Important Information
A. RECETVTNG AND HANDLING
The dryer is shipped in a protective wrap cover as a means of preventing damage in transit Upon
delivery, the dryer and protective packaging should be visually inspected for shipping damage. If any
damage whatsoever is noticed, inspect further before delivering carrier leaves.
Dryers Damaged in Shipment
1. The dryer should be inspected upon receipt and before it is 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 number refused must be noted
on the receipt.
S

f
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. Dryers/parts damaged in transit cannot be claimed under warranty.
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.
5. If you need assistance in handling the situation, please contact the traffic manager at American Dryer
Corp. (ADC) at (508) 678-9000.
IMPORTANT; The dryer tumbler section must be transported and handled in an upright
position at all times.
