If you are not familiar with electric codes and practices, or if
you have any doubt, even the slightest doubt, in your ability to
connect the wiring to this water heater, obtain the service of a
competent electrician. Contact your Sears salesperson to
arrange for a professional electrician.
WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY:
This water heater is equipped for one type voltage only. Check
the rating plate near the bottom access panel for the correct
voltage. DO NOT use this water heater with any voltage other
than the one shown on the model rating plate. Failure to use
the correct voltage can cause problems which can result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE. If you have any questions or doubts consult your
electric company.
If wiring from your fuse box or circuit breaker box was aluminum
for your old water heater, replace it with copper wire. If you
wish to reuse the existing aluminum wire, have the connection
at the water heater made by a competent electrician. Contact
your Sears salesperson to arrange for a professional electrician.
1. Provide a way to easily shut off the electric power when
working 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
“Product Specifications” section for the correct size wire and
fuse or circuit breaker.
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 or
joint.
B. Rigid metal conduit, intermediate metal conduit, or
electrical metallic tubing may be used for the grounding
means if conduit or tubing is terminated in fittings
approved for grounding.
C. Flexible metal conduit or flexible metallic tubing shall
be permitted for grounding if all the following
conditions are met:
• The length in any ground return path does not exceed
6 feet.
• The circuit conductors contained therein are protected
by overcurrent devices rated at 20 amperes or less.
• The conduit or tubing is terminated in fittings approved
for grounding.
For complete grounding details and all allowable exceptions,
refer to the current edition of the NEC - National Electrical Code
NFPA 70.
4. A standard 1/2" conduit opening has been made in the water
heater junction box for the conduit connection.
5. Wiring Diagrams, (see “Wiring Diagrams” section) have been
supplied showing the two most common types of connections
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.
• Two Wire Connection Diagram: 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 junction box of the water heater.
• Three Wire Connection Diagram: is used when you
are connecting the water heater to a power supply
that has a “Time Clock” or “Off Peak” meter. To make
these connections refer to block 1 or 2 in this wiring
diagram for the type of system you have.
NOTE: If you have purchased a three wire connection water
heater but you are not on a “Time Clock” or “Off Peak” meter
and have a standard two wire connection power supply,
simply follow the connection diagram in block 3 of the three
wire connection diagram.
6. Use wire nuts and connect the power supply wiring to the
wires inside the water heater’s junction box.
7. The water heater must be electrically “grounded” by the
installer. A green 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.
