ABOUT YOUR WATER HEATER
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 bathroom
and ensuite when a Rheem 312 series water heater is installed. This will keep
the water temperature below 55°C at the bathroom and ensuite. The risk of scald
injury will be reduced and still allow hotter water to the kitchen and laundry.
THERMOSTAT
The thermostat automatically controls the electricity supply to the heating unit so
a constant temperature is maintained. The thermostat and its protective over
temperature cut out is mounted inside the front cover of the water heater. There
is no need to switch the water heater off when it is not in use, except when you
are on an extended holiday. The thermostat is fully automatic and power is only
used when heating is required.
TEMPERATURE ADJUSTMENT
A Rheem 312025 model water heater features a tradesperson adjustable
thermostat. This requires a licensed electrical worker to make any temperature
adjustments. The thermostat has a maximum temperature setting of 70°C. The
minimum temperature setting is 60°C.
We advise you to have a licensed electrical worker adjust the thermostat to the
lowest temperature setting that meets your needs, especially if there are young
"Hotter Water Increases The
children or elderly people in your home. Refer to
Risk of Scald Injury"
on page 12.
PRECAUTIONS
Where damage to property can occur in the event of the water heater leaking,
the water heater must be installed in a safe tray. Construction, installation and
draining of a safe tray must comply with AS/NZS 3500.4 and all local codes and
regulatory authority requirements. The safe tray must also meet the
requirements of Clause G12 of the New Zealand Building Code. AS/NZS 3500.4
and the NZBC also have particular requirements when a safe tray must be
installed.
The water heater must be maintained in accordance with the Owner's Guide and
"Maintenance Requirements"
Installation Instructions. Refer to
on page 15 and
"Anode Inspection and Replacement"
to
on page 18.
If this water heater is to be used where an uninterrupted hot water supply is
necessary for your application or business you should ensure that you have
back-up redundancy within the hot water system design. This should ensure the
continuity of hot water supply in the event that this water heater were to become
inoperable for any reason. We recommend you seek advice from a plumber or
specifier about your needs and building back-up redundancy into your hot water
supply system.
