Mains Pressure Operation
This water heater is designed to operate at mains pressure by connecting
directly to the mains water supply. If the mains supply pressure in your area
exceeds that shown in ‘Mains Water Supply’ on page 23, a pressure
limiting valve must be fitted. The supply pressure should be greater than
350 kPa for true mains pressure operation to be achieved.
Hot Water Temperature
This water heater features a user adjustable thermostat located behind the
front access panel which controls the temperature of the stored water in
the storage cylinder. The thermostat is adjustable between 30 ~ 70°C
(factory setting approximately 60°C). Refer to ‘Temperature Adjustment’ on
page 8.
To meet the requirements of the National Plumbing Standard, the
temperature of the stored water must not be below 60°C.
Note: AS 3498 requires that a water heater provides the means to inhibit
the growth of legionella bacteria in stored potable water. This water heater
can satisfy this AS 3498 requirement provided it is operating and the
thermostat setting is set at 60°C or higher.
High Hot Water Temperature Increases the Risk of Scald Injury
Warning: This water heater can deliver water at temperatures which
can cause scalding. Always 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 a scald injury. Aquamax recommends
monthly temperature checks to ensure the appropriate temperature is
maintained within the hot water heater.
Aquamax recommends, and it may also be required by regulations, that a
secondary device such as an approved temperature limiting device or anti-
scald water shut off valve be fitted into the hot water pipe work to the
bathroom(s) and ensuite(s) if persons living in the house require additional
safety protection from potential scalding. This will keep the hot water supply
temperature to the bathroom(s) and ensuite(s) below 50°C which will
reduce the risk of scald injury whilst still allowing hotter water (60°C+) to the
kitchen and laundry.
For new hot water installations, all sanitary outlet fixtures used primarily for
personal hygiene purpose must deliver hot water not exceeding 50°C. This
temperature limit is not mandatory for kitchen sinks and laundry tubs and
the preferable temperature setting for these outlets should be 60°C.
