SECTION II

ROUTINE MAINTENANCE

A. CLEANING

A schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer, as well as throughout the duct work 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 air flow. If the guidelines in this section are met, anADC 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 APOTENTIALFIRE HAZARD.

WARNING: KEEP DRYER AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE, and OTHER FLAMMABLE VAPORS and LIQUIDS.

NOTE: REMOVE POWER FROM THE MACHINE 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.

SUGGESTED CLEANING SCHEDULE

EVERY THIRD or FOURTH LOAD

Clean the lint screen. A clogged lint screen will cause poor dryer performance. The lint screen is located in the lint drawer in the base of the dryer. Pull out the lint drawer, brush the lint off the lint screen, and remove the lint. Inspect the lint screen and replace if torn.

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

WEEKLY

Open the hinged panels on each side of the tumbler section and remove any lint accumulation from the tumbler drive motor, drive shafts, gear reducer, drive belts, drive wheels, and drive shaft bearings.

Slide the lint basket all the way out of the dryer and clean any lint accumulation off of the temperature sensor bracket, which is located above the lint basket.

WARNING: TOAVOID THE HAZARD OF ELECTRICAL SHOCK, DISCONTINUE ELECTRICALSUPPLYTO THE DRYER.

5

MONTHLY

Empty the compressed air filter bowl.

Clean any lint accumulation from the gas valve and burner area at the top of the dryer, the fan (impellor/ blower) motor, and the fan (impellor) bearings located in the dryer base.

EVERY 6 MONTHS

STEAM MODELS - clean the steam coil fins. We suggest using compressed air and a vacuum cleaner with brush attachment.

NOTE: When cleaning steam coil fins, be careful not to bend the fins.If fins are bent, straighten by using a fin comb, which is available from any local air conditioning supply house.

Inspect and remove any lint accumulation in customer furnished exhaust duct work system and from the dryers internal exhaust ducting.

NOTE: THEACCUMULATION OF LINT IN THE EXHAUST DUCT WORK CAN CREATE APOTENTIALFIRE HAZARD.

NOTE:DO NOT OBSTRUCT THE FLOW OF COMBUSTION and VENTILATION AIR. CHECK CUSTOMER FURNISHED BACK DRAFT DAMPERS IN THE EXHAUST DUCT WORK. INSPECT and REMOVE ANY LINT ACCUMULATION WHICH CAN CAUSE THE DAMPER TO BIND or STICK.

NOTE: When cleaning the dryer cabinet(s), avoid using harsh abrasives. A product intended for the cleaning of appliances is recommended.

Clean off any lint accumulation on top of the temperature probe and the hi-limitswitch located above the lint basket.
