IMPORTANT INFORMATION
A. RECEIVING and HANDLING
The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover
(or optional box) as a means of preventing damage in transit. Upon delivery, the dryer and/or packaging, and
wooden skid should be visually inspected for shipping damage. f 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. f there is suspected damage or actual damage, the trucker's receipt should be so noted.
3. f 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. f 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. t 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. f you need assistance in handling the situation, please contact the ADC Traffic Manager at
[phone].
IMPORTANT: The tumbler section of the dryer must be transported and handled in an upri ht
position at ALL times.

(for Electrical Connections).
A. REASSEMBLY OF DRYER
IMPORTANT: Always keep the tumbler (basket) section of the dryer in an upri ht position when
movin it.
The ML-200 (gas model dryer) may be shipped
one of two ways; as a complete unit fully as-
sembled and ready for hookup or in two (2)
pieces with the middle frame separated from
the base. At installation, the middle frame will
be lifted onto the base. Use cables through
the eye bolts on top of the middle frame for
lifting. Fasten the middle frame to the base by
using the four (4) #3/8-16 bolts provided with
the unit. Also, reconnect the V-belts, belt guard
at the rear end of the unit, and reconnect the
electrical plugs located in the front control
boxes.
The ML-200 (steam models) can also be
shipped with the middle frame separated from
the base. n this case, follow the instructions
for reassembly of the gas dryer. The steam
dryer may also be shipped with the steam coil
and damper piston removed. f this is the case,
lift the steam coil on top of the middle frame,
with the steam connection pipes facing the right
side of the unit, and bolt the coil to the top of
the middle frame using the #3/8-16 bolts pro-
vided. Also, bolt the damper piston and sole-
noid valve to the top of the middle frame using
the bolts provided. There are three (3) panels
that cover the front, right side, and rear of the
steam coil. Fasten these in position.

1. Reconnect the four (4) pin/socket connectors at the bottom of the right control box.
2. Reconnect the three (3) pin/socket connectors at the bottom of the left control box.
3. Reconnect the two (2) pin/socket connectors within the left control box.
4. Rewire the drive motor by inserting the three (3) black wires into the T1, T2, and T3 connections of the
Telemecanique drive contactor.
5. Rewire the blower (impellor/fan) motor by inserting the three (3) blue wires into the T1, T2, and T3
connections of the Telemecanique blower contactor.

B. LOCATION REQUIREMENTS
The model ML-200 dryer requires 18-inches (45.72 cm) of space on each side of the dryer and 24-inches (60.96
cm) of space behind the unit for ease of maintenance. A minimum of 12-inches (30.48 cm) must be allowed
between the top of a gas dryer and the ceiling. A ceiling height of 120-inches (304.8 cm) is required for gas
dryers, and a ceiling height of 130-inches (330.2 cm) is required for a steam dryers. The dryer must be leveled
for proper operation. f shimming is required, put metal shims which are the same size as the base feet. The
dryer must be lagged to the floor.
Before installing the dryer, be sure the location conforms to local codes and ordinances.
1. The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be
removed from the floor area that the dryer is to rest on.
IMPORTANT: "The dryer must be installed on non-combustible floors only."
IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary.

13
C. FRESH AIR SUPPLY
When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler (basket), and
exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. f the
make-up air is inadequate, drying time and drying efficiency will be adversely affected. gnition 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 assure proper performance of each dryer. An
unrestricted source of air is necessary for each dryer. An airflow of 5,300 cfm (cubic feet per minute) - 150 cmm
(cubic meters per minute) - must be supplied to each gas dryer and 6,500 cfm (cubic feet per minute) - 184 cmm
- must be supplied to each steam dryer. As a general rule, an unrestricted air entrance from the outdoors
(atmosphere) of a minimum of 5 square feet (0.46 square meters) for each gas dryer and a minimum of 6 square
feet (0.56 square meters) is required for a 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.
t is not necessary to have separate make-up air openings for each dryer. Common make-up air is distributed
equally to ALL dryers. However, they must be set up in such a manner that the make-up air is distributed
equally to ALL the dryers.
IMPORTANT: Make-up air openin s should not be located near duct work exhaust outlets.
If the make-up air openin s is too close to the exhaust outlet, lint and fumes may be
drawn into the dryer area throu h these openin s.
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 cleanin fumes. Make-
up air that is contaminated by dry cleanin solvent fumes will result in irreparable
dama e to motors and other components.
NOTE: Component failure due to dry cleanin solvent fumes will VOID THE WARRANTY.

14
D. EXHAUST REQUIREMENTS
1. General Exhaust Duct Work nformation
Exhaust duct work should be designed and installed by a qualified professional. mproperly sized duct
work will create excessive back pressure which results in slow drying, increased use of energy, over
heating of the dryer, and shut down of the burner by the airflow (sail) switches, burner hi-limits, or tumbler
(basket) hi-heat thermostats.
CAUTION: DRYER MUST BE EXHAUSTED TO THE OUTDOORS.
CAUTION: IMPROPERLY SIZED or INSTALLED EXHAUST DUCT WORK CAN
CREATE A POTENTIAL FIRE HAZARD.
NOTE: When a dryer is exhausted separately, it is recomme ded that a back draft damper be
installed.
NOTE: THE ML-200 MUST BE INDEPENDENTLY EXHAUSTED. COMMON DUCT
WORK IS NOT ACCEPTABLE.
The 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. Single or independent dryer venting is recommended.
The internal dimensions of the dryer's rectangular exhaust vent duct work is 8-inches by 20-inches (20.32
cm by 50.8 cm). The plant's exhaust duct must be at least 20-inches (50.8 cm) in diameter or for a
rectangular duct have a cross-sectional area of 315 square inches (2,032 square centimeters). The duct
work from the dryer to the outside exhaust outlet should not exceed 30 feet (9.14 meters). The shape
of the duct work is not critical so long as the minimum cross-sectional area is provided. t is suggested that
the use of 90º turns in ducting be avoided; use 45º angles instead. The radius of the elbows should
preferably be 1-1/2 times the width or diameter of the duct. Excluding basket/dryer elbow connections or
elbows used for outside protection from the weather, no more than two (2) elbows are used, the cross
section area of the duct work must be increased.
ALL 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 clean-out of lint from the duct work.
IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct should not
exceed 0.3 inches of water column (0.74 mb).
NOTE: Where the exhaust duct work passes throu h a wall, ceilin , or roof made of combustible
materials, the openin must be 2-inches (5.08 cm) lar er (all the way around) than the duct.
The duct must be centered within this openin .

15
a. Outside Duct Work Protection
1) To protect the outside end of horizontal duct work from the weather, a 90º elbow bent downward
should be installed where the exhaust exits the building. f the duct work travels vertically up
through the roof, it should be protected from the weather by using a 180º turn to point the opening
downward. n either case allow at least twice the diameter of the duct between the duct opening
and the nearest obstruction.
IMPORTANT: DO NOT use screens or caps on the outside of openin of exhaust duct work.

16
E. COMPRESSED AIR SUPPLY SYSTEM
A clean, dry, regulated air supply of 80 PS (5.51 bars) compressed air must be supplied to the dryer. The
connection size is 1/8-inch N.P.T. No air filtering or pressure regulating devices are provided with the standard
ML-200 Non-Tilt dryer.
1. Gas Dryers
The air line supply connection is made into the 1/8-inch N.P.T. port on the air jet solenoid valve which is
located in the base of the dryer. (Refer to the illustration below.)
2. Steam Dryers
The air line supply connection is made into the 1/8-inch N.P.T. tee which is located at the left hand side
of the top of the dryer. (Refer to the illustration below.)
