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.

14

a.Connecting Both Top Baskets (Tumblers) and Bottom Baskets (Tumblers) Together

Both the top basket (tumbler) and the bottom basket (tumbler) can “Y” together to form one (1) connection point. The bottom basket (tumbler) already includes a 6-inch (15.24 cm) diameter ducting extending to the lower back guard area. The minimum connection at this point is 8-inches (20.32 cm). The upper basket (tumbler) includes no internal ductwork (not provided by ADC, must be purchased elsewhere, must be a minimum of 6-inches [15.24 cm], and only to the top of the dryer). At this point, (where the internal ducting ends at top of the dryer), 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.

NOTE: Common (“Y”) exhaust connections of the top basket (tumbler) and bottom basket (tumbler) should be installed in such a manner that the back guards/panels can be removed easily for servicing.

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) of water column (W.C.) when both baskets (tumblers) are operating.

15

3.Single Dryer Venting

When possible, it is suggested that a separate exhaust duct be provided for each dryer. 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. It is suggested that the use of 90º turns be avoided; use 30º or 45º angles instead. The shape of the exhaust ductwork is not critical so long as the minimum cross-sectional area is provided.

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.).

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

a. Single Dryer Venting - with each basket (tumbler) independently vented ALL the way to the outdoors.

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

IMPORTANT: UNDER NO CIRCUMSTANCES can the dryer be vented to the outdoors using a 6-inch (15.24 cm) diameter exhaust duct!!!

When independent exhaust ducting is used for each basket (tumbler), the connection size at the point where the internal ducting (6-inch [15.24 cm] diameter) leaves the dryer, the minimum size connection is 8-inches (20.32 cm) in diameter (54 square inches [348.4 square centimeters] cross-sectional area) and this is only true providing: (Refer to the illustration on page 17 for details.)

1)The maximum duct run is no more than 15 feet (4.6 meters).

2)The ductwork is on a horizontal run (no riser).

3)There is no more than one (1) elbow, which includes the outside outlet (i.e., elbow used for outside protection).

IMPORTANT: Even though the dryer’s exhaust outlet size is 6-inches (15.24 cm) in diameter (at both the top basket [tumbler] elbow where it leaves the dryer), the minimum connection at this point of exit from the dryer is 8-inches (20.32 cm) in diameter (54 square inches [348.4 square centimeters] cross-sectional area).

16

17

b.Single Dryer Venting - with common (top basket [tumbler] and bottom basket [tumbler] connected together) exhaust connections.

If the top and bottom baskets (tumblers) connect or “Y” together as noted is Section E, the minimum diameter size at the “Y” or point of connections is 10-inches (25.4 cm) in diameter (80 square inches [516.13 square centimeters] cross-sectional area). Additionally, the maximum ductwork travel from the top of the dryer to the outside exhaust outlet must not exceed 15 feet (4.6 meters). Refer to the illustration above for examples.

The vertical ducting need not be a minimum of 10-inches (25.4 cm) in diameter ALL the way into the dryer. Connections inside the dryer can be 6-inches (15.24 cm) in diameter for the top basket (tumbler) and for the bottom basket (tumbler) increased to 8-inches (20.32 cm) up to the top area of the dryer and then at that point must be a minimum of 10-inches (25.4 cm) in diameter (80 square inches [516.13 square centimeters] cross-sectional area). Additionally, the length of the exhaust run cannot exceed 15 feet (4.6 meters) from the top of the dryer to the point where the exhaust ends outside.

4.Multiple Dryer Venting (with Common Main Duct)

If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers or baskets (tumblers) may be channeled into a common main duct. Each dryer/basket (tumbler) is provided with a back draft damper. The individual ducts should enter the bottom or side of the main duct at an angle of not more than 45º in the direction of the airflow.

18

The main common duct may be any shape so long as the minimum cross-sectional area is provided. The main duct should be tapered with the diameter increasing before each individual duct is added as per the illustrations on page 20 and page 21.

