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.

SECTION III
INSTALLATION PROCEDURES
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: National
Fuel Gas Code ANSI.Z223.1-LATEST EDITION and/or National Electric Code ANSI/NFPA NO. 70-LATEST
EDITION.
A. LOCATION REQUIREMENTS
Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such
codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1-LATEST
EDITION.
1. The dryer must be installed on a sound level floor capable of supporting its weight. It is recommended that
carpeting be removed from the floor area that the dryer is to rest on.
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
(refer to Exhaust Requirements in Section E).
IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be
necessary.
9
B. UNPACKING/SETTING UP
Remove protective shipping material (i.e., plastic wrap, and 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 with or without the skid attached. To un-skid the dryer, locate and
remove the four (4) bolts securing the base of the dryer to the wooden skid. Two (2) are located at the rear base
(remove the back panel for access), and two (2) are located in the bottom of the lint chamber. To remove the two
(2) bolts located in the lint chamber area, remove lint drawer completely. (Refer to page 40 for lint drawer
removal instructions.) Once the bolts are removed and the lint drawer is reinserted, slide the dryer off of the skid.
With the skid removed, to make it easier to slide the dryer into its final position, slightly lower ALL four leveling
legs, so that the dryer will slide on the legs instead of the base frame.
1. LEVELING DRYER
The dryer is equipped with four (4) leveling legs, one at each corner of the dryer base. Two (2) are located at
the rear of the dryer base, and two (2) are located in the lint chamber. To increase bearing life and improve
efficiency, the dryer should be tilted slightly to the rear.
10
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of
twelve (12) inches (18 inches or more is recommended for ease of installation, maintenance , and service) above
the dryer outer top, except along the front of the dryer which may be partially closed in if desired. 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. The bulkhead facing must not be closed in all the way to the top of
the dryer. A one (1) inch clearance is required.
NOTE: Allowances must be made for opening the control door.
Dryers may positioned side wall to side wall. However, a 1/16" minimum allowance must be made for
opening and closing of the control door and the lint door. It is suggested that the dryer be positioned about
two (2) feet away from the nearest obstruction for ease of installation, maintenance, and service (to be
measured from the back guard. (Refer to the illustration above for details.)
NOTE: Air considerations are important for proper and efficient operation.
11
IMPORTANT : Even though a minimum of only 12 inches is required, 18 inches or more is
suggested. The additional clearance is advantageous for ease of installation
and service.
IMPORTANT : When fire sprinkler systems are located above the dryers, a minimum of
18 inches above the dryer console (module) is required. Dryers may be
positioned side wall to side wall however, a 1/16" minimum allowance is
required between dryers (or wall) for ease of installation and maintenance.
Allowances must be made for the opening and closings of the control door
and the lint door.
D. FRESH AIR SUPPLY
When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and
exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the
makeup air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail
switch "fluttering" problems may result, as well as premature motor failure from overheating.
Air supply (makeup air) must be given careful consideration to assure proper performance of each dryer. An
unrestricted source of air is necessary for each dryer. An air flow of 1,700 cfm (cubic feet per minute) must be
supplied to each gas and electric dryer and 2,500 cfm (cubic feet per minute) must be supplied to each steam
dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 2-1/2
square feet is required for each dryer.
