SECTION VI

ROUTINE MAINTENANCE

A. CLEANING

A program and/or schedule

should be

established for periodic inspection, cleaning, and removal of lint from

various areas of the dryer, as well as throughout the ductwork system. The frequency of cleaning can best be
determined from experience at each location. Maximum operating efficiency is dependent upon proper air
circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, an

ADC

dryer will provide many years of efficient, trouble free, and most importantly, safe operation.

WARNING: LINT FROM MOST FABRICS IS HIGHLY COMBUSTIBLE. THE

ACCUMULATION OF LINT CAN CREATE A POTENTIAL FIRE HAZARD.

WARNING: KEEP DRYER AREA CLEAR AND FREE FROM COMBUSTIBLE

MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND
LIQUIDS.

NOTE:

Suggested time intervals shown are for average usage which is considered six (6) to eight (8)
operational (running) hours per day.

CLEAN THE LINT DRAWER/SCREEN EVERY THIRD OR FOURTH LOAD.

NOTE:

Frequency can best be determined at each location.

IMPORTANT:

Dryer produces combustible lint and

must be

exhausted to the outdoors. Every six

(6) months, inspect the exhaust ducting and remove any lint build up.

SUGGESTED CLEANING SCHEDULE

DAILY

(beginning of each work shift)

1. Clean lint from screen.

2. Inspect lint screen and replace if torn.

WEEKLY

Clean lint accumulation from lint chamber, thermostat, and microprocessor temperature sensor (sensor bracket)
area.

WARNING: TO AVOID THE HAZARD OF ELECTRICAL SHOCK, DISCONTINUE

ELECTRICAL SUPPLY TO THE DRYER
