1. Clock Symbol. This symbol of a clock indicates that the
time in the display is counting down to zero.
2. Display. Displays the drying time, cooling time, drying
temperature, and diagnostics.
3. Hidden Keys. Used for programming in the coin mode –
increases or decreases the value in the display. In conjunc-
tion with the START button, these buttons are used to ad-
just the drying time, cooling time, temperature, clockwise
time, dwell time, counterclockwise time, and minutes per
coin.
4. Temperature LEDs. Indicate temperature setting.
5. DRYING LED. Illuminated when in the drying cycle.
6. Instructions. Instructions to start a drying cycle.
7. COOLING LED. Illuminated when in the cooling cycle or
when the display is currently showing the time for the
cooling cycle.
8. START. Starts or resumes the current program or cycle.
9. Temperature Select. This button toggles through the three
temperature selections.

time is displayed, the default (LOW) temperature setting LED
will be on until a different temperature setting is selected.
Power Failure
If a power loss occurs during operation, a cycle will not resume
until the START button is pressed. To cancel the remaining cy-
cle, press the internal CLEAR button.
Coin Operation
The tumble dryer run time is determined by the pre-programmed
run time per coin and the number of coins deposited into the tum-
ble dryer. The maximum time that can be accumulated and dis-
played is 99 minutes. The drying time is the difference between
the run time and the cooling time. The cooling time is pre-pro-
grammed to be 2 to 5 minutes. The drying temperature can be se-
lected from LOW, MEDIUM, or HIGH temperature settings by
pressing the TEMP button.
Coin Programming
The Coin board programming mode can only be entered when
"PAy" is displayed. DIP switch #7 must be in the off position.
Programming is enabled by setting DIP switch #8 to the ON posi-
tion.
The programming mode is entered by pressing and holding the
CLEAR button for three seconds.
The programming follows the following parameter order:
1. Tumble dryer run time per coin (DRYING), COOLING time,
HIGH temperature setpoint, MEDIUM temperature setpoint,
LOW temperature setpoint.
2. An LED will be on to indicate which parameter is flashing on
the display.
3. The hidden front panel increment and decrement keys are
used to change the value.
4. The CLEAR button is used to recall the default value.
5. The START button is used to step to the next parameter.
6. After the last parameter, "End" will be flashing.
7. Press the START button one last time to store the settings and
exit the program mode.
8. "PAy" will be displayed.
9. If it is determined that the data did not program correctly, the
error message "E2F" will flash for 4 seconds, and then the de-
fault coin parameters will be used.
The tumble dryer run time per coin is programmable for 1 to 20
minutes with the default preset to 10 minutes.
The cooling run time is programmable from 2 to 5 minutes with
the default preset to 2 minutes.
The three temperatures setpoints are programmable for 100ºF
[38ºC] to 185º/195ºF [85º/90ºC] with the following default set-
tings:
- HIGH equal to 185ºF [85ºC]
- MEDIUM equal to 150ºF [66ºC]
