MAINTENANCE
CLEANING
A program and/or schedule should be estab­
lished for periodic inspection, cleaning and
removal of lint from various areas of the dryer,
as well as throughout the duct work system.
The frequency of cleaning can best be deter­
mined from experience at each location. Maxi­
mum operating efficiency is dependent upon
proper air circulation. The accumulation of lint
can restrict this air flow.
WARNING: LINT FROM MOST FABRICS IS
HIGHLY COMBUSTIBLE. THE ACCUMULA­
TION OF LINT CAN CREATE A POTENTIAL
FIRE HAZARD.
WARNING: KEEP DRYER AREA CLEAR and
FREE FROM COMBUSTIBLE MATERIALS,
GASOLINE and OTHER FLAMMABLE VA­
PORS and LIQUIDS.
NOTE: Suggested time intervals shown are for
average usage which is considered six (6) to
eight (8) operational (running) hours per day.
CLEAN LINT FROM LINT DRAWER/SCREEN
EVERY THIRD or FOURTH LOAD.
NOTE: Frequency can best be determined at
each location.
DAILY (beginning of each work shift)
Inspect lint screen and replace if torn.
WEEKLY
Clean the lint accumulation from lint chamber,
thermostat, and microprocessor temperature
sensor (sensor bracket) area.
WARNING: TO AVOID THE HAZARD OF
ELECTRICAL SHOCK, DISCONNECT ELEC­
TRICAL SUPPLY TO THE DRYER.
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.
NOTE: To prevent damage, avoid cleaning and/
or touching ignitor/flame-probe assembly.
Remove lint accumulation from inside control
box and at rear area behind control box.
Impellor (fan/blower) shaft bearings should be
lubricated. Use a #3 grease or equivalent.
WARNING: THE ACCUMULATION OF LINT IN
THE EXHAUST DUCT WORK CAN CREATE A
POTENTIAL FIRE HAZARD.
WARNING: DO NOT OBSTRUCT THE FLOW
OF COMBUSTION and VENTILATION AIR.
CHECK CUSTOMER FURNISHED BACK
DRAFT DAMPERS IN EXHAUST DUCT
WORK. INSPECT and REMOVE ANY LINT
ACCUMULATION WHICH CAN CAUSE
DAMPER TO BIND OR STICK.
NOTE: A back draft damper that is sticking
partially closed can result in slow drying and
shudown of the heat circuit safety switches or
thermostats.
NOTE: When cleaning 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 (bearing set screws),
non-permanent gas connections (unions, shut­
off valves, orifices, and grounding connections).
Motor and drive belts should be examined.
Cracked or seriously frayed belts should be
replaced. Tighten loose V-belts when neces­
sary. Complete operational check of controls
and valves. Complete operational check of
ALL
safety devices (door switch, lint drawer switch,
sail switch, burner and hi-limit thermostats).
LUBRICATION
Impellor (fan/blower) shaft bearings should be
lubricated every three (3) months. Use a #3
grease or equivalent.
The motor bearings, idler bearings, and tumbler
bearings are
permanently lubricated. NO
LUBRICATION IS NECESSARY.
