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

•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 to arrange for an inspection.
•This water heater uses 220 V –240 V a.c. power for the electrically operated
components. The removal of the front cover(s) will expose 220 V –240 V a.c.
wiring. It must only be removed by a qualified person.
•This water heater is supplied with a thermostat, an over-temperature cut-out
and 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 Everhot warranty may not cover faults if relief valves or other safety
devices are tampered with or if the installation is not in accordance with
these instructions.
•DANGER: The operation of the over-temperature cut-out on a thermostat
indicates a possibly dangerous situation. If the over-temperature cut-out
operates, it must not be reset and the water heater must be serviced by a
qualified person.
•The water heater will operate until a water temperature of 60°C to 75°C for
250 and 315 models or 60°C to 80°C for 050 models is reached, depending
upon the thermostat setting.
Refer to “How Hot Should The Water Be?” on page 12 and “Temperature
Adjustment” on page 13.
•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 9 and “Minor Maintenance Every Six
Months” on page 17.

•Servicing of a water heater must only be carried out by qualified personnel.
Phone Rheem Service or their nearest Accredited Service Agent.
•Only a person qualified to install or service a water heater should drain the
water heater, if this is required.
•Do not modify this water heater.
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 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 “Temperature Pressure
Relief Valve or Expansion Control Valve
Running” on page 23.
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.

SAFETY, WARNINGS, INSTALLATION NOTES

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. It is very important the lever is raised
and lowered gently. Refer to “Minor Maintenance Every Six Months” on
page 17.
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 water heater 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 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 18.
