4 American Dryer Corp. 113217- 5

WARNING: DO NOT dry mop heads. Contamination by wax or flammable solvents will create a fire

hazard.

WARNING: DO NOT use heat for drying articles that contain plastic, foam, sponge rubber, or similarly

textured rubber materials. Drying in a heated basket (tumbler) may damage plastics or
rubber and may be a fire hazard.

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.

8. For personal safety, the dryer must be electrically grounded in accordance with local codes and/or the National

Electrical Code ANSI/NFPA NO. 70-LATEST EDITION or in Canada, the Canadian Electrical Codes Parts 1 & 2
CSA C22.1-1990 or LATEST EDITION.

NOTE: Failure to electrically ground the dryer properly will VOID THE WARRANTY.

9. UNDER NO CIRCUMSTANCES should the dryer door switch, lint drawer switch, or heat safety circuits ever be

create a fire hazard.

12. DO NOT operate steam dryers with more than 125 psi (8.61 bar) steam pressure. Excessive steam pressure can

damage steam coil and/or harm personnel.

13. Replace leaking flexible hoses or other steam fixtures immediately. DO NOT operate the dryer with leaking

flexible hoses. PERSONAL INJURY OR FIRE COULD RESULT.

SECTION III

INSTALLATION 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 Z223.1-LATEST 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/CGA­B149.2-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. REASSEMBLY OF DRYER

IMPORTANT: Always keep the basket (tumbler) section of the dryer in an upright position when

moving it.

WARNING: Twisting of the gas line may cause premature failure.

NOTE: On a yearly basis flex gas lines must be inspected for leaks, if any signs of fraying or abrasion

are found, the gas line must be replaced.

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

The tilting dryer is made in many loading and unloading options. Please refer to the reassembly instructions on the
following pages for your particular style of dryer.

If a steam dryer is shipped in two (2) pieces, the steam coil may have been removed from the top of the basket (tumbler)
section and shipped with the base. If this is the case, lift the steam coil onto the top of the basket (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 the
1/4” hardware supplied. There are three (3) panels that cover the front, right side, and rear of the steam coil. Fasten
these in proportion also. Reconnect the steam and condensate pipe unions to the coil. These pipes run down to the flex
hoses in the base.

Reassembly Instructions For Forward Tilt Dryers:

Lift the basket (tumbler) section onto the base.

Tilt dryers have tilting pistons in the base. Non-tilt dryers use piston posts in the base. On the top of each piston is a
clevis block. Use the four (4) 1/2” x 1-1/8” long hex head bolts with lock washers to secure each piston clevis block to
the bottom of the basket (tumbler) section. (Refer to Piston/Post Reconnection [top] View 1 on the previous page.)

1. Gas Models

The flexible gas hose union is disconnected when the dryer is shipped in two (2) pieces. The flexible gas hoses are
located in the right side of the base. Insert the flexible hoses with the union half up through the hole on the bottom
of the basket (tumbler) section and retighten the union. The flex hoses must not be kinked. (Refer to [bottom left]
View 2 on the previous page.)

2. Steam Models

Both the 2” steam supply line and the 1-1/4” condensate return line flexible hose unions are disconnected when the
dryer is shipped in two (2) pieces. The flexible hoses are located in the right side of the base. Insert both flexible
hose union halves up through the holes on the bottom of the basket (tumbler) section and retighten the unions. The
flex hoses must not be kinked. (Refer to [bottom right] View 2 on the previous page.)

3. There are two (2) electrical reconnections:

a. A 24-pin plug and cable and a 10-pin plug and cable are located in the right side of the base. This must be lifted

up and reconnected into the mating socket located at the bottom of the right basket (tumbler) section.

b. The basket (tumbler) section power cable must be lifted up from the base and reconnected into the junction

box next to the basket (tumbler) drive motor in the left side of the basket (tumbler) section.

Make sure that reconnected cables have enough slack in them to allow the dryer to tilt freely in both directions.

4. Reattach the tilt guard panels:

a. Use 1/4-20 self-tapping screws to secure the hinged rear tilt guard panel on the rear of the base.

b. Use round head screws to secure the tilt guard panel to the rear of the dryer.

c. Use 1/4-20 self-tapping screws to secure the right and left side tilt panel.

d. Use round head screws to secure the right and left lower side panels to the basket (tumbler) section.

5. Secure the 24” diameter exhaust duct transition piece to the dryer’s rectangular exhaust duct with the
1/4-20 self-tapping screws supplied with the dryer. The exhaust duct exits from the rear of the base.

6. On dryers equipped with an optional automatic (piston operated) load door, reconnect the two (2) poly-flo air lines
that run from the base up to the door pistons. Located in the right side of the base.

7. Reconnect the 1/4” poly-flo air line, which runs from the base up to the steam damper solenoid valve, which is
located on the top of the dryer.
