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 [phone].

IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.

1. DO NOT store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other

appliance.

2. Installation and service must be performed by a qualified installer or service agency.

3. Dryer(s) must be exhausted to the outdoors.

4. 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 rubber materials. Drying in a heated basket (tumbler) may damage
plastics or rubber and also may be a fire hazard.

5. A program should be established for the inspection and cleaning of lint in the heating unit area, exhaust
ductwork, and inside 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.

6. For personal safety, the dryer must be electrically grounded in accordance to 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.

7. UNDER NO CIRCUMSTANCES should the dryer door switches, lint door switch, heat safety circuit

ever be disabled.

WARNING: PERSONAL INJURY OR FIRE COULD RESULT.

8. This dryer is not to be used in the presence of dry cleaning solvents or fumes.

9. 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.

10. DO NOT operate steam dryers with more than 125 PSI (8.61 bars) steam pressure. Excessive steam

pressure can damage steam coil and/or harm personnel.

11. Replace leaking flexible hoses or other steam fixtures immediately. DO NOT operate the dryer with

leaking flexible hoses. PERSONAL INJURY MAY RESULT.

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.

WARNING: YOU MUST DISCONNECT AND LOCKOUT THE ELECTRIC SUPPLY AND

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.
