similarly textured rubber materials. Drying in a heated basket (tumbler) may damage
plastics or rubber and may be a fire hazard.
2 American Dryer Corp. 113231-4
7. A program should be established for the inspection and cleaning of lint in the heating unit area, exhaust
ductwork, and inside the dryer. The frequency of inspection and cleaning can best be determined from
experience at each location.
WARNING: The collection of lint in the burner area and exhaust ductwork can create a potential fire
hazard.

SECTION III
INST ALLA TION PROCEDURES
Installation should be performed by competent technicians in accordance with local and state codes. In the
absence of these codes, the installation must conform to applicable American National Standards: ANSI Z223.1LATEST EDITION (National Fuel Gas Code) or ANSI/NFPA NO. 70-LATEST EDITION (National Electrical
Code) or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91
(Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General
Installation and Gas Plumbing) or Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION
(for Electrical Connections).
A. LOCATION REQUIREMENTS
Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such
codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST
EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1M91 (Natural Gas) or CAN/CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION (for General Installation and
Gas Plumbing).
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 noncombustible floors only.”
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
Requirements in
5. Clearance provisions must be made from combustible construction as noted in this manual (refer to Dryer
Enclosure Requirements in
6. Provisions must be made for adequate clearances for servicing and for operation as noted in this manual
(refer to Dryer Enclosure Requirements in
7. The dryer must be installed with a proper exhaust duct to the outside as noted in this manual (refer to
Exhaust Requirements in
8. Dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual
(refer to Exhaust Requirements in
Section D).
Section C).
Section C).
Section E).
Section E).
IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary .
9. The dryer must be installed with adequate clearance for air openings into the combustion chamber.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every
6 months, inspect the exhaust ducting and remove any lint buildup.
8 American Dryer Corp. 113231-4
IMPORTANT: Dryer must be installed in a location/environment, which the ambient
temperature remains between 40° F (4.44° C) and 130° F (54.44° C).
B. UNPACKING/SETTING UP
Remove protective shipping material (i.e., plastic wrap and/or optional shipping box) from dryer.
IMPORT ANT : Dryer must be transported and handled in an upright position at ALL times.
The dryer can be moved to its final location while still attached to the skid or with the skid removed. T o unskid
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
(remove the lint drawer for access).
With the skid removed, to make it easier to slide the dryer into its final position, slightly lower
leveling legs, so that the dryer will slide on the legs instead of the base frame.
ALL four (4)
Leveling Dryer
The dryer is equipped with four (4) leveling legs, one (1) 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.
113231-4 www.amdry.com 9
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible material.
NOTE: Allowances must be made for opening the control door .
A 30-inches (76.2 cm) for optimum opening of load door.
B The maximum thickness of the bulkhead is 4-inches (10.16 cm). For electric dryers the maximum thickness
of the bulkhead is 1-inch (2.54 cm) within 3-inches (7.62 cm) from the top of the control door.
C For gas and electric dryers a minimum overhead clearance of 12-inches (30.48 cm) is required, providing no
sprinkler is located above the dryer. For steam dryers or if a sprinkler is located above the dryer, 18-inches
(45.72 cm) is required.
D Dryer should be positioned 12-inches (30.48 cm) away from the nearest obstruction and 24-inches (60.96
cm) is recommended for ease of installation, maintenance, and service.
E 2-inch (5.08 cm) minimum is required for opening the control door.
F Flooring should be level or below dryer cabinet for ease of removing panels during maintenance.
G Dryers may be positioned sidewall to sidewall, however a 1/16” (1.5875 mm) minimum allowance must be
made for the opening and closing of the control door, along with the removal of panels during maintenance.
10 American Dryer Corp. 113231-4
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
sail switch “fluttering” problems may result, as well as premature motor failure from overheating. The dryer
must be installed with provisions for adequate combustion and make-up air supply .
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer . An
airflow of 900 cfm (25.44 cmm) must be supplied to gas dryers and 1,200 cfm (33.98 cmm) for electric or steam
dryers. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2
square feet (0.14 square meters) is required for each dryer.
will be adversely affected. Ignition problems and
To compensate for the use of registers or louvers used over the openings, this 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
the dryers.
EXAMPLE: For a bank of eight (8) dryers, two (2) unrestricted openings measuring 2 feet by 3 feet (0.61
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.
ALL
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 W ARRANTY.
