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.
FIGURE 27.
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 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.
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.
1. 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, SErIouS bodIly INjury, or
ProPErTy dAMAGE.
