STORAGE TANK APPLICATION
This storage tank is designed for the purpose of storing water treated with a corrosion inhibitor and is not
designed for use with potable water. Its use in an application other than this may shorten its life.
MODEL TYPE
®
The Rheem
Commercial hot water storage tank you have chosen can be installed indoor or outdoor,
depending on the type of insulation selected. Aluminium clad insulation is suitable for indoor or outdoor
installation. PVC outer cover is suitable for indoor installation only (not available in Australia or New Zealand).
Heat transfer fluid is stored in a carbon steel cylinder and heated by an external primary heating source, or
via the two flanges that allow the fitment of auxiliary heating such as heat exchange coils (not supplied) or an
electric heating unit bundle. The temperature is controlled by the thermostat(s) on the heating source.
Automatic safety controls must be fitted to the primary heating source to provide safe and efficient operation.
CLOSED CIRCUIT
The storage tank is designed to operate at low pressure in a closed loop circuit, with the use of a heat
transfer fluid. The supply pressure must not exceed that
HOW HOT SHOULD THE WATER BE?
The storage tank is designed for a maximum allowable water
temperature of 90°C, unless operated as a permanently vented
cylinder. Refer to the installation instructions supplied with the
primary heating source plant for further information on water
temperatures.
Note: AS 3498 requires that a water heater provides the means to
inhibit the growth of Legionella bacteria in potable water.
This storage tank is not designed to contain potable water. The
requirement to provide the means to inhibit the growth of Legionella
bacteria must be fulfilled by the secondary heating source. Refer to
installation instructions of the secondary heating source.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY.
This storage tank 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 also be required by regulations that an approved temperature limiting device be
fitted into the hot water pipe work to the bathing and public areas when this storage tank is installed. This will
keep the water temperature below 50°C or the maximum permitted by AS/NZS 3500.4 to these areas. The
risk of scald injury will be reduced and still allow hotter water to the kitchen, laundry and other areas requiring
sanitising temperatures.
TEMPERATURE ADJUSTMENT
We advise the thermostats of the primary heating plant are adjusted to the lowest temperature setting that
meets your needs, especially if there are young children or elderly people in the premises. Refer to
Water Increases the Risk of Scald Injury"
