Facts to Consider About the Facts to Consider About The
Location Convertible Lower Element
You should carefully choose an indoor location for the new
water heater, because the placement is a very important consid-
eration for the safety of the occupants in the building and for
the most economical use of the appliance. This water heater is
not intended for outdoor installation.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
• The location selected should be indoors as close to and as
centralized with the water piping system as possible. This
water heater, as well as all water heaters, will eventually leak.
Do not install without adequate drainage provisions where
water flow will cause damage.
_CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplishedin sucha manner
that if the tank or anyconnectionsshouldleak, the flow of
water will not causedamage to the structure. When such
locationscannot be avoided, a suitable drain pan should
be installedunder the water heater. Drain pansare avail-
able at your local Searsstores. Sucha drain pan must be
piped to an adequate drain. Under no circumstances is
the manufacturer or Searsto be held liable for any water
damagein connectionwith this water heater.
The Upper Element (if a double element model), is a conven-
tional 3800 watt element which only operates at its rated
wattage on 240 volts. (See rating plate on water heater).
The Lower Element of the water heater can be converted from
operation at 3800 watts to 5500 watts on a 240 volt system.
Read and follow water heater warnings and instructions. If after
reading these instructions in this manual, if you do not under-
stand any portion, call Sears Service Center.
AWARNING
Before making the conversionto 5500 watt.s, check the
(I) power supply...mustbe 240 volts, (2) wwmg...10.gang.e
AWG, Type TW, 60°C or equivalent, and (3) Ctrcutt
breakersor fusing...capableof 30 amp loading. Also, the
installation must conform with this manual, local codes
and electric utility rules. Failure to comply can result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE.
A CAUTION . I
INSTALLATION IN RESIDENTIAL GARAGES. The I
water heater must be located and/or protected so it is
not subjectto physicaldamage bya movingvehic e.
" The location selection must provide adequate dearances for
servicing and properoperation of the water heater.
NOTE: Whether or not the element conversion is made the
model rating plate must be marked. Using a hardpoint ink
pen, check the appropriate block within the model rating
plate, which is located adjacent to the lower access panel.

connections.
If a water heater is installed in a closed water supply system;
such as one having a back-flow preventer, check valve, water
meter with a check valve, etc. in the cold water supply; means
shall be provided to control thermal expansion. Contact the
local utility or local Sears Service Center on how to control this
situation.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the cold water inlet connec-
tion. Do not solder the cold water supply line directly to the
cold water inlet. It will harm the dip tube and damage the

Start Up Conditions
THERMAL EXPANSION
Water supply systems may, because of such events as high line
pressure, f_equent cut-offs, the effects of water hemmer among
others, have installed devices such as pressure reducing valves,
check valves, back flow preventers, etc._to control these types of
problems. When these devices are not equipped with an internal
by-pass, and no other measures are taken, the devices cause the
water system to be closed. As water is heated, it expands (ther-
mal expansion) and closed systems do not allow for the expan-
sion of heated water.
The water within the water heater tank expands as it is heated and
increases the pressure of the water system. If the relieving point of
the water heater s temperature-pressure relief valve is reached, the
valve will relieve the excesspressure. The temperature-pressure
relief valve is not intendedfor the constant relief of thermal
expansion. This is an unacceptable condition and must be cor-
rected.
It is recommended that any devices installed which could create a
closed system have a by-pass and/or the system have an expan-
sion tank to relieve the pressure built by thermal expansion.
Thermal expansion tanks are available from Sears stores and
through the Sears Service Centers. Contact the local plumbing
inspector, water supplier and/or the Sears Service Center for
assistance in controlhng these situations.

NOT ENOUGH OR NO HOT WATER
In a new installation, the water heater may not be properly
connected. Make sure the cold water supply valve is open.
Review and check piping installation. Make sure that the
cold water line is connected to the cold water inlet to the
water heater and the hot water line to the hot water outlet
on the water heater.
• Make sure the electrical supply to your water heater is
"ON".
• Check for loose or blown fuses in your water heater circuit.
Circuit breakers weaken with age and may not handle their
rated load and should be replaced.
Make certain the disconnect switch, if used, is in the "ON"
position.
Check to see the electric service to your house has not been
interrupted. If this is the case, contact the electric company.
• Are the thermostats set to the desired temperature? See
"Temperature Regulation" section.
• If you had experienced very hot water and now no hot
water, the problem may be due to the high temperature shut
off system. See _High Temperature Shut Off System" in the
Troubleshooting Guide section.
• During very cold weather, the incoming water will also be
colder and it will require a longer time to become heated.
• The hot water usage may exceed the capacity of the water
heater. If so, wait for water heater to recover after abnormal
demand. Also examine pipes and faucets for possible water
leaks.
• If you can not determine the problem, then call the Sears
Service Department.
