NOTE: Component failure due to dry cleaning solvent
fumes will void the warranty.
Exhaust Requirements _______________
General Exhaust Ductwork Information
Fresh Air Supply Requirements ______
When the dryer is operating, it draws in room air, heats it,
passes this air through the 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. 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.
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) switch, burner hilimit, or tumbler hi-heat thermostat. 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.
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.*
When dryers are exhausted into a multiple (common)
exhaust line, each dryer must be supplied with a back draft
damper.*
* Models manufactured as of September 24, 2001, have a damper in the dryer
as a standard item.
IMPORTANT: Exhaust back pressure measured by a
manometer at each tumbler exhaust duct area must be no
less than 0 and must not exceed 0.3 in wc (0.74 mb).
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. It is suggested that the use of
90° turns in ducting 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. The shape of the exhaust
ductwork is not critical as long as the minimum cross-sectional
area is provided.
IMPORTANT: It is recommended that exhaust or booster
fans not be used in the exhaust ductwork system.
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.”
EXAMPLE: For a bank of 6 gas dryers, 2 openings measuring
3 feet by 3 feet (0.91 meters by 0.91 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.
12
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.
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 in wc (0.74 mb).
American Dryer Corp.
113335 - 12
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.
Outside Ductwork Protection
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.
When venting vertically, the ductwork from each dryer must
be a minimum of 16-inches (40.64 cm) and not exceed 20
feet (6.1 meters) with no more than 3 elbows (including dryer
connections and outside exhaust outlets). If the ductwork
exceeds 20 feet (6.1 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.
IMPORTANT: For extended ductwork runs, the cross
section area of the duct can only be increased to an
extent. When the ductwork approaches the maximum
limits as noted in this manual, a professional HVAC firm
should be consulted for proper venting information.
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 inches (122.87 cm) apart. The main duct should be
tapered, with the diameter increasing before each individual
14-inch (35.56 cm) minimum 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.*
No more than 4 dryers should be connected to 1 main
common duct.
* Models manufactured as of September 24, 2001, have a damper in the dryer
as a standard item.
Single Dryer Venting
IMPORTANT: Minimum duct size for a gas, electric, or
steam dryer with a vertical run and not more than 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.
The illustrations on the following page show the minimum
cross-sectional area for multiple dryer round or square
venting. These figures must be increased in proportion if the
length of ducting from the last dryer to where it exhausts to
the outdoors is over 20 feet (6.1 meters) or has more than 1
elbow in it.
ML-130
IMPORTANT: For extended ductwork runs, the crosssectional area of the ductwork can only be increased to an
extent. When the ductwork approaches the maximum
limits as noted in this manual, a professional HVAC firm
should be consulted for proper venting information.
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 in wc (0.74 mb) for the ML-130 model.
ML-130DR Single Dryer Venting
When venting horizontally, the ductwork from each dryer must
be 14-inches (35.56 cm) and not exceed 20 feet (6.1 meters)
with no more than 1 elbow (including dryer connections and
outside exhaust outlets). If the ductwork exceeds 20 feet
(6.1 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.

Installation Instructions
To ensure that 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 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.
The pressure 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 within a minimum 12-inch (30.48
cm) riser. This will prevent any condensate from draining
towards the dryer.
Steam Information ____________________
It is your responsibility to have all steam plumbing connections
made by a qualified professional to ensure 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 of 0.75 cfh (0.02 cmh) @ 80
psi +/- 10 psi (5.51 bar +/- 0.68 bar). Refer to Steam
Damper Air System Connections on the following page.
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.

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.
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.
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.
Install an inverted bucket steam trap and check valve for
each unit at least 12-inch (30.48 cm) below steam coil as
close to the coil as possible.
A trap with a capacity of 1,200 lb (544 kg) of condensate per
hour at 125 psi (8.61 bar) is needed for each unit.
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.
Dryers with optional solenoid valve must be mounted with
coil positioned directly above the valve body.
The supply and return lines should be insulated. This will
save energy and provide safety for the operator and
maintenance personnel.
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.

The steam damper, as shown in the illustration below, 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
tumbler, allowing a rapid cool down.

