16 American Dryer Corp. 112174-7
NOTE: Gas model dryers are equipped with an ignition
system, which has internal diagnostics. If ignition is not
established after one time, the heat circuit in the ignition
module will attempt two more ignitions (total of three
ignition attempts). If there is no flame after the third
ignition attempt, the module will lock out until it is manually
reset. To reset the ignition system, open and close the
main door and restart the dryer.
A burner gas pressure measurement should be taken at the
gas valve outlet pressure tap of each gas valve to ensure
that the water column pressure is correct and consistent.
NOTE: Water column burner pressure requirements
(measured at the outlet pressure tap of the gas valve
body):
Natural Gas ........ 3.5 in WC (8.7 mb).
L.P. Gas ............. 10.5 in WC (26.1 mb).
IMPORTANT: There is no regulator provided in an L.P.
dryer. The water column pressure must be regulated at
the source (L.P. tank) or an external regulator must be
added to each dryer.
Make a complete operational check of all safety related
circuits:
Door Switch(es)
Hi-Limit Thermostats
Cycling Thermostats
Sail Switch
Make a complete operational check of all operating controls.
NOTE: If computer program changes are required, refer to
the computer programming section of the manual supplied
with the dryer.
The dryer should be operated through one complete cycle to
ensure that no further adjustments are necessary and that
all components are functioning properly.
Tumbler Coating
The tumbler is treated with a protective coating. We suggest
dampening old garments or cloth material with a solution of
water and nonflammable mild detergent and tumbling them
in the tumbler to remove this coating.
Preoperational Instructions __________
Coin Models
Microprocessor Controller (Computer)
When the microprocessor controller (computer) is in the ready

Insert coin(s). Once the correct “Amount to Start” has been
inserted, the L.C.D. will display “PUSH”.
Select temperature by pressing “HI,” “LO,” or “PERM PRESS.”
The cycle will start and the L.C.D. will display the Dry Cycle
selected and the remaining time.
The dryer will continue through the drying and cooling cycles,
until the vended time has expired.
NOTE: To stop the dryer, open the main door.
Continuation of the cycle will resume only after the door
has been closed and any of the three temperature
selection buttons is pressed.
Upon completion of the drying and cooling cycles, the tone
(buzzer) will sound and the dryer will go into the Anti-Wrinkle
Mode, if active, for up to 99 minutes, or until the main door or
lint drawer has been opened.
IMPORTANT: For more detailed information regarding the
microprocessor controller (computer) on your dryer, refer
to the microprocessor user’s manual included with the
dryer.

Discontinue power to the dryer either at the external
disconnect switch or the circuit breaker.
