WARNINGS ABOUT USE AND OPERATION
DO NOT MODIFY THIS APPLIANCE. KEEP SHIELDS, GUARDS, AND COVERS IN PLACE. These
safety de ices are pro ided to protect e eryone from injury.
WARNING: Do not stop dryer before end of cycle time unless all items are quickly remo ed and spread out to
dissipate heat.
It is ABSOLUTELY ESSENTIAL that the dryer be grounded to a known earth (zero) ground in accordance
with local codes or, in the absence of local codes, with the latest editions of the National Electric Code, ANSI//NFPA
70 or Standard CSA C22.1 Canadian Electrical Code Part 1. This is not only for personal safety, but is necessary
for proper operation of the controller. Failure to do so will oid the warranty of the controller.
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 indi idual 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 ser ice
or other similar acti ities. The hour meter function adds only full hours to its reading. If the power is shut off e ery night,
any fraction of an hour of time that is on the machine at that time will be lost. Turning the power off e ery night
could also ha e 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-TEMPERATURE THERMOSTAT located to the right of
the motor on the rear of the cabinet. If the dryer ceases to operate, refer to your “Ser ice 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. It may be reset by inserting a wooden pencil or dowel
through the bushing in the co er.
DO NOT SPRAY AEROSOLS IN THE VICINITY OF THIS APPLIANCE while in operation.
THIS APPLIANCE SHALL NOT BE USED TO DRY OFF SOLVENTS OR DRY-CLEANING FLUIDS.

INSTALLATION AND OPERATING INSTRUCTIONS
UNCRATING AND PLACING DRYER
Tools Required: 3/4" (19 mm) hex socket & ratchet dri er, wood block 4" (100 mm) or 5" (125 mm) thick, a knife
and a groo e joint pliers, which will open to 1 3/8" (35 mm).
1. Remo e and discard packaging.
2. The crate base is attached to the dryer by (4) cap screws dri en upward from below the crate base. Remo e
crate base from dryer, by tipping dryer sidewise and place block under crate base rail in center of dryer.
Using a ratchet and 3/4" hex socket, remo e and discard (2) crating bolts from side, which is raised.
Remo e block from under crate base. Repeat for other side. Sa e the bolts for use if the dryer is e er
mo ed again.
3. With a walking motion mo e dryer completely off crate base. Sa e the crate base for use if the dryer is
e er mo ed again.
4. Slide unit into position where it will be installed. Adjust le eling legs, using the groo e joint pliers, to le el and
align dryer with adjacent units.
Note: If the dryer is e er mo ed again, the dryer should be re-mounted on its crate base and its crating bolts re-
inserted and tightened, in the re erse order as abo e.
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 the current Standard CAN/CGA-B149 (.1 or .2) Installation Code for Gas Burning Appliances or
Equipment, and local codes if applicable. Australian installations must meet installation requirements and pipe
sizing requirements of AS/NZA 5601. 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.
To connect the dryer to the supply piping, use a listed connector in compliance with the Standard for
Connectors for Gas Appliances, ANSI Z21.24 • CSA 6.10.
The appliance must not be installed behind a lockable door, a sliding door or a door with a hinge on the
opposite side to that of the tumble dryer, in such a way that a full opening of the tumble dryer door is
restricted.
2. INSTALLATION CLEARANCES: This unit may be installed at the following alco e clearances:
I. Left Side 0"
II. Right Side 0"
III. Back 18" (457 mm) (Certified for 1" (25 mm) clearance; howe er, 18" (457 mm) clearance is
necessary behind the motors to allow ser icing and maintenance.)
IV. Front 48" (1220 mm) (to allow use of dryer)
V. Top Refer to figure labeled “Vertical Clearance Dimensions”.
AB. Certification allows 0" clearance for wall framing at the top up to 18" (456 mm)
back from the front.
C. Howe er, a 1/4" (6 mm) clearance should be allowed so that the upper door can
be opened.
VI. Floor This unit may be installed upon a combustible floor.
Do not obstruct the flow of combustion and entilation air.
Maintain minimum of 1" (25 mm) clearance between duct and combustible material.
Refer to the label attached to the Belt Guard on the rear of the dryer for other installation information and
start-up instructions.

8514-234-001 REV N page 20
VERTICAL CLEARANCE DIMENSIONS
3. MAKE-UP AIR: Adequate make-up air must be supplied to replace air exhausted by dryers on all types of
installations. Refer to specifications for the minimum amount of make-up air opening to outside for each dryer.
This is a net requirement of effecti e area. Screens, grills or lou ers, which will restrict the flow of air, must be
considered. Consult the supplier to determine the free area equi alent for the grill being used. The source of
make-up air should be located sufficiently away from the dryers to allow an e en airflow to the air intakes
of all dryers. Multiple openings should be pro ided.
The sources of all make-up air and room entilation air mo ement to all dryers must be located away
from any dry cleaners. This is necessary so that sol ent apors will not be drawn into the dryer inlet
ducts. Dry cleaner sol ent apors will decompose in contact with open flame such as the gas flame present
in clothes dryers. The decomposition products are highly corrosi e and will cause damage to the dryer(s)
ducts and clothes loads.
The operation of this appliance may affect the operation of other types of gas appliances, which take
their air for safe combustion from the same room. Adequate entilation must be pro ided to a oid back
flow of gasses from other appliances in the same room. All other gas appliances should be tested with
the Dexter dryer in operation and all the windows and doors closed. If in doubt consult the appliance
manufacturer(s).
4. ELECTRICAL REQUIREMENTS. The electrical power requirements necessary to operate the unit satisfactorily
are listed on the serial plate located on the back panel of each dryer and in the specifications section of
this manual. The electrical connection should be made to the terminal board, on the rear of the unit. It is
absolutely necessary that the dryer be grounded to a known ground. Indi idual circuit breakers for each
dryer are required.
The installer must pro ide a disconnect switch which will interrupt both lines. It may be a local or national
requirement to pro ide an electrical interruption switch isible and accessible from the room in which the
dryer is installed. The wiring diagram is located on the belt guard on back of the dryer.
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 and in the specifications section of this
manual. The inlet gas connection to the unit is 1/2-inch [12.7] pipe thread for T-30 and T-50 and 3/4-inch
[19.1] for T-80 and T-120. Howe er, 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.
