Refer to installation label attached to the rear guard of the dryer for other installation information.

8514-288-001 REV A PAGE 8
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 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.
4. ELECTRICAL REQUIREMENTS:
The electrical installation must be performed by a qualified electrical technician.
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 at the terminal blocks in the
control box on the rear of the unit using conductors rated at 75 C (167 F) and a wire size adequate to handle the
amperage and voltage listed on the serial plate (see the following table for recommended minimum sizes). It is
absolutely necessary that the dryer be grounded to a known (earth) ground (No. 8 AWG copper conductor
recommended). Knockouts are provided for the connection of 1-inch conduit for the power supply conductors
and 3/8-inch conduit for the external grounding conductor. The earth connection resistance should be checked
prior to operation.

For 240V power supplies, an earthed mid-point of a phase is required. The “high” leg of the 3-phase electrical
supply (delta) must be connected to terminal L3. A neutral is required for all electrical supply variations; see the
wiring diagram affixed to the belt guard on the back of the dryer.
The installation must meet the electrical requirements of the country, state and locality of the installation. The
installer may be required to provide a disconnect switch which will interrupt all lines. It may be a local or national
requirement to provide an electrical interruption switch visible and accessible from the room in which the dryer is
installed. The wiring diagram is located on the belt guard on the back of the dryer.
IMPORTANT: TRANSIENT VOLTAGE SURGE SUPPRESSORS
Like most electrical equipment your new machine can be damaged or have its life shortened by voltage surges
due to lightening strikes which are not covered by factory warranty. Local power distribution problems also can
be detrimental to the life of electrical components. We recommend the installation of transient voltage surge
suppressors for your new equipment. These devices may be placed at the power supply panel for the complete
installation and don’t require an individual device for each machine.
These surge protectors help to protect equipment from large spikes and also from small ongoing spikes in the
power that occur on a day to day basis. These smaller surges can shorten overall life of electrical components of
all types and cause their failure at a later date. Although they can’t protect against all events, these protective
devices have a good reputation for significantly lengthening the useful life of electronic components. Electronic
components are helped to have a longer useful life when they are supplied with the clean stable electrical power
they like.
We are including the following names and phone numbers of a few suppliers of these devices for those who
don’t currently have a source.

6. EXHAUST INSTALLATION. 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 heaters 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. Do not assemble pipe or

8514-288-001 REV A PAGE 10
elbows with screws or other fastening means that will extend in to the pipe or elbows and catch lint. 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 14' (4.3 m) of straight 6" (152 mm) diameter pipe is used with two right angle elbows. When more than
two elbows are used, 2' (610 mm) of straight pipe should be removed for each additional elbow. No more than
four right angle elbows should be used to exhaust a dryer.
If the exhaust pipe passes through a wall, a metal sleeve of slightly larger diameter should be set in the wall
and the exhaust pipe passed through this sleeve. This practice is required by some local codes and is
recommended in all cases to protect the wall. This type of installation should have a means provided to prevent
rain and high winds from entering the exhaust when the dryer is not in use. A hood with a hinged damper can
be used for this purpose. Another method would be to point the outlet end of the pipe downward to prevent
entrance of wind and rain. In either case, the outlet should be kept clear, by at least 24"
(610 mm), of any objects, which would cause air restriction.
Never install a protective screen over the exhaust outlet.
When exhausting a dryer straight up through a roof, the overall length of the duct has the same limits as
exhausting through a wall. A rain cap must be placed on top of the exhaust and must be of such a type as to be
free from clogging. The type using a cone shaped “roof” over the pipe is suitable for this application.
Exhausting the dryer into a chimney, a wall, a ceiling, an attic, a crawl space, or a concealed space of a
building is not permitted. In any case, there is a danger of lint buildup, which can be highly combustible.
Installation of several dryers, where a main discharge duct is necessary, will need the following considerations
for installation. Individual ducts from the dryers into the main discharge duct should be at a 45-degree angle in
the direction of discharge airflow.
NOTE: Never install the individual ducts at a right angle into the main discharge duct. The individual ducts from
the dryers can enter at the sides or bottom of the main discharge duct. The main duct can be rectangular or
round, provided adequate airflow is maintained. For each individual dryer, the total exhausting (main discharge
duct plus duct outlet from the dryer) should not exceed the equivalent of 14' (4.3 m) and two elbows. The
diameter of the main discharge duct, at the last dryer, must be maintained to exhaust end.
NOTE: A small diameter duct will restrict airflow; a large diameter duct will reduce air velocity - both
contributing to lint build up. An inspection door should be provided for periodic clean out of the main duct.
NOTE: STATIC BACK PRESSURE should be a maximum of 0.3 at the rear exhaust outlet of the
dryer. If multiple dryers are connected to the common duct, ensure the back draft damper is
installed properly.
DRYER SHUTDOWN
To render the dryer inoperative, disconnect electrical supply to the dryer.
IT IS RECOMMENDED THAT THE INSTALLER TEST THE DRYER FOR OPERATION AND INSTRUCT THE
USER BEFORE LEAVING THE INSTALLATION.
Caution - A clothes dryer produces combustible lint and should be exhausted outdoors. The area around the
clothes dryer should be kept free of lint.

