building.
113202 - 10
www.amdry.com
11
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 3 feet (0.91 meters) from the nearest obstruction (i.e., wall) for ease of installation,
maintenance, and service. Bulkheads and partitions should be made from noncombustible materials. The
clearance between the bulkhead header and the dryer must be a minimum of 4-inches (10.16 cm) and must not
extend more than 4-inches (10.16 cm) to the rear of the dryer front. The bulkhead facing must not be closed in
ALL the way to the top of the dryer. A 2-inch (5.08 cm) clearance is required.
NOTE: Bulkhead facing should not be installed until after dryer is in place. Ceiling area must be
located a minimum of 12-inches (30.48 cm) above the top of the dryer. Even though a
minimum of only 12-inches (30.48 cm) is required, 18-inches (45.72 cm) or more is suggested
for steam dryers and especially in cases where sprinkler heads are over the dryers.
NOTE: When fire sprinkler systems are located above the dryers, a minimum of 18-inches (45.72 cm)
above the dryer console (module) is suggested. Dryers may be positioned sidewall to
sidewall; however, 1 or 2-inches (2.54 cm or 5.08 cm) is suggested between dryers (or wall)
for ease of installation and maintenance. Allowances must be made for the opening and
closing of the control and lint doors.
D. FRESH AIR SUPPLY REQUIREMENTS
When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and
exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the
make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail
switch “fluttering” problems may result, as well as premature motor failure from overheating.
12
American Dryer Corp.
113202 - 10
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 2,100 cfm (cubic feet per minute) (59.5 cmm
[cubic meters per minute]) must be supplied to 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 dryer.
To compensate for the use of registers or louvers used over the openings, this make-up air area must be
increased by approximately thirty-three percent (33%). Make-up air openings should not be located in an area
directly near where exhaust vents exit the building.
It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are
acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL
the dryers. The dryer must be installed with provisions for adequate combustion and make-up air supply.
EXAMPLE: For a bank of six (6) gas dryers, two (2) openings measuring 3 feet by 3 feet (0.91 meters by 0.91
meters) 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.
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.
113202 - 10
www.amdry.com
13
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK COULD
CREATE A 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 exhaust ductwork should be laid out in such a way that the ductwork travels as directly as possible to
the outdoors with as few turns as possible. Single or independent dryer venting is recommended. When
single dryer venting is used, the ductwork from the dryer to the outside exhaust outlet must not 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 must not exceed 20 feet (6.09 meters). The shape of the ductwork is not critical as
long as the minimum cross section area is provided. 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. Excluding basket (tumbler) dryer elbow connections or elbows used for outside
protection from the weather, no more than two (2) elbows should be used in the exhaust duct run. If more
than two (2) elbows are used, the cross section area of the ductwork must be increased in proportion to
number of elbows added.
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.”
ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,
which will collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is
connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.
Additionally, inspection doors should be installed at strategic points in the exhaust ductwork for periodic
inspection and cleaning of lint from the ductwork.
To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should
be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it
should be protected from the weather by using a 180° turn to point the opening downward. In either case,
allow at least twice the diameter of the duct between the duct opening and the nearest obstruction (i.e., roof
or ground level).
IMPORTANT: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must
be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column
(W.C.).
NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible
materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around).
The duct must be centered within this opening.

