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 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 or 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.

SECTION III
INSTALLATION PROCEDURES
Installation should be performed by qualified professionals in accordance with local and state codes. In the
absence of these codes, installation must conform to applicable AMERICAN NATIONAL STANDARDS:
ANSI Z223.1-LATEST EDITION (NATIONAL FUEL CODE)
or
ANSI/NFPA No. 70-LATEST EDITION (NATIONAL ELECTRIC CODE)
or in Canada, the installation must conform to applicable CANADIAN STANDARDS:
CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION
(for GENERAL INSTALLATION and GAS PLUMBING)
or
CANADIAN ELECTRICAL CODES PARTS 1 & 2 CSA C22.1-1990 or LATEST EDITION
(for ELECTRICAL CONNECTIONS).
A. Unpacking/Setup
Remove stretch wrap protective cover, shipping corners, and top cover from dryer.
NOTE: The access keys for the service doors are included in the information packet shipped in the
basket (tumbler). These keys should be removed and put in a safe place yet made
accessible because some will be needed throughout various phases in the installation of the
dryer.
Coin dryer’s are shipped with a coin box and coin box faceplate only. The coin box lock is not included and
must be purchased elsewhere or the lock can be ordered as a parts order from ADC factory.
The dryer can be moved to it’s final location while still attached to the skid or with the skid removed. To unskid
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 of the base, and two (2) are located in the front. Once the bolts are removed, slide the dryer
off the skid.
With the skid removed, to make it easier to slide the dryer into its final position, slightly lower all leveling legs so
that the dryer will slide on the legs instead of the base frame. The dryer is equipped with four (4) leveling legs,
one at each corner of the dryer base. The slotted adjustment bolts for the two (2) front leveling legs are located
directly behind the lower access door, and the rear two (2) adjustments are directly behind the lower rear back
(guard) panel.
B. Location Of The Dryer
Before installing the dryer, be sure the location conforms to local codes and ordinances.
The dryer must be installed on a sound, level floor capable of supporting it’s weight. It is recommended that
carpeting be removed from the floor are on which the dryer is to rest.
8
Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned
approximately 2 feet away from the nearest obstruction, i.e., wall, for ease of installation, maintenance, and
service.
1. Leveling The Dryer
To increase bearing life, improve efficiency, and provide for better automatic closure of main doors, the tumbler
should be tilted slightly to the rear. Four (4) leveling legs are provided for this purpose and are shipped inside the
top tumbler (basket) and must be installed at the time of installation. A leveling leg must be screwed into the
bottom of the dryer base at each corner area where the bolts used to secure the dryer to the wooden skid were
removed.
C. Dryer Enclosure Requirements
Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of
6-inches above the dryer outer top, except along the front of the dryer which may be closed in if desired.
NOTE: Even though a minimum of 6-inches above the dryer outer top is acceptable, a clearance of
18-inches (or more) is suggested for ease of installation and service (power electrical connections).
NOTE: When fire sprinkler systems are located above the dryers, a minimum of 12-inches above the
dryer outer top is required.
9
D. Fresh Air Supply
Air supply (make-up air) must be given careful consideration to assure proper and safe performance of each
dryer. An unrestricted source of air of 550 cfm is necessary for each tumbler. An unrestricted air entrace from
the outdoors (atmosphere) of a minimum of 2 square feet is required for each dryer. This area must be enlarged
if louvers or registers cover the opening. It is not necessary to have a separate make-up air opening for each
dryer. Common make-up air is distributed equally to the dryers. However, they must be set up in such a manner
that the make-up air is distributed equally to the dryers. For example, for a bank of eight (8) dryers, a total makeup air opening of 16 square feet is required. Two (2) openings 2’ by 4’ (16 square feet) are acceptable.
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 air must be provided from a source free of dry cleaning solvent fumes.
Make-up air contaminated by dry cleaning solvents will result in irreparable damage to
motors and dryer components.
IMPORTANT: Make-up air openings should not be located near duct work exhaust outlets. If the
make-up air opening(s) are too close to the exhaust outlet, lint and fumes may be drawn
back into the dryer through these openings.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
10
E. Exhaust Requirements
General Information
Exhaust duct work should be designed and installed by a competent technician. Improperly sized duct work will
create excessive back pressure which results in slow drying, increased use of energy, and shutdown of the burner
by airflow (sail) switch, burner hi-limit, or lint chamber hi-heat protector thermostat.
Where possible, it is suggested that a sperate (single) exhaust duct for each dryer/tumbler be provided.