8514-288-001 REV A PAGE 15
OPERATING INSTRUCTIONS
To dry a load of items, you must choose one of the five-programmed dry cycles. Each of
these five dry cycles may be modified in two different ways to match your load. Please refer
to the “Permanent Dryer Controller Programming” or “Temporary Dryer Controller
Programming” section of this manual.
There are two parts to each dry cycle. The first part is the heating time, which is when the
heating elements are cycled on and off according to the temperature setting in the dry cycle
program. The second part is the cool down time, which is after the heating part of the dry
cycle, and is when the tumbler continues to turn, but no heat is applied.
There will always be at least two minutes of cool down time for each dry cycle. The
maximum amount of cool down time is 60 minutes if the controller has a red dot sticker or 15
minutes if the controller has no red dot sticker.
The five dry cycle default values are shown in the “DRYER CONTROLLER FACTORY DEFAULT
PROGRAM SETTINGS” table in this manual.
To improve the drying capabilities of this dryer, you should always separate (untangle) the
individual articles in your load before using the dryer.
In the following instruction steps, things that are displayed on the 4-digit numerical display
will be in “quotation marks” and any touch pad switches on the dryer controller that physically
need to be pressed will be in CAPITAL AND BOLD LETTERS.
1) Place your untangled load into the dryer tumbler and close the dryer loading door. Notice
that the dryer controller 4-digit numerical display should show the word “LOAd”. If it does
not show this word, then press and release the STOP touch pad switch on the dryer
controller twice.
2) Press and release the UP or DOWN touch pad switch on the dryer controller to select a
dry cycle.
3) Once the desired dry cycle is selected, press and release the START touch pad switch.
After the START touch pad switch of the dryer controller is pressed, the dryer tumbler
will start rotating and the two-digit total dry cycle time, along with a decimal point, will
appear on the dryer controller display.
The time shown on the dryer controller display will count down to the programmed cool
down time. At that time, the display will change from the decimal point and two-digit
number to a letter “C” and two digits.
The letter “C” represents the cool down portion of the dry cycle. The two digits
represent the amount of time remaining in the dry cycle. The two-digit time, shown on the
dryer controller display, will count down to zero.
When the time decrements to zero, the dryer controller display will flash the word “donE”
and the end of cycle tone will sound.
At that point, the wrinkle free cycle will automatically begin. This cycle will wait two
minutes, if the door is not opened or the STOP touch pad switch on the dryer controller is
not pressed, and then rotate the tumbler for 10 seconds and stop. These two minutes of
idle time and 10 seconds of tumble time will repeat a total of 10 times, at which time the
wrinkle free cycle stops. The tumbler will not rotate again until a new dry cycle is started.

