SAFETY, WARNINGS, INSTALLATION NOTES
It is important you read the following safety and warnings information.
SAFETY AND WARNINGS
•This water heater is only intended to be operated by persons who have the
experience or the knowledge and the capabilities to do so.
•This water heater is not intended to be operated by persons with reduced
physical, sensory or mental capabilities i.e. the infirm, or by children.
Children should be supervised to ensure they do not interfere with the water
heater.
•If the electrical conduit to the water heater is damaged, it must be replaced
by a qualified person in order to avoid a hazard. Phone Rheem Service or
their nearest Accredited Service Agent / Centre to arrange for an inspection.
•This water heater uses 400V / 230 V AC electrical power for operation of
the control systems and other electrically operated components. The
removal of the access cover(s) will expose 400V / 230 V wiring. They must
only be removed by a qualified person.
•This water heater is supplied with built in Rheem IQ Controller which
controls low and high pressure switches, low temperature cut off,
temperature safety switch and flow switch.
Additionally, the compressor is fitted with thermal overload protection,
the condenser heat exchanger is fitted with a pressure relief valve, the
heat pump is supplied with a built in ambient temperature sensor and
the storage tanks are supplied with a combination temperature pressure
relief valve. These devices must not be tampered with or removed. The
water heater must not be operated unless each of these devices is fitted
and is in working order.
•The water heater will operate until a water temperature of 60°C to 65°C is
reached, depending upon the setting of the controller.
Refer to “How Hot Should The Water Be?” on page 12.
•The lever on the temperature pressure relief valve on the storage tank 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 9 and “Minor Maintenance Every Six
Months” on page 19.

•For continued safety of this water heater it must be installed, operated and
maintained in accordance with the Owner’s Guide and Installation
Instructions.
•Servicing of a water heater must only be carried out by qualified personnel.
Phone Rheem Service or their nearest Accredited Service Agent / Centre.
•Only a person qualified to install or service a water heater can drain the
water heater, if this is required.
•Do not modify this water heater.
RELIEF VALVES
Temperature Pressure Relief Valve
The storage tank connected to this water heater incorporates a temperature
pressure relief valve located near the top of the storage tank. 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.
Valve Operation
Continuous leakage of water from either valve and its drain line may indicate a
problem with the water heater. Refer to “Minor Maintenance Every Six Months”
on page 20.
Warning: Never block the outlet of either valve or their drain lines for any
reason. A relief valve drain must be left open to atmosphere, and be installed in
a continuously downward direction.
In locations where water pipes are prone to freezing, the relief valve drain line
must be insulated and not exceed 300 mm in length before discharging into a
tundish through an air gap.
Operate the easing lever on the temperature pressure relief valve and expansion
control valve once every six (6) months to clear any deposits and ensure the
valve and its drain line are not blocked.

10
It is very important the lever is raised and lowered gently. Refer to “Minor
Maintenance Every Six Months” on page 19.
Warning: Water discharged from the temperature pressure relief valve drain
line will be hot. Exercise care to avoid any splashing of water by standing clear
of the drain line’s point of discharge when operating either valve’s easing lever.
DANGER: Failure to operate the easing lever on the relief valve once every
six (6) months may result in the storage tank cylinder failing, or under certain
circumstances, exploding.
If water does not flow freely from the drain line when the lever is lifted, then the
water heater must be checked. Phone Rheem Service or their nearest Accredited
Service Agent / Centre to arrange for an inspection.
The temperature pressure relief valve should be replaced at intervals not
exceeding five (5) years and the expansion control valve should be checked for
performance or replaced at intervals not exceeding five (5) years. The checking
of the valves performance or replacement should occur more frequently in areas
where there is a high incidence of water deposits. Refer to “Water Supplies” on
page 21.
