WATER SUPPLIES

This water heater must be installed in accordance with this advice to be covered by the 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 water heater warranty to apply.

CHANGE OF WATER SUPPLY

The changing or alternating from one water supply to another can have a detrimental effect on the operation

and / or life expectation of a water heater cylinder, a temperature pressure relief valve and a solar collector in

a direct solar water heater system.

Where there is a changeover from one water supply to another, e.g. a rainwater tank supply, bore water

supply, desalinated water supply, public reticulated water supply or water brought in from another supply,

then water chemistry information should be sought from the supplier or it should be tested to ensure the

water supply meets the requirements given in these guidelines for warranty to apply.

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 must be selected and fitted to the water heater in accordance with the

following advice and the Anode Selection chart on page 17 for warranty to apply to the water heater cylinder.

The changing of anodes must be carried out by a plumber or authorised service 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 (µS / cm), is directly proportional to

the TDS content of the water. TDS, in mg / L, is approximately 70% of the conductivity in µS / cm.