8514-288-001 REV A PAGE 16
During the wrinkle free cycle, the heating elements will not be operated and there will be
no heat applied to the load. The word “donE” will also continue to flash and do so even
after the wrinkle free cycle is finished. When the dryer loading door is opened, or the
STOP touch pad switch is pressed, the word “donE” will change to the word “LOAd” on the
dryer controller display. The dryer will then be ready for another dry cycle.
During the dry cycle, either pressing the STOP touch pad switch on the dryer controller
or opening the dryer loading door, will stop the dry cycle and not clear it. If you press the
STOP touch pad switch on the dryer controller and then open the dryer loading door, the
dry cycle will not be cleared. However, if you open (or open and close) the dryer loading
door and then press the STOP touch pad switch on the dryer controller, the present dry
cycle will be cleared and the word “LOAd” will appear on the dryer controller display.
There are two jumpers and one push button on the component side of the dryer
controller printed circuit board.
The jumper located at the lower right side of the circuit board controls whether the
controller display shows and operates in the Fahrenheit or Celsius mode. This jumper is
labeled as TEMP SELECT and has three pins. The bottom and middle pins are for Celsius
and the top and middle pins are for Fahrenheit, which is indicated by the letter C for
Celsius and the letter F for Fahrenheit.
The other jumper, located at the upper right side of the component side of the dryer
controller circuit board, is used for choosing either a reversing or non-reversing type of
dryer. This jumper is labeled as REV and NON-REV. This jumper must be in the non-
reversing position, which are the bottom and middle pins. If the jumper is in the reversing
position, the heating part of the dry cycle will not operate properly. The dryer will not
reverse direction either.
The push button, which is located at the lower middle side of the component side of the
dryer controller circuit board, is used to reset all five of the dry cycles to the factory default
settings. It is labeled as DEFAULT SETTINGS. Even the dry cycles that have been
modified using the permanent programming procedure will be changed back to the factory
default settings when using this push button. This push button must be pressed and held
for at least three seconds with power applied to the dryer controller circuit board.
TEMPORARY DRYER CONTROLLER PROGRAMMING
The temporary programming mode will allow the change of the stored dry cycle settings in
the dryer controller for one complete dry cycle. After the dry cycle is complete, the default
settings that existed before the temporary change are restored. The temporary dry cycle can
be stopped and cleared at any time during the dry cycle operation.
To temporarily change a dryer controller cycle, follow the procedures below. Things that are
displayed on the 4-digit numeric display will be in “quotation marks”. Switches on the dryer
controller touch pad that physically need to be pressed will be in CAPITAL AND BOLD
LETTERS.
If, at any time, you want to escape the temporary programming mode while changing the
program settings, you can press the STOP touch pad switch on the dryer controller if the 4-
digit numeric display is not flashing. The SELECT/ENTER touch pad switch on the dryer
controller can be pressed and released to enter the flashing value shown on the 4-digit
numeric display and allow you to escape.

8514-288-001 REV A PAGE 17
If you press and release the STOP touch pad switch on the dryer controller, when the 4-
digit numeric display is not flashing, the temporary changes to the dry cycle program will be
cancelled. The stored dry cycle settings that existed before the temporary change will then be
restored.
If, at any time, you want to start the temporary dry cycle during the temporary
programming mode, press and release the START touch pad switch on the dryer controller if
the 4-digit numeric display is not flashing. The SELECT/ENTER touch pad switch on the
dryer controller can be pressed and released to enter the flashing value shown on the 4-digit
numeric display and allow you to start the temporary dry cycle. If you start the temporary dry
cycle, the 4-digit numerical display will change to the total dry time and count down to 0 as
the dry cycle progresses.
PROCEDURE
1) Make sure the dryer is not in a dry cycle. The 4-digit numeric display on the dryer
controller will show “LOAd” when the dryer is not in a dry cycle.
2) Press and release the UP or DOWN touch pad switch on the dryer controller to chose the
dry cycle that you want to change (dry cycle 1 through 5). The dry cycle LED will
illuminate to indicate which dry cycle you are choosing. If you press and hold it down
either the UP or DOWN touch pad switch, the controller will sequence through the five dry
cycles.
3) Press and release the CYCLE touch pad switch on the dryer controller once you have
chosen the dry cycle you want to change. After you press the CYCLE touch pad switch,
the programming LED and the dry time LED will illuminate, the dry cycle LED will remain
illuminated, and the total dry time will be displayed on the 4-digit numeric display.
4) Press and release the UP or DOWN touch pad switch on the dryer controller to change the
total cycle time. Once either the UP or DOWN touch pad switch is pressed, the dry time
LED and the total dry time on the 4-digit numeric display will flash. If you press and hold
down either the UP or DOWN touch pad switch, you will increment (UP touch pad switch)
or decrement (DOWN touch pas switch) through the total dry times available (1 through
60 minutes). This displayed dry time includes the cool down time along with the heated
time. To not change the total dry time, do not press either the UP or DOWN touch pad
switch to change the total dry time.
5) Press and release the SELECT/ENTER touch pad switch on the dryer controller. Once the
SELECT/ENTER touch pad switch is pressed and released, the dry time LED will switch
off, the dry cycle LED and programming LED will remain on, the temperature LED will
illuminate, and the drying temperature will be shown on the 4-digit numeric display.
6) Press and release the UP or DOWN touch pad switch on the dryer controller to change the
drying temperature. Each press and release of either the UP or DOWN touch pad switch
will either increase or decrease the temperature by five degrees Fahrenheit or three
degrees Celsius, depending on how your dryer controller is set up. Once either the UP or
DOWN touch pad switch is pressed, the temperature LED and the drying temperature on
the 4-digit numeric display will flash. If you press and hold down either the UP or DOWN
touch pad switch, you will increment (UP touch pad switch) or decrement (DOWN touch
pad switch) your way through the available drying temperatures (105OFahrenheit or 41O
Celsius, up to 195OFahrenheit or 90OCelsius). If you do not want to change the drying
temperature, do not press either the UP or DOWN touch pad switch. Go to the next step.

