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 and 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. The manufacturer assumes no responsibility for freight claims or damages.

IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.

A. UNPACKING AND SETTING UP

Remove protective shipping material (i.e., plastic wrap and optional shipping box) from dryer.

IMPORTANT: Dryer must be transported and handled in an upright position at ALL times.

NOTE: The key for the top control door, and bottom lint door is located in the information packaged and shipped in the dryers basket (tumbler). This key should be made accessible because it will be needed throughout various phases in the installation of the dryer.

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 base (remove the back panel for access), and two (2) are located in the bottom of the lint chamber. To remove the two (2) bolts located in the lint chamber area, remove the lint door.

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.

To increase bearing life and improve efficiency, the dryer should be tilted slightly to the rear.

The lint coops of ALL model dryers are supported during shipping by a bracket. REMOVE THIS BRACKET BEFORE STARTING THE DRYER.

1.Leveling Dryer

The dryer is equipped with four (4) leveling legs, one (1) at each corner of the base. Two (2) are located at the rear of the dryer base, and two (2) are located in the lint chamber (coop). To increase bearing life and improve efficiency, the dryer should be tilted slightly to the rear.

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.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).

9

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’s outer top; except along the front of the dryer which may be closed if desired.

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

X = 12-inch (30.48 cm) minimum, 24-inches (60.96 cm) is suggested for ease of maintenance.

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

Dryers may be positioned sidewall to sidewall. However, a 1/16” (1.5875 mm) minimum allowance 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 above for details.

10

American Dryer Corp MDG-30 User Manual

D. FRESH AIR SUPPLY REQUIREMENTS

The 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 1-1/2 square feet (0.14 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 2 feet by 3 feet (0.61 meters by 0.91 meters) 6 square feet [0.55 square meters] each opening) are acceptable.

IMPORTANT: Make-up air openings should not be located in an area directly near where exhaust vents exit the building.

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.

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

11

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, and shutdown of the burner by the airflow (sail) switch, burner hi-limit, or lint chamber hi-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.

When possible, it is suggested to provide a separate (single) exhaust duct for each dryer.

CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A POTENTIAL FIRE HAZARD.

CAUTION: DRYER MUST BE EXHAUSTED TO THE OUTDOORS.

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 section area is provided. Single or independent dryer venting is recommended.

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

The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will 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 exhaust duct, 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 90° elbow bent downward should be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it should be protected from the weather by using a 180° turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and the nearest obstruction (i.e., roof or ground level).

IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust ductwork.

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.).
