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 loading doors are closed and the lint drawer is closed.

3.Microprocessor (computer) system operational test -- to start the dryer;

a.Display will read "FILL."

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

c.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 (Fahrenheit) - 82º C (Celsius) - for 30 minutes drying time and have a 4 minute cool down period.

d.Dryer will now start, and the L.E.D. (light emitting diode) display will read "Dr30" (dry mode for 30 minutes) and count downwards in minutes.

NOTE: 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 touchpad key "A", "B", "C", "D", and "F" will also start the dryer. The six preprogrammed drying cycles ("A" thru "F") have been stored in the microprocessor (computer's) 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 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.
