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.
ANODE TYPES
The vitreous enamel lined cylinder of this water heater is covered by warranty where the total dissolved
solids (TDS) content in the water is less than 2500 mg/L and when the correct colour coded anode is used.
The use of an incorrect colour coded anode may shorten the life of the water heater cylinder and will void the
cylinder warranty.
The correct colour coded anode for the water supply being used must be selected and fitted in the water
heater. Refer to
“Water Supplies”
on page 9 and the
“Water Chemistry Charts”
for TDS on page 11. The
black anode is fitted as standard.

Blue (no cylinder warranty)
If the water supply has a TDS greater than 150 mg/L and a green anode has not been changed to an orange
or 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
“Caution”
on page 10).
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.
