WATER SUPPLY
The minimum and maximum water pressures for the various systems are listed in Table 5 .
Approved pressure limiting valves may be required if the 'Maximum' rated water supply pressures
are exceeded. For gas boosted systems to achieve the rated flow through the outlet of the
continuous flow water heater, the minimum water supply pressures must be supplied.
The systems will operate at lower pressures but the rated flow will not be achieved.
Water chemistry and impurity limits are detailed in the separate 'Warranty conditions' document.
Most metropolitan water supplies fall within these requirements. If you are unsure about water
quality, contact your water authority. If sludge or foreign matter is present in the water supply, a
suitable filter should be incorporated in the water supply to the storage cylinder.
HOT WATER DELIVERY TEMPERATURE
Local regulations and/or the requirements of AS/NZS 3500.4 must be considered regarding the
temperature limitations of hot water supplied to areas used primarily for personal hygiene. The
temperature of water to these areas is limited to 45°C for early childhood centres, primary and
secondary schools and nursing homes or similar facilities for young, aged, sick or people with
disabilities and 50°C for all other buildings. To comply with these requirements, a temperature
limiting device, such as a thermostatic mixing or tempering valve, will be required on all solar hot
water systems as detailed in
Figures 4 and 5.
