INST ALLATION 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. UNPACKING/SETTING UP

Remove protective shipping material (i.e., plastic wrap and/or optional shipping box) from dryer.

NOTE: The access keys for the service doors are included in the information packet shipped in the

basket (tumbler). These keys should be removed and put in a safe place yet made accessible
because some will be needed throughout various phases in the installation of the dryer.

Dryers are shipped with a coin box and coin box faceplate ONLY. The coin box lock is not included and
must be purchased elsewhere or the lock can be ordered as a parts order from the manufacturer.

The dryer can be moved to its final location while still attached to the skid or with the skid removed. To 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 of the base, and two (2) are located in the front. Once the bolts are removed, slide the dryer off the
skid.

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. The dryer is equipped with four
(4) leveling legs, one (1) at each corner of the dryer base. The hex head adjustment bolts for the two (2) front
leveling legs are located directly behind the lower access door, and the rear two (2) adjustments are directly
behind the lower rear back (guard) panel.

To facilitate door closure and better tumbling action (and improved efficiency), the dryer should be tilted slightly
to the rear.

B. LOCATION OF THE DRYER

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 Canadian Installation Codes CAN/CGA-B149.1-M91 (Natural Gas) or CAN/
CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION.

113203-3 Maytag 7

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 or weather.

3. The dryer is for use in noncombustible locations.

Requirements in Section D).

5. Clearance provisions must be made from noncombustible construction as noted in this manual (refer to
Dryer Enclosure Requirements in Section C).

Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be
positioned approximately 2 feet (0.61 meters) away from the nearest obstruction, i.e., wall, for ease of
installation, maintenance, and service. (Refer to the illustration below.)

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 in an area where correct exhaust venting can be achieved as
noted in this manual (refer to Exhaust Requirements in Section E).

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).

8 Maytag 113203-3

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 E).

IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary.

9. The dryer must be installed with a proper exhaust duct connection to the outside.

10. The dryer must be installed with provisions for adequate combustion and make-up air supply.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6

months, inspect the exhaust ducting and remove any lint build up.

C. DRYER ENCLOSURE REQUIREMENTS

Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of
12-inches (30.48 cm [18-inches [45.72 cm] or more is recommended for ease of installation, maintenance, and
service]) above the dryer’s outer top, except along the front of the dryer which may be closed in if desired.

NOTE: Even though a minimum of 12-inches (30.48 cm) above the dryer’s outer top is acceptable, a

clearance of 18-inches (45.72 cm) or more is suggested for ease of installation and service
(electrical power connections).

NOTE: When fire sprinkler systems are located above the dryers, a minimum of 12-inches (30.48 cm)

above the dryer’s outer top is required.

NOTE: Allowances must be made for the opening of the control door.

Dryers may be positioned sidewall to sidewall. However, allowances must be made for the opening and closing
of the control door and the lint door. 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 on the previous page for details.

NOTE: Air considerations are important for proper and efficient operation.

113203-3 Maytag 9

D. FRESH AIR SUPPLY REQUIREMENTS

Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An
unrestricted source of 800 cfm (22.65 cmm) is necessary for each dryer. 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. This
area must be enlarged if louvers or registers cover the opening. 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. For example, for a bank of eight
(8) dryers, a total make-up air opening of 12 square feet (1.15 square meters) is required. Two (2) openings
measuring 2 feet by 3 feet (0.61 meters by 0.91 meters [6 square feet] [0.56 square meters]) are acceptable.
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-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.

IMPORTANT: Make-up air openings should not be located near ductwork exhaust outlets. If

make-up air openings are too close to the exhaust outlet, lint and fumes may be drawn
back into the dryer area through these openings.

NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
