I. PREOPERATIONAL TESTS
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should
be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to
marginal location (installation) conditions.
1. Turn on electric power to the dryer.
2. Make sure the loading doors are closed and the lint drawer is closed.
3. Microprocessor controller (computer) system operational test -- to start the dryer:
a. L.E.D. (light emitting diode) display will read “FILL.”
b. Press “E” (preprogrammed) cycle key on the touchpad of the keyboard.
c. L.E.D. display will quickly read ... “Ld30,” “Lc04,” and “F180” (unless special programs requested).
These codes mean that the dryer is in the timed mode, will operate with heat at 180º F (Fahrenheit) - 82º
C (Celsius) - for 30 minutes drying time, and have a 4 minute cool down period.
d. The dryer will now start, and the L.E.D. display will read “Dr30” (dry mode for 30 minutes) and count
downwards in minutes.
NOTE: The dryer can be stopped at any time by opening the main door or by pressing the
“CLEAR/STOP” key. To restart the dryer, press the “ENTER/START” key or a
preprogrammed cycle key (i.e., “E”).
NOTE: Pressing keyboard (touchpad) key “A,” “B,” “C,” “D,” and “F” will also start the dryer.
The six (6) preprogrammed drying cycles (“A” through “F”) have been stored in the
microprocessor controller (computer) memory. Refer to the Programming Manual
supplied with the dryer for these preprogrammed cycles.
4. Check to insure that the tumbler (basket) 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 hand 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: The dryer blower motor and impellor/fan shaft as viewed from the left hand 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.
5. 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 might have to
be stopped and restarted several times for this air to be purged from the lines.
