INSTALLATION
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.
Keep temperature settings down. Lower temperatures reduce heat losses and prolong cylinder life. Do not
set the controlling electronic thermostat above 70°C unless it is necessary. A time clock to control the
electrical supply can be used to switch off the water heater during hours or days when it is not in use.
ANODE
The vitreous enamel lined cylinder of the water heater is only covered by the Rheem 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 Rheem 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 Rheem warranty to apply to the water heater cylinder (refer to
and the
Anode Selection chart
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
SADDLING PIPE WORK
To prevent damage to the cylinder when attaching pipe clips or saddles to the water heater jacket, we
recommend the use of self drilling screws with a maximum length of 13 mm. Should pre drilling be required,
extreme caution must be observed when penetrating the jacket of the water heater.
Note: If the cylinder is damaged as a result of attaching pipe clips or saddles to the jacket, any
resultant faults will not be covered by the Rheem warranty.
