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 +1 (508)
678-9000.
IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.

manual (refer to Exhaust Requirements in Section E).
IMPORTANT: The dryer should be located where a minimum amount of exhaust duct will be
necessary.
9. The dryer must be installed with adequate clearance for air openings into the combustion chamber.
10
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: The dryer must be installed in a location/environment, which the ambient
temperature remains between 40° F (4.44° C) and 130° F (54.44° C).
B. UNPACKING/SETTING UP
Remove protective shipping material (i.e., plastic wrap and/or optional shipping box) from dryer.
IMPORTANT: Dryer must be transported and handled in an upright position at ALL times.
The dryer can be moved to its final location while still attached to the skid or with the skid removed. To remove
skid from the dryer, locate and remove the four (4) lag bolts securing the base of the dryer to the wooden skid.
Two (2) are at the rear base, and two (2) are located in the bottom of the lint chamber. To remove the two (2)
lag bolts located in the lint chamber area, remove the lint drawer and the three (3) Phillips head screws securing
the lint door in place.
1. Leveling Dryer
a. To level the dryer, place 4-inch (10.16 cm) square metal shims or other suitable material under the base
pads. It is suggested that the dryer be tilted slightly to the rear (refer to the illustration above).
b. The V-belts are disconnected from the basket (tumbler) drive motor for shipping. Reconnect V-belts
before starting the dryer.
11

IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.
12
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 24-inches (60.96 cm) 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 front. A 2-inch (5.08 cm) clearance is required between
the bulkhead facing and the top of the dryer.
NOTE: Bulkhead facing should not be installed until after the dryer is in place. Ceiling area must be
located a minimum of 12-inches (30.48 cm) above the dryer top console (module) and
18-inches (45.72 cm) for steam models.
NOTE: When fire sprinkler systems are located above the dryers, a minimum of 18-inches (45.72 cm)
above the dryer console (module) is required. Dryers may be positioned sidewall to sidewall,
however, 1 or 2-inches (2.54 or 5.08 cm) is suggested for ease of installation and
maintenance. Allowances must be made for the opening and closing of the control door and
the lint door.
13
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. The dryer
must be installed with provisions for adequate combustion and make-up air supply.
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 3,700 cfm (cubic feet per minute [104.77
cmm] [cubic meters per minute]) must be supplied to each gas dryer and 4,400 cfm (124.59 cmm) must be
supplied to each steam dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of
a minimum of 4 square feet (0.37 square meters) is required for each gas dryer and a minimum of 4.75 square
feet (0.44 square meters) for each steam dryer.
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.
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.
EXAMPLE: For a bank of six (6) dryers, 2 unrestricted openings measuring 3 feet by 4 feet (12 square feet
[0.91 meters by 1.22 meters] [1.11 square meters]) are 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.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
14
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: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN
CREATE A POTENTIAL FIRE HAZARD.
NOTE: When a dryer is exhausted separately, it is recommended that 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 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 should not
exceed 20 feet (6.09 meters). In the case of multiple (common) dryer venting, the distance from the last
dryer to the outside exhaust outlet should not exceed 20 feet (6.09 meters). The shape of the ductwork
is not so critical so long as the minimum cross-sectional area is provided. It is suggested that the use of 90º
turns be avoided; use 30º and/or 45º bends/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-sectional area of the ductwork must be increased in
proportion to the number of elbows used.
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.
IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct 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.
IMPORTANT: It is recommended that exhaust or booster fans not be used in the exhaust ductwork
system.
15
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 26
gauge (0.0195-inches [0.50 mm]) thick.”
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 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 the 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: The minimum duct size for a gas unit is 18-inches (45.72 cm) for a round duct
16-inches x 16-inches (40.64 cm x 40.64 cm) for a square duct and for a steam unit
20-inches (50.80 cm) for a round duct and 18-inches x 18-inches (45.72 cm x 45.72
cm) for a square duct. THE DUCT SIZE MUST NOT BE REDUCED
ANYWHERE DOWNSTREAM OF THE 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.).
