Electricity

Use an individual, grounded electrical outlet located within 2 ft. (61 cm) of either side of the appliance.

WARNING

•Do not install or store the appliance in an area where it will be exposed to water and/or weather.

NOTE

•Check code requirements that limit, or do not permit, installation of the dryer in garages, mobile homes or sleeping quarters. Contact your local building inspector.

D	25 1/4" (64 cm)
D'	26 3/8" (67 cm)
D"	45 1/4" (115 cm)

Ambient Temperature

Install the appliance in an area where the temperature is over 45 (7 ).

If the temperature around the appliance is too low, the appliance might not shut off at the end of an automatic cycle. This can result in longer drying times.

Flooring

To avoid noise and vibration, the appliance must be installed and leveled on a solidly constructed floor with a maximum slope of 1 inch (2.5 cm). If required, adjust the leveling legs to compensate for the unevenness of the floor.

NOTE

•A sturdy floor is needed to support the total appliance weight when loaded. The combined weight of a companion appliance should also be considered.

•Clothes may not tumble properly, and automatic sensor cycles may not operate correctly if the appliance is not level.

•Far garage installation, you will need to place the appliance at least 18 inches (45.7 cm) above the floor. The standard pedestal height is 15 inches

INSTALLATION 11

Dimensions and Clearances

The following clearances are recommended for the appliance.

•Additional clearances should be considered for ease of installation and servicing.

•Additional clearances should be considered on all sides of the dryer to reduce noise transfer.

Closet Ventilation Requirements

Closets with doors must have both an upper and lower vent to prevent heat and moisture buildup in the closet. One upper vent opening with a minimum opening of 48 sq. in. (310 cm2) must be installed no lower

than 6 feet above the floor. One lower vent opening with a minimum opening of 24 sq. in. (155 cm2) must be installed no more than one foot above the floor. Install vent grills in the door or cut down the door at the top and bottom to form openings. Louvered doors with equivalent ventilation openings are also acceptable.

NOTE

•There should be at least a little space around the dryer (or any other appliance) to eliminate the transfer of vibration from one appliance to another. If there is enough vibration, it could cause appliances to make noise or come into contact, causing paint damage and further increasing noise.

•No other fuel-burning appliance can be installed in the same closet as a dryer.

aLevel

bLeveling Feet

NOTE

•All four leveling feet must rest solidly on the floor. Gently push on the top corners of the appliance to make sure that the appliance does not rock from corner to corner.

•Adjust the leveling feet only as far as necessary to level the appliance. Extending the leveling feet more than necessary may cause the appliance to vibrate.

•To ensure that the appliance provides optimal drying performance, it must be level. To minimize vibration, noise, and unwanted movement, the floor must be a perfectly level, solid surface.

Adjusting the Leveling Feet

Use an adjustable wrench to turn the leveling feet. Unscrew the legs to raise the appliance or screw in the legs to lower it. Raise or lower with the leveling feet until the appliance is level from side to side

Reversing the Door

WARNING

•Support the door with a stool or box that fits under the door, or have an assistant support the weight of the door.

•Avoid dropping the door.

•Unplug the appliance or turn off power at the main circuit breaker before beginning door reversal.

•Always reverse the door BEFORE stacking the appliance on top of the washer.

Tools Required

•Phillips screwdriver

•Large flat blade screwdriver (recommended for hinge screws if they are tight or your Phillips screwdriver is worn)

•Small flat blade screwdriver (for lifting out parts)

Door Reversal Instructions

The instructions here are for changing the door swing from a right to a left side hinge. If the door has been reversed, and it is necessary to change it back, use care when following these instructions. Some of the illustrations and the left/right references will be reversed, and you will need to read the instructions carefully.

WARNING

•Do not reverse the door while the appliance is stacked on a washing machine.

•Before removing the hinge screws, have an assistant support the weight of the door. The door could fall on the floor due to the weight of the door.

INSTALLATION 15
