30 American Dryer Corp. 113068-7
NOTE: Mechanical functions of the dryer are not allowed during the ON time. The blower (fan)
must be OFF to perform mechanical functions. However the “STOP/CLEAR” key may be
pressed at any time to end the Wrinkle Guard Cycle. Mechanical functions of the dryer is
allowed during the OFF time.
NOTE: The dryer can be stopped at any time by pressing the “STOP/CLEAR” key. If the
temperature is above the Cool Down set point when the “STOP/CLEAR” key is pressed, the
dryer will go into a Cool Down Cycle. If the “STOP/CLEAR” key is pressed again, at this
point the cycle that was in progress will be canceled and returned to the “READY” state. If
the temperature is below the Cool Down set point, the cycle that was in progress will be
canceled, and go into Wrinkle Guard Cycle.
NOTE: Pressing keypad key “A,” “B,” “C,” “D,” or “F” will also start the dryer. The six
preprogrammed drying cycles (“A” thru “F”) have been stored in the microprocessor
controller’s (computer’s) memory. Refer to the Programming Manual supplied with the dryer
for these preprogrammed cycles.
10. Check to ensure that the basket (tumbler) starts in the clockwise (CW) direction. Additionally, check the
direction of the blower motor to ensure that it rotates in the counterclockwise (CCW) direction as viewed
from the left side of the dryer. If it does, the phasing is correct. If the phasing is incorrect, reverse two (2)
of the leads at L1, L2, or L3 of the power supply connections made to the dryer.
IMPORTANT: Dryer blower motor and impellor/fan shaft as viewed from the left side of the dryer
must turn in the counterclockwise (CCW) direction, otherwise the dryer efficiency will
be drastically reduced, and premature component failure can result.
11. Heat Circuit Operational Test
a. Gas Models
1) When the dryer is first started (during initial start-up), the burners have a tendency not to ignite on
the first attempt. This is because the gas supply piping is filled with air, so the dryer may have to be
stopped and restarted several times for this air to be purged from the lines.
2) The dryer has two (2) burner boxes and each burner has its own Direct Spark Ignition (DSI)
module and spark ignitor/flame-probe assembly. If ignition
is not established after first attempt, the
heat circuit DSI module will lockout until it is manually reset. To reset the DSI system, open and
close the loading doors and restart the dryer (press “ENTER/START” key).
If one (1) burner lights and the other does not, then the system will shut both burners off and the
burner fault code
will be displayed showing, which of the two (2) burners failed to ignite.
NOTE: During the purging period, verify that ALL gas shutoff valves are open.
3) Once ignition is established, a gas pressure test should be taken at each gas valve pressure tap of
the dryer to assure that the water column (W.C.) pressure is correct and consistent.
NOTE: Water column pressure requirements (measured at both gas valve pressure taps)...
Natural Gas .......................... 3.5 inches (8.7 mb) water column.
Liquid Propane (L.P.) Gas .... 10.5 inches (26.1 mb) water column.
