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.
90 Days
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
ignitor/flame-probe assembly.
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 V-belts when necessary. Complete
operational check of controls and valves. Complete
operational check of all safety devices (door switches, lint
drawer switch, sail switch, burner and hi-limit thermostats).
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.
