REGULAR CARE 
 
TEMPERATURE PRESSURE RELIEF VALVE 
This valve is near the top of the water heater and is essential for its safe operation. It is possible for the 
valve to release a little water through the drain line during each heating period. This occurs as the water 
is heated and expands by approximately 1/50 of its volume. 
 
Continuous leakage of water from the valve and its drain line may indicate a problem with the water 
heater (refer to 
 on page 15). 
 
 Warning: Never block the outlet of this valve or its drain line for any reason. 
 
Operate the easing lever on the temperature pressure 
relief valve once every six months. It is very important 
you raise and lower the lever gently.

 DANGER: Failure to do this may result in the water 
heater cylinder failing, or under certain circumstances, 
exploding. 
 
If water does not flow freely from the drain line when 
the lever is lifted, then the water heater should be 
checked by your nearest Solahart Dealer. 
 
The temperature pressure relief valve should be 
checked for performance or replaced at intervals not 
exceeding 5 years, or more frequently in areas where 
there is a high incidence of water deposits (refer to 
 on page 36). 
 
EXPANSION CONTROL VALVE 
In many areas, including South Australia, Western Australia and scaling water areas, an expansion 
control valve is fitted to the cold water line to the water heater. The expansion control valve may 
discharge a small quantity of water from its drain line during the heating period instead of the 
temperature pressure relief valve on the water heater. 
 
Operate the easing lever on the expansion control valve once every six months. It is very important 
you raise and lower the lever gently. 
The expansion control valve should be checked for 
performance or replaced at intervals not exceeding 5 years, or more frequently in areas where there is 
a high incidence of water deposits. 
 
COLLECTOR GLASS 
Ensure the glass on your solar collectors is free of dust, salt spray or any other matter, which may 
reduce the effectiveness of the solar collectors. If the collector glass becomes dirty, hose down or if the 
solar collectors are accessible, wash the collector glass with water and a soft brush when the solar 
collectors are cool. Have any trees trimmed which may shade the solar collectors.
