Rheem 511161 Owner's Manual And Installation Instructions page 13


Check the insulation on the solar hot and solar cold pipes. If required, insulate exposed pipe work and
repair or replace degraded insulation.

Visually check the unit for any potential problems.

Inspect all connections.

Check the drain line from the safe tray (if one is installed) is not blocked.
Note: The solar storage tank may need to be drained during this service. After the completion of the service,
the solar storage tank will take some time to reheat the water by solar gain.
If this solar storage tank is installed with an integrated or remotely installed Rheem in-series continuous flow
gas booster, then for the booster's safe and efficient operation, it is recommended a major service be
conducted on the gas booster every five (5) years. Another type of in-series booster may have its own
recommended service schedule. Refer to the Owner's Guide and Installation Instructions supplied with the
booster water heater.
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
"Temperature Pressure Relief Valve Running"
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 (6) months. Refer to
Maintenance Every Six Months"
important the lever is raised and lowered gently.
DANGER: Failure to do this may result in the water
heater cylinder failing, or under certain circumstances,
exploding.
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.
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 to arrange for an inspection.
The temperature pressure relief valve should be replaced at
intervals not exceeding five (5) years, or more frequently in
areas where there is a high incidence of water deposits
