WATER SUPPLIES
This water heater must be installed in accordance with this advice to be covered by the Solahart
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 Solahart warranty to apply.
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by the Solahart 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 Solahart 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
on page 18 for the Solahart warranty to apply to the water heater
cylinder.

The changing of an anode 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.