16
It is suggested that the ductwork from each dryer not exceed 20 feet (6.09 meters) with no more than two
(2) elbows (excluding dryer connections). If the ductwork exceeds 20 feet (6.09 meters) or has numerous
elbows, the cross-sectional area of the ductwork must be increased in proportion to the length and number
of elbows in it. In calculating duct size, the cross-sectional 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 duct should be increased ten percent (10%) for each additional 15 feet (4.57 meters). Each 90º
elbow is equivalent to an additional 40 feet (12.19 meters), and each 45º elbow is equivalent to an additional
20 feet (6.09 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, ventilating, 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.
17
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 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.
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 the flow and should be spaced at least 55-3/4”
(141.61 cm) apart. The main duct should be tapered, with the diameter increasing before each individual
18-inch (45.72 cm) 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 three (3) dryers should be connected to one (1) main common duct.
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 20 show the minimum cross section area for multiple dryer round or
square venting. These figures must be increased 10 square inches (64.52 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-sectional 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 40 feet (12.19 meters) and each 45° elbow is equivalent to an additional 20
feet (6.09 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, ventilating, and air-conditioning (HVAC) firm should be
consulted for proper venting information.
IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct must be no less
than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.).
18
The 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 duct.
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

3. Piping/Connections
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 (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 Btu being supplied.
The dryer is provided with a 1-1/2” N.P.T. inlet pipe connection extending out the back area of the burner
box. The minimum pipe size (supply line) to the dryer is 1-1/2” N.P.T. For ease in 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 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 1-1/2” (3.81 cm)
pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure regulator must
be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches (29.9 mb) of
water column (W.C.) pressure.
NOTE: A consistent water column test 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” 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 gas and L.P. gas must be used.
IMPORTANT: Test ALL connections for leaks by brushing on a soapy water solution (liquid
detergent works well).
WARNING: NEVER TEST FOR LEAKS WITH A FLAME!!!
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 Btu being
supplied.
27
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 test of the gas supply 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, regulated air (80 psi ± 10 psi [5.51 bar ± 0.68 bar]). 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.

3. Installation Instructions
To ensure an adequate supply of steam is provided, be sure that the steam supply lines and steam return
lines are sized and laid out as stipulated in this manual. Inadequate steam supply lines and steam return
lines or improper steam plumbing will result in poor performance and can cause component failure. Clean,
dry steam must be provided to the dryer.
IMPORTANT: Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY.
a. The presence of the condensate in the steam supply line will cause water hammer and subsequent heat
exchanger (steam coil) failure. The steam supply connection into the main supply line must be made
with a minimum 10-inch (25.4 cm) riser. This will prevent any condensate from draining towards the
dryer.
29
b. The steam supply line to the dryer must include a 12-inch (30.48 cm) riser 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 line, return line, and drip trap return line.
This will allow the dryer to be isolated from the supply main and the return main if the dryer needs
maintenance work.
e. Install an inverted bucket steam trap and check valve at least 12-inches (30.48 cm) below the steam
coil as close to the coil as possible.
An inverted bucket steam trap with a capacity of 2,000 lb (907.18 kg) of condensate per hour @ 125 psi
(8.62 bar) is required for each dryer.
f. A 3/4-inch (19.05 mm) vacuum breaker should be installed. This will save energy and provide for the
safety of the operator and maintenance personnel.
g. Dryers with optional solenoid valve must be mounted with coil positioned directly above the valve body.
h. Water pockets in the supply line, caused by low points, will provide wet steam to the coil possibly
causing steam coil damage. ALL horizontal runs of steam supply piping should be pitched 1/4-inch
(6.35 mm) for every one foot (0.30 meters) back towards the steam supply header causing the condensate
in the line to drain to the header. Install a bypass trap in any low point to eliminate wet steam.
STEAM DAMPER SYSTEM

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 in front of the electric service relay box. (Refer to the bottom
illustration on page 32.)

c. No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 psi (5.51 bar)
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 ensure that correct and clean air pressure
is achieved.
5. Steam Damper System Operation
The steam damper as shown in the top illustration on page 32, 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 steam damper is in cool down mode as shown in
Diagram 2 at the top of page 32.

