Exhaust and Dryer Maintenance Cleaning the Lint Screen

1. After one year of use, the interior and complete exhaustsystem of the dryer should be examined and cleaned ifnecessary.

2. Before one year of use, when drying performance hasbecome unsatisfactory, please examine and clean theexhaust duct for better drying performance.

3. Check the weather hoods frequently to ensure the dampers are moving freely, that the dampers are not pushed in and that nothing has been set against thedampers.

4. A qualified service person or company should be usedto perform this maintenance.

5. A Flexible Metal Vent Kit, available at extra cost, can be used to exhaust the dryer when it is placed in hard toreach places. This Kit comes in two pieces, one of which is attached to the dryer and the other is attachedto the wall exhaust outlet. Following attachment of thetwo separate pieces to the dryer and the wall, the dryermay be returned to its final position, after which the two pieces themselves can be connected.

7. Ordinarily, the dryer drum will need no care. Wipe theexterior of the dryer as required, and always wipe theexterior of the dryer in the event any detergent, bleach,or other washing products is spilled on the dryer.

8. Clean the control panel with a damp cloth as necessary. Warning: spray pre-wash products maydamage the finish of the control panel.

9. Please clean the lint filter either before drying each load or after drying each load.

10. Always make sure the lint filter is clean before starting a new load, because a clogged lint filter mayincrease drying times.

11. Annually remove the lint filter and attach it to the vacuum duct. See item #2 above.

12. Please note that the wiring diagram is provided insidethe dryer control hood. Label all wires prior todisconnection when servicing the dryer, becausewiring errors can cause serious injury to you and yourdryer.

1. Clean the lint filter either before drying each loador after drying each load. Always make sure thelint filter is clean before starting a new load,because a clogged lint filter may increase dryingtimes.

2. To clean, pull the lint screen straight up and rollany lint off the screen with your fingers. Do not rinse or wash screen to remove lint. Pushthe lint screen firmly back into place.

3. Always ensure the lint screen is firmly securedbefore running the dryer. Running the dryer witha loose lint screen may cause overheating anddamage to the dryer and articles being dried.

4. Some articles of clothing may shed more lint thanothers (towels for example), causing the lintscreen to fill rapidly. Remove lint from the lintscreen before and after drying these articles, suchas new towels.

5. In the event lint falls off of the lint screen andinto the dryer during removal, inspect the exhausthood and remove any lint.

6. Laundry detergent and fabric softener residue canbuild up on the lint screen, causing longer dryingtimes. The screen is likely blocked if lint falls offthe screen. In order to prevent this type of buildup, and help ensure proper operation of yourdryer, clean the lint screen with a nylon brushevery six months or, if necessary, more frequently. The lint filter can also be washed asfollows:

a) After rolling the lint off of the screen with yourfingers, wet both sides of the screen with hot orwarm water.

b) Wet a nylon brush with hot water and liquiddetergent and scrub the lint screen with the brushto remove the buildup of detergent and fabricsoftener.

c) After the residue has been removed, rinse screenwith hot water.

d) After drying the lint screen with a clean towel,firmly replace the lint screen in your dryer.

WARNING• Disconnect the dryer’s electric power

prior to any cleaning or maintenance.

• Failure to do so can result in fire or electric shock.
