If circulated tempered water were to be returned back to the water heater,
depending on the location of the return line connection on the water supply line
to the water heater, then either:
water will be supplied to the cold water inlet of the temperature limiting
device at a temperature exceeding the maximum recommended water
supply temperature, or
when the hot taps are closed no water will be supplied to the cold water inlet
of the temperature limiting device whilst hot water will continue to be supplied
to the hot water inlet of the temperature limiting device.
These conditions may result in either water at a temperature exceeding the
requirements of AS/NZS 3500.4 being delivered to the hot water outlets in the
ablution areas, or the device closing completely and not delivering water at all,
or the device failing. Under either condition, the operation and performance of
the device cannot be guaranteed.
INSULATION
To minimise heat loss and provide protection from freezing, the cold water line
to and the hot water line from the heat pump water heater must be insulated in
accordance with the requirements of AS/NZS 3500.4. The insulation must be
weatherproof and UV resistant if exposed.
SADDLING - PIPE WORK
To prevent damage to the heat pump and storage tanks when attaching pipe
clips or saddles to the water heater jacket, we recommend the use of self-drilling
screws with a maximum length of 12
extreme caution must be observed when penetrating the jacket of the water
heater.
Avoid drilling or saddling in the vicinity of the refrigerant or plumbing
circuits. These circuits are in close proximity to the jacket and rupturing of
the circuit may occur.
Note: If the heat pump is damaged as a result of attaching pipe clips or
saddling to the jacket, any resultant faults will not be covered by the Rheem
warranty.
