It is recommended that an analysis of the Supply Water be conducted before connecting
the Heat Pump unit to the system.
Figure 14
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.
