INSTALLATION – SOLAR STORAGE TANK

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 pipe work between the solar storage tank and the solar collectors must be fully insulated with
closed cell polymer insulation or similar (minimum thickness 13 mm). Thicker insulation may be
required to comply with the requirements of AS/NZS 3500.4. The insulation must be weatherproof and
UV resistant if exposed. The insulation must be fitted up to the connections on both the solar storage
tank and the solar collectors.
ANODE TYPES
The correct anode type for the water supply being used must be fitted in the water heater (refer to
“Water Supplies” on page 36). The black anode is fitted as standard.

SADDLING - PIPE WORK
To prevent damage to the cylinder 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 mm. Should pre drilling be
required, extreme caution must be observed when penetrating the jacket of the water heater.
Note: Damage to the cylinder as a result of saddling to the jacket will void the warranty.
BOOSTER HEATING UNIT
The booster heating unit provides hot water during periods of low solar gain. This can be connected to
either an Off-Peak (overnight), Extended Off-Peak (overnight and day) electricity supply or a continuous
electricity supply. Boosting can be controlled via a user operated manual switch. Refer to
“Manual
Controls”
on page 31.
If this water heater is installed as a solar preheater to an in-series water heater, then the booster
heating unit does not need to be connected to a power supply.