The maximum length of venting from the last dryer to where it exhausts is the following:

VERTICAL - venting run must not exceed 8 feet (2.44 meters). This calculation compensates for the maximum use of three (3) elbows including the two (2) elbows creating 180º (turned downward) outside outlet.

HORIZONTAL - venting run must not exceed 15 feet (4.6 meters). This calculation compensates for the maximum use of only one (1) elbow which is the outside outlet protection.

IMPORTANT: No more than four (4) dryers (eight [8] baskets [tumblers]) maximum should be connected to one (1) main common duct. Refer to the applicable section of this manual for specific common venting size.

NOTE: The distance between the dryer single ducts being connected to the main common duct must be a minimum of 31-1/2” (80.01 cm) dryer’s width.

The ductwork should be laid out in such a manner where allowances are made at the rear area of the dryer for removal of rear service panels/guards.

The illustrations on page 20 and page 21 show the minimum cross-sectional area for multiple dryer venting. These figures must be increased in proportion if the main duct run from the last dryer to where it exhausts, has numerous elbows, or is unusually long.

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

NOTE: Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.

a.Multiple Dryer Venting - where each basket (tumbler) is individually vented.

With multiple venting where each basket (tumbler) is vented independently (a separate exhaust is used for each basket [tumbler]) to the common main duct, a minimum of an 8-inch (20.32 cm) diameter duct (50 square inches [322.58 square centimeters] cross-sectional area) connection between the dryer and common main duct is acceptable providing this duct does not exceed 8 feet (2.44 meters) in length.

IMPORTANT: No more than four (4) dryers (eight [8] baskets [tumblers]) can be connected to one

(1) common duct vent.

19

NOTE: The distance between the dryer single ducts being connected to the main common duct must be a minimum of 31-1/2” (80.01 cm) dryer’s width.

NOTE: The ductwork should be laid out in such a manner where allowances are made at the rear area of the dryer for removal of rear service panels/guards.

IMPORTANT: Individual ducts being added to the main common vent must enter the main common vent ductwork at an angle not more than 45º in the direction of the airflow.

The illustration above shows the minimum cross section area for multiple (common) dryer venting. The maximum length of venting from the last dryer to where it exhausts is the following: VERTICAL - venting run must not exceed 8 feet (2.44 meters).

HORIZONTAL - venting run must not exceed 15 feet (4.6 meters).

20

These figures must be increased in proportion if the main duct run from the last dryer has numerous elbows or is unusually long. For extended runs or where more elbows are added, the cross-sectional area of the duct can only be increased to an extent and a professional heating, venting, and air conditioning (HVAC) firm should be consulted for proper venting information.

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

NOTE: Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.

b.Multiple Dryer Venting - where baskets (tumblers) of each dryer “Y” together.

With multiple venting where the top basket (tumbler) and bottom basket (tumbler) are connected or “Y” together as described in Section E (page 12 through page 14), the minimum diameter size at the “Y” (point of connection) and main common duct is 10-inches (25.4 cm) in diameter (80 square inches [516.13 square centimeters] cross-sectional). This duct run cannot exceed 8 feet (2.44 meters) in length.

21

IMPORTANT: No more than four (4) dryers (eight [8] baskets [tumblers]) can be connected to one

(1) common duct vent.

NOTE: The distance between the dryer single ducts being connected to the main common duct must be a minimum of 31-1/2” (80.01 cm) dryer’s width.

The ductwork should be laid out in such a manner where allowances are made at the rear area of the dryer for removal of rear service panels/guards.

IMPORTANT: Individual ducts being added to the main common vent must enter the main common vent ductwork at an angle not more than 45º in the direction of the airflow.

The illustration on the previous page shows the minimum cross-sectional area for multiple dryer venting.

The maximum length of venting from the last dryer to where it exhausts is the following:

VERTICAL - venting run must not exceed 8 feet (2.44 meters).

HORIZONTAL - venting run must not exceed 15 feet (4.6 meters).

These figures must be increased in proportion if the main duct run from the last dryer has numerous elbows or is unusually long. For extended runs or where more elbows are added, the cross-sectional area of the duct can only be increased to an extent and a professional heating, venting, and air conditioning (HVAC) firm should be consulted for proper venting information.

