absence of these codes, the installation must conform to applicable American National Standards: ANSI Z223.1­LATEST EDITION (National Fuel Gas Code) or ANSI/NFPA NO. 70-LATEST EDITION (National Electrical
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/SETTING UP

Remove protective shipping material (i.e., plastic wrap and/or optional shipping box) 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.

Dryers 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 the ADC factory.

The dryer can be moved to its 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 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 four (4)
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 (1) at each corner of the dryer base. The hex head 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. In the absence of such
codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST
EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.
1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (liquid propane [L.P.] Gas) or LATEST EDITION (for General

C. DRYER ENCLOSURE REQUIREMENTS

Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of
12-inches (30.48 cm), 18-inches (45.72 cm) or more is recommended for ease of installation, maintenance, and
service) above the dryer’s outer top, except along the front of the dryer which may be closed in if desired.

NOTE: Even though a minimum of 12-inches (30.48 cm) above the dryer’s outer top is accept

able, a clearance of 18-inches (45.72 cm) or more is suggested for ease of installation
and service (electrical power connections).

NOTE: When fire sprinkler systems are located above the dryers, a minimum of 12-inches

(30.48 cm) above the dryer’s outer top is required.

NOTE: Allowances must be made for opening the control door.

Dryers may be positioned side wall to side wall. However, allowances must be made for 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 on the previous page (page 10) for details.

NOTE: Air considerations are important for proper and efficient operation.

D. FRESH AIR SUPPLY

Air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An
unrestricted source of 800 cfm (22.65 cmm) is necessary for each dryer. An unrestricted air entrance from the
outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square meters) 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 openings are acceptable. 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 make-up air opening of 12 square feet (3.66 square meters) is required. Two (2) openings
measuring 2 feet by 3 feet (0.61 by 0.92 meters) - 6 square feet (0.56 square meters) - are acceptable. (Refer to
the illustration on page 12.)

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 that is contaminated by dry cleaning solvent fumes will result in
irreparable damage to the motors and other dryer components.

NN

IMPORTANT: Make-up air openings should not be located near duct work exhaust outlets.

If make-up air opening(s) are too close to the exhaust outlet, lint and fumes
may be drawn back into the dryer area through these openings.

NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.

NO
