MAINTENANCE REQUIREMENTS

TEMPERATURE LIMITING VALVE
A RheemPlus water heater is fitted with a temperature limiting valve at the outlet.
The valve is set so the water temperature from the fixtures used primarily for
personal hygiene does not exceed 50°C.
The valve should be checked for performance at least every twelve (12) months.
This can be performed by using a thermometer to measure the water
temperature from the hot tap used primarily for personal hygiene nearest to the
water heater. If the water being delivered is at a temperature exceeding 50°C,
phone Rheem Service or their nearest Accredited Service Agent to arrange for
an inspection.
The valve must be replaced at intervals not exceeding five (5) years, or more
frequently in areas where there is a high incidence of water deposits (refer to
"Water Supplies"
temperature up to 70°C being delivered at the hot tap, increasing the risk of scald
injury.
MINOR MAINTENANCE EVERY SIX MONTHS
It is recommended minor maintenance be performed every six (6) months. Minor
maintenance can be performed by the dwelling occupant.
The minor maintenance includes:
•
Operate the easing lever on the temperature pressure relief valve. It is very
important the lever is raised and lowered gently. Refer to
on page 9.
Warning: Water discharged from the temperature pressure relief valve
drain line will be hot. Exercise care to avoid any splashing of water by
standing clear of the drain line's point of discharge when operating the valve's
easing lever.
•
Operate the easing lever on the expansion control valve (if fitted). It is very
important the lever is raised and lowered gently. Refer to
on page 9.
•
Check the performance of the temperature limiting valve (RheemPlus model).
Use a thermometer to measure the water temperature from the hot tap used
primarily for personal hygiene nearest to the water heater. If the water
temperature exceeds 50°C, phone Rheem Service or their nearest
Accredited Service Agent to arrange for an inspection. Refer to
