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 have reimbursed and becomes extremely
difficult when more than a day or two passes after the freight was delivered. It is your responsibility to file
freight claims. Dryer/parts damaged in transit cannot be claimed under warranty.
5. Freight claims are the responsibility of the consignee, and ALL claims must be filed at the receiving end.
ADC assumes no responsibility for freight claims or damages.
6. If you need assistance in handling the situation, please contact the ADC Traffic Manager at (508)
678-9000.
IMPORTANT: The dryer must be transported and handled in an upright position at ALL times.

11
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions must be made of noncombustible materials and must be located a minimum of
12-inches (30.48 cm), 18-inches (45.72 cm) or more is recommended for ease of installation, maintenance, and
service above the dryer outer top, except along the front of the dryer which may be partially closed in if desired.
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. The bulkhead facing must not be closed in
ALL the way to the top of the dryer. A 1-inch (2.54 cm) clearance is required.
NOTE: Allowances must be made for opening the control door.
Dryers may be positioned sidewall to sidewall. However, a 1/16” (1.587 mm) minimum allowance must be
made for the opening and closing of the control door and the lint door. It is suggested that the dryer be positioned
about 2 feet (0.61 meters) away from the nearest obstruction for ease of installation, maintenance, and service
(to be measured from the back guard). Refer to the illustration above for details.
NOTE: Air considerations are important for proper and efficient operation.
IMPORTANT: Even though a minimum of only 12-inches (30.48 cm) is required behind the dryer,
18-inches (45.72 cm) or more is suggested (especially when vertical venting is used).
The additional clearance is advantageous for ease of installation and service.
IMPORTANT: 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, a 1/16” (1.587 mm) minimum allowance is required
between dryers (or wall) for ease of installation and maintenance. Allowances must
be made for the opening and closing of the control door and the lint door.
12
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 ensure proper performance of each dryer. An
unrestricted source of air is necessary for each dryer. An airflow of 1,200 cfm (cubic feet per minute) (33.98
cmm [cubic meters per minute]) must be supplied to each gas dryer. As a general rule, an unrestricted air
entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.41 square meters) is required for
each dryer. The dryer must be installed with provisions for adequate combustion and make-up air supply.
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 separate make-up air openings 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 four (4) dryers, two (2) unrestricted openings measuring 2 feet by 1-1/2 feet (0.60
meters by 0.45 meters) (6 square feet [0.56 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.
13
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-limit 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 DUCTWORK CAN
CREATE A POTENTIAL FIRE HAZARD.
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.
Horizontal Venting:
When single dryer venting is used, the length of the ductwork from the dryer to the outside exhaust outlet
must not exceed 15 feet (4.6 meters). The minimum diameter of this ductwork must be at least
10-inches (25.4 cm). In the case of multiple (common) dryer venting, the distance from the last dryer to the
outside exhaust outlet must not exceed 15 feet (4.6 meters). The shape of the ductwork is not critical as
long as the minimum cross-sectional area is provided. It is suggested that the use of 90° turns be avoided;
use 30° and/or 45° angles instead. The radius of the elbows should preferably be 1-1/2 times the
diameter of the duct. Including 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. 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.
Vertical Venting:
When single dryer venting is used, the length of the ductwork from the dryer to the outside exhaust outlet
must not exceed 20 feet (6.1 meters). The minimum diameter of this ductwork must be at least
12-inches (30.48 cm). In the case of multiple (common) dryer venting, the distance from the last dryer to
the outside exhaust outlet must not exceed 20 feet (6.1 meters). The shape of the ductwork is not critical
as 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 instead. The radius of the elbows should preferably be 1-1/2 times the
diameter of the duct. 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: It is recommended that exhaust or booster fans not be used in the exhaust ductwork
system.
14
NOTE: As per the National Fuel Gas Code, “Exhaust ducts for Type 2 clothes dryers shall be
constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent
in strength and corrosion resistance to ducts made of galvanized sheet steel not less than
0.0195-inches (26 gauge [0.05 mm]) thick.”
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.).
IMPORTANT: Minimum ductwork diameter for horizontal venting is 10-inches (25.4 cm) and for
vertical venting the minimum is 12-inches (30.48 cm).
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.
2. Single Dryer Venting
When 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 as long as the minimum cross-sectional area is
provided.
15
IMPORTANT: Minimum duct size for a dryer that is vented horizontally is 10-inches (25.4 cm) for a
round duct or an equivalent of 80 square inches (516.3 square centimeters). THE
DUCT SIZE MUST NOT BE REDUCED ANYWHERE DOWNSTREAM OF
THE DRYER.
