ABOUT YOUR WATER HEATER
WATER HEATER APPLICATION
This water heater is designed for the purpose of heating potable water by
simultaneously reducing building chilling load. Its use in an application other than
this may shorten its life.
MODEL TYPE
Congratulations for choosing a Rheem
®
commercial water to water (W2W) heat
pump water heater. The Rheem W2W
heat pump water heater is designed for
outdoor or indoor installation.
HOW HOT SHOULD THE WATER BE?
The heat pump (compressor, evaporator
and condenser) will operate until a water
temperature of up to 65

C is reached.
To meet the requirements of the National
Plumbing Standard (AS/NZS3500.4) the
temperature of the stored water must not
be below 60

C.
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 this water heater is installed. This will keep the water
temperature below 50

C (55

C in NZ) at the bathroom and ensuite. The risk of
scald injury will be reduced and still allow hotter water to the kitchen and laundry.
