TEMPERATURE LIMITING VALVE 
A RheemPlus water heater is fitted with a temperature limiting valve at the hot 
water outlet. The valve is set to deliver water not exceeding 50
°C. 
 
The valve should be checked for performance every twelve months. This can 
be performed by measuring the water temperature from a hot tap with a 
thermometer. If the water is being delivered at a temperature exceeding 50
°C, 
phone your nearest Rheem Service Department or Accredited Service Agent to 
arrange for an inspection. 
 
The valve should be 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 33). Failure to do this may result in water at a 
temperature up to 70
°C being delivered at the hot tap, increasing the risk of 
scald injury. 
 
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.
