Service Adjustment, Temperature-Pressure Relief

Service Adjustment

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 "_l_mperature-Regulation" section before proceeding.

1._lhrn "OFF" the electrical power to the water heater at the junction box.

2.Take of/" the upper and/or lower access panel, insulation block and pad.

3.The slotted a_stment (using a screwdriver) can be turned

clockwise (f	"_) to	increase	the temperature settin_ or
counter clockwise (_)		to	decrease the temperature
setting.

4.Replace the insulation block, pad and access panel.

5._lhrn "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

RELIEF VALVE

DISCHARGE PIPE

AWARNING

The temperature-pressure relief valve must be manually operated at least once a year. Caution shouldbe 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 complete- ly reset and continues to release water, immediately close the cold water inlet to the water heater, follow the

draining instructions, and replace the temperature-pres- sure relief valve with a new one.

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.

AWARNING

If the temperature-pressure relief valve on the appliance weeps or dischargesperiodically,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-pres- sure 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.

AWARNING

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 ade- quate 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.

ACAUTION

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.
