, Before removing any access
panels or servicing the water
heater, make sure the electrical
supply to the water heater is
turned "OFF".

Temperature-Pressure Relief
Valve Operation
The temperature-pressure relief valve must be manually
operated at least once a year.
• Burn hazard
• Hotwater discharge.
• Keep clear of reHiefvalve
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.

3. The slotted adjustment (using a screwdriver) can be turned
clockwise ( f_ ) 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
Property Damage Hazard
, Avoid water heater damage.
• Inspection and replacement of anode as needed.
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 heaten Inspection should be conducted by
calling Sears Service Center. At a minimum the anode(s)
should be checked annually after the warranty period.
DISCHARGE PiPE
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.