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.
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 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 section area is provided.
IMPORTANT: Minimum duct size for a gas, electric, or steam dryer with a vertical run and not more
than three (3) elbows (including dryer connection and outside outlets) is 16-inches
(40.64 cm) for a round duct or 14-1/2” by 14-1/2” (36.83 cm by 36.83 cm) for a
square duct. DUCT SIZE MUST NOT BE REDUCED ANYWHERE
DOWNSTREAM OF DRYER.
IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust
duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water
column (W.C.).
It is suggested that the ductwork from each dryer (minimum 14-inches [35.56 cm]) not exceed 20 feet (6.09
meters) with no more than three (3) elbows (including dryer connections and outside exhaust outlets). If the
ductwork exceeds 20 feet (6.09 meters) or has numerous elbows, the cross section area of the ductwork
must be increased in proportion to the length and number of elbows in it. In calculating duct size, the cross
section area of a square or rectangular duct must be increased by twenty percent (20%) for each additional
20 feet (6.09 meters). The diameter of a round exhaust duct should be increased ten percent (10%) for
each additional 15 feet (4.57 meters). Each 14-inch (35.56 cm) 90° elbow is equivalent to 30 feet (9.14
meters) and each 16-inch (40.64 cm) 90° elbow is equivalent to 36 feet (10.97 meters).
113202 - 10
www.amdry.com
15
IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased
to an extent. Maximum proportional ductwork runs cannot exceed 20 feet (6.09
meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows.
When the ductwork approaches the maximum limits as noted in this manual, a
professional heating, ventilating, and air-conditioning (HVAC) firm should be
consulted for proper venting information.
3. Multiple Dryer (Common) Venting
If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be
channeled into a “common main duct.” The individual ducts should enter the bottom or side of the main duct
at an angle not more than 45° in the direction of airflow and should be spaced at least 46-1/8” (117.16 cm)
apart. The main duct should be tapered, with the diameter increasing before each individual 14-inch (35.56
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 four (4) dryers should be connected to one (1) main common duct.
The main duct may be any shape or cross-sectional area, as long as the minimum cross section area is
provided. The illustration on the following page shows the minimum cross-section area for multiple dryer
round or square venting. These figures must be increased 10 square inches (64.51 square centimeters)
when rectangular main ducting is used, and the ratio of duct width to depth should not be greater than
3-1/2 to 1. These figures must be increased proportionally if the main duct run to the last dryer to where it
exhausts to the outdoors is unusually long (over 20 feet [6.09 meters]) or has numerous elbows (more than
two [2]) in it. In calculating ductwork size, the cross-section area of a square or rectangular duct must be
increased twenty percent (20%) for each additional 20 feet (6.09 meters). The diameter of a round exhaust
must be increased ten percent (10%) for each additional 20 feet (6.09 meters). Each 90° elbow is equivalent
to an additional 15 feet (4.57 meters).

IMPORTANT: No more than three (3) dryers should be connected to one (1) main common duct.
NOTE: The individual ducts traveling from each dryer up to the common duct must not travel more
than 15 feet (4.57 meters) including the 45° entry elbow into the common duct and the 90°
elbow outside the dryer allowing the duct to travel vertically. These individual ducts must be a
minimum of 14-inches (35.56 cm). If the ductwork exceeds these limits, the ductwork size
must be increased proportionally according to the number of elbows and the length that has
been added.

3. Piping and 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 (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” N.P.T. inlet pipe connection extending out the back area of the burner box.
The minimum pipe size connection (supply line) to the dryer is 1” diameter. For ease of servicing, the gas
supply line of each dryer must have its own shutoff valve.
The size of the main gas supply line (header) will vary depending on the distance this line travels from the
gas meter or, in the case of L.P. gas, the supply tank, other gas-operated appliances on the same supply line,
etc. Specific information regarding supply line size should be determined by the gas supplier.
NOTE: Undersized gas supply piping can create a low or inconsistent pressure, which will result in
erratic operation of the burner ignition system.
Consistent gas pressure is essential at ALL gas connections. It is recommended that a 1-inch (2.54 cm)
pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure 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.
IMPORTANT: A water column pressure of 3.5 inches (8.7 mb) for natural gas and 10.5 inches
(26.1 mb) for L.P. dryers is required at the gas valve pressure tap of each dryer for
proper and safe operation.
113202 - 10
www.amdry.com
23
A 1/8” N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas supply
line immediately upstream of each dryer.
IMPORTANT: Pipe joint compounds that resist the action of natural and liquid propane (L.P.) gases
must be used.
IMPORTANT: Test ALL connections for leaks by brushing on a soapy water solution (liquid
detergent works well).
WARNING: NEVER TEST FOR GAS LEAKS WITH A FLAME!!!
IMPORTANT: The dryer and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).
NOTE: The dryer must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.5 kPa).

