NOTE: It is not necessary to adjust the upper thermostat.
However, if it is adjusted above the factory set point of 120°F
(49°C), it 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 electric power to the water heater at the
junction box.
2. Take off the upper and/or lower access panel, insulation cap
with handle.
3. The slotted adjustment (using a screwdriver) can be turned
clockwise (
) to increase the temperature setting or
counter clockwise (
) to decrease the temperature setting.
4. Replace the insulation cap with handle and access panel.
5. Turn “ON” the power supply.
Anode Rod Inspection
The anode rod is used to protect the tank from corrosion. Most
hot water tanks are equipped with an anode rod. The submerged
rod sacrifices itself to protect the tank. Instead of corroding the
tank, water ions attack and eat away the anode rod. This does
not affect the water’s taste or color. The rod must be maintained
to keep the tank in operating condition.
Anode deterioration depends on the water conductivity, not
necessarily water condition. A corroded or pitted anode rod
indicates high water conductivity and should be checked and/
or replaced more often than an anode rod that appears to be
intact. Replacement of a depleted anode rod can extend the life
of your water heater. Inspection should be conducted by calling
Sears Service Center. At a minimum the anode(s) should be
checked annually after the warranty period.
Temperature-Pressure Relief
Valve Operation
The temperature-pressure relief valve must be manually
operated at least once a year.
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.
FIGURE 28.
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 draining instructions, and
replace the temperature-pressure relief valve with a new one.
Failure to install and maintain a new properly listed temperature-
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 thermal 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.
