INSTALLATION – SOLAR STORAGE TANK
34
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
MUST BE
insulated. Refer to
on page 44.
BOOSTER HEATING UNIT
The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy
or rainy weather, or during the colder months. Refer to
on page 49 for electrical
connection requirements and control options of the booster heating unit.
If this water heater is installed with an in-series booster, then the electric booster heating unit in the solar
storage tank will not need to be connected to a power supply.
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by the Solahart 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 Solahart 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
for the Solahart warranty to apply to the water heater cylinder (refer to
on page 20 and the
on page 20). 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
occur, the installer should instruct the householder on how to dissipate the gas safely (refer to
page 21).
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 is damaged as a result of attaching pipe clips or saddles to the jacket, any resultant
faults will not be covered by the Solahart warranty.
