MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table, an approved pressure limiting
valve is required and should be fitted as shown in the installation diagram (refer to diagram on page 35).

TANK WATER SUPPLY
If the water heater is supplied with water from a tank supply and a minimum water supply pressure of
200 kPa at the water heater cannot be achieved, then a pressure pump system must be installed to allow the
solar circuit system to operate. Care must be taken to avoid air locks. The cold water line from the supply
tank should be adequately sized and fitted with a full flow gate valve or ball valve.