IMPORTANT: Exhaust back pressure must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.) when both baskets (tumblers) are operating.

NOTE: Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.

22

IMPORTANT VENTING REMINDERS

1.Ductwork sizing and installation should be done by a qualified professional.

2.The dryer must be vented to the outdoors.

3.The ductwork should be routed as short as possible to the outdoors with as few turns as possible.

4.Avoid 90º turns, use 30º or 45º turns instead.

5.The size (cross-sectional area) of the ductwork will depend on the application (i.e., single dryer venting, common venting, etc.), as well as the length of the duct and the amount of elbows. DO NOT exceed the specifications noted 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!!!

6.The inside of the ductwork should be as smooth as possible with no projections from the sheet metal screws.

7.ALL ducts should be taped to prevent moisture and lint from escaping into the building.

8.Inspection/clean out doors should be installed throughout strategic points in the ductwork for periodic inspection and cleaning.

9.Whenever the duct passes through 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.

10.The outside of the ductwork must be protected from the weather. A 90º elbow must be used for a horizontal run and when going vertically through the roof by using a 180º turn to point the opening downward. The distance between the exhaust duct and the nearest obstruction (i.e., roof or ground) must be twice the diameter of the duct.

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

12.The ductwork exhaust outlets should not be located near make-up air openings. If make-up air openings are located too close to the exhaust outlet, lint and fumes may be drawn back into the dryer area through these openings.

13.Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust duct must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.) when both baskets (tumblers) are operating.

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

3.Piping Connections

ALL components/materials must conform to National Fuel Gas Code SpecificationsANSI Z223.1-LATEST EDITION, or in Canada, 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), as well as local codes and ordinances and must be done by a qualified professional. It is important that gas pressure regulators meet applicable pressure requirements, and that gas meters be rated for the total amount of ALL the appliance BTUs being supplied.

The dryer is provided with two (2) 3/4” N.P.T. inlet pipe connections (one [1] for each basket [tumbler]) at the rear of the dryer. If a separate feed is provided for each basket (tumbler) from the main supply line (header), then a 3/4” line connection is sufficient. However, if the top basket (tumbler) and the bottom basket (tumbler) are connected together, the supply from this connection to the header must be a minimum of 1-inch (2.54 cm) and must not exceed 50 feet (15.24 meters). For typical gas connections, refer to the illustration on page 29. It is recommended that a gas shutoff valve be provided to the gas supply line of each dryer basket (tumbler) for ease in servicing.

The size of the gas supply line (header) will vary, depending on the distance this supply line travels from the gas meter (or in case of L.P. gas, the supply tank), the number of tees, other gas-operated appliances on the supply line, etc. Specific information regarding supply line size should be determined by the gas supplier.

NOTE: Undersized gas supply piping can create a low or inconsistent gas pressure, which will result in erratic operation of the burner ignition system.

Consistent gas pressure is essential at ALL gas connections. It is recommended that 3/4” (19.05 cm) pipe loop be installed in the supply line servicing the bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if natural gas line pressure exceeds 12.0 inches (29.9 mb) of water column (W.C.) pressure. Refer to the illustration on the following page for details.

IMPORTANT: Water column pressure of 3.5 inches (8.7 mb) for natural gas dryers and 10.5 inches (26.1 mb) for L.P. gas is required at the gas valve pressure tap of each dryer for proper and safe operation.

A 1/8” N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas supply line immediately upstream of each dryer.

IMPORTANT: Pipe joint compounds that resist the action of natural and L.P. gases must be used.

WARNING: Test ALL connections for leaks by brushing on a soapy water solution (liquid detergent works well).

WARNING: NEVER TEST FOR LEAKS WITHAFLAME!!!

ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LATEST EDITION, or in Canada, 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), as well as local codes and ordinances and must be done by a qualified professional. It is important that gas pressure regulators meet applicable pressure requirements, and that gas meters be rated for the total amount of ALL the appliance BTUs being supplied.

