IMPORTANT: READ ALL INSTRUCTIONS BEFORE OPERATING!
SECTION I
TO OPERATE DRYER
1. Insert coins until “SELECT CYCLE” flashes in display. PD MODELS: Minutes purchased are also
shown on the display when cycle is selected.
2. Door must be closed before cycle selection is made.
3. Press fabric setting key pad for dryer cycle desired. After cycle is started, drying time will count down
whether door is open or closed.
“COOL DOWN” will appear in display near end of cycle.
WHITES & COLORS
1 MINUTE COOL DOWN TIME
PERMANENT PRESS
3 MINUTE COOL DOWN TIME
DELICATES
3 MINUTE COOL DOWN TIME
When a cycle is interrupted by opening the door, the selected cycle will flash in the display. To restart the
dryer, close door and press desired fabric setting key pad. The time will continue to count down.
Free cycles will terminate when the door is opened. Fabric selection can be changed at any time by
touching the desired fabric setting key pad.
SECTION II
GENERAL USER INFORMATION
BLANK DISPLAY
This condition indicates that the appliance is inoperative. Enter setup mode to view diagnostic code.
“0 MINUTES” SHOWING IN DISPLAY (Each Pocket)
This condition indicates that the appliance cannot be operated. Coins dropped or debit inputs during this
condition will be stored in escrow but cannot be used until normal operation is restored by opening and then
closing the door. If the door switch fails, it must be replaced before normal operation can be restored.
COLD START (Initial/First Use)
Appliance is programmed at the factory as follows:
Dryer
10 Min. dry time/quarter (coin 1)
$.25 dry price (fixed cycle with top off - PD Model)
WARM START (After Power Failure)
A few seconds after power is restored, if a cycle was in progress at the time of the power failure, the selected
cycle will flash in the display. This is to indicate the need for a fabric setting keypad to be
pressed to restart dryer.
2
PRICING
After the door is opened following the completion of a cycle, the display indicates the cycle price (unless set
for free operation). As coins or debit inputs arrive, the display will change to lead the user through the
initiation of a cycle.
There are four (4) types of pricing:
Fixed “Vend” Pricing
A dryer set up for “Fixed Cycle” operation can only accept additional time accumulated by increments
equal to the length of a complete dry cycle. A maximum of 99 minutes may be purchased; no additional
credit is given when 99 minutes is in the display.
Accumulator Pricing
If the price is set to one coin 1, then accumulator mode is in effect and Fixed Cycle
with Top Off option is selected. Cycle time can be purchased one coin at a time up to the maximum
time of 99 minutes. All money will be credited to a cycle with a single button press while in
accumulator pricing.
Fixed Cycle With Top Off Pricing
A dryer set to offer “Top Off” capability will allow time to be added to an existing dry cycle in increments
equal to the number of minutes of dry time per quarter (coin 1), up to 99 minutes, regardless of the cost
required to start the machine. No credit is given for coins or debit inputs entered when the control is
displaying 99 minutes.
Free Cycles
This is established by setting the cycle price to zero. When this happens “SELECT CYCLE” will appear
rather than a cycle price. Each press of a keypad will add the number of minutes of dry time per coin 1 to
the time. Any cycle started as a free cycle will automatically terminate when the door is opened.
Display
After the dryer has been installed and plugged in for the first time, the display will show “0 minutes.”
Once the unit has been plugged in and the dryer door opened and closed the display will show the price.
In dryers set for free cycles the display will flash “SELECT CYCLE.”

SECTION III
CONTROL SETUP PROCEDURE
IMPORTANT:
READ ALL INSTRUCTIONS BEFORE OPERATING.
The fabric setting key pads along with the digital display are used to setup the dryer controls.
The display can contain 3 numbers or letters and a decimal point. These are used to indicate the price, time
remaining and setup codes and related code values available for use in programming the appliance.
HOW TO USE THE KEYPADS TO PROGRAM THE CONTROLS
1. The WHITES & COLORS keypad is used to adjust the values associated with setup codes. Pressing the
keypad will increment the value by one (1). Rapid adjustment is possible by holding the keypad down.
2. The PERMANENT PRESS keypad will advance you through the setup codes. Pressing the keypad will
advance you to the next available setup code. Holding the keypad down will automatically advance
through the setup codes at a rate of one (1) per second.
3. The DELICATES keypad is used to select or deselect options.
START OPERATING Setup
CAUTION: The service access door must not be opened unless power is first disconnected from the
dryer.
Before proceeding it is worth noting that, despite all the options available, an owner can simply choose to
uncrate a new commercial machine, hook it up, plug it in and have a unit which operates.
PD units are preset at the factory for fixed cycle price with top off.
SECTION IV
SETUP CODES
The PERMANENT PRESS keypad will advance you from code to code. The WHITE & COLORS keypad
will change the code value. The DELICATES keypad will select or deselect options.
NOTE: On stacked dryers programming selections apply to both dryers.
The setup code is indicated by the one or two left hand characters. The setup code value is indicated by the
two or three right hand characters.
