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 packaging, and wooden
skid should be visually inspected for shipping damage. If any damage whatsoever is noticed, inspect further
before delivering carrier leaves.
Dryers damaged in shipment:
1. ALL dryers should be inspected upon receipt and before they are signed for.
2. If there is suspected damage or actual damage, the trucker’s receipt should be so noted.
3. If the dryer is damaged beyond repair, it should be refused. Those dryers which were not damaged in a
damaged shipment should be accepted, but the number received and the number refused must be noted
on the receipt.
4. If you determine that the dryer was damaged after the trucker has left your location, you should call the
delivering carrier’s freight terminal immediately and file a claim. The freight company considers this concealed
damage. This type of freight claim is very difficult to get paid and becomes extremely difficult when more
than a day or two passes after the freight was delivered. It is your responsibility to file freight claims.
Dryer/parts damaged in transit cannot be claimed under warranty.
5. Freight claims are the responsibility of the consignee, and ALL claims must be filed at the receiving end.
ADC assumes no responsibility for freight claims or damages.
6. If you need assistance in handling the situation, please contact the ADC Traffic Manager at +1 (508) 6789000.
IMPORTANT: The dryer must be transported and handled in an upright position at all times.

SECTION III
INSTALLATION PROCEDURES
Installation should be performed by competent technicians in accordance with local and national regulations or
codes of the country of destination.
IMPORTANT: If connection to this appliance is made with flexible hose it must be suitable for
the appliance category in accordance with national installation regulations of the
country of destination, and if in doubt the installer must contact the supplier. The
manufacturer of this appliance DOES NOT recommend the use of flexible gas
supply line/hose.
A. UNPACKING/SETTING UP
Remove protective shipping material (i.e., plastic wrap and optional shipping box) from dryer.
IMPORTANT: Dryer must be transported and handled in an upright position at all times.
NOTE: For OPL dryer models equipped with locks, the lock used is a dummy lock and no key is
supplied or needed. The lock can be turned with any key, a screwdriver, a small coin, or any
small sharp object. For coin-operated dryers, the MK-100 (master key for both the Control
Door and Lint Door) should be made accessible because it will be needed throughout various
phases in the installation of the dryer.
The dryer can be moved to its final location while still attached to the skid or with the skid removed. To un-skid
the dryer, locate and remove the four (4) bolts securing the base of the dryer to the wooden skid. Two (2) are at
the rear base (remove the back panel for access), and two (2) are located in the bottom of the lint chamber. To
remove the two (2) bolts located in the lint chamber area, remove the lint door.
With the skid removed, to make it easier to slide the dryer into its final position, slightly lower ALL four (4)
leveling legs, so that the dryer will slide on the legs instead of the base frame.
To increase bearing life and improve efficiency, the dryer should be tilted slightly to the rear.
1. Leveling Dryer
The dryer is equipped with four (4) leveling legs, one at each corner of the base. Two (2) are located at the
rear of the dryer base, and two (2) are located in the lint chamber (coop). To increase bearing life and
improve efficiency, the dryer should be tilted slightly to the rear.
8
B. LOCATION REQUIREMENTS
Before installing the dryer, be sure the location conforms to local and national codes and ordinances.
1. The dryer must be installed on a sound level floor capable of supporting its weight. It is recommended that
carpeting be removed from the floor area that the dryer is to rest on.
2. The dryer must not be installed or stored in an area where it will be exposed to water and/or weather.
3. The dryer is for use in noncombustible locations.
4. Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply in
Section D).
5. Clearance provisions must be made from combustible construction as noted in this manual (refer to Dryer
Enclosure Requirements in Section C).
6. Provisions must be made for adequate clearances for servicing and for operation as noted in this manual
(refer to Dryer Enclosure Requirements in Section C).
7. Dryer must be exhausted to the outdoors (refer to Exhaust Requirements in Section E).
8. Dryer must be located in an area where correct exhaust venting can be achieved as noted in the manual
(refer to Exhaust Requirements in Section E).
IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary.
9
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of
twelve (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: Allowance must be made for opening the control door.
Dryers may be positioned side wall to side wall. However, a 1/16” (0.16 cm) minimum allowance must be made
for the opening and closing of the control doors. 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.
10
D. FRESH AIR SUPPLY
The EURO-35 air supply (make-up air) must be given careful consideration to assure proper performance of
each dryer. An unrestricted source of air is necessary for each dryer. As a general rule, an unrestricted air
entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (.14 square meters) is required for
each dryer. If registers or louvers are installed over the openings, then the area must be increased. It is not
necessary to have a 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 the dryers.
EXAMPLE: For a bank of eight (8) dryers, two (2) unrestricted openings measuring 2 feet by 3 feet - .61
meters by .91 meters - (6 square feet [.56 square meters] is acceptable).
IMPORTANT: Make-up air openings should not be located in an area directly near where exhaust
vents exit the building.
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 motors and other dryer components.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
11
E. EXHAUST REQUIREMENTS
Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work will
create excessive back pressure which results in slow drying, increased use of energy, and shutdown of the burner
by the airflow (sail) switch, burner hi-limit, or lint chamber hi-heat protector thermostat.
Wherever possible, it is suggested that a separate (single) exhaust duct be provided for each dryer.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCT WORK CAN
CREATE A POTENTIAL FIRE HAZARD.
CAUTION: DRYER MUST BE EXHAUSTED TO THE OUTDOORS.
The exhaust duct work should be laid out in such a way that the duct work travels as directly as possible to the
outdoors with as few turns as possible. The shape of the duct work is not critical so long as the minimum cross
section area is provided. Single or independent dryer venting is recommended.
It is suggested that the use of 90° turns be avoided; use 30° or 45° angles instead.
The duct work 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
duct work 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 duct work for periodic inspection and
cleaning.
IMPORTANT: When connecting duct work to the dryer exhaust duct, be sure that when screws are
used they DO NOT restrict the operation (both opening and closing) of the damper.
NOTE: When the exhaust duct passes through a wall, ceiling, or roof made of combustible materials,
the opening must be 2-inches (5 cm) larger (all the way around) than the duct. The duct must
be centered within this opening.
To protect the outside end of horizontal duct work from the weather, a 90° elbow bent downward should be
installed where the exhaust exits the building. If the duct work 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: DO NOT use screens or caps on the outside of opening of exhaust duct work.
IMPORTANT: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must
not exceed 0.3 inches of water column (0.75 mbar).
12
SINGLE DRYER VENTING
IMPORTANT: For exhaust duct runs up to 20 feet (6 meters), a minimum size of 10-inches (25 cm)
must be used.
HORIZONTAL VENTING
When a single 10-inch (25 cm) horizontal vent is used, the duct work to the outlet cannot exceed 20 feet (6 m)
(refer to Illus. A below). This calculation of 20 feet (6 m) compensates or allows for the use of a maximum of
only one (1) elbow (which is the outside outlet protection).
Illus. A
13
VERTICAL VENTING
When vertical single 12-inch (30.48 cm) venting is used (refer to Illus. B below), the duct work from the dryer
to the outside outlet cannot exceed 25 feet (7.6 meters) (refer to Illus. B below). This calculation compensates
for the use of a maximum of three (3) elbows including the two (2) elbows creating the 180° (turned downward)
outside outlet.
Illus. B
If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross section
area of the duct work must be increased in proportion to the number of elbows or duct run added.
IMPORTANT: Minimum duct size for a dryer that is vented horizontally is 10-inches (25.4 cm) for a
round duct (or different cross section with an area of 80 square inches [516.12 square
centimeters]).
IMPORTANT: Minimum duct size for a dryer that is vented vertically is 12-inches (30.48 cm) for a
round duct (or different cross section with an area of 115 square inches [741.93
square centimeters]).
IMPORTANT: Never reduce the duct size anywhere downstream of the dryer.
