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
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by 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
installed. The use of an incorrect colour coded anode will void the cylinder warranty and 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 warranty to apply to the water heater cylinder (refer to
Selection chart
on page 14). The black anode is typically fitted as standard.
If the water supply has a TDS greater than 150 mg/L and a green anode has not been changed to a black
anode, or if the TDS is greater than 600 mg/L and the anode has not been changed to a blue anode, there is
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
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 13 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
a continuous, or a time of use, or an extended Off-Peak (overnight and day) or an Off-Peak (overnight)
electricity supply. Boosting can be controlled via a timer. Refer to
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.
