SECTION I  
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 theADC Traffic Manager at (508) 678-9000.  
IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.

C. DRYER ENCLOSURE REQUIREMENTS  
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 (0.60 meters) from the nearest obstruction (i.e., wall) for ease of installation,  
maintenance, and service. Bulkheads and partitions should be made from noncombustible materials. The  
clearance between the bulkhead header and the dryer must be a minimum of 4-inches  
(10.16 cm) and must not extend more than 4-inches (10.16 cm) to the rear of the dryer front. The bulkhead  
facing must not be closed in ALL the way to the top of the dryer. A 2-inch (5.08 cm) clearance is required.  
NOTE: Bulkhead facing should not be installed until after dryer is in place. Ceiling area must be  
located a minimum of 12-inches (30.48 cm) above the top of the dryer.  
IMPORTANT: Even though a minimum of only 12-inches (30.48 cm) is required, 18-inches  
(45.72 cm) or more is suggested, for steam dryers and especially in cases where  
sprinkler heads are over the dryers.  
NOTE: When fire sprinkler systems are located above the dryers, a minimum of 18-inches (45.72 cm)  
above the dryer console (module) is suggested. Dryers may be positioned sidewall to sidewall  
however, 1 or 2-inches (2.54 cm or 5.08 cm) is suggested between dryers (or wall) for ease  
of installation and maintenance. Allowances must be made for the opening and closing of the  
control and lint doors.

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 performance of each dryer. An  
unrestricted source of air is necessary for each dryer. An airflow of 2,150 cfm (cubic feet per minute) - 60.88  
cmm (cubic meters per minutes) - must be supplied to each gas, electric, and steam dryer. As a general rule, an  
unrestricted air entrance from the outdoors (atmosphere) of a minimum of 3 square feet (0.28 square meters) is  
required for each gas, electric, and steam dryer.  
To compensate for the use of registers or louvers used over the openings, this make-up air area 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.  
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 six (6) gas dryers, two (2) openings measuring 3 feet by 3 feet (0.91  
meters by 0.91 meters) 9 square feet (0.84 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.  
15  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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.  
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: This dryer produces combustible lint and must be exhausted to the outdoors.  
CAUTION: DRYER MUST BE EXHAUSTED TO THE OUTDOORS.  
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORKCAN  
CREATE A POTENTIAL FIREHAZARD.  
NOTE: When a dryer is exhausted separately, it is recommendedthat a back draft damper be  
installed.  
NOTE: When dryers are exhausted into a multiple (common) exhaust line, each dryer must be  
supplied with a back draft damper.  
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. Single or independent dryer venting is recommended. When  
single dryer venting is used, the ductwork from the dryer to the outside exhaust outlet must not exceed20  
feet (6.09 meters). In the case of multiple (common) dryer venting, the distance from the last dryer to the  
outside exhaust outlet must not exceed20 feet (6.09 meters). The shape of the ductwork is not critical so  
long as the minimum cross section area is provided. It is suggested that the use of 90º turns in ducting be  
avoided; use 30º and/or 45º angles instead. The radius of the elbows should preferably be 1-1/2 times the  
diameter of the duct. 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  
number of elbows added.

ALL 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 of lint from the ductwork.  
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: 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: 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.  
a. Outside Ductwork Protection  
1) 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 exhaust 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.  
IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust  
ductwork.