IMPORTANT: For extended duct work runs, the cross section area of the duct can only be increased
to an extent. For extended duct work runs, a professional HVAC firm should be
consulted for proper venting information.
14
MULTIPLE DRYER (Common) VENTING
If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled
into a common main duct. Each dryer is provided with a back draft damper. The individual ducts should enter the
bottom or side of the main duct at an angle not more than 45° in the direction of the airflow.
The main common duct may be any shape so long as the minimum cross-sectional area is provided. The main
duct should be tapered with the diameter increasing before each individual 10-inch (25 cm) duct is added (refer
to Illus. C for Horizontal Venting and Illus D for Vertical Venting).
IMPORTANT: No more than four (4) dryers maximum should be connected to one (1) main
common duct with a vertical run.
NOTE: Distance between dryer single ducts being connected to the main common duct must be a
minimum of 38-1/4” - 97.15 cm - (dryer width).
Duct work should be laid out in such a manner where allowances are made at rear area of the
dryer for removal of rear service panels or guards.
The illustrations on page 16 show the minimum cross-section area for multiple dryer venting. These figures
must be increased in proportion if the main duct run from the last dryer to where it exhausts has numerous
elbows or is unusually long.
IMPORTANT: For extended duct work runs, the cross-section area of the duct can only be increased
to an extent. For extended duct work runs, a professional HVAC firm should be
consulted for proper venting information.
Refer to page 16 for Multiple Dryer Horizontal Venting and Vertical Venting examples/illustrations.
15
16
IMPORTANT VENTING REMINDERS
1. Ductwork sizeandinstallationshould be done by a qualified professional.
2. The dryer must be exhausted to the outdoors.
3. Duct work should be routed as short as possible to the outdoors with as few elbows as possible.
4. Avoid 90° turns, use 30° or 45° turns instead.
5. Thesizeoftheductwork must be a minimum of 10-inches (25.4 cm) for horizontal runs and 12-inches
(30.48 cm) for vertical runs (refer to previous page [page 16]).
6. The inside of the duct work should be as smooth as possible with no projections from sheet metal screws.
7. Ducts added should overlap the duct to which it is to be connected.
8. ALL ducts should be taped to prevent moisture and lint from escaping into the building.
9. Inspection or clean out doors should be installed throughout strategic points in the duct work for periodic
inspection and cleaning.
10. Wherever the duct passes through combustible materials, the opening must be 2 inches (5.08 cm) larger (all
the way around) than the duct. The duct must be centered within this opening.
11. The outside of the duct work must be protected from the weather. A 90° elbow must be used for horizontal
run and when vertically through a roof by using a 180° turn to point the opening downward. The distance
between the exhaust duct and the nearest obstruction (i.e., roof or ground) must be twice the diameter of the

G. GAS INFORMATION
It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the gas
plumbing installation is adequate and conforms with local and national regulations or codes of the country of
destination.
IMPORTANT: FAILURE TO COMPLY WITH CODES or ORDINANCES, and/or
REQUIREMENTS IN THIS MANUAL, CAN RESULT IN PERSONAL
INJURY and IMPROPER OPERATION OF THE DRYER.
The dryer and its individual shut-off valves 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). The dryer must be isolated from
the gas supply piping system by closing its individual manual shut-off valve during any pressure test of the gas
supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).
IMPORTANT: Failure to isolate or disconnect the dryer from supply as noted can cause irreparable
damage to the gas valve which will VOID THE WARRANTY.
WARNING: FIRE or EXPLOSION COULD RESULT.
1. Gas Supply
The gas dryer installation must meet local codes and ordinances and must be done by a qualified professional.
NOTE: Undersized gas piping will result in ignition problems, slow drying, increased use of energy, and
can create a safety hazard.
The dryer must be connected to the type of heat/gas indicated on the dryer label affixed behind the right
control box door. If this information does not agree with the type of gas available, DO NOT operate the
dryer. Contact the distributor who sold the dryer or the ADC factory.
