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 number of components in this water heater.
Where there is a change
over 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 the Solahart
warranty to apply.

CAUTION
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.
If, under these conditions, the water heater has not been used for two or more weeks
the following procedure should be carried out before using any electrical appliances
(automatic washing machines and dishwashers) which are connected to the hot water
supply.
The hydrogen, which is highly flammable, should be vented safely by opening a hot tap
and allowing the water to flow. There should be no smoking or naked flame near the tap
whilst it is turned on. Any hydrogen gas will be dissipated. This is indicated by an unusual
spurting of the water from the tap. Once the water runs freely, any hydrogen in the system
will have been released.
SATURATION INDEX
The saturation index (SI) is used as a measure of the water’s corrosive or scaling
properties. The saturation index figures stated are calculated using a water temperature
of 80°C.
Where the saturation index is less than –1.0, the water is very corrosive and the Solahart
warranty does not apply to the water heater. In a corrosive water supply, the water can
attack copper parts and cause them to fail.
Where the saturation index e0.40, the water is very scaling and the Solahart
warranty does not apply to the water heater.
Water which is scaling may be treated with a water softening device to reduce the
saturation index of the water.
CHLORIDE AND PH
Where the chloride level exceeds 250 mg/L the Solahart warranty does not apply to the
water heater. In a high chloride water supply, the water can corrode stainless steel parts
and cause them to fail.
6.Maintenance and repair
Where the pH is less than 6.0 the Solahart warranty does not apply to the water heater.
pH is a measure of whether the water is alkaline or acid. In an acidic water supply, the
water can attack stainless steel parts and cause them to fail.
Water with a pH less than 6.0 may be treated to raise the pH. The water supply from a
rainwater tank in a metropolitan area is likely to be corrosive due to the dissolution of
atmospheric contaminants.
SUMMARY OF WATER CHEMISTRY ADVICE AFFECTING WARRANTY
The water heater is not suitable for certain water chemistries. Those chemistries are listed
below. If the water heater is connected at any time to a water supply with the following water
chemistry, the Solahart warranty will not cover any resultant faults:
Water Chemistry
Total Dissolved Solids (TDS) > 2500 mg/L
Total Dissolved Solids (TDS) not suitable for anode type
Saturation Index (SI) < -1.0
Saturation Index (SI) > +0.4
Chloride > 250 mg/L
pH < 6.0

6.5 Product Warranty:
2 Years on cylinder
2 Years on Heat Exchanger, Gas System, Compressor / sealed systems
1 Year on other components
The decision of whether to repair or replace a faulty component is at Solahart’s sole discretion.
This warranty is void if there is:
a.Failure to maintain the water heater in accordance with the Owner's Guide and Installation
Instructions.
b.Transport damage.
c.Fair wear and tear from adverse conditions (for example, corrosion).
d.Cosmetic defects.
e.Ice formation in the waterways of a water heater system incorporating a freeze protection
system where the electricity supply has been switched off or has failed.
f.Where a failed component or cylinder is replaced under this warranty, the balance of the
original warranty period will remain effective. The replacement does not carry a new
Solahart warranty.