H. STEAM INFORMATION
It is your responsibility to have ALL steam plumbing connections made by a qualified professional to 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, regulated air (80 psi +/- 10 psi [5.51 bar +/- 0.69 bar]). Refer
to Steam Damper Air System Connections.
1. Steam Coil pH Level
The normal pH level for copper type steam coils must be maintained between a value of 8.5 to 9.5. For
steel type steam coils the pH level must be maintained between a value of 9.5 to 10.5. These limits are set
to limit the acid attack of the steam coils.
IMPORTANT: Coil failure due to improper pH level will VOID THE WARRANTY.
2. Steam Requirements – High Pressure

3. Installation Instructions
To 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 lines and steam
return lines, or improper steam plumbing, will result in poor performance and can cause component failure.
Clean, dry, regulated steam must be provided to the dryer.
IMPORTANT: Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY.
a. The pressure of the condensate in the steam supply will cause water hammer and subsequent heat
exchanger (steam coil) failure. The steam supply connection into the main supply line must be made
within a minimum 12-inch (30.48 cm) riser. This will prevent any condensate from draining towards the
dryer.
b. The steam supply 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.
113202 - 10
www.amdry.com
25
d. Shutoff valves for each dryer should be installed in the supply, return, and drip trap return lines. This
will allow the dryer to be isolated from the supply and return mains if the dryer needs maintenance work.
e. Install an inverted bucket steam trap and check valve for each unit at least 12-inches (30.48 cm) below
steam coil, as close to the coil as possible; 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.
f. A 3/4-inch (19.05 mm) vacuum breaker should be installed for each unit in the piping. This will prevent
the condensing steam from causing a vacuum inside the coil and possibly damaging the coil.
g. Dryers with optional solenoid valve must be mounted with coil positioned directly above the valve body.
h. The supply and return lines should be insulated. This will save energy and provide safety for the
operator and maintenance personnel.
i. 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.
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 above the electric service relay box.

b. Air Connections
Air connections to system – 1/4” Quick Connection
c. No air regulation or filtration is provided with the dryer. External regulation and filtration of 80 psi (5.51
bar) must be provided. It is suggested that a regulator and 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 illustration below (Diagram 1), allows the coil to stay constantly
charged, eliminating repeated expansion and contraction. When the damper is opened, the air immediately
passes through the already hot coil, providing instant heat to start the drying process. When the damper is
closed, ambient air is drawn directly into the basket (tumbler), allowing a rapid cool down.
Diagram 1 – shows the damper in the heating (open) mode, allowing heat into the basket (tumbler).
Diagram 2 – shows the damper in the cool down (closed) mode, pulling ambient air directly into the basket
(tumbler) without passing through the coils.
NOTE: With the dryer off or with no air supply, the damper is in the cool down mode as shown in the
illustration below (Diagram 2).

6. Steam Damper Air Piston (Air Control) Operation Adjustment
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 page 33 for instructions to
check steam damper system operation. If damper air adjustment is necessary, locate the flow-control valve
and make the necessary adjustments as noted below.
I. WATER INFORMATION
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 fire suppression system is not connected, installed, or
maintained properly.
INSTALLATION
1. Requirements
The fire suppression system 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.
28
American Dryer Corp.
113202 - 10
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 fire suppression 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.
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 photograph).
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
OPTIONAL MANUAL BYPASS
Provisions are made in the dryer’s fire suppression 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 fire suppression system
will be INOPERATIVE!!
30
American Dryer Corp.
113202 - 10
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
fire suppression 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 fire suppression system is
INOPERATIVE!!
J. PREPARATION FOR OPERATION AND 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 case of
208 VAC or 230/240 VAC, the supply voltage must match the electric service exactly.
3. GAS MODELS – check to ensure that the dryer is connected to the type of heat or gas indicated on the
dryer data label.
4. GAS MODELS – the sail switch damper assembly was installed and adjusted at the factory prior to
shipping. However, each sail switch adjustment must be checked to ensure that this important safety
control is functioning.
5. Check to be sure drive belts between idler pulley and motor pulley have been reconnected.
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 ensure that they are closed and secured in place.
9. 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.
10. Rotate the basket (tumbler) by hand to be sure it moves freely.
11. Check bolts, nuts, screws, terminals, and fittings for security.
12. STEAM MODELS – check to ensure air supply (80 psi [5.51 bar]) is on 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.

