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 are allowed during the OFF time.
may be pressed at any time to end the Wrinkle Guard cycle. Mechanical functions of the
dryer are allowed during the OFF time.
NOTE: Dryer can be stopped at any time by opening the main door or by pressing the “STOP/
CLEAR” key. There is no pause function.
NOTE: Pressing keyboard (touch pad) key “A,” “B,” “C,” “D,” or “F” will also start the dryer.
The six (6) preprogrammed drying cycles (“A” thru “F”) have been stored in the
microprocessor controller’s (computer’s) memory. Refer to the User’s Manual supplied
with the dryer for these preprogrammed cycles.

10. Check to insure that the basket (tumbler) starts in the clockwise (CW) direction. Additionally, check the
direction of the blower motor to insure 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.
be stopped and restarted several times for this air to be purged from the lines.
2) The dryer has one (1) burner that is controlled by a burner system module with Direct Spark
Ignition (DSI). There is one (1) spark ignition assembly (spark plug) and two (2) flame-probe
assemblies. If pilot ignition is not established after the first attempt, the heat circuit will be locked
out by the burner control module, until it has been manually reset. To reset the burner monitoring
system, press the black pilot test (reset) button on the burner control module.
assemblies. If pilot ignition is not established after the first attempt, the heat circuit will be locked
out by the burner control module, until it has been manually reset. To reset the burner monitoring
system, press the black pilot test (reset) button on the burner control module.
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 the gas valve pressure tap of the
dryer to assure that the water column (W.C.) pressure is correct and consistent.
