IMPORTANTINFORMATION
A. RECEIVINGAND HANDLING
The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover (or optional
box) as a means of preventing damage in transit. Upon delivery, the dryer and/or packaging, and wooden skid should
be visually inspected for shipping damage. If any damage whatsoever is noticed, inspect further before delivering
carrier leaves.
Dryers damaged in shipment:
1. ALL dryers should be inspected upon receipt and before they are signed for.
2. If there is suspected damage or actual damage, the trucker’s receipt should be so noted.
3. If the dryer is damaged beyond repair, it should be refused. Those dryers, which were not damaged in a
damaged shipment should be accepted, but the number received and the number refused must be noted on the
receipt.
4. If you determine that the dryer was damaged after the trucker has left your location, you should call the delivering
carrier’s freight terminal immediately and file a claim. The freight company considers this concealed damage.
This type of freight claim is very difficult to 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 [phone].
IMPORTANT: Thetumbler section ofthe dryermustbe transportedandhandled in anupright positionat
ALLtimes.

A. REASSEMBLYOF DRYER
IMPORTANT: Alwayskeepthetumblersectionofthedryerinanuprightpositionwhenmovingit.
The dryer may be shipped one (1) of two (2) ways; as a complete unit fully assembled and ready for hookup or with the
tumbler section separated from the base. If the dryer is shipped in two (2) pieces, the tumbler section will have to be
lifted onto the base. Use cables through the eyebolts on top of the tumbler section, or use a forklift for the lifting
process.

1. Reassembly Instructions For Gas Dryer Shipped In Two (2) Pieces

12 American Dryer Corporation 113549-8
a. Reassembly Instructions For Non-Tilt Gas Dryers:
Lift the tumbler section onto the base.
1) The dryer has four (4) support posts assemblies, which are located in each corner of the base. On top of
each post assembly is a clevis block, which must be bolted to the tumbler section. Use the
4-1/2” diameter x 1-1/8” long bolts and lock washers to bolt each clevis block to the tumbler section.
(Refer to View 1 on the previous page.)
2) Tumbler power cable reconnection:
a) A plug and cable is located in the right of the base. This must be lifted up and reconnected into the
mating socket located at the bottom of the right tumbler section.
b) Pull the tumbler section power cable up from the left side of the base through the hole in the bottom of
the tumbler section. Reconnect the wires of this cable into the 2-inch x 4-inch (5.08 cm x 10.16 cm)
tumbler junction box located at the bottom of the tumbler section. (Refer to the illustration on the
previous page.)
c) Drop the controlcable connector from the rear right side of the tumbler section intothebase. Reconnect
the industrial grade plug in to its mating socket.
3) Bolt the 20-inch (50.8 cm) diameter exhaust duct transition piece to the dryers rectangular exhaust duct.
The exhaust duct exits the dryer from the rear of the base. (Refer to the illustration on the previous
page.) Use the 1/4-20 self-drilling screws supplied with the dryer.

page.) Use the 1/4-20 self-drilling screws supplied with the dryer.
4) If a steam dryer is shipped in two (2) pieces, the steam coil may have been removed from the top of the
tumbler section and shipped with the base. If this is the case, lift the steam coil on to the top of the tumbler
section with the steam pipe connections facing towards the right side of the dryer and bolt the coil to the
top of the dryer with a 1/4-inch hardware supplied. There are three (3) panels that cover the front, right
side, and rear of the steam coil. Fasten these in position also.

113549 - 8 www.adclaundry.com 15
B. LOCATION REQUIREMENTS
Before installing the dryer, ensure the location conforms to local codes and ordinances. In the absence of such codes
or ordinances the location must conform with National Fuel Gas Code ANSI Z223.1/NFPA 54, or in Canada, the
installation must conform to applicable Canadian Standards: Natural Gas and Propane Installation Code CSA B149.1.
The non-tilting model 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 service. Aminimum of 12-inches (30.48 cm) must be allowed between the top of
a gas dryer and the ceiling. Aceiling height of 120-inches (304.8 cm) is required for gas dryers, and a ceiling height for
130-inches (330.2 cm) is required for steam dryers. The dryer must be leveled for proper operation. If shimming is
required, put metal shims, which are the same size as the base feet under the base feet. The dryer must be lagged to
the floor.
WARNING: Dryer shouldbe locatedwherea minimum lengthofexhaustductwill benecessary.
1. The dryer must be installed with a proper exhaust duct connection to the outside.
2. The dryer must be installed with provisions for adequate combustion and make-up air supply.
3. Clearance provisions must be made from combustible construction.
4. Provisions must be made for adequate clearances for servicing and for operation.
5. The dryer must be installed with adequate clearance for air openings into the combustion chamber.
CAUTION: Thisdryer produces combustiblelintand mustbeexhausted totheoutdoors. Every 6 months,
inspectthe exhaust ducting andremoveanylintbuildup.
IMPORTANT: Dryermust beinstalledinalocation/environment, whichthe ambienttemperature
remainsbetween 40° F(4.44° C)and130° F(54.44° C).

16 American Dryer Corporation 113549-8
C. FRESH AIR SUPPLYREQUIREMENTS
This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the
nationalinstallation regulations.
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 mustbe 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 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 (184 cmm) for each steam dryer. As a
general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 6 square feet (0.56 square
meters) is required for each gas dryer and a minimum of 8 square feet (0.74 square meters) for each 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.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes
or predominantly low pressure areas.
IMPORTANT: Make-upair mustbeprovided froma source freeof dry cleaningsolvent fumes. Make-up
airthat is contaminated by drycleaningsolventfumeswillresultinirreparabledamagetothe
motorsandother dryercomponents.
NOTE: Componentfailure due to dry cleaningsolventfumeswillVOIDTHEWARRANTY.