2. Single Dryer Venting  
Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct 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 90° turns in ducting be avoided; use 30° and/or 45° angles instead.  
The shape of the exhaust ductwork is not critical so long as the minimum cross section area is provided.  
IMPORTANT: Minimum duct size for a gas, electric, or steam dryer with a vertical run and not more  
than three (3) elbows (including dryer connection and outside outlets) is 16-inches  
(40.64 cm) for a round duct or 14-1/2” by 14-1/2” (36.83 cm by 36.83 cm) for a  
square duct. DUCT SIZE MUST NOT BE REDUCED ANYWHERE  
DOWNSTREAM OF DRYER.  
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.).  
It is suggested that the ductwork from each dryer (minimum 14-inches [35.56 cm] for a gas dryer or electric  
dryer and 16-inches [40.64 cm] for a steam dryer) not exceed 20 feet (6.09 meters) with no more than three  
(3) elbows (including dryer connections and outside exhaust outlets). If the ductwork exceeds 20 feet (6.09  
meters) or has numerous elbows, the cross section area of the ductwork must be increased in proportion to  
the length and number of elbows in it. In calculating duct size, the cross section area of a square or  
rectangular duct must be increased by twenty percent (20%) for each additional 20 feet (6.09 meters).  
The diameter of a round exhaust duct should be increased ten percent (10%) for each additional 15 feet  
(4.57 meters). Each 14-inch (35.56 cm) 90° elbow is equivalent to 30 feet (9.14 meters) and each 16-inch  
(40.64 cm) 90° elbow is equivalent to 36 feet (10.97 meters).  
18  
Download from Www.Somanuals.com. All Manuals Search And Download.  
IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased  
to an extent. Maximum proportional ductwork runs cannot exceed 20 feet (6.09  
meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows.  
When the ductwork approaches the maximum limits as noted in this manual, a  
professional heating, venting, and air conditioning (HVAC) firm should be consulted  
for proper venting information.  
ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,  
which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be  
connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.  
Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and  
cleaning of lint from the ductwork.  
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.  
a. Outside Ductwork Protection  
1) 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 exhaust 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 nearest obstruction.  
IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust  
ductwork.  
3. Multiple Dryer (Common) Venting  
If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be  
channeled into a “common main duct.” The individual ducts should enter the bottom or side of the main  
duct at an angle not more than 45° in the direction of airflow and should be spaced at least 48-3/8” (122.87  
cm) apart. The main duct should be tapered, with the diameter increasing before each individual 14-inch  
(35.56 cm) minimum for gas dryers or electric dryers, or 16-inch (40.64 cm) minimum for steam dryers  
(duct is added).  
IMPORTANT: The dryer is not provided with a back draft damper. When exhausted into a multiple  
(common) exhaust line, a back draft damper must be installed at each dryer duct.  
IMPORTANT: No more than four (4) dryers should be connected to one (1) main common duct.  
19  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The main duct may be any shape or cross-sectional area, so long as the minimum cross section area is  
provided. The illustrations on page 21 show the minimum cross section area for multiple dryer round or  
square venting. These figures must be increased 10 square inches (64.51 square centimeters) when  
rectangular main ducting is used, and the ratio of duct width to depth should not be greater than 3-1/2 to 1.  
These figures must be increased in proportion if the main duct run to the last dryer to where it exhausts to  
the outdoors is unusually long (over 20 feet [6.09 meters]) or has numerous elbows (more than two [2]) in  
it. In calculating ductwork size, the cross section area of a square or rectangular duct must be increased  
twenty percent (20%) for each additional 20 feet (6.09 meters). The diameter of a round exhaust must be  
increased ten percent (10%) for each additional 20 feet (6.09 meters). Each 90° elbow is equivalent to an  
additional 15 feet (4.57 meters).  
IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be  
increased to an extent. Maximum proportional ductwork runs cannot exceed  
20 feet (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with  
two (2) elbows. When the ductwork approaches the maximum limits as noted in this  
manual, 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 each 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.).  
The duct should besmooth inside with no projections from sheet metal screws or other obstructions, which  
will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be  
connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.  
Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and  
cleaning of lint from the ductwork.  
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.

3. Electrical Connections  
NOTE: A wiring diagram is included with each dryer and is affixed to the rear upper right guard/panel  
of the dryer.  
The only electrical input connections to the dryer are the 3-phase (3Ø) power leads (L1, L2, and L3),  
GROUND, and in the case of 4 wire service, the neutral. Providing local codes permit, power connections  
to the dryer can be made by the use of a flexible underwriters laboratory listed cord/pigtail (wire size must  
conform to rating of the dryer), or the dryer can be hard wired directly to the service breaker. In ALL  
cases, a strain relief must be used where the wire(s) enter the dryer electrical service (relay) box.  
a. Gas Model and Steam Model Dryers  
These electrical connections are made at the terminal block located in the electric service/relay box at  
the rear, upper left hand corner of the dryer. To gain access into this service box, the service cover  
(upper back guard) must be removed.  
b. Electric Model Dryers  
For electric model dryers made to operate at 208 VAC or 240 VAC, the electrical input connection is  
made into the terminal block located at the upper rear of the dryer (refer to the illustration on page  
27). For electric model dryers made to operate at 380 VAC, 416 VAC, 440 VAC, or 480 VAC, the  
electrical input connection is made to the oven relay located at the upper rear of the dryer (refer to the  
illustration on page 27). Input connection wiring must be sized properly to handle the dryer's current  
draw. This information is printed on the dryer's data label, which is affixed to the left side panel/wall  
area behind the control door.  
NOTE: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED.