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 bar), steam damper operation must
be checked before the dryer is put into operation. Refer to
the previous page 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.
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.
Turn on electric power to the dryer.
Make sure the main door is closed and the lint drawer is
securely in place.
Refer to the Operating Instructions for starting your particular
model dryer.
Check to ensure that the tumbler starts in the clockwise
direction. Additionally, check the direction of the blower motor
(impellor/fan) to ensure that the blower motor (impellor/fan)
rotates in the clockwise direction as viewed from the front. If
it is, the phasing is correct. If the phasing is incorrect, reverse
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 direction,
otherwise dryer efficiency will be drastically reduced and
premature component failure can result.
Preparation for Operation ____________
The following items should be checked before attempting to
operate the dryer:
Read all “CAUTION,” “WARNING,” and “DIRECTION” labels
attached to the dryer.
Check incoming supply voltage to be sure that it is the same
as indicated on the dryer data label. In case of 208 VAC or
230/240 VAC, the supply voltage must match the electric
service exactly.
GAS MODELS – check to ensure that the dryer is connected
to the type of heat/gas indicated on the dryer data label.
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
ensure that this important safety control is functioning.
GAS MODELS – be sure that all gas shutoff valves are in the
open position.
Be sure all back panels (guards) and electric box covers have
been replaced.
Check all service doors to ensure that they are closed and
secured in place.
Heat Circuit Operational Test
Gas Models
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.
If the dryer is equipped with a DSI system, the DSI control
module has internal diagnostics. If ignition is not established
within 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.
If the dryer is equipped with an HSI system, the HSI control
module has internal diagnostics. If ignition is not established
after the first attempt, the heat circuit in the HSI control module
will “LOCKOUT” until manually reset. To reset the HSI 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.
Once ignition is established, a gas pressure test should be
taken at the gas valve pressure tap of each dryer to ensure
that the water column pressure is correct and consistent.
NOTE: Water column pressure requirements (measured at
the gas valve pressure tap)...
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.
Rotate the tumbler by hand to be sure it moves freely.
Natural Gas ........ 3.5 in wc (8.7 mb).
L.P. Gas ............. 10.5 in wc (26.1 mb).
STEAM MODELS – check to ensure air supply (80 psi [5.51
bar]) is on the dryer.
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.
STEAM MODELS – check to ensure all steam shutoff valves
are open.
Electric Models
Check bolts, nuts, screws, terminals, and fittings for security.
STEAM MODELS – check steam damper operation.
Check tumbler bearing setscrews to ensure they are all tight.
20
Check the oven contactor(s) to ensure that the electric oven
is cycling properly.
American Dryer Corp.
113335 - 12
Steam Models
Check to ensure that steam damper is functioning properly.
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 bottom illustration on page
19 for air adjustment instructions.)
Make a complete operational check of all safety related
circuits (i.e., lint drawer switch and sail switch on gas models).
Reversing tumbler dryers should never be operated with less
than an 80 lb (36.3 kg) load (dry weight), since the load’s
weight affects tumbler coast time during a direction reversal
command. It is important that the tumbler come to a complete
stop prior to starting in opposite direction.

Steam Dryers
Routine Maintenance _________________
Clean the steam coil fins. We suggest using compressed air
and a vacuum cleaner with brush attachment.
To avoid the hazard of electrical shock,
discontinue electrical supply to the dryer.
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

Procedure for Functional Check
of Replacement Components ________
Microprocessor Controller (Computer)
Board
A steady L.E.D. indicator indicates normal operation.
No L.E.D. indicator indicates a power or an internal failure
has occurred.
Upon completing installation of the replacement
microprocessor controller (computer) board, reestablish
power to the dryer.
Start the drying cycle by pressing any of the preset cycles in
letters A-F.
For Models with DSI Module (Type II)
Verify that the applicable indicator lights on the
microprocessor controller (computer) board are lit. (Refer to
the illustration below.)
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 3 retries/trials (the initial try and 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.
For Models with 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 3 retries/trials (the initial try and 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. diagnostic indicator flashes).

Manual Reset
Burner Hi-Limit Instructions _________
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.
Fire Suppression System _____________

Requirements
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.
The connection point to the electric water solenoid valve is a
3/4-11.5 NH, the F.S.S. must be supplied with a minimum
water pipe size of 1/2” 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.
This hi-temperature condition may be caused due to a
restricted exhaust, poor airflow, or improper burner operation.
Flexible 1/2 feeds must be provided to avoid damage to
electric water solenoid valve by vibration.
The location of the burner hi-limit is on the right side of the
burner box, looking at the burner from the front of the dryer.
! WARNING
▲
Discontinue power to dryer before attempting to
reset hi-limit.
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 set should
not be reused.
Water Connection
The water connection is made to the 3/4-11.5 NH bushing
located at the rear upper right area of the dryer. Flexible
supply line/coupling must be used in effort to avoid damage
to electric water solenoid valve.
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.