7) Press and release the SELECT/ENTER touch pad switch on the dryer controller. Once the
SELECT/ENTER touch pad switch is pressed and released, the temperature LED will
switch off, the dry cycle LED and programming LED will remain on, the cool down LED will
illuminate, and the cool down time will be shown on the 4-digit numeric display.
8) Press and release the UP or DOWN touch pad switch on the dryer controller to change the
cool down time. Once either the UP or DOWN touch pad switch is pressed, the cool down
LED and the cool down time on the 4-digit numeric display will flash. If you press and hold
down either the UP or DOWN touch pad switch, you will increment (UP touch pad switch)
or decrement (DOWN touch pad switch) through the cool down times available (2 through
60 minutes if the controller has a red dot sticker or 2 through 15 minutes if the controller
has no red dot sticker). To not change the cool down time, do not press either the UP or
DOWN touch pad switch. Go to the next step.
9) Press and release the SELECT/ENTER touch pad switch on the dryer controller. Once the
SELECT/ENTER touch pad switch is pressed and released, the cool down LED and the
programming LED will switch off, the dry cycle LED will remain on, and the flashing cool
down time on the 4-digit display will stop flashing and remain.
10)At this point, you have two choices.
1) You can perform the modified dry cycle by pressing and releasing the START touch pad
switch on the dryer controller. If you start the modified cycle, the total dry time will
appear on the 4-digit numeric display and it will count down to 0 as the dry cycle
progresses.
2) You can clear the modified dry cycle program by pressing and releasing the STOP touch
pad switch once. If you choose to clear the modified dry cycle, the 4-digit numeric display
will change to “LOAd”.
TEMPORARY DRYER CONTROLLER PROGRAMMING EXAMPLE
REQUIREMENTS: Dry a load with 40 minutes of actual heat at 1850F and five minutes of
cool down.
The following procedure will show you how to temporarily modify the existing dry cycle 1
program for one cycle of drying. It is based on the assumption that the factory defaults have
not been permanently changed. If they have been changed, the steps of this procedure will
be the same, but the values that are displayed will be different. The amount of times that the
UP or DOWN touch pad switches of the dryer controller must be pressed and released may
also be different.
If you want the change to be permanent, go to the “PERMANENT DRYER CONTROLLER
PROGRAMMING” section of this manual.
PROCEDURE
1) After the load has been placed in the dryer, press and release the UP or DOWN
touch pad switch on the dryer controller until the LED for dry cycle 1 is illuminated.
2) Press and release the CYCLE touch pad switch on the dryer controller. You will see
the number “35” on the dryer controller display. The programming LED and dry
time LED will be illuminated.
3) Press and release the UP touch pad switch on the dryer controller 10 times so the
display will show a flashing “45”. When the UP touch pad switch is pressed the first

8514-288-001 REV A PAGE 19
time, the number “36” will be flashing on the dryer controller display. Each number
after that will also flash.
4) Now, press and release the SELECT/ENTER touch pad switch on the dryer
controller. The number “45” will stop flashing and the dry time LED will turn off.
The dryer controller display will now show “180”, the temperature LED will
illuminate, and the programming LED and dry cycle 1 LED will remain on.
5) Press and release the UP touch pad switch on the dryer controller one time so the
controller display will show a flashing “185”. Each press of the UP touch pad switch
will increment the temperature by five degrees.
6) Now, press and release the SELECT/ENTER touch pad switch on the dryer
controller. The number “185” will stop flashing and the temperature LED will turn
off. The dryer control display will now show a number “5”, the cool down LED will
illuminate, and the programming LED and dry cycle 1 LED will remain on.
7) Press and release the SELECT/ENTER touch pad switch on the dryer controller,
since the desired cool down time is five minutes. After you press the
SELECT/ENTER touch pad switch on the controller, the cool down LED and
programming LED will turn off. The controller display will remain at “5” and the
cycle 1 LED will remain on.
You are now ready to start the new dry cycle. This new dry cycle will be in effect for one
dry cycle only. After the dry cycle is done, or if the STOP touch pad switch on the dryer
controller is pressed and released twice, consecutively, the cycle 1 program will revert to
the factory default settings.
If you press the START touch pad switch on the dryer controller, the controller display
will change from the number “5” to the number “45” and dry cycle 1 will begin.
PERMANENT DRYER CONTROLLER PROGRAMMING
The permanent programming mode will allow the change of the stored dry cycle settings in
the dryer controller until the operator physically changes them again. The factory default
settings can be restored in the dryer controller by pressing the default settings pushbutton on
the back (component) side of the dryer controller circuit board. It is labeled and located at
the lower middle side of the printed circuit board, as you face the component side of the
board. It must be pressed and held down for at least three seconds with power applied to the
dryer controller circuit board.
To permanently change a dryer controller cycle, follow the procedure below. Things that are
displayed on the 4-digit numeric display will be in “quotation marks”. Touch pad switches that
physically need to be pressed will be in CAPITAL AND BOLD LETTERS.
If, at any time, you want to escape the permanent programming mode while changing the
settings, you can press the STOP touch pad switch on the dryer controller if the 4-digit
numeric display is not flashing. The SELECT/ENTER touch pad switch on the dryer controller
can be pressed and released to enter the flashing value shown on the 4-digit numeric display
and allow you to escape.
PROCEDURE
1) Make sure the dryer is not in a dry cycle. The 4-digit numeric display on the dryer
controller will show “LOAd” when the dryer is not in a dry cycle.

