MAINS WATER SUPPLY 
Where the mains water supply pressure exceeds that shown in the table below, 
an approved pressure limiting valve is required and should be fitted as shown 
in the installation diagram 

 

Relief valve setting 

1000 kPa 

Expansion control valve setting * 

850 kPa 

 

With expansion control valve 

680 kPa 

Without expansion control valve 

800 kPa 

200 kPa 

* Expansion control valve not supplied with the water heater. 

 

 
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.