Although the steam damper operation was tested and adjusted prior to shipping at 80 psi (5.51 bar), steam
damper operation must be checked before the dryer is put into operation. Refer to the illustration above
for correct steam damper operation. If steam damper adjustment is necessary, locate the flow control
valve and make the necessary adjustments as noted below.
32
I. PREPARATION FOR OPERATION/START-UP
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. In the 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 pre-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. Check to be sure that the drive belts between the idler pulley and the motor pulley have been reconnected.
NOTE: The drive belts were disconnected at the factory prior to dryer shipment.
6. GAS MODELS – be sure that 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. Be sure the lint drawer is securely in place.
NOTE: LINT DRAWER MUST BE ALL THE WAY IN PLACE TO ACTIVATE THE
SAFETY SWITCH OTHERWISE THE DRYER WILL NOT START.
10. Rotate the basket (tumbler/drum) by hand to be sure it moves freely.
11. Check bolts, nuts, screws, terminals, and fittings for security.
12. GAS MODELS AND STEAM MODELS – check to ensure air supply (80 psi [5.51 bar]) is connected to
the dryer.
13. STEAM MODELS – check to ensure ALL steam shutoff valves are open.
14. STEAM MODELS – check steam damper operation.
15. Check basket (tumbler) bearing setscrews to ensure they are ALL tight.
33
J. PREOPERATIONAL TEST
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. Refer to the Operating Instructions for starting your particular model dryer.
4. Check to ensure that the basket (tumbler) starts in the clockwise (CW) direction. Additionally, check the
direction of the blower motor impellor (fan) to ensure that the blower motor impellor (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/pulley that drives the impellor/fan (squirrel cage) when viewed
from the back of the dryer must turn in the counterclockwise (CCW) direction,
otherwise the 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 from the lines.
2) The dryer is equipped with a Direct Spark Ignition (DSI) system, which has internal diagnostics. If
ignition is not established after three (3) attempts, the heat circuit 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 the “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.
34
IMPORTANT: There is no regulator provided in a liquid propane (L.P.) dryer. The water column
(W.C.) pressure must be regulated at the source (L.P. tank) or an external regulator
must be added to each dryer.
b. Steam Models
Check to ensure that the steam damper is functioning properly.
The steam damper should not “slam” (open or closed) when it reaches the end of (piston) travel.
Additionally, the steam damper should not bind and/or stop during travel. If either of these conditions
occur, the flow control must be adjusted. Refer to the bottom illustration on page 32 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 the dryer. The dryer should start but the heat circuit should not be
activated (on). If the heat (burner) does activate, shut the dryer off and make the necessary
adjustments.
7. Reversing basket (tumbler) dryers should never be operated with less than a 112 lb (51 kg) load (dry
weight), since the load’s weight affects basket (tumbler) coast time during a direction reversal command.
It is important that the basket (tumbler) come to a complete stop prior to starting in opposite direction.
Microprocessor Controller (computer) Dryer Models
a. Spin and dwell (stop) times are not adjustable in the Automatic Mode and have been preprogrammed
into the microprocessor controller (computer) for 150-seconds spin time in the forward direction and
120-seconds in the reverse direction with a 5-second dwell (stop) time.
b. Spin and dwell (stop) times are adjustable in the Manual (timed) Mode.
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.
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.
Microprocessor Controller (computer) Programs/Selections...
Each microprocessor controller (computer) has been preprogrammed by the factory with the most commonly
used parameter (program) selections. If computer changes are required, refer to the computer programming
manual, which was shipped with the dryer.

L. COMPRESSED AIR REQUIREMENTS
The dryer requires an external supply of compressed air (2.5 cfh [cubic feet per hour] @ 80 psi [0.07 cmh [cubic
meters per hour] @ 5.51 bar] for gas models and 3.25 cfh @ 80 psi [0.09 cmh @ 5.51 bar] for steam models).
For steam models, compressed air is necessary for the air operated steam damper. On both the steam models
as well as the gas models, compressed air is necessary/required for blower air jet operation...to clean lint from
the impellor/fan (squirrel cage).

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: REMOVE POWER FROM THE DRYER BEFORE PERFORMING ANY
MAINTENANCE IN THE DRYER (cleaning the lint drawers and both steam coil lint
screens are the only exceptions).
