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.

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 Parts Department at (508) 678-9000.

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 of the skid.

With the skid removed to make it easier to slide the dryer into its final position, slightly lower ALL the 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.

1.Leveling The Dryer

To increase the bearing life, improve efficiency, and provide for better automatic closure of the main door, the basket (tumbler) should be tilted slightly to the rear. Four (4) leveling legs are provided for this purpose and are shipped inside of the top basket (tumbler) 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 wooded skid were removed.

8

B. 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, 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).

1.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.”

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.

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 Requirements 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 as noted in this manual (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 this manual (refer to Exhaust Requirements in Section E).

IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary.

9

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

10.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 should 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 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 (electrical power 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.

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

Dryers may be positioned sidewall to sidewall. 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).

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

D. FRESH AIR SUPPLY REQUIREMENTS

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 make-up 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 (make-up air) must be given careful consideration to assure proper and safe performance of each dryer. An unrestricted source of air (550 cfm [15.58 cmm]) is necessary for each basket (tumbler). An unrestricted air entrance from the outdoors (atmosphere) of a minimum of 2 square feet (0.19 square meters) is required for each dryer. This area must be enlarged if louvers or registers cover the opening.

To compensate for the use of registers or louvers used over the openings, this make-up air must be increased by approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near where exhaust vents exit the building.

10

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 ALL 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, a total make-up air opening of 16 square feet (1.49 square meters) is required. Two (2) openings measuring 2 feet by 4 feet (0.61 meters by 1.23 meters) 16 square feet (1.49 square meters) is 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 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 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.

11

E. EXHAUST REQUIREMENTS

1.General Exhaust Ductwork Information

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: DRYER 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. The shape of the ductwork is not critical so long as the minimum cross-sectional area is provided.

It is suggested that the use of 90º turns be avoided; use 30º or 45º angles instead.

The ductwork 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 ductwork 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 ductwork for periodic inspection and cleaning.

IMPORTANT: When connecting ductwork to the dryer’s top basket (tumbler) exhaust ductwork, be sure that when screws are used they DO NOT restrict the operation (both opening and closing) of the damper.

NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of 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.

To protect the outside end of the horizontal ductwork from the weather, a 90º elbow bent downward should be installed where the exhaust exits the building. If the exhaust ductwork 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, louvers, or caps on the outside opening of the exhaust ductwork.

NOTE: As per the National Fuel Gas Code, “Exhaust ducts for type 2 clothes dryers shall be constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 0.0195-inches (26 gauge [0.05 mm]) thick.”

12

IMPORTANT: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.).

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 into the dryer area through these openings.

If the length of the ductwork run or quantity of elbows used exceeds the specifications noted in this booklet, the cross-sectional area of the ductwork must be increased in proportion to the number of elbows or duct run added.

IMPORTANT: For extended ductwork runs, the cross-sectional area of the duct can only be increased to an extent. For extended ductwork runs, a professional heating, venting, and air conditioning (HVAC) firm should be consulted for proper venting information.

Ductwork 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 6-inches (15.24 cm) 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 (15.24 cm) diameter exhaust duct!!!

2.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 on page 17) or connected commonly (“Y”) together (refer to the illustration on page 18). Both single or common “Y” duct can be rigid or flexible ducting.

13

The illustration below shows the ductwork connection points and what internal ductwork 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 ductwork is included for the top basket (tumbler) (not available from ADC and must be purchased elsewhere). Depending on the external ductwork layout, the installer has the option of the ductwork coming out of the top or the back of the dryer. The ductwork used inside of the dryer, from the blower duct to where it exits the dryer, must be a minimum of 6-inches (15.24 cm) in diameter (30 square inches [193.6 square centimeters] 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 ductwork 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 ductwork joints must be taped to prevent moisture and lint from escaping into the dryer and/or building.

The bottom basket (tumbler) includes a 6-inch (15.24 cm) ductwork, 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.
