WARNINGS ABOUT USE AND OPERATION
It is ABSOLUTELY ESSENTIAL that the dryer be grounded to a known earth (zero) ground. This is not only for
personal safety, but is necessary for proper operation.
KEEP SHIELDS, GUARDS AND COVERS IN PLACE. These safety devices are provided to protect everyone
from injury.
A DRYER SHOULD BE CONNECTED TO POWER FOR THREE (3) MINUTES before it is operated or before
a program change is made. Operation or program changes, which occur during this "power up" period, are subject
to loss in case of power interruption. After the initial three minutes, all programmed data is protected from power
interruptions of any length and the customer's individual cycle is protected up to 3 seconds. This is done without
batteries.
LEAVE THE ELECTRICAL POWER TO THE DRYER ON AT ALL TIMES except when necessary for
service or other similar activities. The hour meter function adds only full hours to its reading. If the power is shut
off every night, any fraction of an hour of time that is on the machine at that time will be lost. Turning the power off
every night could also have some effect on the long-term life of the memory after a number of years. Turning
power off occasionally won't affect the unit.
THIS DRYER IS EQUIPPED WITH AN OVER-TEMP ERATURE THERMOSTAT located on the right side
of the return lint hood assembly (open lower service door). Should the dryer cease to operate, refer to your
“Service Procedure and Parts Data” book for instructions.
CHECK THIS THERMOSTAT WHEN INSTALLING DRYER to assure it is not tripped. Impacts such as rough
handling in shipment, may trip the thermostat.

INSTALLATION AND OPERATING INSTRUCTIONS
COMMERCIAL DRYER
UNCRATING
1. Remove cardboard container and innerpack.
2. Complete the uncrating as described in the procedure listed on the instruction sheet taped to the loading door
glass.
DRYER INSTALLATION
1. CODE CONFORMITY. All commercial dryer installations must conform with local codes or, in the absence of
local codes, with the latest edition of the National Fuel Gas Code ANSI Z223. 1. Canadian installations must comply
with current Standard CAN/CGA-B149 (.1 or .2) Installation Code for Gas Burning Appliances or Equipment, and
local codes if applicable. The appliance, when installed, must be electrically grounded in accordance with the latest
edition of the National Electric Code, ANSI/NFPA70, or, when installed in Canada, with Standard CSA C22.1
Canadian Electrical Code Part 1.
2. INSTALLATION CLEARANCES: This unit may be installed at the following alcove clearance. (millimeters)
I. Left Side 0"
II. Right Side 0"*
III. Back 18" (457) (Certified for 1" (25) clearance; however, 18" (457) clearance is necessary behind the
belt guard to allow servicing and maintenance.)
IV. Front 48" (1220) (to allow use of dryer)
V. Top Refer to figure labeled “Vertical Clearance Dimensions”.
AB. Certification allows 0" clearance at the top 1" (25) back from the front. However, a 1/2" (12)
clearance is required to allow opening the upper service door.
CD. A 4" (102) clearance is required at the top between 1" (25) and 4" (102) from front.
E. A 10" (254) clearance is required from top at all other points.
VI. Floor This unit may be installed upon a combustible floor.
*Units may be installed in direct contact with an adjacent dryer, providing allowance is made for opening upper and
lower service doors.
Do not obstruct the flow of combustion and ventilation air.
Maintain minimum of 1" (25) clearance between duct and combustible material.
Refer to installation label attached to the inside surface of the upper door of the dryer for other installation
information.

3. MAKE-UP AIR. Adequate make-up air (1200 CFM) must be supplied to replace air exhausted by dryers on all
types of installations. Provide a minimum of 1.25 square foot make-up air opening to the outside for each dryer. This
is a net requirement of effective area. Screens, grills or louvers, which will restrict the flow of air, must be considered.
Consult the supplier to determine the free area equivalent for the grill being used.
The source of make-up air should be located sufficiently away from the dryers to allow an even airflow to the air
intakes of all dryers. Multiple openings should be provided.
NOTE: The following considerations must be observed for gas dryer installations where dry cleaners are
installed. The sources of all make-up air and room ventilation air movement to all dryers must be located
away from any dry cleaners. This is necessary so that solvent vapors will not be drawn into the dryer inlet
ducts. Dry cleaner solvent vapors will decompose in contact with an open flame such as the gas flame
present in clothes dryers. The decomposition products are highly corrosive and will cause damage to the
dryer(s), ducts and clothes loads.
4. ELECTRICAL REQUIREMENTS. (Refer to schematic and wiring diagram). This dryer is equipped with a
reconnectable motor and control transformer for use on 208–240V–1PH–60Hz or 110–125V–1PH–60Hz. The control
voltage is 24V, 60 Hz. The electrical power requirements necessary to operate the unit satisfactorily are listed on the
serial plate located on the back panel of each dryer. The electrical connection should be made to the terminal in the
control box on the rear of the unit, using a wire size adequate to handle the amperage and voltage listed on the serial
plate, but never smaller than No.12 AWG wire. The ground lug must be connected to a good external ground.
Individual circuit breakers for each unit are recommended. The schematic and wiring diagram is located on the
belt guard on the back of the machine.
5. GAS REQUIREMENTS. The complete gas requirements necessary to operate the dryer satisfactorily are listed
on the serial plate located on the back panel of the dryer.
The inlet gas connection to the unit is 1/2-inch pipe thread. However, the size of the piping to supply the dryer should
be determined by reference to the National Fuel Gas Code ANSI Z223.1A and consultation with the local gas supplier.
A joint compound resistant to the action of liquefied petroleum gases should be employed in making pipe
connections.
A drip tee should be provided in the gas piping entering the unit to catch dirt and other foreign articles.
All pipe connections should be checked for leakage with soap solution. Never check with an open flame.
For altitudes above 2,000 feet (610m) it is necessary to derate the BTU input. Contact your local distributor for
instructions.
L.P. gas conversion kits are available for this dryer. Contact your local distributor.
6. PRESSURE TESTING. The dryer and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of 1/2 psig.
The dryer must be isolated from the gas supply piping system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig.
7. EXHAUST INSTALLATION. (Refer to Figure 2 at the end of section 7.) Exhausting of the dryer(s) should be
planned and constructed so that no air restrictions occur. Any restriction due to pipe size or type of installation can
cause slow drying time, excessive heat, and lint in the room.
From an operational standpoint, incorrect or inadequate exhausting can cause a cycling of the high limit thermostat,
which shuts off the main burners and results in inefficient drying.
Individual exhausting of the dryers is recommended. All heat, moisture, and lint should be exhausted outside by
attaching a pipe of the proper diameter to the dryer adapter collar and extending it out through an outside wall. This
pipe must be very smooth on the inside, as rough surfaces tend to collect lint, which will eventually clog the duct and
prevent the dryer from exhausting properly. All elbows must be smooth on the inside. All joints must be made so the
exhaust end of one pipe is inside the next one downstream. The addition of an exhaust pipe tends to reduce the amount
of air the blower can exhaust. This does not affect the dryer operation if held within practical limits. For the most
efficient operation, it is recommended that no more than 20 feet (6m) of straight 8" diameter pipe be used with two
right angle elbows. When more than two elbows are used, two feet of straight pipe should be removed for each
additional elbow. No more than four right angle elbows should be used to exhaust a dryer.