4. Grounding  
A ground (earth) connection must be provided and installed in accordance with state and local codes. In  
the absence of these codes, grounding must conform to applicable requirements of the National Electrical  
Code ANSI/NFPA NO. 70-LATEST EDITION, or in Canada, the installation must conform to applicable  
Canada Standards: Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION. The  
ground connection may be to a proven earth ground at the location service panel.  
NOTE: A grounding connection (terminal lug) is provided in the dryer's electrical service/relay box at  
the rear.  
For added personal safety, when possible, it is suggested that a separate ground wire (sized per local codes)  
be connected from the ground connection of the dryer to a grounded cold water pipe. DO NOT ground to  
a gas or hot water pipe. The grounded cold water pipe must have metal to metal connections ALL the  
way to electrical ground. If there are any nonmetallic interruptions, such as a meter, pump, plastic, rubber,  
or other insulating connectors, they must be jumped out with no. 4 copper wire and securely clamped to  
bare metal at both ends.  
IMPORTANT: For personal safety and proper operation, the dryer must be grounded. For proper  
operation of the microprocessor controller (computer), an earth (zero) ground is  
required.  
NOTE: Grounding via metallic electrical conduit (pipe) is not recommended.

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 a 1-inch N.P.T. inlet pipe connection extending out the back area of the burner  
box. The minimum pipe size connection (supply line) to the dryer is 1-inch N.P.T. For ease of servicing, the  
gas supply line of each dryer must have its own shutoff valve.  
The size of the main gas supply line (header) will vary depending on the distance this line travels from the  
gas meter or, in the case of L.P. gas, the supply tank, other gas-operated appliances on the same 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 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 a 1-inch (2.54 cm)  
pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure regulatormust be  
installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches (29.9 mb) of water  
column pressure (W.C.).  
IMPORTANT: A water column pressure of 3.5 inches (8.7 mb) for natural gas and 10.5 inches  
(26.1 mb) for L.P. dryers is required at the gas valve pressure tap of each dryer for  
proper and safe operation.  
A 1/8-inch 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.  
IMPORTANT: Test ALL connections for leaks by brushing on a soapy water solution (liquid  
detergent works well).  
WARNING: NEVER TEST FOR GAS LEAKS WITH A FLAME!!!  
ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LATEST  
EDITION, or in Canada, the Canadian Installation Codes CAN/CGA-B149.1-M91 (Natural Gas) or CAN/  
CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION.  
It is important that gas pressure regulators meet applicable pressure requirements, and that gas meters be  
rated for the total amount of appliance BTUs being supplied.

IMPORTANT: The dryer and its individual shutoff valve must be disconnected from the gas  
supply piping system during any pressure testing of that system at test pressures  
in excess of 1/2 psig (3.5 kPa).  
NOTE: The dryer must be isolated from the gas supply piping system by closing its individual  
manual shutoff valve during any pressure testing of the gas supply piping system at test  
pressures equal to or less than 1/2 psig (3.5 kPa).

H. STEAM INFORMATION  
It is your responsibility to have ALL steam plumbing connections made by a qualified professional to assure that  
the installation is adequate and conforms to local and state regulations or codes.  
IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in  
component failure, which will VOID THE WARRANTY.  
NOTE: The dryer is manufactured with a pneumatic (piston) damper system, which requires an  
external supply of clean, dry, and regulated air (80 PSI +/- 10 PSI [5.51 bars +/- 0.69 bars]).  
Refer to Steam Damper Air System Connections, Section H, item 4.  
1. Steam Coil PH Level  
The normal PH level for copper type steam coils must be maintained between a value of 8.5 to 9.5. For  
steel type steam coils the PH level must be maintained between a value of 9.5 to 10.5. These limits are  
set to limit the acid attack of the steam coils.  
IMPORTANT: Coil failure due to improper PH level will VOID THE WARRANTY.  
2. Steam Requirements, High Pressure