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.
CLEAN LINT FROM LINT DRAWER/SCREEN EVERY THIRD OR FOURTH LOAD.
NOTE: The frequency of cleaning the lint screens can best be determined from experience at each
location.
WEEKLY
Clean lint accumulation from the lint chamber, thermostat, and microprocessor temperature sensor (sensor
bracket) area.
WARNING: TO AVOID HAZARD OF ELECTRICAL SHOCK, DISCONTINUE
ELECTRICAL POWER SUPPLY TO THE DRYER.
41
STEAM DRYERS
Clean the steam coil fins. Suggest using compressed air and a vacuum cleaner with brush attachment.
NOTE: When cleaning steam coil fins, be careful not to bend the fins. If fins are bent, straighten by
using a fin comb, which is available from any local air-conditioning supply house.
90 DAYS
Remove lint from around basket (tumbler), drive motors, and surrounding areas. Remove lint from the gas valve
burner area with a dusting brush or vacuum cleaner attachment.
Impellor (fan/blower) shaft bearings should be lubricated using Shell Alvania grease NLGI 2 or its equivalent.
Generically, this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium
thickener and mineral base oil.
Check to make sure that the setscrews on the impellor/fan shaft bearings are tight.
NOTE: To prevent damage, avoid cleaning and/or touching the direct spark ignitor.
Remove lint accumulation from inside.
6 MONTHS
Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal
exhaust ducting.
NOTE: THE ACCUMULATION OF LINT IN THE EXHAUST DUCTWORK CAN
CREATE A POTENTIAL FIRE HAZARD.
NOTE: DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR.
CHECK CUSTOMER FURNISHED BACK DRAFT DAMPERS IN THE EXHAUST
DUCTWORK. INSPECT AND REMOVE ANY LINT ACCUMULATION, WHICH
CAN CAUSE THE DAMPER TO BIND OR STICK.
NOTE: A back draft damper that is sticking partially closed can result in slow drying and shut down of
the heat circuit safety switches or thermostats.
NOTE: When cleaning the dryer cabinet(s), avoid using harsh abrasives. A product intended for the
cleaning of appliances is recommended.
Check ALL V-belts for tightness and wear. Retighten, realign, or replace if required.
NOTE: V-belts should be replaced in matched sets (pairs).
42
B. ADJUSTMENTS
7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER
Inspect bolts, nuts, screws, (bearing setscrews), grounding connections, and nonpermanent gas connections
(i.e., unions, shutoff valves, and orifices). Fan (impellor) V-belts, along with the motor and drive belts should be
examined and replaced if necessary. Tighten loose V-belts when necessary. Complete operational check of
controls and valves. Complete operational check of ALL safety devices (i.e., door switches, lint drawer switch,
sail switch, burner, and hi-limit thermostats).
NOTE: Squirrel cage type fan (impellor) on the blower motor must be inspected and cleaned
every 6 months.
C. LUBRICATION
The fan shaft bearings and ALL the basket (tumbler) drive shaft and idler shaft bearings must be lubricated
every 3 months. Use Shell Alvania #2 grease or its equivalent. Lubrication is necessary or premature bearing
failure will be the result.
The motor bearings are permanently lubricated and DO NOT require to be serviced.
43
SECTION VII
MANUAL RESET BURNER HI-LIMIT INSTRUCTIONS
A. PHASE 7
This dryer was manufactured with a manual reset burner hi-limit thermostat, which is monitored by the Phase 7
computer. If the burner hi-limit is open prior to the start of the drying cycle, the dryer will start momentarily and
then shut down, the Phase 7 computer will display “BURNER HIGH LIMIT FAULT” with an audio indication.
If the burner hi-limit opens during a drying cycle, the Phase 7 computer will also display the same error code
described above, along with an audio indication. If the drum temperature is above 100° F (38° C), the dryer will
continue to run with no heat for 3 minutes or until the drum temperature has dropped below 100° F (38° C). The
clear/stop button on the Phase 7 keypad must be pressed to clear the error condition. The open burner hi-limit
must be reset “manually” prior to the start of the next cycle.
