Lower Thermostat
Adjustment
The lower thermostat is adjustable if a different water tempera-
ture "s desired. Read all warnings in the 'Temperature-

counter clockwls' _ e to _ ) decrease the temperature setting.
Failure to install and maintain a new properly listed tempera-
ture-pressure relief valve will release the manufacturer from any
claim which might result from excessive temperature or pressure.
_WARNING
If the temperature-pressure relief valve on the appliance
weeps or dischargesperiodically,this may be due to ther-
mal expansion.Your water heater may havea checkvalve
installed in the water line or a water meter with a check
valve. Consult your local Sears Service Center for further
information, Do not plug the temperature-pressure relief
valve.
Draining
The water heater should be drained if being shut down during
freezing temperatures. Also periodic draining and cleaning of
sediment from the tank may be necessary.

_,WARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to
ensure that (I) no one is in front of or around the outlet
of the temperature-pressure relief valve discharge line,
and (2) the water manually dischargedwill not causeany :
property damage or bodily injury. The water may be
extremely hot.
If after manually operating the valve, it fails to completely
reset and continues to release water, immediately close
