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.

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 ALLoccupants.

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 dryer, 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 solvents 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 may be a fire hazard.

7. A program should be established for the inspection and cleaning of lint in the burner area, exhaust ductwork,

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 ductwork 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 Electrical Code ANSI/NFPA NO. 70-LATEST EDITION or in Canada, the Canadian Electrical

Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION.

NOTE: Failure to do so will VOID THE WARRANTY.

9. UNDER NO CIRCUMSTANCES should the dryer door switch, lint drawer switch, or the heat circuit

devices 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 completed can

create a fire hazard.

12. READ AND FOLLOW ALL CAUTION AND DIRECTION LABELS ATTACHED TO THE

DRYER.

13. For safety, proper operation, and optimum performance, the dryer must not be operated with a load less

than sixty-six percent (66%), 79 lbs (35.83 kg) of its rated capacity.

THE GAS SUPPLY OR THE STEAM SUPPLY BEFORE ANY COVERS OR

GUARDS ARE REMOVED FROM THE MACHINE TO ALLOW ACCESS
