IMPORTANT INFORMATION
A. RECEIVING and HANDLING
The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover (or
optional box) as a means of preventing damage in transit. Upon delivery, the dryer and/or packaging, and wooden
skid should be visually inspected for shipping damage. If any damage whatsoever is noticed, inspect further
before delivering carrier leaves.
Dryers damaged in shipment:
1. ALL dryers should be inspected upon receipt and before they are signed for.
2. If there is suspected damage or actual damage, the trucker's receipt should be so noted.
3. If the dryer is damaged beyond repair, it should be refused. Those dryers which were not damaged in a
damaged shipment should be accepted, but the number received and the number refused must be noted on
the receipt.
4. If you determine that the dryer was damaged after the trucker has left your location, you should call the
delivering carrier's freight terminal immediately and file a claim. The freight company considers this concealed
damage. This type of freight claim is very difficult to get paid and becomes extremely difficult when more
than a day or two passes after the freight was delivered. It is your responsibility to file freight claims. Dryer/
parts damaged in transit cannot be claimed under warranty.
5. Freight claims are the responsibility of the consignee, and ALL claims must be filed at the receiving end.
ADC assumes no responsibility for freight claims or damages.
6. If you need assistance in handling the situation, please contact the ADC Traffic Manager at (508) 678-9000.
IMPORTANT : The dryer must be transported and handled in an upright position at all times.

B. SAFETY PRECAUTIONS
WARNING : For your safety, the information in this manual must be followed to minimize the risk of
fire or explosion or to prevent property damage, personal injury, or loss of life.
WARNING: The dryer must never be operated with any of the back guards, outer tops, or
service panels removed. PERSONAL INJURY or FIRE COULD RESULT.
1. DO NOT store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other
appliance.
2. Purchaser/user should consult the local gas supplier for proper instructions to be followed in the event the
user smells gas. The instructions should be posted in a prominent location.
3. WHAT TO DO IF YOU SMELL GAS...
a. DO NOT try to light any appliance.
b. DO NOT touch any electrical switch.
c. DO NOT use any phone in your building.
d. Clear the room, building, or area of ALL occupants.
e. IMMEDIATELY call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.
f. If you cannot reach your gas supplier, call the fire department.
4. Installation and service must be performed by a qualified installer, service agency, or gas supplier.
5. Dryer(s) must be exhausted to the outdoors.
6. Although ADC produces a very versatile machine, there are some articles that, due to fabric composition
or cleaning method, should not be dried in it.
WARNING : Dry only water-washed fabrics. DO NOT dry articles spotted or washed in dry cleaning
solvents, a combustible detergent, or "all purpose" cleaner.
EXPLOSION COULD RESULT.
WARNING : DO NOT dry rags or articles coated or contaminated with gasoline, kerosene, oil,
paint, or wax.
EXPLOSION COULD RESULT.
WARNING : DO NOT dry mop heads. Contamination by wax or flammable solvent will create a
fire hazard.
WARNING : DO NOT use heat for drying articles that contain plastic, foam, sponge rubber, or
similarly textured rubberlike materials. Drying in a heated basket (tumbler) may damage
plastics or rubber and also may be a fire hazard.
4
7. A program should be established for the inspection and cleaning of lint in the burner area, exhaust duct
work, and area around the back of the dryer. The frequency of inspection and cleaning can best be
determined from experience at each location.
WARNING : The collection of lint in the burner area and exhaust duct work can create a potential fire
hazard.
8. For personal safety, the dryer must be electrically grounded in accordance with local codes and/or the
NATIONAL ELECTRIC CODE ANSI/NFPA NO. 70-LATEST EDITION.
NOTE: Failure to do so will VOID THE WARRANTY.
9. UNDER NO CIRCUMSTANCES should the dryer door switches, the lint drawer switch, or the heat
safety circuit ever be disabled.
WARNING: PERSONAL INJURY or FIRE COULD RESULT.
10. This dryer is not to be used in the presence of dry cleaning solvents or fumes.
11. Remove articles from the dryer as soon as the drying cycle has been completed.
WARNING : Articles left in the dryer after the drying and cooling cycles have been complete can
create a fire hazard.
12. DO NOT operate steam dryers with more than 125 PSI steam pressure. Excessive steam pressure can
damage the steam coil and/or harm personnel.
13. Replace leaking flexible steam hoses or other fixtures immediately. DO NOT operate the dryer with leaking
flexible hoses. PERSONAL INJURY MAY RESULT.
14. READ and FOLLOW ALL CAUTION and DIRECTION LABELS ATTACHED TO THE DRYER.
WARNING: YOU MUST DISCONNECT and LOCKOUT THE ELECTRIC SUPPLY and
THE GAS SUPPLY or THE STEAM SUPPLY BEFORE ANY COVERS or
GUARDS ARE REMOVED FROM THE MACHINE TO ALLOW ACCESS
FOR CLEANING, ADJUSTING, INSTALLATION, or TESTING OF ANY
EQUIPMENT per OSHA (Occupational Safety and Health Administration)
STANDARDS.

2. The dryer must not be installed or stored in an area where it will be exposed to water and/or weather.
3. The dryer is for use in noncombustible locations.
4. Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply in
Section D).
5. Clearance provisions must be made from combustible construction as noted in this manual (refer to Dryer
Enclosure Requirements in Section C).
6. Provisions must be made for adequate clearances for servicing and for operation as noted in this manual
(refer to Dryer Enclosure Requirements in Section C).
7. Dryer must be exhausted to the outdoors (refer to Exhaust Requirements in Section E).
8. Dryer must be located in an area where correct exhaust venting can be achieved as noted in the manual

10
B. UNPACKING/SETTING UP
Remove protective shipping material (i.e., plastic wrap, and/or optional shipping box) from dryer.
IMPORTANT: Dryer must be transported and handled in an upright position at all times.
The dryer can be moved to its final location while still attached to the skid or with the skid
removed. To un-skid the dryer, locate and remove the four (4) lag bolts securing the base of the dryer to the
wooden skid. Two (2) are at the rear base, and two (2) are located in the bottom of the lint chamber. To remove
the two (2) lag bolts located in the lint chamber area, remove the lint drawer and the three (3) Phillips head
screws securing the lint door in place.
1. Leveling Dryer
a. To level the dryer, place 4-inch metal shims or other suitable material under the base pads. It is suggested
that the dryer be tilted slightly to the rear (refer to the illustration above).
b. The V-belts are disconnected from the tumbler drive motor for shipping. Reconnect V-belts before
starting the dryer.
11
2. If more headroom is needed when moving the dryer into position, the top console (module) may be removed.
a. To Remove Top Console (module)...
1) Disconnect the ground wire (A in the illustration below) located at the rear upper left corner of the
dryer.
2) Remove the eight (8) sets of nuts and washers (B in the illustration below) holding the console
(module) to the base.
3) Disconnect the white plug (C in the illustration below) connector located on the top of the rear electric

5) Lift the console (module) off of the dryer base.
IMPORTANT : The dryer must be transported and handled in an upright position at all times.
12
C. DRYER ENCLOSURE REQUIREMENTS
Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned
approximately two (2) feet (24-inches) from the nearest obstruction (i.e., wall) for ease of installation,
maintenance, and service. Bulkheads and partitions should be made from noncombustible materials. The
clearance between the bulkhead header and the dryer must be a minimum of four (4) inches and must not
extend more than four (4) inches to the rear of the front. A 2-inch clearance is required between the bulkhead
facing and the top of the dryer.
