flow from the hot water faucet before turn ng on power.
You must provide all wiring of the proper size outside of the water 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 arrange for a professional electrician.
AWARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: This water heater is equipped for one type volt- age 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 shownon 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 questionsor doubts consult your electric company.
•, 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, havethe connection at the water heater made by a com- petent electrician. Contact your Sears salesperson to arrange for a professionalelectrician.
1.Provide a way to easily shut off the 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
"Product Specifications" section for the correct size wire and fuse 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 elec- trical 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:
1.The length in any ground return path does not exceed 6 feet.
2.The circuit conductors contained therein are protected by overcurrent 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 latest edition of the National Electrical Code.
,4. A standard _" 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 easi- ly see which type connection you have by removing the junc- tion 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 Ware 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 1 or 2 in this wiring diagram for the type of system you have.
NOTE: If you have purchased a three wire connection
,heater but you are not on a "Time Clock" or "Off _a_r, meter and have a standard two wire connection
_ower supply, simply follow the connection diagram in lock 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.
