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
The vitreous enamel lined cylinder of the water heater is covered by the
Everhot warranty when the total dissolved solids (TDS) content in the water is
less than 600 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 Everhot 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 Everhot warranty to apply to the
water heater cylinder (refer to
on page 15). The black anode is typically fitted as standard.

Note:
The Everhot warranty does not apply to the cylinder if the water
heater is connected at any time to a water supply where the TDS content
of the water exceeds 600 mg/L.
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
on page 15).