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.
IMPORTANT: Minimum duct size for a dryer that is vented vertically is 12-inches (30.48 cm) for a
round duct or an equivalent of 120 square inches (774.2 square centimeters). THE
DUCT SIZE MUST NOT BE REDUCED ANYWHERE DOWNSTREAM OF
THE DRYER.
IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be
increased to an extent. When the ductwork approaches the maximum limits 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.
16
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. 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 Btus being supplied.
The dryer is provided with a 3/4” N.P.T. inlet pipe connection located at the right side of the base of the
dryer. The minimum pipe size (supply line) to the dryer is 3/4” 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.
24
Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-inch (19.050
mm) 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 water column test pressure of 3.5 inches (8.7 mb) for natural gas and 10.5 inches (26.1 mb)
for liquid propane (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 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 test of the gas supply system at test pressures equal to or less
than 1/2 psig (3.5 kPa).
25
H. 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 230/240 VAC the supply voltage must match the electric service exactly.
3. Check to ensure that the dryer is connected to the type of heat/gas indicated on the dryer data label.
4. 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 ensure that this important safety control is functioning.
5. 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 ensure that they are closed and secured in place.
8. Be sure the lint door is securely in place.
9. Rotate the basket (tumbler/drum) by hand to be sure it moves freely.
10. Check bolts, nuts, screws, terminals, and fittings for security.
11. Check basket (tumbler) bearing setscrews to ensure they are ALL tight.
26
I. PREOPERATIONAL TESTS
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test
should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or
due to marginal location (installation) conditions.
1. Turn on electric power to the dryer.
a. Open ALL shutoff valves.
2. Refer to the Operating Instructions for starting your particular model dryer.
a. 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.
b. A gas pressure test should be taken at the gas valve pressure tap of each dryer to ensure that the
water column (W.C.) pressure is correct and consistent.
c. If the dryer is equipped with a Direct Spark Ignition (DSI) system, the DSI control module has internal
diagnostics. If ignition is not established within three (3) attempts, the heat circuit in the DSI control
module will “LOCKOUT” until manually reset. To reset the DSI system, open and close the main door
and restart the dryer.
NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.
NOTE: Water column pressure requirements (measured at the pressure tap of the gas valve body)...
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.
3. Make a complete operational check of ALL safety related circuits:
a. Door switch(es)
b. Hi-Limit thermostats
c. Sail switch
NOTE: To check for proper sail switch operation, open the main door and while holding main door
switch plunger in, start the dryer. Dryer should start but heat circuit should not be activated
(on). If the heat system is activated, the sail switch is improperly adjusted and must be
adjusted by bending the actuator arm of the sail switch toward the burner box. If the actuator
arm is bent to far toward the burner box of the dryer, the dryer may not have heat when
needed. After any adjustment to the sail switch, the above procedure must be repeated to
verify proper operation of the sail switch.
27
4. The dryer should be operated through one (1) complete cycle to ensure that no further adjustments are
necessary and that ALL components are functioning properly.
BASKET (TUMBLER) COATING
The basket (tumbler) is treated with a protective coating. We suggest dampening old garments or cloth material
with a solution of water and nonflammable mild detergent and tumbling them in the basket (tumbler) to remove
this coating.
5. Make a complete operational check of ALL operating controls.
a. For microprocessor controller (computer) models check programs/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.
6. Check the electric service phase sequence (3-phase [3ø] models only). While the dryer is operating, check
to see if the blower wheel (impellor/fan) is rotating in the proper direction. Looking from the front, the
blower wheel (impellor/fan) should spin in the clockwise (CW) direction. If it is, the phasing is correct. If
the phasing is incorrect, reverse two (2) of the three (3) leads at connections L1, L2, and L3 of the power
supply to the dryer.
IMPORTANT: If the blower wheel (impellor/fan) is rotating in the wrong direction, this will not only
drastically reduce drying efficiency, but it can also cause premature component failure.
7. Reversing basket (tumbler) dryers should never be operated with less than a 50 lb (22.7 kg) load (dry
weight), since the load’s weight effects the basket (tumbler) coast time during a direction reversal command.
It is important that the basket (tumbler) comes to a complete stop prior to starting in opposite direction.
a. Microprocessor Models
1) Spin times and dwell (stop) times are not adjustable in the Automatic Mode and have been
preprogrammed into the microprocessor controller (computer) for 120-seconds spin time and a
5-second dwell (stop) time.
