AWARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE
ONLY: This water heater is equipped for one type voltage only. Check the rating plate near the but- tom 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,
ACAUTION

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 dis- connect switch,
2.Instal1 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.
C. Flexible metal conduit or 3 metallic tubing shall be permit-
ted for grounding ifaU the following conditions aremet:
1.The length in anyground return path doesnot exceed
6 feet.
2.The circuit conductorscontained therein areprotected 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 ' .....
heater junction box for the conduit connection.
5. Wiring Diagrams (See "Wiring Diagrams" Section) have been supplied showing the two most common types of con- nections 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 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 june- tion box of the water beater.
B. Three Wire Connection Diagram: is usedwhen 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 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.
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.
