It is very important the lever is raised and lowered gently. Refer to "Minor
Maintenance Every Six Months" on page 19.
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 either valve's easing lever.
DANGER: Failure to operate the easing lever on the relief valve once every
six (6) months may result in the storage tank 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 must be checked. Phone Rheem Service or their nearest Accredited
Service Agent / Centre to arrange for an inspection.
The temperature pressure relief valve should be replaced at intervals not
exceeding five (5) years and the expansion control valve should be checked for
performance or replaced at intervals not exceeding five (5) years. The checking
of the valves performance or replacement should occur more frequently in areas
where there is a high incidence of water deposits. Refer to "Water Supplies" on
page 21.