2) Spin times and dwell (stop) times are adjustable in the Manual (timed) Mode.
b. Dual Timer Models
1) Both dwell (stop) time and basket (tumbler) spin time are adjustable (refer to the illustration on
page 35).
8. Check to ensure that ALL setscrews (i.e., basket [tumbler] drive, idler, etc.) are tight.
28
J. PREOPERATIONAL INSTRUCTIONS
1. To start the dryer:
a. Microprocessor Controller (Computer) Dryers...
1) The light emitting diode (L.E.D.) display will read “REAdY” (meaning no cycle in progress).
2) Press the letter on the keyboard (touch pad) corresponding to the cycle desired (i.e., key “E”)...

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, inspect the exhaust ducting and remove any lint buildup.
SUGGESTED CLEANING SCHEDULE
EVERY THIRD OR FOURTH LOAD
Clean the lint screen every third or fourth load. A clogged lint screen will cause poor dryer performance. The
lint screen is located behind the lint door in the base of the dryer. Open the lint door, brush the lint off the lint
screen, and remove the lint. Inspect the lint screen and replace if torn.
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.
33
90 DAYS
1. Remove lint from around basket (tumbler), drive motors, and surrounding areas.
2. Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment.
3. Clean any lint accumulation in and around both the blower and drive motor casing openings.
NOTE: To prevent damage, avoid cleaning or touching the hot surface ignitor assembly.
EVERY 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 shutdown of
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.
B. ADJUSTMENTS
7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER
Inspect bolts, nuts, screws, (bearing setscrews), grounding connections, and nonpermanent gas connections
(unions, shutoff valves, and orifices). 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 switches, lint door switch, sail switch, burner
and hi-limit thermostats).
C. LUBRICATION
The motor bearings, idler bearings, and, under normal/most conditions, the basket (tumbler) bearings are permanently
lubricated. It is physically possible to relubricate the basket (tumbler) bearings if you choose to do so even
though this practice is not necessary. Use Shell Alvania #2 grease or its equivalent. The basket (tumbler)
bearings used in the dryer DO NOT have a grease fitting. Provisions are made in the bearing housing for the
addition of a grease fitting, which can be obtained elsewhere, or from ADC by ordering kit P/N 882159 (includes
two [2] fittings).

SECTION IX
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 by pressing any of the preset cycles in letters A-F.
c. Verify that the applicable indicator lights on the back side of the microprocessor controller (computer)
board are lit. (Refer to the illustration below.)
38
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” (light emitting diode [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.
39
SECTION X
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 keyboard (touch pad) 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.
40
SECTION XI
FIRE SUPPRESSION SYSTEM (F.S.S.)
F.S.S. In Action
The exclusive Fire Suppression System (F.S.S.) 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 F.S.S. 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.
We have tried to make this manual as complete as possible and hope you will find it useful. ADC
reserves the right to make changes from time to time, without notice or obligation, in prices,
specifications, colors, and material, and to change or discontinue models.

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 ensure that the plumbing installation is adequate and conforms to local,
state, and federal regulations or codes.
IMPORTANT: It is the installation or owners responsibility to see that the necessary or required
water, water pressure, pipe size, or connections are provided. Manufacturer assumes
no responsibility if the F.S.S. is not connected, installed, or maintained properly.
INSTALLATION
1. Requirements
The F.S.S. 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 F.S.S. will be
INOPERATIVE!!
IMPORTANT: Appliance is to be connected to the water mains using a new hose-set and the old
hose-sets should not be reused.
42
2. Water Connections:
The water connection is made to the 3/4”-11.5 NH
hose adapter 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 adapter 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...
43
OPTIONAL MANUAL BYPASS
Provisions are made in the dryer’s F.S.S. 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 “four 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 “four 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 F.S.S. 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
F.S.S. 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 F.S.S. is INOPERATIVE!!
44
F.S.S. 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 F.S.S.
probe located in the top of the basket (tumbler) chamber and records the minimum temperature. If the minimum
recorded F.S.S. 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 F.S.S. 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
F.S.S. routine will activate. If set point is below 160° F (71° C) the trip point will be 185° F (85° C).
Once the F.S.S. 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 “Fire Suppression System activated,” and the horn/
tone will sound until reset manually.
To reset the microprocessor once the control displays “Fire Suppression System activated,” press the red
key on the keyboard (touch pad).
NON-COIN F.S.S. 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.
