Service and Adjustment (cont'd)
Upper and Lower Thermostat
Adjustment
(Refer to thermostat illustrations under
"Thermostats")
NOTE: It is not necessary to adjust the upper thermostat.
However, if it is adjusted above the factory set point of
120°F (HOT) is is recommended that it not be set higher
than the lower thermostat setting.
The upper and lower thermostats are adjustable if a different
water temperature is desired. Read all warnings in the
"Temperature-Regulation" section before proceeding.
1. Turn "OFF" the electrical power to the water heater at the
junction box.
2. Take off the upper and/or lower access panel, insulation
block and pad.
3. The slotted adjustment (using a screwdriver) can be turned
clockwise ( ) to increase the temperature setting or
counter clockwise (
setting.
4. Replace the insulation block, pad and access panel.
5. Turn "ON" the power supply.
Temperature-Pressure Relief
Valve Operation
The temperature-pressure relief valve must be manually operated
at least once a year.
TEMPERATURE-PRESSURE
DISCHARGE PIPE
WARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to
ensure that (1) no one is in front of or around the outlet
of the temperature-pressure relief valve discharge line,
and (2) the water manually discharged will not cause any
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
the cold water inlet to the water heater, follow the drain-
ing instructions, and replace the temperature-pressure
relief valve with a new one.

RELIEF VALVE
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.
If the temperature-pressure relief valve on the appliance
weeps or discharges periodically, this may be due to ther-
mal expansion. Your water heater may have a check valve
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.
• Before beginning turn "OFF" the electric power supply to
the water heater.
HAZARD OF ELECTRICAL SHOCK! Before removing
any access panels or servicing the water heater, make
sure the electrical supply to the water heater is turned
"OFF". Failure to do this could result in DEATH, SERI-
OUS BODILY INJURY, OR PROPERTY DAMAGE.
• CLOSE the cold water inlet valve to the water heater.
• OPEN a nearby hot water faucet and leave open to allow for
draining.
• Connect a hose to the drain valve and terminate to an
adequate drain or outdoors.
• OPEN the water heater drain valve to allow for tank
draining.
NOTE: If the water heater is going to be shut down and
drained for an extended period, the drain valve should be
left open with hose connected allowing water to terminate
to an adequate drain.
• Close the drain valve.
• Follow "Filling the Water Heater" instructions in the
"Installation Instructions" section.
• Turn "ON" power to the water heater.
Never use this water heater unless it is completely full
water. To prevent damage to the tank and heating ele-
ment, the tank must be filled with water. Water must
flow from the hot water faucet before turning "ON"
power.
