6. If computer program changes are required, refer to the Phase 6 OPL Operatorî‚’s Manual (ADC Part
No. 113022) for details.
7. The dryer should be operated through one complete cycle to assure that no further adjustments are necessary
and that ALL components are functioning properly.
8. Check the electric service phase sequence. While the dryer is operating, check to see if the blower wheel is
rotating in the proper direction. Looking from the front, the blower wheel should spin in the clockwise (CW)
direction. If so, the phasing is correct. If the phasing is incorrect, reverse two (2) leads at connections L1, L2,
or L3 of power supply to the dryer.
