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: REMOVE POWER FROM THE DRYER BEFORE PERFORMING ANY

MAINTENANCE IN THE DRYER

.

NOTE:

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

IMPORTANT:

Dryer produces combustible lint and

must be

exhausted to the outdoors. Every 6

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

CLEAN LINT FROM LINT DRAWER/SCREEN EVERY THIRD OR FOURTH LOAD

.

NOTE:

The frequency of cleaning the lint screens can best be determined from experience at each
location.

WEEKLY

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

WARNING: TO AVOID HAZARD OF ELECTRICAL SHOCK, DISCONTINUE

ELECTRICAL POWER SUPPLY TO THE DRYER
