SAFETY, WARNINGS, INSTALLATION NOTES
10
• The water heater will operate until a water temperature of up to 65°C is
reached, depending upon the thermostat setting.
Refer to “How Hot Should The Water Be?” on page 13 and “Temperature
Adjustment” on page 14.
• The lever on the temperature pressure relief valve and expansion control
valve (if fitted) requires to be operated every six (6) months to clear any
deposits and to ensure the valve and its drain line are not blocked.
Refer to “Relief Valves” on page 10 and “Minor Maintenance Every Six
Months” on page 17.

RELIEF VALVES
Temperature Pressure Relief Valve
This water heater incorporates a temperature
pressure relief valve located near the top of the
water heater. This valve is essential for the
water heater’s safe operation.
It is possible for the valve to discharge a
quantity of water through the drain line during
each heating period. This quantity should be
equal to approximately 1/50 of the hot water
used, as water expands by this volume when
heated.
Expansion Control Valve
In many areas, including South Australia,
Western Australia, New Zealand and scaling
water areas, it is mandatory an expansion
control valve is fitted to the cold water line to
the water heater.
The expansion control valve will discharge the quantity of water from its drain
line during the heating period instead of the temperature pressure relief valve as
it has a lower pressure rating.
