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 connect the wiring to this water heater, obtain the service of a
competent electrician. Call Maytag Customer Service at
AWARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: This water heater is equipped for one type
voltage only. Check the rating plate near the bot- 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,
&CAUTION
If wiring from your fuse box or circuit breaker box was aluminum for your old water beater, 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. Call

1.Provide a way to easily shut offthe 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 or circuit breaker.
3. If metal conduit is used for the grounding conductor:
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 |
|
A. The grourtding electrode conductor shall be of copper, | 16 |
approved for grounding. |
C. Flexible metal conduit or 3 metallic tubing shall be per-
mitred for grounding if all the following conditions are met:
1.The length in any ground return path doesnot 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 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 con- nections between the water heater and the power supply.
YOUcan easily see which type connection you have by
removing the junction box cover on top of the water heater.
A. TwoWire Connection Diagrams: is the most common
requiring you to simply connect red to red, black to black, and the ground wire to the greenground screwin thejunc- tion 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 "OffPeak" 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 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.
