INSTALLATION – SOLAR STORAGE TANK
Temperature Limiting Device
A temperature limiting device cannot be installed in circulated hot water flow and return pipe work. The
tempered water supplied from the temperature limiting device cannot be circulated.
Where a circulated hot water flow and return system is required in a building, a temperature limiting device
can only be installed on a dead leg, branching off the circulated hot water flow and return pipe.
If circulated tempered water were to be returned back to the booster water heater, then 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.
This condition 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 this condition, the operation and performance of the device cannot be
guaranteed.
REDUCING HEAT LOSSES
The cold water line to and the hot water line from the 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.
The full length of the solar hot and solar cold pipes between the solar storage tank and the solar collectors
"Warning: Plumber Be Aware"
MUST BE insulated. Refer to
on page 39.
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by the Rheem warranty when the total
dissolved solids (TDS) content in the water is less than 2500 mg/L and when the correct colour coded anode
is used. If an incorrect colour coded anode is used in the water heater, any resultant faults will not be covered
by the Rheem warranty. In addition, the use of an incorrect colour coded anode may shorten the life of the
water heater cylinder.
The correct colour coded anode for the water supply being used must be selected and fitted to the water heater
"Water Supplies"
for the Rheem warranty to apply to the water heater cylinder (refer to
on page 18 and the
Anode Selection table
on page 18). The black anode is typically fitted as standard.
If an incorrect anode is used, there is also the possibility the anode may become overactive and hydrogen gas
could accumulate in the top of the water heater during long periods of no use. In areas where this is likely to
"Caution"
occur, the installer should instruct the householder on how to dissipate the gas safely (refer to
on
page 19).
SADDLING - PIPE WORK
To prevent damage to the cylinder when attaching pipe clips or saddles to the solar storage tank jacket, we
recommend the use of self-drilling screws with a maximum length of 13 mm. Should pre drilling be required,
extreme caution must be observed when penetrating the jacket of the solar storage tank.
Note: If the cylinder or other components are damaged as a result of attaching pipe clips or saddles
to the jacket, any resultant faults will not be covered by the Rheem warranty.
