CHECK YOUR VENT SYSTEM FOR GOOD AIR FLOW

"Maintain good air flow by:

Fire Hazard

Use aheavy metal vent.

Do not use aplastic vent.

Do not use a metal foil vent.

Failure to follow these instructions can result in death

or fire,

p,. =,_

Good air flow

Along with heat, dryers require good air flow to efficiently

dry laundry. Proper venting will reduce your drying times and

improve your energy savings. See Installation Instructions.

The venting system attached to the dryer plays a big role in

good air flow. Blocked or crushed vents as well as improper

venting installation will reduce air flow and dryer performance.

Service calls caused by improper venting are not covered by

the warranty and will be paid by the customer, regardless of

who installed the dryer. To clean or repair venting, contact a

venting specialist.

[] Cleaning your lint screen before each load.

[] Replace plastic or foil vent material with 4" (102 mm)

diameter heavy, rigid vent material.

[] Use the shortest length of vent possible.

[] Use no more than four 90 ° elbows in a vent system;

each bend and curve reduces air flow.

Bet

[] Remove lint and debris from the exhaust hood.

[] Remove lint from the entire length of the vent system at least

every 2 years. When cleaning is complete, be sure to follow

the "Installation Instructions" supplied with your dryer for

final product check.

[] Clear away items from the front of the dryer.

USE SENSOR DRY/AUTOMATIC DRY CYCLES FOR BETTER

FABRIC CARE AND ENERGY SAVINGS

Use the Sensor Dry/Automatic Dry cycles to provide the most energy savings and enhanced fabric care from the dryer. During

Sensor Dry/Automatic Dry cycles, drying air temperature or moisture level is sensed in the load. This sensing occurs throughout

the drying cycle and the dryer shuts off when the load reaches the selected dryness. The Energy Preferred cycle will provide optimal

energy savings.

With Timed Dry, the dryer runs the amount of time set and sometimes results in shrinkage, wrinkling, and static due to over-drying.

Use Timed Dry for the occasional damp load that needs a little more drying time or when using the drying rack.

DRYER CARE

Cleaning the dryer location

eep dryer area clear and free from items that would block the

r flow for proper dryer operation. This includes clearing piles

of laundry in front of the dryer.

Explosion Hazard

Keep flammable materials and vapors, such as

gasoline, away from dryer.

Place dryer at least 18 inches (460 ram) above the floor

for a garage installation.

Failure to do so can result in death, explosion, or fire.

fCleaning the dryer interior

To clean dryer drum

1. Apply a liquid, nonflammable household cleaner to the

stained area of the drum and rub with a soft cloth until

stain is removed.

2. Wipe drum thoroughly with a damp cloth.

3. Tumble a load of clean cloths or towels to dry the drum.

NOTE: Garments that contain loose dyes, such as denim blue

jeans or brightly colored cotton items, may discolor the dryer

interior. These stains are not harmful to your dryer and will

not stain future loads of clothes. Dry these items inside out to

avoid drum staining.

fRemoving accumulated lint

From inside the Dryer Cabinet

Lint should be removed every 2 years, or more often, depending

on dryer usage. Cleaning should be done by a qualified servicer.

From the Exhaust Vent

Lint should be removed every 2 years, or more often, depending

on dryer usage.

FCleaning the lint screen

Every load cleaning

The lint screen is located in the dryer. A screen blocked by lint

can increase drying time.

To clean:

1. Pull the lint screen out of its holder. Roll lint off the screen

with your fingers. Do not rinse or wash screen to remove

lint. Wet lint is hard to remove.

2. Push the lint screen firmly back into place.

iNIPORTANT:

[] Do not run the dryer with the lint screen loose, damaged,

blocked, or missing. Doing so can cause overheating and

damage to both the dryer and fabrics.

[] if lint fails off the screen into the dryer during removal,

check the exhaust hood and remove the lint. See Venting

Requirements.

As needed cleaning

Laundry detergent and fabric softener residue can build up

on the lint screen. This buildup can cause longer drying times

for your clothes, or cause the dryer to stop before your load is

completely dry. The screen is probably clogged if lint fails off

while the screen is in the dryer.

Clean the lint screen with a nylon brush every 6 months,

or more frequently, if it becomes clogged due to a residue

buildup.

To wash:

1. Roll lint off the screen with your fingers.

2. Wet both sides of lint screen with hot water.

3. Wet a nylon brush with hot water and liquid detergent.
