WATER SUPPLY QUALITY
CHLORIDE, WATER HARDNESS AND PH
In high chloride water supply areas, the water can corrode some parts and cause them to
fail. Where the chloride level exceeds 200 mg/litre or Water Hardness level exceeds 200
mg/litre, warranty does not apply to the heat pump unit and tank unit. pH is a measure
of whether the water is alkaline or acidic. In an acidic water supply, the water can corrode
some parts and cause them to fail.
No warranty applies to the heat pump unit and tank unit where the pH is less than 6.5 or
more than 8. The water supply from a rainwater tank unit in a metropolitan area is likely to
be corrosive due to the dissolution of atmospheric contaminants.
Water with a pH less than 6.5 may be treated to raise the pH. It is recommended that an
analysis of the water from a rainwater tank be conducted before connecting this type of
water supply to the system.

CHANGE OF WATER SUPPLY
Changing, or alternating, from one water supply to another can have a detrimental
eect on the operation and/or life expectancy of the water tank unit cylinder, PTR valve,
water heating circulation and the water heat exchanger in the system. Where there is
a changeover from one water supply to another, for example, a rainwater tank 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 the water
should be tested to ensure it meets the warranty requirements in this installation manual.
