ROUTINE MAINTENANCE ________
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.
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.
Important
Dryer produces combustible lint and must be
!exhausted to the outdoors. Every 6 months, inspect
the exhaust ducting and remove any lint buildup.
Suggested Cleaning Schedule
Every Second or Third Load
Clean the lint screen every second or third load. A clogged lint screen will cause poor dryer performance. The lint screen is located behind the lint door in the base of the dryer. Open the lint door, brush the lint off the lint screen, and remove the lint. Inspect lint screen and replace if torn.
Note
The frequency of cleaning the lint screen can best be
!determined from experience at each location.
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.
Steam Models
Clean the steam coil fins. We suggest using compressed air and a vacuum cleaner with brush attachment.
Warning
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 local air conditioning supply house.
90Days
•Remove lint from around basket (tumbler), drive motors, and surrounding areas.
•Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment.
•Clean any lint accumulation in and around both the blower and drive motor casing openings.
Note
To prevent damage, avoid cleaning and/or touching
!
Every 6 Months
Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal exhaust ducting.
Note
The accumulation of lint in the exhaust ductwork can
!create a potential fire hazard.
Do not obstruct the flow of combustion and ventilation air. Check customer furnished back draft dampers in the exhaust ductwork. Inspect and remove any lint accumulation, which can cause the damper to bind or stick.
A back draft damper that is sticking partially closed can result in slow drying and shutdown of heat circuit safety switches or thermostats.
When cleaning the dryer cabinet(s), avoid using harsh abrasives. A product intended for the cleaning of appliances is recommended.
Adjustments ___________________________
7 Days After Installation and Every 6 Months Thereafter
Inspect bolts, nuts, screws, setscrews, grounding connections, and nonpermanent gas connections (unions, shutoff valves, and orifices). Motor and drive belts should be examined. Cracked or seriously frayed belts should be replaced. Tighten loose
Lubrication _____________________________
The motor bearings and under normal/most conditions the basket (tumbler) bearings are permanently lubricated. It is physically possible to relubricate the basket (tumbler) bearings if you choose to do so even though this practice may not be necessary. Use Shell Alvania #2 grease or its equivalent. Generically, this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium thickener and mineral base oil. The basket (tumbler) bearings used in the dryer do not have a grease fitting. Provisions are made in the bearings housing for the addition of grease fitting which can be obtained elsewhere.
