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 to eight operational
(running) hours per day.
IMPORTANT: Dryers produce combustible lint and must
be exhausted to the outdoors. Every six months, inspect
the exhaust ducting and remove any lint buildup.
Suggested Cleaning Schedule
Every Third or Fourth Load
Clean the lint drawer screen every third or fourth load. A
clogged lint screen will cause poor dryer performance.
Inspect the 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 the lint chamber, thermostat,
and microprocessor temperature sensor (sensor bracket)
area.
!
WARNING
To avoid the hazard of electrical shock, discontinue
electrical supply to the dryer.
90 Days
Remove lint from around tumbler, drive motor, and
surrounding areas.
Remove lint from the 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 Six 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.
