IMPORTANTINFORMATION
A. RECEIVINGAND 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 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, andALL 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.

Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of
6-inches (15.24 cm) above the dryer’s outer top; except along the front of the dryer which may be closed if
desired.
NOTE: Allowancesmust bemade foropeningthe controldoor.
X = 12-inch (30.48 cm) minimum, 24-inches (60.96 cm) is suggested for ease of maintenance.
NOTE: Airconsiderationsareimportant for properandefficientoperation.
Dryers may be positioned sidewall to sidewall. However, a 1/16” (1.5875 mm) minimum allowance must be
made for the opening and closing of the control door and the lint door. It is suggested that the dryer be positioned
about 2 feet (0.61 meters) 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.

11
D. FRESH AIR SUPPLYREQUIREMENTS
TheAD-20 air supply (make-up air) must be given careful consideration to assure proper performance of each
dryer. An unrestricted source of air is necessary for each dryer. As a general rule, an unrestricted air entrance
from the outdoors (atmosphere) of a minimum of 1/4 square feet (0.023 square meters) is required for each
dryer. If registers or louvers are installed over the openings, then the area must be increased. It is not
necessary to have a separate make-up air opening for each dryer. Common make-up air openings are acceptable.
However, they must be set up in such a manner that the make-up air is distributed equally to the dryers. The
dryer must be installed with provisions for adequate combustion and make-up air supply.
EXAMPLE: For a bank of eight (8) dryers, two (2) unrestricted openings measuring 1 foot by 1
foot (0.31 meters by 0.31 meters), (1 square foot [0.93 square meters]) are
acceptable.
IMPORTANT: Make-up airopenings should notbe locatedin anarea directlynear whereexhaust
ventsexitthebuilding.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitudes or predominantly low pressure areas.
IMPORTANT: Make-up airmustbeprovided from asourcefree ofdrycleaning solventfumes.

E. EXHAUST REQUIREMENTS
DO NOT use a nonmetal flexible vent or a metal vent that is smaller than 4” (10.2 cm) in diameter or exhaust
hoods with magnetic latches.
DO NOT exhaust dryer into a chimney, furnace, cold air vent, attic, crawl space, or any other vent used for
venting.
DO NOT install flexible vent in enclosed walls, ceilings, or floors.
IMPORTANT: ObserveALLgoverning codesandordinances.
Exhaust your dryer to the outside. Moisture and lint indoors may cause:
1. Lint to gather around the dryer where it can be fuel for a fire.
2. Moisture damage to woodwork, furniture, paint, wallpaper, carpet, etc...
3. Housecleaning problems and health problems.
A 4” (10.2 cm) diameter vent is required. Arigid or flexible metal vent must be used. DO NOT use a plastic
or a foil covered vent.
Use a heavy metal vent. DO NOT use a plastic or metal foil vent. A rigid metal vent is recommended to
prevent crushing and kinking. Aflexible metal vent must be fully extended and supported when the dryer is in
its final position. Remove excess flexible vent to avoid sagging and kinking that may result in reduced airflow.
If using an existing exhaust system, clean lint from entire length of system and make exhaust hood is not plugged
with lint. Replace any vinyl or metallized plastic foil vent with rigid metal or flexible metal vent.
Use duct tape to seal ALL joints. DO NOT use screws or other fastening devices that extend into the interior
of the vent to secure vent.
Service check: Back pressure in any exhaust system used must not exceed 0.6 inches (1.49 mb) water column
(W.C.) measured with an incline manometer at the point that exhaust vent connects to the dryer.

13
IMPORTANTVENTINGREMINDERS
1. Ductwork size and installation should be done by a qualified professional.
2. The dryer must be exhausted to the outdoors.
3. Ductwork should be routed as short as possible to the outdoors with as few elbows as possible.
4. Avoid 90° turns, use 30° or 45° turns instead.
5. The inside of the ductwork should be as smooth as possible with no projections from sheet metal screws.
Ducts added should overlap the duct to which it is to be connected.
6. ALL ducts should be taped to prevent moisture and lint from escaping into the building.
7. Inspection or clean out doors should be installed throughout strategic points in the ductwork for periodic
inspection and cleaning.
8. Wherever the ductwork passes through combustible materials, the opening must be 2-inches (5.08 cm)
larger than the duct (all the way around). The duct must be centered within this opening.
9. The outside of the ductworkmust beprotected from the weather. A90° elbow must be used for horizontal
run and when vertically through a roof by using a 180° turn to point the opening downward. The distance
between the exhaust duct and the nearest obstruction (i.e., roof or ground) must be twice the diameter of
the duct.
10. DO NOT use screens, louvers, or caps on the outside opening of the exhaust ductwork.
11. Exhaust back pressure measured by a manometer at the dryer exhaust duct area must be no less than 0
and must not exceed 0.6 inches (1.49 mb) of water column (W.C.).
WARNING: DRYER MUST NEVERBE OPERATEDWITHOUTTHELINTFILTER/SCREEN
IN PLACE, EVEN IFAN EXTERNALLINT COLLECTION SYSTEM IS USED.
12. Exhaust ductwork outlets should not be located in an area directly where the make-up air openings are
located.
