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 airflow. 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
door/drawer is located just below the loading door of the
dryer. Open the lint door/drawer, brush the lint off the lint
screen, and remove the lint. Inspect lint screen and replace
if torn.
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.
90 Days
Remove lint from around the tumbler, fan blades, 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 the motor(s) casing
opening.
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 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 (lint door/drawer switch,
door switches, sail switch, 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.
