ABOUT YOUR WATER HEATER
MODEL TYPE
Congratulations for choosing a Rheem
® water heater. The model you have
chosen will be either a Rheemglas ® , Optima™ or RheemPlus™ model. The
Optima model has a temperature adjusting knob on the lower front of the water
heater. Rheemglas and Optima models are available with either a single
heating unit or with twin heating units and the RheemPlus models are available
with a single heating unit only (refer to
“Single Element Model” on page 8 and
“Twin Element Model” on page 9).
HOW HOT SHOULD THE WATER BE?
The water heater features an
adjustable thermostat, which allows
you to choose the most suitable
temperature for your hot water needs.
Refer to
“Temperature Adjustment” on
page 5.

A RheemPlus water heater is
temperature limited to deliver water not
exceeding 50
°C.
To meet the requirements of the
National Plumbing Standard the
temperature of the stored water must
not be below 60

If this water heater is installed as part
of a solar water heating system, we
recommend the thermostat is set at
60
°C to maximise solar contribution.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater 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
bathroom and ensuite when a Rheemglas or Optima water heater is installed.
This will keep the water temperature below 50
°C at the bathroom and ensuite.
The risk of scald injury will be reduced and still allow hotter water to the kitchen
and laundry.
