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 your Rheem Service 
Centre to arrange for an inspection. 
•This water heater uses 230 V a.c. power for the electrically operated 
components. The removal of the front cover will expose 230 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 Rheem 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 70°C 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 16. 
•For continued safety of this water heater it must be installed, operated and 
maintained  in  accordance  with  the  Owner’s  Guide  and  Installation 
Instructions. 

SAFETY, WARNINGS, INSTALLATION NOTES

•Servicing of a water heater must only be carried out by qualified personnel.

Phone your Rheem Service 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

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

It is mandatory an expansion control valve is fitted to the cold water line to the

water heater to comply with Clause G12 of the New Zealand Building Code,

unless the water heater is installed as a push through installation.

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 22.

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 16.

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 your Rheem Service 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 17.