CAUTION: IMPROPERLY SIZED or INSTALLED EXHAUST DUCT WORK CAN
CREATE A POTENTIAL FIRE HAZARD.
CAUTION: DRYER MUST BE VENTED TO THE OUTDOORS.
The exhaust duct work should be laid out in such a way that the duct travels as directly as possible to the
outdoors with as few turns as possible. The shape of the duct work is not critical so long as the minimum crosssectional area is provided.
It is suggested that the use of 90º turns in ducting be avoided; use 30º or 45º angles instead.
The duct work should be smooth inside with no projections from the sheet metal screws or other obstructions
which collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is connected.
ALL duct work joints must be taped to prevent moisture and lint from escaping into the building. Additionally,
inspection doors should be installed at strategic points in the exhaust duct work for periodic inspection and
cleaning.
The duct work material must meet applicable National, State, and Local codes, or in Canada, the duct work
material must meet applicable Canadian National, Provincial, and Local codes.
IMPORTANT: When connecting duct work to the dryer’s top basket (tumbler) exhaust duct work, be
sure that when screws are used they do not restrict the operation (both opening and
closing) of the damper.
NOTE: When the exhaust duct passes through a wall, ceiling, or roof made of combustible materials, the
opening must be 2-inches larger (all the way around) than the duct. The duct must be centered
within this opening.
To protect the outside end of horizontal duct work from the weather, a 90º elbow bent downward should be
installed where the exhaust exits the building. If the exhaust duct work travels vertically up through the roof, it
should be protected from the weather by using a 180º turn to point the opening downward. In either case, allow
at least twice the diameter of the duct between the duct opening and nearest obstruction.
IMPORTANT: DO NOT use screens or caps on the outside opening of exhaust duct work.
11
IMPORTANT: Exhaust back pressure measured by a manometer at the dryer exhaust duct area
must not exceed 0.3 inches of water column.
NOTE: Careful consideration should be given to where the exhaust duct is located in relation to the
make-up air openings. If make-up air opening is too close to exhaust outlet, lint and fumes
will be drawn back in to the dryer area through these openings.
If the length of the duct work run or quantity of elbows used exceeds the specifications noted in this booklet, the
cross-sectional area of the duct work must be increased in proportion to the number of elbows or duct run added.
IMPORTANT: For extended duct work runs, the cross-sectional area of the duct can only be
increased to an extent. For extended duct work runs, a professional HVAC firm
should be consulted for proper venting information.
Duct work should be laid out in such a manner where allowances are made at the rear of the dryer for removal
of rear service panels/guards.
IMPORTANT: Even though the dryer’s exhaust outlet size is six (6) inches in diameter (at both the
top basket [tumbler] damper duct and the bottom basket [tumbler] elbow where it
leaves the dryer), the minimum connection at the point of exit from the dryer
in ALL cases MUST BE increased. The amount of increase in diameter will
depend on the venting application/layout as described further in this manual.
IMPORTANT: UNDER NO CIRCUMSTANCES CAN THE DRYER BE VENTED TO
THE OUTDOORS USING A 6-INCH DIAMETER EXHAUST DUCT!!!
1. Exhaust Connections of Top and Bottom Baskets (Tumblers)
There is no common venting connection provided with the dryer. Each basket (tumbler) exhaust duct is provided
with its own back draft damper. Each basket (tumbler) can be exhausted directly outdoors independently (refer
to the illustration [MAN2114] on page 16) or connected commonly (“Y”) together (refer to the illustration
[MAN2113] on page 17). Both single or common “Y” duct can be rigid or flexible ducting.
12
The illustration below shows the duct work connection points and what internal duct work is included in the
dryer.
The exhaust connection at the TOP basket (tumbler) must be made at the blower duct inside the cabinet. No
internal duct work is included for the TOP basket/tumbler. (Not available from ADC and must be
purchased elsewhere). Depending on the external duct work layout, the installer has the option of the duct
work coming out of the top of the back of the dryer. The duck work used inside of the dryer, from the blower
duct to where it exits the dryer, must be a minimum of 6-inches in diameter (30 square inches cross-sectional
area). At this point (where the internal ducting ends) the diameter must be increased to meet the application
as described further in this manual.
IMPORTANT: When connecting duct work to the top basket (tumbler) exhaust duct, be sure that
when screws are used they do not restrict the operation (both opening and closing)
of the damper.
IMPORTANT: ALL duct work joints must be taped to prevent moisture and lint from escaping
into the dryer and/or building.
The BOTTOM basket (tumbler) includes 6-inch duct work which extends from the dryer blower duct to the
lower back guard area. At this point the diameter must be increased to meet the application as described
further in this manual.
