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.

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: ANSI Z223.1-LATEST 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 (Liquid Propane [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.

For more effective automatic door closure and better tumbling action (and improved efficiency), the dryer should be tilted slightly to the rear.

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 (L.P. Gas) or LATEST EDITION (for General Installation and Gas Plumbing).

The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be removed from the floor area that the dryer is to rest on.

IMPORTANT: “The dryer must be installed on noncombustible floors only.”

112144-46 www.adclaundry.com 11

Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately 2 feet (0.61 meters) away from the nearest obstruction, i.e., wall, for ease of installation, maintenance, and service.

The dryer must be installed with a proper exhaust duct connection to the outside.

The dryer must be installed with provisions for adequate combustion and make-up air supply.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6

months, inspect the exhaust ducting and remove any lint build up.

IMPORTANT: Dryer must be installed in a location/environment, which the ambient

temperature remains between 40º F (4.44º C) and 130º F (54.44º C).

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) 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 12-inches (30.48 cm) above the dryer outer top is acceptable, a

clearance of 18-inches (45.72 cm) 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 (30.48 cm)

above the dryer outer top is required.

12 American Dryer Corp. 112144-46

D. FRESH AIR SUPPLY REQUIREMENTS

This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the national installation regulations.

Air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An unrestricted source of 400 cfm (11.3 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 (1.15 square meters) is required. Two (2) openings measuring 2 feet by 3 feet (0.61 meters by 0.91 meters) 6 square feet (0.56 square meters) are acceptable. The dryer must be installed with provisions for adequate combustion and make-up air supply.

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.

IMPORTANT: Make-up air openings should not be located near ductwork exhaust outlets. If

make-up air openings 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.

112144-46 www.adclaundry.com 13

E. EXHAUST REQUIREMENTS

Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure, which results in slow drying, increased use of energy, overheating of the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats. The dryer must be installed with a proper exhaust duct connection to the outside.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.

CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE

A POTENTIAL FIRE HAZARD.

IMPORTANT: It is recommended that exhaust or booster fans not be used in the exhaust ductwork

system.

The exhaust ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns as possible. When single dryer (10-inches [25.4 cm]) vertical venting is used, the ductwork from the dryer to the outside exhaust outlet must not exceed 35 feet (10.67 meters) or for 10-inches (25.4 cm) horizontal 10 feet (3.05 meters). In the case of multiple (common) dryer venting, the distance from the last dryer to the outside exhaust outlet must not exceed 15 feet (4.57 meters). The shape of the exhaust ductwork is not critical so long as the minimum cross-sectional area is provided.

It is suggested that the use of 90° turns in ducting be avoided; use 30° or 45° angles instead. Excluding basket (tumbler)/dryer elbow connections or elbows used for outside protection from the weather, no more than two (2) elbows should be used in the exhaust duct run. If more than two (2) elbows are used the cross section area of the ductwork must be increased in proportion to the number of elbows added.

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 or connected to a common duct. Both single or common ductwork can be rigid ducting or flexible ducting. For common connections, a kit (ADC Part No. 882035) is available from the factory and includes the necessary flex ducting, elbows, and “Y” assembly, etc., to join the top and bottom exhausts together.

NOTE: THE FLEXIBLE EXHAUST DUCT KIT IS NOT RECOMMENDED FOR STEAM

DRYERS.

ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.

IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust

duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) water column (W.C.) when both baskets (tumblers) are operating.

NOTE: Common exhaust connections of top and bottom baskets (tumblers) should be installed in

such a manner that the back guards can be removed easily for servicing.
