AWARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE
ONLY: Thiswater heater isequippedfor one type voltage
only.Check the rating plate near the bottom accesspanel
for the correct voltage. DO NOT use this water heater
with any voltageother than the one shownon the model
rating plate. Failure to usethe correct voltage can cause
problems which can result in DEATH, SERIOUS BODILY
INJURY,OR PROPERTY DAMAGE. If you haveany ques-

aluminum for your old water heater, replace it with cop-
per wire. If youwish to reuse the existingaluminum wire,
havethe connectmnat the water heater made by a com-
petent electrician. Contact your Sears salesperson to

1. Provide a way to easily shut offthe electric power when work-
ing on the water heater. This could be with a circuit breaker
or fuse block in the entrance box or a separate disconnect
switch.
2. Install and connect a circuit directly from the main fuse or
circuit breaker box. This circuit must be the right size and
have its own fuse or circuit breaker. Refer to the chart in the
"ProductSpecifications" section for the correct size wire and
fuse or circuit breaker.
5. Wiring Diagrams (See Wiring Diagrams Section) have been
supplied showing the two most common types of connec-
tions between the water heater and the power supply, You can
easily see which type connection you have by removing the
junction box cover on top of the water heater.
A, Two W'tre Connection Diagrams: is the most common
requiring you to simply connect red to red, black to black,
and the ground wire to the green ground screw in the junc-
tion box of the water beater.
,
7.
B. Three Wire Connection Diagram: is used when you are
connecting the water heater to power a supply that has a
_Time Clock or _Off Peak" Meter. To make these connec-
tions refer to block 1or 2 in this wiring diagram for the type
of system you have.
NOTE: If you have purchased a ,th,tee wire conne ,cfi,_on
water heater but you are not on a T'nne Clocka' or Off
Peak" meter and have a standard two wire connection
_ower supply, simply follow the connection diagram in
lock 3. of the Three WareConnection Diagram.
Use wire nuts and connect the power supply wiring to the
wires inside the water heater's junction.
The water heater must be electrically _grounded" by the
installer. A _reen ground screw has been provided on the
water heater s junction box. Connect ground wire to this
location.
8. Replace the wiring junction cover using the screw provided.
3. If metal conduit is used for the grounding conductor:
A. The grounding electrode conductor shall be of copper,
aluminum, or copperclad aluminum. The material shall
be of one continuous length without a splice orjoint.
B. Rigid metal conduit, intermediate metal conduit, or elec-
trical metallic tubing may be used for the grounding
means if conduit or tubing is terminated in fittings
approved for grounding.
