Installation Instructions (cont’d)
A CAUTION
Never use this water heater unless it is completely full of
water. To prevent damage to the tank and heating eie*
ment, the tank must be filled with water. Water must
flow from the hot water faucet before turning on power.
You must provide all wiring of the proper size outside of the
wearer heater^ You must obey local codes and electric company
requirements when you install this wiring.
If you are not familiar with electric codes and practices, or if you
have any doubt, even the slightest doubt, in your ability to con­
nect the wiring to this water heater, obtain the service of a com­
petent electrician. Contact your Sears salesperson to arranee for
a professional electrician.
A WARNING
WATER HEATERS EQUIPPED POR ONE VOLTACE
ONLY: This water heater is equipped for one type voltage
only. Cheek the rating plate near the bottom access pane!
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 DAHAQE. If you have any ques­
tions or doubts consult your electric company.
A CAUTION
If wiring from your fuse box or circuit breaker box was
aluminum for your old water heater, replace it with cop­
per wire. If you wish to reuse the existing aluminum wire,
have the connection at the water heater made by a com­
petent electrician. Contact your Sears salesperson to
arrange for a professional electrician.
I - Provide a way to easily shut off the electric power when work­
ing on the water heater. This could be wim a circuit breaker
or fuse block in the entrance box or a separate disconnect
switch
2, Install and connect a circuit direedy from the main fuse or
circuit breaicer bos. 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 materia] shall
be of one continuous length without a splice or joint.
B- Rigid metal conduit, intermediate metal conduit, or elec­
trical metallic tubing may be used for the grounding
means if conduit or cubing is terminated in fittings
approved fot grounding.
C. Flexible metal conduit or flexible metallic tubing shall be
permitted for grounding if all the following concGtions are
met;
1 The length in any ground return path does not exceed
6 feet,
2.. The circuit conductors contained therein are protected
by overcutrent devices rated at 20 amperes or less.
3 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 National Electrical Code.
4. A standard Vz" 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 connec­
tions between the water heater and the power supply. You can
easily see which type connection you nave by removing the
junction box cover on top of the water heater,
A. Two Wire 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 heater.
B. Three Wire Connection Diagram: is used when you are
connecting the water heater to power a supply chat has a
“Time Clock” or “Off Peale” Meter. To make these connec­
tions 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 uot 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.
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.