IMPORTANT: Any burner changes or conversions must be made by a qualified professional.
The input ratings shown on the dryer data label are for elevations up to 2,000 feet (610 meters), unless
elevation requirements of over 2,000 feet (610 meters) were specified at the time the dryer order was
placed with the factory. The adjustment or conversion of dryers in the field for elevations over 2,000 feet

3. Piping Connections
ALL components/materials must conform to any National Gas Code specifications. 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’s being supplied.
The dryer is provided with a 3/4” N.P.T. inlet pipe connection extending out the back area of the burner box.
The minimum pipe size (supply line) to the dryer is 3/4” N.P.T. For ease in servicing, the gas supply line of
each dryer must have its own shut-off 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. (liquid propane) 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.
28
Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-inch pipe gas
loop be installed in the supply line serving 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 of water column (30 mbar)
pressure. Refer to the illustrations on the previous page (page 28).
NOTE: A water column test pressure of 3.5 inches (8.7 mbar) for natural gas and 10.5 inches (26.2
mbar) for L.P. (liquid propane) 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 any National Gas Code specifications. 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’s being supplied.
IMPORTANT: The dryer and its individual shut-off 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
shut-off valve during any pressure test of the gas supply system at test pressures equal to or less
than 1/2 psig (3.5 kPa).
29
H. STEAM INFORMATION
It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the
steam plumbing installation is adequate and conforms with local and national regulations or codes.
Care must be exercised when leveling steam dryers into final position. After leveling the dryer, check the
downward pitch of the heat exchanger from front to rear with a level. Likewise, check the downward pitch of
the return condensate manifold toward its outlet part. Absence of these downward pitches will result in
probable water hammer and premature heat exchanger fracture and leakage.
The presence of condensate in the steam will cause water hammer and subsequent heat exchanger failure. The
steam supply connection must be taken from the top of a well-dripped steam main. If the supply run-out to the
dryer exceeds 20 feet (6 meters), it should be dripped just before the control valve with a proper trap and dirt
pocket.
IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in
component failure which will VOID THE WARRANTY.
NOTE: The EURO-35 is manufactured with a pneumatic (piston) damper system which requires an
external supply of air 80 PSI +/- 10 PSI (5.5 bar +/- 0.7 bar).
1. Steam Coil PH Level
The normal PH level for copper type steam coils must be maintained between a value of 8.5 to 9.5. For
steel type steam coils the PH level must be maintained between a value of 9.5 to 10.5. These limits are set
to limit the acid attack of the steam coils.
IMPORTANT: Coil failure due to improper PH level will VOID THE WARRANTY.

3. Installation Instructions
To insure an adequate supply of steam is provided, be sure that the steam lines and steam return lines are
sized and laid out as stipulated in this manual. Inadequate steam lines and steam return lines or improper
steam plumbing will result in poor performance and can cause component failure. Clean, dry steam must
be provided to the dryer.
IMPORTANT: Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY.
30
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 with a minimum 10-inch (25 cm) riser. This will prevent any condensate from draining towards the
dryer.
b. The steam supply piping to the dryer must include a 12-inch (30 cm) rise along with a drip trap and check
valve. This will prevent any condensate from entering the steam coil.
c. Flexible hoses or couplings must be used. The dryer vibrates slightly when it runs and this will cause the
steam coil connections to crack if they are hard piped to the supply and return mains.
d. Shut-off valves for each dryer should be installed in the supply line, return line, and drip trap return line.
This will allow the dryer to be isolated from the supply main and the return main if the dryer needs
maintenance work.
e. Install an inverted bucket steam trap and check valve at least 12-inches (30 centimeters) below the
steam coil as close to the coil as possible.