H. PREPARATION FOR OPERATION

The following items should be checked before attempting to operate the dryer:

1.Read and follow ALL CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.

2.Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label located behind the left coin control panel on the right wall (refer to Section IX of this manual).

3.Check to assure that the dryer is connected to the type of heat/gas indicated on the dryer data label.

4.The sail switch damper assemblies are installed and preadjusted at the factory prior to shipment. However, each sail switch adjustment should be checked to assure this important safety control is functioning.

5.Check bolts, nuts, screws, terminals, and fittings for security.

6.Be sure ALL gas shutoff valves are in the open position.

7.Be sure ALL back panels (guards) and electric box covers have been replaced.

8.Check ALL service doors to assure that they are closed and secured in place.

9.Rotate the baskets (tumblers) by hand to be sure they move freely.

I. PREOPERATIONAL TESTS

ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit.

1.Turn on electrical power to the dryer.

a.Open ALL gas shutoff valves.

2.Computer System Operational

a.COIN MODELS ONLY

1)The light emitting diode (L.E.D.) display(s) will flash back and forth between “FILL” and the amount needed to start the dryer (i.e., “25”), which means that the dryer is available and 25¢ is required to start it.

2)Insert the proper number of coins into coin acceptor. Once the correct amount needed to start the dryer has been inserted, the L.E.D. display will read “PUSH.”

3)Start the dryer by pressing the desired setting (i.e., LOW TEMP). The L.E.D. display will now read selection (setting) made and the amount of time vended (i.e., “LO 10”).

30

NOTE: The dryer can be stopped at any time by opening the main door. To restart the dryer, shut the main door and press the desired setting.

4)Open main door to stop the dryer, and change selection to “PERM PRESS” (medium) setting. Repeat this procedure, but change the selection (setting) to “HIGH TEMP.” This will confirm that the selection key circuits are functioning properly.

NOTE: Selection (setting) changes can be made at any time during the drying cycle by opening and closing the main door and then making a new selection.

5)Repeat above procedure for other basket (tumbler).

b.OPL (NON-COIN) MODELS ONLY

1)The light emitting diode (L.E.D.) display(s) will read “FILL,” which means that the dryer is available.

2)Start the dryer by pressing the desired setting “LOW TEMP.” The L.E.D. display will now read selection (setting) made and the drying time portion of the L.E.D. display will read “00” and count upwards in time.

NOTE: The dryer can be stopped at any time by opening the main door. To restart the dryer, shut the main door and press the desired setting.

3)Open main door to stop the dryer, and change selection to “PERM PRESS” (medium) setting. Repeat this procedure, but change the selection (setting) to “HIGH TEMP.” This will confirm that the selection key circuits and door switch circuits are functioning properly.

NOTE: Selection (setting) changes can be made at any time during the drying cycle by opening and closing the main door and then making a new selection.

4)Repeat above procedure for the other basket (tumbler).

3.Heat Circuit Operational Test

a.GAS MODELS

When a gas dryer is first started (during the initial start-up), it has a tendency not to ignite on the first attempt. This is because the gas supply piping is filled with air. It may take a few minutes for this air to be purged from the lines.

The dryer is equipped with a Direct Spark Ignition (DSI) system, which has internal diagnostics. If ignition is not established after the first attempt, the heat circuit DSI module will try two (2) additional times and if a flame is not established, the DSI module will lockout until it is manually reset. To reset the DSI system, open and close the main door and restart the dryer (press desired temperature selection).

NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.

Once ignition is established, a gas pressure reading should be taken at the gas valve pressure tap of each dryer to assure that the water column (W.C.) pressure is correct and consistent.

31

NOTE: Water column (W.C.) pressure requirements (measured at the gas valve pressure tap from the manifold side of the gas valve):

Natural Gas .................................

3.5 Inches (8.7 mb) water column.

Liquid Propane (L.P.) Gas ............

10.5 Inches (26.1 mb) water column.

IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank) or an external regulator must be added to each dryer.

4.Make a complete operational check of ALL safety related circuits (i.e., lint basket switches and sail switches).

