WATER SUPPLIES
This water heater must be installed in accordance with this advice to be
covered by the Aquamax warranty.
This water heater is manufactured to suit the water conditions of most public
reticulated water supplies. However, there are some known water chemistries
which can have detrimental effects on the water heater and its operation and / or
life expectancy. If you are unsure of your water chemistry, you may be able to
obtain information from your local water supply authority. This water heater
should only be connected to a water supply which complies with these guidelines
for the Aquamax warranty to apply.
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by the
Aquamax 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 Aquamax 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 must be selected and fitted to the water heater
in accordance with the following advice and the
page 20 for the Aquamax warranty to apply to the water heater cylinder.

The changing of anodes must be carried out by a qualified person.
Note:
Some water analysis reports may state the conductivity of the water rather
than the level of total dissolved solids. Conductivity, measured in microsiemens
per centimetre (
µ
S / cm), is directly proportional to the TDS content of the water.
TDS, in mg / L, is approximately 70% of the conductivity in
µ
S / cm.