K. 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: The 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 ensure that the water column (W.C.) pressure is correct and consistent.
NOTE: Water column pressure requirements (measured at the gas valve pressure tap):
Natural Gas --------------------- 3.5 Inches (8.7 mb) Water Column.
Liquid Propane (L.P.) Gas --- 10.5 Inches (26.1 mb) Water Column.
IMPORTANT: There is no regulator provided in an L.P. dryer. The water column (W.C.) pressure
must be regulated at the source, (L.P. tank) or an external regulator must be added
to each dryer.
32
American Dryer Corp.
113202 - 10
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 illustration on page 28 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 76 lb (34.5 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 ensure that no further adjustments are
necessary and that ALL components are functioning properly.
9. Make a complete operational check of ALL operating controls.
a. Microprocessor controller (computer) programs and selections
Each microprocessor controller (computer) has been preprogrammed by the factory with the most
commonly used parameter (program) selections. If computer program changes are required, refer to
the computer programming manual, which was shipped with the dryer.
b. Dual timer dryers check

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 COULD CREATE A 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.
Clean the lint drawer or screen every third or fourth load.
NOTE: Cleaning frequency can best be determined at each location.
SUGGESTED CLEANING SCHEDULE
DAILY (beginning of each work shift)
Clean lint from screen.
Inspect lint screen and replace if torn.
WEEKLY
Clean lint accumulation from lint chamber, thermostat, and microprocessor temperature sensor (sensor bracket)
area.
WARNING: TO AVOID THE HAZARD OF ELECTRICAL SHOCK, DISCONTINUE
ELECTRICAL SUPPLY TO THE DRYER.
STEAM DRYERS
Clean the steam coil fins. We suggest using compressed air and a vacuum cleaner with brush attachment.
WARNING: 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 local air-conditioning supply houses.
113202 - 10
www.amdry.com
39
90 DAYS
Remove lint from around basket (tumbler), drive motors, and surrounding areas.
Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment.
Clean any lint that may have collected in and around the blower motor casing openings.
IMPORTANT: To prevent damage, avoid cleaning or touching ignitor and flame-probe assembly.
Remove lint accumulation from inside the control box and at the rear area behind the control box.
Impellor (fan/blower) shaft bearings should be lubricated using Shell Alvania #2 grease or its equivalent.
Generically, this grease would be described as an NLGI grade 2 multipurpose industrial with a lithium thickener
and mineral base oil.
6 MONTHS
Inspect and remove lint accumulation in customer-furnished exhaust ductwork system and from dryer’s internal
exhaust ducting.
WARNING: THE ACCUMULATION OF LINT IN THE EXHAUST DUCTWORK COULD
CREATE A FIRE HAZARD.
WARNING: DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION
AIR. CHECK CUSTOMER FURNISHED BACK DRAFT DAMPERS IN
EXHAUST DUCTWORK. INSPECT AND REMOVE ANY LINT
ACCUMULATION, WHICH CAN CAUSE DAMPER TO BIND OR STICK.
NOTE: A back draft damper that is sticking partially closed can result in slow drying and shutdown of
the heat circuit safety switches or thermostats.
NOTE: When cleaning the dryer cabinets, 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 switch, lint drawer switch, sail switch, burner,
and hi-limit thermostats).
C. LUBRICATION
The motor bearings, and under normal/most conditions the basket (tumbler) and idler bearings, are permanently
lubricated. It is physically possible to relubricate the basket (tumbler) bearings if you choose to do so even though
this practice may not be necessary. Use Shell Alvania #2 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.

SECTION VIII
PROCEDURE FOR FUNCTIONAL CHECK
OF REPLACEMENT COMPONENTS
1. Phase 7 Microprocessor Controller (Computer) Models
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 microprocessor controller (computer) board are lit.
(Refer to the illustration below.)
42
American Dryer Corp.
113202 - 10
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.

SECTION IX
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.