2) Press and release the PROG touch pad switch on the dryer controller.
3) Press and release the UP touch pad switch on the dryer controller. The programming LED
will illuminate and the 4-digit numeric display on the dryer controller will change to “Prog”.
4) Press and release the UP or DOWN touch pad switch on the dryer controller to choose the
dry cycle you want to change (dry cycle 1 through 5). The dry cycle LED will illuminate to
indicate which dry cycle you are choosing. If you press and hold down either the UP or
DOWN touch pad switch, the controller will sequence through the five dry cycles.
5) Press and release the SELECT/ENTER touch pad switch on the dryer controller when you
have chosen the dry cycle that you want to change. After you press the SELECT/ENTER
touch pad switch, the dry time LED will illuminate, the dry cycle LED and the programming
LED will remain illuminated, and the total dry time will be displayed on the 4-digit numeric
display.
6) Press and release the UP or DOWN touch pad switch on the dryer controller to change the
total dry time. Once either the UP or DOWN touch pad switch is pressed, the dry time
LED and the total dry time on the 4-digit numeric display will flash. If you press and hold
down either the UP or DOWN touch pad switch, you will increment (UP touch pad switch)
or decrement (DOWN touch pad switch) through the total dry times available (1 through
60 minutes). This displayed dry time includes the cool down time along with the heated
time. To not change the total dry time, do not press either the UP or DOWN touch pad
switch. Go to the next step.
7) Press and release the SELECT/ENTER touch pad switch on the dryer controller. Once the
SELECT/ENTER touch pad switch is pressed and released, the dry time LED will switch
off, the dry cycle LED and programming LED will remain on, the temperature LED will
illuminate, and the drying temperature will be shown on the 4-digit numeric display.
8) Press and release the UP or DOWN touch pad switch on the dryer controller to change the
drying temperature. Each press and release of either the UP or DOWN touch pad switch
will either increase or decrease the temperature by five degrees Fahrenheit or three
degrees Celsius, depending on how your dryer controller is set up. Once either the UP or
DOWN touch pad switch is pressed, the temperature LED and the drying temperature on
the 4-digit numeric display will flash. If you press and hold down either the UP or DOWN
touch pad switch, you will increment (UP touch pad switch) or decrement (DOWN touch
pad switch) your way through the available drying temperatures (105OFahrenheit or 41O
Celsius, up to 195OFahrenheit or 90OCelsius). If you do not want to change the drying
temperature, do not press either the UP or DOWN touch pad switch. Go to the next step.
9) Press and release the SELECT/ENTER touch pad switch on the dryer controller. Once the
SELECT/ENTER touch pad switch is pressed and released, the temperature LED will turn
off, the dry cycle LED and programming LED will remain on, the cool down LED will
illuminate, and the cool down time will be shown on the 4-digit numeric display.
10)Press and release the UP or DOWN touch pad switch on the dryer controller to change the
cool down time. Once either the UP or DOWN touch pad switch is pressed, the cool down
LED and the cool down time on the 4-digit numeric display will flash. If you press and hold
down either the UP or DOWN touch pad switch, you will increment (UP touch pad switch)
or decrement (DOWN touch pad switch) through the cool down times available (2 through
60 minutes if the controller has a red dot sticker or 2 through 15 minutes if the controller
has no red dot sticker). To not change the cool down time, do not press either the UP or
DOWN touch pad switch. Go to the next step.
