HOW HOT SHOULD THE WATER BE?
The water heater features an adjustable
electronic thermostat, which allows the most
suitable temperature for the application to be
chosen.
To meet the requirements of the National
Plumbing Standard the temperature of the
stored water for hot water applications must
not be below 60°C.
The maximum user adjustable set point
temperature for DHW models ('W' suffix) is
o
71
C. For temperatures above 71
hydronic model ('H' suffix) will be required.
Hydronic models ('H' suffix) are able to be
o
user set to 82
C.
HOTTER WATER INCREASES THE RISK
OF SCALD INJURY
This water heater can deliver water at
temperatures which can cause scalding.
Check the water temperature before use,
such as when entering a shower or filling a
bath or basin, to ensure it is suitable for the
application and will not cause scald injury.
We recommend and it may be required by
regulations that an approved temperature
limiting device be fitted into the hot water
piping to the bathroom and ensuite when this
water heater is installed. This will keep the
water temperature below 50°C at the
bathroom and ensuite. The risk of scald injury
will be reduced and still allow hotter water to
the kitchen and laundry.
TEMPERATURE ADJUSTMENT
The system temperature will have been set by the installer to suit the application, adjustment should
not be required. Only an authorised person can make adjustments to the MVB.
DOES THE WATER CHEMISTRY AFFECT THE WATER HEATER?
The water heater is suitable for most public water supplies, however some water chemistries may have
detrimental effects on the water heater, its components and fittings. Refer to "Water Supplies" on page
18.
If you are in a known harsh water area or you are not sure of your water chemistry, have your water
checked against the conditions described on page 18.
HOW LONG WILL THE WATER HEATER LAST?
The water heater is supported by a manufacturer's warranty (refer to "Warranty" on page 4). There are
a number of factors that will affect the length of service the water heater will provide. These include but
are not limited to the water chemistry, the water pressure, the water temperature (inlet and outlet) and
the water usage pattern. Refer to "Precautions" on page 12.
