ROUTINE MAINTENANCE
A. CLEANING
A program 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 FA RICS IS HIGHLY COM USTI LE. THE ACCUMULATION OF
LINT CAN CREATE A POTENTIAL FIRE HAZARD.
KEEP DRYER AREA CLEAR AND FREE FROM COM USTI LE MATERIALS,
GASOLINE, AND OTHER FLAMMA LE VAPORS AND LIQUIDS.
NOTE: Suggested time intervals shown are for average usage which is considered six to eight
operational (running hours per day.
Clean lint drawer and screen every third or fourth load.
NOTE: Frequency can best be determined at each location.
DAILY
Beginning of each work shift.
Clean lint from the drawer and screen. 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.
STEAM DRYERS
Clean steam coil fins using compressed air and a vacuum cleaner with brush attachment.
NOTE: When cleaning steam coil fins, be careful not to bend the fins. If the fins are bent,
straighten by using a fin comb, which is available from local air conditioning supply houses.
90 DAYS
Remove lint from 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 the ignitor/globar probe assembly.
Remove lint accumulation from inside control box and at rear area behind control box.

450325- 1 www.amdry.com 7
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.
B. ADJUSTMENTS
7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER
Inspect bolts, nuts, screws, 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. Complete

INSTALLATION REQUIREMENTS
Installation should be performed by competent technicians in accordance with local and state codes. In the absence
of these codes, the installation must conform to applicable American National Standards: ANSI Z223.1-LATEST
EDITION (National Fuel Gas Code or ANSI/NFPA NO. 70-LATEST EDITION (National Electrical Code or in Canada,
the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91 (Natural Gas or CAN/CGA-
B149.2-M91 (L.P. Gas or LATEST EDITION (for General Installation and Gas Plumbing or Canadian Electrical
Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION (for Electrical Connections .
A. ENCLOSURE, AIR SUPPLY, AND EXHAUST REQUIREMENTS
NOTE: The following information is very brief and general. For a detailed description, refer to the
Installation Manual supplied with the dryer.
Bulkheads and partitions around the dryer should be made of noncombustible materials. Allowances should be
made for the opening and closing of the control door and lint drawer. Also, allowances should be made in the rear for
ease of maintenance. (Refer to the appropriate Installation Manual for recommended distances and minimum
allowances required.
When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler, and exhausts it out of
the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is
inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail switch “fluttering”
problems on gas dryers may result, and you also could have premature motor failure from overheating. The air
supply must be given careful consideration to insure proper performance of each dryer.
IMPORTANT: Make-up air must be provided from a source free of dry cleaning fumes. Make-up air
that is contaminated by dry cleaning fumes will result in irreparable damage to the
motors and other dryer components.
Exhaust ductwork should be designed and installed by a competent technician. Improperly sized ductwork will create
excessive back pressure, which will result in slow drying, increased use of energy, and shutdown of the burner by the
airflow (sail switch, burner hi-limit or lint chamber hi-heat protector thermostat. (Refer to the appropriate Installation
Manual for more details.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A
POTENTIAL FIRE HAZARD.
B. ELECTRICAL AND GAS REQUIREMENTS
It is your responsibility to have all electrical connections made by a properly licensed and competent electrician to
assure that the electrical installation is adequate and conforms to local and state regulations or codes. In the absence
of such codes, all electrical connections, materials, and workmanship must conform to the applicable requirements
of the National Electrical Code ANSI/NFPA NO. 70-LATEST EDITION or in Canada, the Canadian Electrical Codes