1) A trap with capacity of 700 pounds (320 Kg) of condensate per hour at 125 psi (862 kPa) is needed
for each unit.
f. The supply line and the return line should be insulated. This will save energy and provide for the safety
of the operator and maintenance personnel.
g. Water pockets in the supply line, caused by low points, will provide wet steam to the coil possibly causing
steam coil damage. ALL horizontal runs of steam supply piping should be pitched 1/4-inch for every
one (1) foot (0.64 cm/30.5 cm) back towards the steam supply header causing the condensate in the line
to drain to the header. Install a bypass trap in any low point to eliminate wet steam.
IMPORTANT: Flexible hose/coupling must be used. Coil failure due to hard plumbing connections
will VOID THE WARRANTY.
31
4. Steam Damper Air System Connections
The EURO-35 is manufactured with a pneumatic (piston) damper system which requires an external supply
of compressed air. The air connection is made to the steam damper solenoid valve which is located at the
rear inner top area of the dryer just in front of the electric service relay box.

c. Air Regulation
No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 psi (552 kPa)
must be provided. It is suggested that a regulator/filter gauge arrangement be added to the compressed
air line just before the dryer connection. This is necessary to insure that correct and clean air pressure
is achieved.
32
5. Steam Damper System Operation
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 (Diagram 1), 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 2).
Diagram 1 shows the damper in the heating (open) mode, allowing heat into the basket (tumbler).
Diagram 2 shows the damper in the cool down (closed) mode, pulling ambient air directly into the basket
(tumbler) without passing through the coils.
NOTE: With the dryer off or with no air supply, the steam damper is in cool down mode as shown in
Diagram 2.
33
a. Steam Damper Air Piston (Flow Control) Operation Adjustment
Damper operation was tested and adjusted prior to shipping at 80 psi (552 kPa). If damper air adjustment
is necessary, locate the flow control valve and make the necessary adjustments as noted below.
34
I. PREPARATION FOR OPERATION/START-UP
The following items should be checked before attempting to operate the dryer:
1. Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.
2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label affixed to
the back side of the top front control/service door. In the case of 208 VAC or 230/240 VAC, the supply
voltage must match the electric service specifications of the data label exactly.
3. GAS MODELS - check to assure that the dryer is connected to the type of heat/gas indicated on the
dryer data label.
4. GAS and ELECTRIC MODELS - the sail switch damper assembly was installed and adjusted at the
factory prior to shipping. However, each sail switch adjustment
must be checked to assure that this important safety control is
functioning.
5. Check bolts, nuts, screws, terminals, and fittings for tightness and security.
6. GAS MODELS - be sure that ALL gas shut-off valves are in the open position.
7. Check ALL back guard panels and service box covers have been replaced.
8. Check the lint drawer to assure that it is closed and secured in place.
9. Rotate the basket (tumbler/drum) by hand to be sure it moves freely.
10. STEAM MODELS - check to insure that a clean, dry, regulated air supply 80 psi (552 kPa) is connected
to the dryer (air operated DAMPER SYSTEM ONLY).
11. STEAM MODELS - check to insure ALL steam shut-off valves are open.
12. STEAM MODELS - check steam damper operation.
13. Check tumbler bearing set screws to insure that they are ALL tight.
14. Check vent is connected to the machine and is exhausted to the outdoors.
15. There should be a source of fresh air entering the room. This source should not be near where the
dryer(s) exhaust to the outside.
35
J. PREOPERATIONAL TESTS
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test
should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or
due to marginal location (installation) conditions.
1. Turn on electric power to the dryer.
2. Refer to the Operating Instructions for starting your particular model dryer.
3. GAS MODELS ONLY
a. When a gas dryer is first started (during initial start-up), it has a tendency not to ignite on the first ignition
attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for the air
to be purged from the lines.
NOTE: During the purging period, check to be sure that ALL gas shut-off valves are open.
NOTE: Gas model dryers are equipped with a Hot Surface Ignition (HSI) system which has internal
diagnostics. If ignition is not established after one (1) time, the heat circuit in the HSI module
will attempt two more ignitions (total of three ignition attempts). If there is no flame after the
third ignition attempt the HSI module will lock out until it is manually reset. To reset the HSI
(Hot Surface Ignition) system, open and close the main door and restart the dryer.
b. A gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water
column (W.C.) pressure is correct and consistent.