3. Installation Instructions  
To insure that an adequate supply of steam is provided, be sure that the steam supply and steam return lines  
are sized and laid out as stipulated in this manual. Inadequate steam supply and steam return lines are sized  
and laid out as stipulated in this manual. Inadequate steam supply and steam return lines or improper steam  
plumbing will result in poor performance and can cause component failure. Clean, dry, and regulated steam  
must be provided to the dryer.  
IMPORTANT: Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY.  
32  
Download from Www.Somanuals.com. All Manuals Search And Download.  
a. The pressure of the condensate in the steam supply will cause water hammer and subsequent heat  
exchanger (steam coil) failure. The steam supply connection into the main supply line must be made  
within a minimum 12-inch (30.48 cm) riser. This will prevent any condensate from draining towards the  
dryer.  
b. The steam supply piping to the dryer must include a 12-inch (30.48 cm) rise along with a drip trap and  
check valve. This will prevent any condensate from entering the steam coil.  
c. Flexible hoses or couplings must be used. The dryer vibrates slightly when it runs and this will cause the  
steam coil connections to crack if they are hard piped to the supply and return mains.  
d. Shutoff valves for each dryer should be installed in the supply, return, and drip trap return lines. This  
will allow the dryer to be isolated from the supply and return mains if the dryer needs maintenance work.  
e. Install an inverted bucket steam trap and check valve for each unit at least 12-inches (30.48 cm) below  
steam coil as close to the coil as possible.  
1) A trap with a capacity of 1,200 lbs (544 kg) of condensate per hour at 125 PSI (8.61 bars) is needed  
for each unit.  
f. A 3/4-inch (19.05 mm) vacuum breaker should be installed for each unit in the piping. This will prevent  
the condensing steam from causing a vacuum inside the coil and possibly damaging the coil.  
g. The supply and return lines should be insulated. This will save energy and provide safety for the  
operator and maintenance personnel.  
h. Water pockets in the supply line, caused by low points, will provide wet steam to the coil possibly  
causing coil damage. ALL horizontal runs of steam supply piping should be pitched 1/4-inch (6.35 mm)  
for every 1 foot (0.31 meters) back towards the steam supply header causing any condensate in the line  
to drain to the header. Install a bypass trap in any low point to eliminate wet steam.

4. Steam Damper Air System Connections  
The dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of  
compressed air. The air connection is made to the steam damper solenoid valve which is located at the rear  
inner top area of the dryer just above the electric service relay box (refer to the bottom illustration on  
page 35).

Shaded areas are stated in metric equivalents  
b. Air Connection  
Air connection to system --- 1/8-inch N.P.T.  
c. No air regulation or filtration is provided with the dryer. External regulation/filtration of 80 PSI (5.51  
bars) must be provided. It is suggested that a regulator/filter gauge arrangement be added to the  
compressed air line just before the dryer connection. This is necessary to insure that correct and clean  
air pressure is achieved.  
5. Steam Damper System Operation  
The steam damper, as shown in the top illustrationon page 35, allows the coil to stay constantly charged  
eliminating repeated expansion and contraction. When the damper is opened, the air immediately passes  
through the already hot coil, providing instant heat to start the drying process. When the damper is closed,  
ambient air is drawn directly into the basket (tumbler), allowing a rapid cool down.  
Diagram 1 -- shows the damper in the heating (open) mode, allowing heat into the basket (tumbler).  
Diagram 2 -- shows the damper in the cool down (closed) mode, pulling ambient air directly into the basket  
(tumbler) without passing through the coils.  
NOTE: With the dryer off or with no air supply, the damper is in the cool down mode as shown  
in Diagram 2.

6. Steam Damper Air Piston (Flow Control) Operation Adjustment System  
Although the damper operation was tested and adjusted prior to shipping at 80 PSI (5.51 bars), steam damper  
operation must be checked before the dryer is put into operation. Refer to page 34 for instructions to check  
steam damper system operation. If damper air adjustment is necessary, locate flow control valve and make  
necessary adjustments as noted below.