NOTE: The sail switch can be checked for proper operation by opening the main door, and while holding the main door switch in, start the dryer. The heating units should not come on. If it does, make the necessary adjustments.

5.Each basket (tumbler) should be operated through one (1) complete cycle to assure that no further adjustments are necessary and that ALL components are functioning properly.

BASKET (TUMBLER) COATING

The basket (tumbler) is treated with a protective coating. We suggest dampening old garments or cloth material with a solution of water and nonflammable mild detergent and tumbling them in the basket (tumbler) to remove this coating.

NOTE: Drying and cooling cycles are complete when the light emitting diode (L.E.D.) display reads “donE.”

6.Computer Programs/Selections

Each microprocessor controller (computer) has been preprogrammed by the factory with the most commonly used program (parameter) selections. If microprocessor controller (computer) program changes are required, refer to the Microprocessor Controller (Computer) Programming Manual which was shipped with the dryer.

The dryer is available for use when the light emitting diode (L.E.D.) display reads “FILL” and/or the amount needed to start the dryer (i.e., “25”). Once the load has been put into the dryer and the main door is closed, start the dryer as follows:

a.Insert the proper number of coins into the coin acceptor. Once the correct “Amount To Start” has been inserted, the L.E.D. display will read “PUSH.”

b.Determine fabric setting (selection). Setting “HIGH TEMP” is the high-temperature range, “PERM PRESS” is the medium-temperature range, and “LOW TEMP” is the low-temperature range.

Once the fabric temperature setting (selection) has been determined, you start the dryer by pressing the fabric setting key desired (i.e., “LOW TEMP”).

c.The dryer will now start, and the L.E.D. display for the basket (tumbler) selected will read the setting and the time vended (i.e., “LO 10”).

d.The cycle time will count down until the drying and cooling cycles are completed.

e.Upon completion of the drying cycle and cooling cycle, the dryer will shut off, the tone (buzzer) will sound for 5-seconds, and the L.E.D. display will read “donE.”

NOTE: If theAnti-Wrinkle program is active, the L.E.D. display will remain reading “donE,” and the microprocessor controller (computer) will proceed through theAnti-Wrinkle program until the maximum “Active Guard Time” has expired or until the main door is opened, whichever comes first.

NOTE: If theAnti-Wrinkle program is not active or in use, the L.E.D. display will read “donE” until the main door is opened, at which time, the L.E.D. display will read “FILL” and the “Amount To Start.”

f.Notes

1)The dryer basket (tumbler) can be stopped at any time by opening the main door. To restart dryer, shut the main door and press desired setting.

NOTE: When a cycle is interrupted by opening the main door, the cycle time will continue to count downward, regardless if the door is open or closed, until a keyboard (touch pad) selection is made.

33

2)Selection (setting) changes can be made at any time during the drying cycle by opening and closing the main door and then making a new selection.

3)Additional time can be purchased at any time. If the dryer is in operation (drying mode) and additional coins are inserted, the light emitting diode (L.E.D.) display will read the additional time for amount inserted.

2.Non-Coin (OPL) Dryers

The dryer is available for use when the L.E.D. display reads “FILL.” Once the load has been put into the dryer and the main door is closed, start the dryer as follows:

a.Determine fabric setting (selection). Setting “HIGH TEMP” is the high-temperature range, the “PERM PRESS” is the medium-temperature range, and the “LOW TEMP” setting is the low-temperature range.

b.Once the fabric temperature setting (selection) has been determined, you start the dryer by pressing the fabric setting key desired.

c.The dryer will now start, and the L.E.D. display for the basket (tumbler) selected will read the setting (selection) and the drying portion of the L.E.D. display will read “00” and count upwards in time.

d.Upon completion of the drying cycle and cooling cycle, the dryer will shut off, the tone (buzzer) will sound for 5-seconds, and the L.E.D. display will read “donE.”

NOTE: If theAnti-Wrinkle program is active, the L.E.D. display will remain reading “donE,” and the microprocessor controller (computer) will proceed through theAnti-Wrinkle program until the maximum “Active Guard Time” has expired or until the main door is opened, whichever comes first.

