Change of water supply
Changing, or alternating, from one water supply to another can have a detrimental
effect on the operation and/or life expectation of the water tank unit cylinder, PR valve,
water heating circulation and the 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 recirculated 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.