NOTE: Water column (W.C.) pressure requirements (measured at the pressure tap of the gas valve
body):
Natural Gas -------------------- 3.5 Inches Water Column (8.7 mbar)
Liquid Propane (L.P.) Gas ----- 10.5 Inches Water Column (26.2 mbar)
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.
4. Make a complete operational check of ALL safety related circuits:
a. Door switch(es)
b. Hi-Limit thermostats
c. Cycling thermostat
d. GAS and ELECTRIC MODELS ONLY - Sail Switch
NOTE: The sail switch can be checked for proper operation by opening the lint drawer. While pushing
the lint drawer switch in, start a drying cycle. The heating unit should not activate (wait 30
seconds). If heat does activate, make necessary adjustments to the sail switch.
36
5. Make a complete operational check of ALL operating controls.
NOTE: If computer program changes are required, refer to the computer programming section of the
manual supplied with the dryer.
6. The dryer should be operated through one (1) complete cycle to assure that no further adjustments are
necessary and that ALL components are functioning properly.
IMPORTANT: The dryer basket (tumbler) is treated with a protective coating. ADC suggests
tumbling old clothes or material in the basket (tumbler), using a mild detergent to
remove the protective coating.
7. 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 (impellor/fan) wheel 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, 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.
K. PREOPERATIONAL INSTRUCTIONS
COIN MODELS
1. Automatic Mode (Microprocessor [Computer] Models)
a. When turning on power or when no cycle is in progress, the L.E.D. (light emitting diode) display will read
“FILL” and/or “Amount to Start.”
b. Insert coin(s).
Once correct “Amount to Start” has been inserted the L.E.D. (light emitting diode) display will read
“PUSH.”
c. Select temperature by pushing “HI TEMP,” “LO TEMP,” or “PERM PRESS.” The dryer will start, the
L.E.D. (light emitting diode) display will read the temperature cycle selected, and the drying time portion
of the L.E.D. (light emitting diode) display will read “00” and count upward as time elapses.

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 duct work 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.
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 in a drawer below the main door. Open the lint drawer, brush or vacuum the lint
off the lint screen, and remove the lint. Inspect lint screen and replace if torn.
NOTE: The frequency of cleaning the lint screen can best be determined from experience at each
location.
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 HVAC supply houses.
44
90 DAYS
Inspect and remove lint accumulation in customer-furnished exhaust duct work system and from dryer’s
internal exhaust ducting.
WARNING: THE ACCUMULATION OF LINT IN THE EXHAUST DUCT WORK CAN
CREATE A POTENTIAL FIRE HAZARD.
WARNING: DO NOT OBSTRUCT THE FLOW OF COMBUSTION and VENTILATION AIR.
WARNING: INSPECT and REMOVE ANY LINT ACCUMULATION WHICH CAN CAUSE
THE BACK DRAFT 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 set screws), non-permanent gas connections (unions, shut-off valves,
orifices, and grounding connections). Motor and drive belts should be examined. Cracked or seriously
frayed belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of
controls and valves. Complete operational check of ALL safety devices (door switches, lint drawer switch,
sail switch, burner, and hi-limit thermostats).
C. LUBRICATION
The motor bearings, idler bearings...and under normal/most conditions the tumbler bearings are permanently
lubricated. It is physically possible to re-lubricate the tumbler bearings if you choose to do so even though this
practice is not necessary. Use Shell Alvania #3 or its equivalent. The 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 Part No. 882159, which includes two (2) fittings.
45
D. LINT DRAWER REMOVAL
To remove the lint drawer from the dryer pull drawer out approximately halfway. Rotate/move lint drawer stop
hinge (refer to the illustration below) downward and pull drawer out.
IMPORTANT: After replacing the lint drawer back into the dryer, be sure to rotate/move hinge back
to the upward stop position.
