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 accesspanel.
5. _lhrn "ON" the power supply.
Temperature-Pressure Relief
Valve Operation
AWARNING
If the temperature-pressure relief valveon the appliance
weepsor dischargesperiodically,this may bedue to ther-
mal expansion. Your water heater may have a check
valve installedin the water line or a water meter with a
checkvalve. Consultyour localSears Service Center for
further information. Do not plugthe 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 accesspanels or servicing the water heater, make
sure the electrical supplyto the water heater isturned
"OFF". Failure to do this could result in DEATH, SERI-
OUS BODILY INJURY,OR PROPERTY DAMAGE.
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 leastoncea year.Caution shouldbe taken to
ensurethat (I) no one isin front of or around the outlet
of the temperature-pressure relief valve dischargeline,
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
closethe cold water inlet to the water heater, follow the
draining instructions,and replace the temperature-pres-
sure relief valvewith a new one.
• CLOSE the cold water inlet valveto 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 valveto 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.
A CAUTION
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.
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 excessivetemperature or pressure.
