Use the instructions under option 2 or 3 if your home has a 3-wire receptacle (NEMA type 10-30R). Use option 2 if local codes and ordinances permit the connection of a chassis ground to the neutral connector. If this is not permitted, use option 3.

Review the following options to determine the appropriate electrical connection for your home:

Electric Dryer Only

If this type is available at your home. you will be connecting to a fused disconnect or circuit breaker box

Important : Grounding through the neutral conductor is prohibited for (1) new branch-circuit installations, (2) mobile homes, and (3) recreational vehicles, and (4) areas where local codes prohibit grounding through the neutral conductor.

Prepare minimum 5ft(1.52m) of length in order for dryer to be replaced.

First, peel 5 inch (12.7cm) of covering material from end. Make a 5 inch of ground wire bared. After cutting 1

/2 inch (3.8cm) from 3 other wires. peel insulation back 1inch (2.5cm). Make ends of 3 wires a hook shape.

Then, put the hooked shape end of the wire under the screw of the terminal block(hooked end facing rightward) and pinch the hook together and screw tightly.

Use the instructions under option 1 if your home homehas a 4-wire receptacle (NEMA type 14-30R).

If this type is available at your home. you will be connecting to a fused disconnect or circuit breaker box

1. Connect neutral wire(white) of power cord to center

terminal block screw.

2. Connect red and black wire to the left and right

terminal block screws.

3. Connect ground wire(green) of power cord to external

ground screw and move neutral ground wire of appliance and connect it to center screw.

4. Make sure that the strain relief screw is tightened.

and be sure that all terminal block nuts are on tight and power cord is in right position.

3-wire connection : Direct wire

1. Connect the neutral wire (white) of the power cord to the center terminal block screw.

2. Connect the red and black wires to the left and right terminal block screws.

3. Connect the ground wire (green) of the power cord to the external ground screw. Remove the neutral ground wire of appliance and connect it to center screw.

4. Make sure that the strain relief screw is tightened and that all terminal block nuts are tight and the power cord is in the right position.

• lf your local codes or ordinances do not allow the use of a 3 wire connection, or you are installing your dryer in a mobile home, you must use a 4wire connection.

Option 1: 4-wire connection with

a Power supply cord.

1. Remove the appliance ground wire (D) (green) fromthe external ground connector screw and reconnect it, together with the center, white, neutral wire (E) to the center, silver colored, terminal block screw.

2. Connect the other two power cord wires (red and black) to the left and right terminal block screws and tighten securely.

3. Tighten the strain relief screws securely.

4. Connect an independent ground wire (F) from the external ground connector screw to a proper ground. (The ground wire must be long enough to allow the appliance to be moved, if necessary, for service or cleaning.)

lf your local codes or ordinances permit the connection of a frame-grounding conductor to the neutral wire, use these instructions. If your local codes or ordinances do not allow the connection of a frame-grounding conductor to the neutral wire, use the instructions under Section 3: Optional

3-wire connection.

1. Connect the neutral (white or center) wire (B) to the center, silver colored, screw (A) and tighten securely.

2. Connect the other two power cord wires (red and black) to the left and right terminal block screws and tighten securely.

3. Tighten the strain relief screws (C) securely.

Option 2: 3-Wire Connection with

a Power Supply Cord

• If your local codes or ordinances do not allow the connection of a frame-grounding conductor to the neutral wire, use the instructions under this section.

Option 3: Optional 3-wire

connection.

3-2. Connect Gas Supply Pipe (Gas Dryer ONLY)

1. Make certain your dryer is equipped for use with the type of gas in your laundry room. Dryer is equipped at the factory for Natural Gas with a 3/8” N.P.T. gas connection.

2. Remove the shipping cap from the gas connection at the rear of the dryer. Make sure you do not damage the pipe thread when removing the cap.

3. Connect to gas supply pipe using a new flexible stainless steel connector.

4. Tighten all connections securely. Turn on gas and check all pipe connections (internal & external) for gas leaks with a non-corrosive leak detection fluid.

5. For L.P. (Liquefied Petroleum) gas connection, refer to section on Gas Requirements.

For further assistance, refer to section on Gas Requirements.
