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 junction box of the water heater.
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. _lb make these con-
nections 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.
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. 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.
6.
7.
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 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.
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.