B. DUAL TIMER
This dryer was manufactured with a manual reset burner hi-limit thermostat. If the burner hi-limit 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
and will start or continue through the drying cycle with no heat. Manual reset hi-limit must be reset manually.
This hi-temperature condition may be caused due to a restricted exhaust, poor airflow, or improper burner
operation.
The location of the burner hi-limit is on the right side of the burner box, looking at the burner from the back of the
dryer.
WARNING: Discontinue power to dryer before attempting to reset hi-limit.

PROCEDURE FOR FUNCTIONAL CHECK
OF REPLACEMENT COMPONENTS
1. Microprocessor Controller (Computer) Board
a. Phase 7 Non-Coin Models
1) Upon completing installation of the replacement
microprocessor controller (computer) board,
reestablish power to the dryer.
2) Start the drying cycle by pressing any of the preset
cycles in letters A-F.
3) Verify that the applicable indicator lights on the
microprocessor controller (computer) board are
lit. (Refer to the illustration below.)
47
2. For Models with Direct Spark Ignition (DSI) Module (Type I)
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” (light emitting diode [L.E.D.] diagnostic
indicator 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 Models with DSI Module (Type II)
Theory of Operation:
Start the drying cycle. When the gas burner ignites within the
chosen trial for ignition time (8-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” (a red L.E.D. diagnostic indicator will
flash).
An unlit red L.E.D. diagnostic indicator indicates normal operation.
A lit green L.E.D. diagnostic indicator indicates dryer controller is calling for heat and that ALL interlocks
have been satisfied.
48
SECTION XI
SENSOR ACTIVATED
FIRE EXTINGUISHING (S.A.F.E.) SYSTEM
The exclusive S.A.F.E. system will extinguish fires that may start in the drying basket (tumbler). A series of
sensors positioned throughout the basket (tumbler) and interfaced with the microprocessor will trigger the S.A.F.E.
system water jet(s) to quickly extinguish the flames. The water jet(s) remain on for 2 minutes and will automatically
activate again if a fire condition remains or reignites. While the water jet(s) are activated, the basket (tumbler)
will jog to move the water throughout the load. The microprocessor will display that the system was activated
and will continue to display until the dryer is attended to.
BEFORE YOU START, CHECK LOCAL CODES AND PERMITS
Call your local water company or the proper municipal authority for information regarding local codes.
IMPORTANT: It is your responsibility to have ALL plumbing connections made by a qualified
professional to assure that the plumbing installation is adequate and conforms to local,
state, and federal regulations or codes.
IMPORTANT: It is the installer’s or owner’s responsibility to see that the necessary or required
water, water pressure, pipe size, or connections are provided. The manufacturer
assumes no responsibility if the S.A.F.E. system is not connected, installed, or
maintained properly.
INSTALLATION
1. Requirements
The S.A.F.E. system must be supplied with a minimum water pipe size of 1/2-inch and be provided with 40
psi ± 20 psi (2.75 bar ± 1.37 bar) of pressure. For use of optional manual bypass, a second source with the
same piping and pressure requirements is required.
Flexible 1/2 feeds must be provided to avoid damage to electric water solenoid valve by vibration.
IMPORTANT: Flexible supply line/coupling must be used. Solenoid valve failure due to hard
plumbing connections WILL VOID WARRANTY.
If the rear area of the dryer, or the water supply is located in an area where it will be exposed to cold/
freezing temperatures, provisions must be made to protect these water lines from freezing.
WARNING: If the water in the supply line or water solenoid valve freezes, the S.A.F.E. system will
be INOPERATIVE!!
IMPORTANT: Appliance is to be connected to the water mains using a new hose set and the old
hose set should not be reused.
49
2. Water Connections:
The water connection is made to the 3/4”-11.5 NH
hose adaptor of the electric water solenoid valve,
located at the rear upper midsection of the dryer (refer
to the photo).
The water solenoid valve has a 3/8” M.P.T. connection
supplied with a 3/4”-11.5 NH hose adaptor to provide
the minimum 1/2-inch supply (feed) line. Flexible
supply line/coupling must be used in an effort to
avoid damaging the electric water solenoid valve.
