Routine Maintenance - American Dryer Corp. AD-25V Installation Manual

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, the 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 6 to 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 Third or Fourth Load
Clean the lint screen every third or fourth load. A clogged lint
screen will cause poor dryer performance. The lint screen is
located in a drawer below the main door. Open the lint drawer,
brush or vacuum the lint off the lint screen, and remove the
lint. Inspect the lint screen and replace it 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.
Steam Dryers
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
houses.

90 Days
Inspect and remove lint accumulation in customer furnished
exhaust ductwork system and from the dryer's internal
exhaust ducting.
The accumulation of lint in the exhaust ductwork can
create a potential fire hazard.
Do not obstruct the flow of combustion and ventilation
air.
Inspect and remove any lint accumulation, which can
cause the back draft damper to bind or stick.
NOTE: 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, idler bearings, and under normal/most
conditions the tumbler bearings are permanently lubricated.
It is physically possible to relubricate the tumbler bearings if
you choose to do so even though this practice is not
necessary. Use Shell Alvania #2 grease or its equivalent.
The tumbler bearings used in the dryer do not have a grease
fitting. Provisions are made in the bearing housing for the
addition of a grease fitting, which can be obtained elsewhere,
or from the manufacturer by ordering kit P/N 882159 (includes
two fittings).
