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

If wiring from you r 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

Maytacj Customer Service at 1-800-788-8899 for an authorized servicer,

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.

/2 condust opening has been made m the water

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.

3. If metal conduit is used

for the grounding conductor:

CO

 

A. The grounding electrode conductor shall be of copper,

 

 

aluminum, or copperclad aluminum. The material shall

 

 

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

 

 

be of one

continuous

length without a splice or joint.