NOTE: The 3/4”-11.5 NH is a standard hose coupling screw thread. It is not to be confused with
3/4” N.P.T. The sealing of an NH connection is made with a washer opposed to the mating
threads of an N.P.T. assembly. The two (2) thread designs are not compatible.
IMPORTANT: Flexible supply line/coupling must be used. Solenoid valve failure due to hard
plumbing connections WILL VOID WARRANTY. It is recommended that a filter
or strainer be installed in the water supply line.
Typical water supply...
50
OPTIONAL MANUAL BYPASS
Provisions are made in the dryer S.A.F.E. system for the installation of an optional manual bypass. Depending
on the model dryer, the connections for the manual bypass are made at the “T” or “three way” fitting, located in
the outlet supply side of the water solenoid valve. The use and connections of this manual bypass are at the
option or discretion of the owner.
The water connection for the manual bypass is made to the “T” or “three way” fitting, which has a 3/8” F.P.T.
and a coupling must be used to provide the minimum 1/2” supply (feed) line.
If the rear area of the dryer, or the water supply is located in an area where it will be exposed to cold/freezing
temperatures, provisions must be made to protect these water lines from freezing.
WARNING: If the water in the supply line or water solenoid valve freezes, the S.A.F.E. system will
be INOPERATIVE!!
The manual ball cock shutoff valve must be located outside of the dryer at a distance from the dryer where it
is easily accessible.
3. Electrical Requirements
No independent external power source or supply connection is necessary. The 24 volt power to operate the
S.A.F.E. system is accomplished internally in the dryer (from the dryer controls).
WARNING: Electrical power must be provided to the dryer at ALL times. If the main electrical
power supply to the dryer is disconnected, the S.A.F.E. system is INOPERATIVE!!
51
S.A.F.E. SYSTEM THEORY OF OPERATION
While the dryer is in an idle state or 20-seconds after the heat turns off, the Phase 7 control monitors the
S.A.F.E. system probe located in the top of the basket (tumbler) chamber and records the minimum temperature.
If the minimum recorded S.A.F.E. system probe temperature is no less than 120° F (48° C) and the control
detects a 50° rise in temperature, this will be the trip point and the S.A.F.E. system routine will activate.
While a drying cycle is in process and the heat has turned on at least once, the Phase 7 control monitors the
exhaust temperature transducer. If the drying cycle temperature set point is set greater than 160° F (71° C) and
the control detects an exhaust temperature rise 25° F greater than set point, this will be the trip point and the
S.A.F.E. system routine will activate. If set point is below 160° F (71° C) the trip point will be 185° F (85° C).
Once the S.A.F.E. system routine is activated, water will be injected into the basket (tumbler) chamber. Anytime
water is being injected into the basket (tumbler); the basket (tumbler) drive will turn the load for 1-second every
15-seconds. This process will continue for a minimum of 2 minutes. After 2 minutes has elapsed, the control will
check if the temperature remained above trip point, if so water will remain on. The control will continue to check
if temperature is above trip point every 30-seconds. If the water has been on for a constant 10 minutes, the
water will be turned off regardless of the temperature. If the temperature has dropped below trip point, the
control will turn off the water prior to 10 minutes.
SYSTEM RESET
After the microprocessor determines that the situation is under control and shuts the water being injected into the
basket (tumbler) off, the microprocessor display will read “S.A.F.E. System activated,” and the horn/tone will
sound until reset manually.
To reset the microprocessor once the control displays “S.A.F.E. System activated,” press the red “STOP”
on the keypad.
key
NON-COIN S.A.F.E. SYSTEM CHECK PROCEDURE
The operation of the water solenoid valve can be tested to ensure that the water supply system and valve are
functional. Before attempting system check, be sure that ALL water supply shutoff valves to the dryer are in
the OPEN position, and the dryer must be in the “READY” mode where no cycle is loaded or in progress.
The procedure is as follows:
1. Press and hold the red “STOP” key (while in “READY” mode and no cycle in progress).
2. Press and hold the “A” key.
3. Water valve will open and water will be dispensed into basket (tumbler) area as long as both keys are held.
IMPORTANT: This is a test function only and the keys should be held and system activated for only
a second or so, otherwise water will accumulate in various places in the dryer.
