J. 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 main door is closed and the lint drawer is securely in place.

3.System controls operational test -- to start the dryer ...

a. Microprocessor (computer) controls ...

1)L.E.D. (light emitting diode) display will read "FILL."

2)Press the "E" (preprogrammed) cycle key on the touchpad of the keyboard.

3)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 and will operate with heat of 180º F (82º C) for 30 minutes drying time and have a 4 minute cool down period.

4)Dryer will now start and the L.E.D. display will read "Dr30" (dry mode for 30 minutes) and count down in minutes.

NOTE: The dryer can be stopped at any time by opening main door or by pressing the "CLEAR/STOP" key. To restart the dryer, press the "ENTER/START" key or preprogrammed cycle key (i.e., "E").

NOTE: Pressing touchpad (keypad) 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 (computer's) memory. Refer to the computer programming manual supplied with dryer for these preprogrammed cycles.

b.Timer (manual) controls system operational test -- to start the dryer ...

1)Turn "HEAT" timer knob (clockwise [CW]) for a time desired (i.e., 1 minute to 60 minutes).

2)Make the desired temperature selection (i.e, "HIGH," "LOW," or "PERM PRESS") at the rocker switch.

3)Press "PUSH TO START" switch button and the dryer will start.

4)To stop the dryer, open the main door.