I. PREPARATION FOR OPERATION  
The following items should be checked before attempting to operate the dryer:  
1. Read 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 on  
the left side panel/wall area behind the control door as shown on page 9. In case of 208 VAC or 240 VAC,  
the supply voltage must match the electric service exactly.  
3. GAS MODELS - check to assure that the dryer is connected to the type of heat/gas indicated on the dryer  
data label.  
4. GAS MODELS - the sail switch damper assembly was installed and adjusted at the factory prior to  
shipping. However, each sail switch adjustment must be checked to assure that this important safety  
control is functioning.  
5. GAS MODELS - be sure that ALL gas shutoff valves are in the open position.  
6. Be sure ALL back panels (guards) and electric box covers have been replaced.  
7. Check ALL service doors to assure that they are closed and secured in place.  
8. Be sure lint drawer is securely in place.  
NOTE: LINT DRAWER MUST BE ALL THE WAY IN PLACE TO ACTIVATE SAFETY  
SWITCH OTHERWISE THE DRYER WILL NOT START.  
9. Rotate the basket (tumbler) by hand to be sure it moves freely.  
10. Check bolts, nuts, screws, terminals, and fittings for security.  
11. STEAM MODELS - check to insure air supply (80 PSI [5.51 bars]) is on the dryer.

J. 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 or  
due to marginal location (installation) conditions.  
1. Turn on electric power to the dryer.  
2. Make sure the main door is closed and the lint drawer is securely in place.  
3. Microprocessor controller (computer) system operational test to start dryer...  
a. Light emitting diode (L.E.D.) display will read “FILL.”  
b. Press the “E” (preprogrammed) cycle key on the keyboard (touch pad).  
c. L.E.D. display will quickly read: “Ld30,” “Lc04,” and “F180” (unless special programs requested).  
These codes mean that the dryer is in the timed mode and will operate with heat of 180º F (82º C) for 30  
minutes drying time and have a 4 minute cool down period.  
d. Dryer will now start and the L.E.D. display will read “Dr30” (dry mode for 30 minutes) and count down  
in minutes.  
NOTE: The dryer can be stopped at any time by opening main door or by pressing the “CLEAR/  
STOP” key. To restart the dryer, press the “ENTER/START” key or preprogrammed cycle  
key (i.e., “E”).  
NOTE: Pressing keyboard (touch pad) key “A,” “B,” “C,” “D,” and “F,” will also start the dryer. The  
six (6) preprogrammed drying cycles (“A” through “F”) have been stored in the  
microprocessor controller’s (computer’s) memory. Refer to the computer programming  
manual supplied with this dryer for these preprogrammed cycles.  
4. Check to insure that the basket (tumbler) starts in the clockwise (CW) direction. Additionally, check the  
direction of the blower motor impellor (fan) to insure that impellor (blower/fan) rotates in the clockwise  
(CW) direction as viewed from the front. If it is, the phasing is correct. If the phasing is incorrect, reverse  
two (2) of the leads at L1, L2, or L3 of the power supply connections made to the dryer.  
IMPORTANT: Dryer blower motor (impellor/fan) as viewed from the front must turn in the clockwise  
(CW) direction, otherwise dryer efficiency will be drastically reduced and premature  
component failure can result.  
5. Heat Circuit Operational Test  
a. Gas Models  
1) When the dryer is first started (during initial start-up), the burner has a tendency not to ignite on the  
first attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for  
this air to be purged.  
37  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2) 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 “LOCKOUT” until  
it is manually reset. To reset the DSI system, open and close main door and restart dryer (press the  
“ENTER/START” key).  
NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.  
3) Once ignition is established, a gas pressure test 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.  
NOTE: Water column pressure requirements (measured at the gas valve pressure tap)...  
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.  
b. Electric Models  
1) Check the oven contactors to insure that the electric oven is cycling properly.  
c. Steam Models  
1) Check to insure that steam damper is functioning properly.  
a) The steam damper should not “slam” (open/closed) when it reaches the end of (piston) travel.  
Additionally, the steam damper should not bind or stop during travel. If either of these conditions  
occur, the flow control must be adjusted. (Refer to the Cool Down Mode in top illustrationon  
page 35 for air adjustment instructions.)  
6. Make a complete operational check of ALL safety-related circuits (i.e., lint drawer switch and sail switch  
on gas models).  
NOTE: To check for proper sail switch operation, open the main door and while holding main door  
switch plunger in, start dryer. Dryer should start but heat circuit should not be activated (on).  
If heat (burner) does activate, shut the dryer off and make necessary adjustments.  
7. A reversing basket (tumbler) dryer should never be operated with less than a 60 lb (27 kg) load (dry  
weight). The size of the load will affect the coast-down and dwell (stop) times. The basket (tumbler) must  
come to a complete stop before starting in the opposite direction.  
a. Microprocessor Controller (Computer) Dryer Models  
1) Spin and stop times are not adjustable in the Automatic Mode and have been preprogrammed into  
the microprocessor controller (computer) for a 120-second spin time and a 5-second dwell (stop)  
time.  
2) Spin and stop times are adjustable in the Manual (Timed) Mode.  
38  
Download from Www.Somanuals.com. All Manuals Search And Download.  
b. Dual Timer Dryer Models  
1) Spin and stop times are adjustable at the reversing timer.  
BASKET 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.  
8. Each dryer should be operated through one (1) complete cycle to assure that no further adjustments are  
necessary and that ALL components are functioning properly.  
9. Make a complete operational check of ALL operating controls.  
a. Microprocessor Controller (Computer) Programs and Selections...  
1) Each microprocessor controller (computer) has been preprogrammed by the factory with the most  
commonly used parameter (program) selections. If computer program changes are required, refer  
to the computer programming manual, which was shipped with the dryer.  
b. Dual Timer Dryers Check...  
1) Heating Timer  
2) Cool Down Timer  
3) Temperature Selection Switch  
K. SHUT DOWN INSTRUCTIONS  
If the dryer is to be shut down (taken out of service) for a period of time, the following must be performed:  
1. Discontinue power to the dryer either at the external disconnect switch or the circuit breaker.  
2. Discontinue the gas or steam supply:  
a. GAS MODELS...discontinue the gas supply.  
1) SHUT OFF external gas supply shutoff valve.  
2) SHUT OFF internal gas supply shutoff valve located in the gas valve burner area.  
b. STEAM MODELS...discontinue the steam supply.

