HOT WATER DELIVERY
This water heater can deliver water at temperatures which can cause scalding. This water heater has
both a hot water outlet connection and a tempered water outlet connection. The temperature of the
water from the hot water outlet can be up to 75°C and the water from the tempered water outlet can be
up to 50°C.
The delivery water temperature requirements of AS/NZS 3500.4 allow water in excess of 50°C to be
delivered to fixtures not used primarily for ablution purposes, such as in a kitchen or laundry. These
types of fixtures can be supplied from the hot water outlet of this water heater.
It is necessary and we recommend that a tempered water line, from the outlet connection of the
temperature limiting device, be fitted between the water heater and the hot water outlets in any ablution
area such as a bathroom or ensuite, to reduce the risk of scalding. The installing plumber may have a
legal obligation to ensure the installation of this water heater meets the delivery water temperature
requirements of AS/NZS 3500.4 so that scalding water temperatures are not delivered to a bathroom,
ensuite or other ablution area.
The tempered water outlet from this water heater will not deliver temperatures exceeding 50

The tempered water outlet from this water heater will not deliver temperatures exceeding 50
°C, in
accordance with AS 4032.2 There is no statutory requirement to fit a supplementary temperature
limiting device if this water heater is installed in other than an early childhood centre, school, nursing
home or a facility for young, aged, sick or disabled people.
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.
