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 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 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
approved for grounding.
C. Flexible metal conduit or 3 metallic tubing shall be per-
mitted 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 current edition of the NEC, National Electrical
Code NFPA 70.
4. A standard
1
⁄
2
″ conduit opening has been made in the water
heater junction box for the conduit connection.
5. A wiring diagram (See “Wiring Diagram” Section) has been
supplied showing the connections between the water heater
and the power supply. You can easily see the connection by
removing the junction box cover on top of the water heater.
Connect red to red, black to black, and the ground wire to
the green ground screw in the junction box of the water
heater.
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.
CAUTION
Never use this water heater unless it is completely
full of water. To prevent damage to the tank and
heating element, the tank must be filled with
water. Water must flow from the hot water faucet
before turning on power.
WARNING
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 heater, 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
Maytag Customer Service at 1-800-788-8899 for an
authorized servicer.
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
