REGULAR CARE
MINOR SIX MONTH MAINTENANCE
It is recommended minor maintenance be performed every six months by the dwelling occupant.
The minor maintenance includes:
Operate the easing lever on the temperature pressure relief valve. It is very important you raise and
lower the lever gently. Refer to
“Temperature Pressure Relief Valve”
on page 11.
Warning:
Exercise care to avoid any splashing of water, as water discharged from the drain line will
be hot. Stand clear of the drain line‟s point of discharge when operating the valve‟s lever.
Operate the easing lever on the expansion control valve (if fitted). It is very important you raise and
lower the lever gently. Refer to
“Expansion Control Valve”
on page 11.
Check the performance of the temperature limiting valve.
Measure the water temperature from the hot tap nearest to the water heater with a thermometer. If the
water temperature exceeds 50°C, phone Rheem Service or their nearest Accredited Service Agent to
arrange for an inspection. Refer to
“Temperature Limiting Valve”
on page 11.
Check the drain line from the safe tray (if one is installed) is not blocked.
MAJOR FIVE YEAR SERVICE
It is recommended a major five year service be conducted on the water heater.
Warning