NOTE: If theAnti-Wrinkle program is not active or in use, the L.E.D. display will read “donE” until the main door is opened, at which time, the L.E.D. display will read “FILL.”

e.Notes

1)The dryer basket (tumbler) can be stopped at any time by opening the main door. To restart dryer, shut the main door and press desired setting.

NOTE: When a cycle is interrupted by opening the main door, the cycle time will continue to count upward, regardless if the door is open or closed until a keyboard (touch pad) selection is made.

2)Selection (setting) changes can be made at any time during the drying cycle by opening and closing the main door and then making a new selection.

34

SECTIONVII

ROUTINE MAINTENANCE

A. CLEANING

A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer, as well as throughout the ductwork system. The frequency of cleaning can best be determined from experience at each location. Maximum operating efficiency is dependent upon proper air circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, an ADC dryer will provide many years of efficient, trouble free, and most importantly safe operation.

WARNING: LINT FROM MOST FABRICS IS HIGHLY COMBUSTIBLE. THE ACCUMULATION OF LINT CAN CREATEAPOTENTIALFIRE HAZARD.

WARNING: KEEP DRYER AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND LIQUIDS.

NOTE: Suggested time intervals shown are for average usage, which is considered six (6) to eight (8) operational (running) hours per day.

IMPORTANT: Dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months, inspect the exhaust ducting and remove any lint build up.

SUGGESTED CLEANING SCHEDULE

DAILY (beginning of each work shift)

Clean lint from lint drawer and screen assembly.

Inspect lint screens or drawers for damage and replace if torn.

WEEKLY

Clean lint accumulation from around microprocessor temperature sensor probes and sensor bracket assemblies.

90 DAYS

Remove lint from the motor air vents and surrounding area.

IMPORTANT: Lint accumulation will restrict the airflow over the motors, causing overheating and irreparable motor damage. Motor failure due to lint accumulation will VOID THE WARRANTY.

WARNING: TOAVOID THE HAZARD OF ELECTRICALSHOCK, DISCONTINUE ELECTRICALSUPPLYTO THE DRYER.

39

Remove lint accumulation from around the openings in the dryer’s back panels.

Remove lint from gas valve burner train area with a vacuum cleaner with brush attachment. Remove any lint accumulation from the coin acceptor area, including the optical switch.

Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from the dryer’s internal exhaust ducting.

WARNING: THEACCUMULATION OF LINT IN THE EXHAUST DUCTWORK CAN CREATEAPOTENTIALFIRE HAZARD.

WARNING: DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR.

Inspect and remove lint accumulation from the dryer’s exhaust ductwork back draft dampers.

NOTE: A back draft damper that is sticking partially closed can result in slow drying and shutdown of the heat circuit safety switches and/or thermostats.

6 MONTHS

In the cleaning of the dryer cabinet, avoid using harsh abrasives. A product for the cleaning of appliances is recommended.

ALL bearings and setscrews should be checked to insure they are tight.

B. ADJUSTMENTS

7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER

Inspect bolts, nuts, screws (bearing setscrews), grounding connections, nonpermanent gas connections (unions, shutoff valves, and orifices), and electrical terminals. Tighten loose V-belts when necessary and check the alignment. Inspect drive motor (impellor/fan) shaft belt. A cracked or seriously frayed belt should be replaced. Complete operational check of controls and valves. Complete operational check of ALL safety devices (door switches, lint compartment switches, sail switches, burner and hi-limit thermostats).

40

C. LUBRICATION

The motor bearings, idler bearings, and under normal/most conditions the basket (tumbler) bearings are permanently lubricated. It is physically possible to relubricate the basket (tumbler) bearings if you choose to do so, even though this practice is not necessary. Use Shell Alvania #2 grease or its equivalent. The basket (tumbler) bearings used in the dryer DO NOT have a grease fitting. Provisions are made in the bearing housing for the addition of a grease fitting which can be obtained elsewhere, or from ADC by ordering kit Part No. 882159 which includes two (2) grease fittings.
