SECTION II

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 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 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.

SUGGESTED INTERVAL	FUNCTION
DAILY	Clean Lint screen. Inspect lint screen and replace if torn.
90 DAYS	Remove lint accumulation from lint chamber thermostats and
	sensors.

WARNING: To avoid the hazard of electrical shock, discontinue electrical supply to dryer.

90 DAYS

Remove lint from the motor air vents and surrounding area.

IMPORTANT: Lint accumulation will restrict internal motor air flow, causing overheating and irreparable damage. Motor failure due to lint accumulation WILL VOID THE MANUFACTURER'S WARRANTY.

120 DAYS	Remove lint from gas burner area with a dusting brush or vacuum cleaner
	attachment.
6 MONTHS	Inspect and remove lint accumulation in customer-furnished
	exhaust duct work system. Inspect exhaust back draft dampers to
	insure they are not binding. Inspect and remove ALL lint
	accumulation from in and around control box area, including coin
	acceptors. Clean lint accumulation from around tumbler wrapper
	area.

WARNING: THE ACCUMULATION OF LINT IN THE EXHAUST DUCT WORK CAN CREATE A POTENTIAL FIRE HAZARD.

IndicatorsNOTE If the dryer is started the L.E.D. display indicator dots are on and there are no outputs heat and/or motor output L.E.D.s are off and the dOOr input L.E.D. is on, the fault is in the Phase 5 coin microprocessor controller computer itself. If the failure was elsewhere i.e., dryers door switch circuit the L.E.D. display would read dOOr if a keyboard entry was attempted. If the L.E.D. display indicators are on and the door L.E.D. input and motor/heat output L.E.D.s are on and the motor and/or heat is not active ON, then the problem is not the door switch circuit or the Phase 5 coin microprocessor controller the problem is else where in the dryer B.
