommend that a temperature limiting device be fitted between the hot water outlet of
the water heater and the hot water outlets in any ablution and public areas such as a bathroom, ensuite or
public amenities, to reduce the risk of scalding.
The temperature limiting device must be of a type suitable for use with both a continuous flow water heater
and a solar water heater. Refer to the manufacturer’s specifications of the temperature limiting device.
Where another 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. The hot
water line to this temperature limiting device must be taken from the hot water outlet connection of the water
heater and not from the tempered water outlet connection of 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
another 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.
