Water Supplies - Rheem Electric Domestic Water Heater Installation And Owner's Manual

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.
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
page 12 for warranty to apply to the water heater cylinder.
Total Dissolved Solids
0 – 40 mg/L
40 – 150 mg/L
150 – 400 mg/L
400 – 600 mg/L
600 – 2500 mg/L
2500 mg/L +
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.