SECTION VI  
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 CREATE A POTENTIAL FIRE 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, inspecty the exhaust ducting and remove any lint build up.  
CLEAN THE LINT DRAWER/SCREEN EVERY THIRD OR FOURTH LOAD.  
NOTE: Frequency can best be determined at each location.  
SUGGESTED CLEANING SCHEDULE  
DAILY (beginning of each work shift)  
1. Clean lint from screen.  
2. Inspect lint screen and replace if torn.  
WEEKLY  
Clean lint accumulation from lint chamber, thermostat, and microprocessor temperature sensor (sensor bracket)

B. ADJUSTMENTS  
7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER  
Inspect bolts, nuts, screws (bearing setscrews), and nonpermanent gas connections (unions, shutoff valves,  
orifices, and grounding connections). Motor and drive belts should be examined. Cracked or seriously frayed  
belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of controls and  
valves. Complete operational check of ALL safety devices (door switch, lint drawer switch, sail switch, burner,  
and hi-limit thermostats).  
C. LUBRICATION  
The motor bearings and under normal/most conditions the basket (tumbler) and idler bearings are permanently  
lubricated. It is physically possible to relubricate the basket (tumbler) and idler bearings if you choose to do so  
even though this practice is not necessary. Use Shell Alvania #2or its equivalent. The basket (tumbler) and idler  
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  
(basket [tumbler] ONLY), which includes two (2) fittings.

TROUBLESHOOTING  
IMPORTANT: YOU MUST DISCONNECT AND LOCKOUT THE ELECTRIC SUPPLY  
AND THE GAS SUPPLY OR THE STEAM SUPPLY BEFORE ANY  
COVERS OR GUARDS ARE REMOVED FROM THE MACHINE TO  
ALLOW ACCESS FOR CLEANING, ADJUSTING, INSTALLATION, OR  
TESTING OF ANY EQUIPMENT PER OSHA (Occupational Safety and Health  
Administration) STANDARDS.  
The information provided will help isolate the most probable component(s) associated with the difficulty described.  
The experienced technician realizes, however, that a loose connection or broken/shorted wire may be at fault  
where electrical components are concerned...and not necessarily the suspected component itself.  
Electrical parts should always be checked for failure before being returned to the factory.  
The information provided should not be misconstrued as a handbook for use by an untrained person making  
repairs.

