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 for the water supply being used must be selected and fitted to the water
heater for the Solahart warranty to apply to the water heater cylinder (refer to
“Water Supplies”
on page 17
and the Anode Selection chart on page 17). The black anode is typically fitted as standard.

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
“Caution”
on page 18).
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 Solahart warranty.
BOOSTER HEATING UNIT
The booster heating unit is for heating the water at times of low solar energy gain, such as during very
cloudy or rainy weather, or during the colder months. Refer to
“Connections – Electrical”
on page 43 for
electrical connection requirements and control options of the booster heating unit.
If this water heater is installed with an in-series booster, then the electric booster heating unit in the solar
storage tank will not need to be connected to a power supply.