PROCEDURE FOR FUNCTIONAL CHECK  
OF REPLACEMENT COMPONENTS  
1. Microprocessor Controller (Computer) Board  
a. Upon completing installation of the replacement microprocessor controller (computer) board, reestablish  
power to the dryer.  
b. Start the drying cycle.  
c. Verify that the motor(s) and the heat indicator dots, in the microprocessor controller (computer) light  
emitting diode (L.E.D.) display are on. (Refer to the illustration below.)  
d. Verify that motor(s), heat, and door indicator lights on the back side of the microprocessor controller  
(computer) board are lit. (Refer to the illustration below.)  
61  
Download from Www.Somanuals.com. All Manuals Search And Download.  
e. Open main door. The dryer must stop and ALL indicator lights on the back side of the microprocessor  
controller (computer) board must go out. (Refer to the illustration on the previous page.)  
f. Try to restart the dryer with the main door open.  
g. The microprocessor controller (computer) board’s light emitting diode (L.E.D.) display must read “DOOR.”  
h. Close the main door and restart the dryer.  
i. Functional check of microprocessor controller (computer) board is complete.  
2. For Models With Johnson Controls Direct Spark Ignition (DSI) Module (G760)  
Theory Of Operation:  
Start the drying cycle. When the gas burner ignites  
within the chosen trial for ignition time (6-seconds),  
the flame sensor detects gas burner flame and signals  
the DSI module to keep the gas valve open...as long  
as there is a call for heat. The DSI module will  
“LOCKOUT” if the gas burner flame is not sensed  
at the end of the trial for ignition period. The trial for  
ignition period will be repeated for a total of three (3)  
retries/trials (the initial try and two [2] more retries/  
trials). If the flame is not sensed at the end of the  
third retry/trial (inter-purge period of 30-seconds) the  
DSI module will “LOCKOUT” L.E.D. flashes).  
A steady L.E.D. indicator indicates normal  
operation.  
No L.E.D. indicator indicates a power or an internal  
failure has occurred.

3. For Direct Spark Ignition (DSI) System Models Manufactured With ADC Module Part No. 880815  
a. Upon completing installation of the  
replacement DSI module, reestablish power  
to the dryer.  
b. Starting the drying cycle.  
c. The ignition DSI module’s light emitting diode  
(L.E.D.) indicator will light “red” for up to  
approximately 1.5-seconds (prepurge time).  
d. The module’s indicator light will then turn  
“green.” The gas valve will be energized and  
the ignitor probe will spark for approximately  
8-seconds. The burner flame should now  
be established.  
e. With the burner flame on, remove the flame  
sensor wire from the FS terminal of the DSI  
module.  
f. The burner flame must shut off and the ignition  
module must lockout with the DSI module’s  
indicator light “red.”  
g. Stop the drying cycle, with the flame sensor wire still removed, restart the drying cycle.  
h. The ignition module must proceed through the prepurge, with the indicator light “red,” the ignition trial  
time of approximately 8-seconds, with the indicator light “green,” and then proceed to lockout with the  
indicator light “red.”  
i. Functional check of the DSI module is complete.  
1) Replace the flame sensor wire from the FS terminal to the DSI module.

MANUAL RESET HI-LIMIT INSTRUCTIONS  
FOR TIMER OR PHASE 5 WITHOUT HEAT FAULT  
(GAS MODELS ONLY)  
This dryer was manufactured with a burner and basket (tumbler)/lint chamber burner manual reset hi-limit  
thermostat. If either burner manual reset hi-limit thermostat is open prior to the start of the drying cycle, or during  
the cycle, the dryer will not recognize the open state of the burner hi-limit thermostat and will start or continue  
through the drying cycle with no heat. The applicable manual reset hi-limit thermostat must be reset manually.  
This hi-temperature condition may be caused due to a restricted exhaust, poor airflow, or improper burner  
oven operation.  
The location of the burner manual reset hi-limit switch is on the right side of the burner box.  
IMPORTANT  
This dryer is equippedwith a burnerhi-  
limit and tumbler/lint chamber hi-limit  
thermostat which must be reset manually.
