ADC 450428 service manual

NOTE: Water column pressure requirements (measured at the pressure tap on the gas valve body):

Natural Gas - 3.5 inches water column (W.C.) - 8.7 mb.

L.P. Gas - 10.5 inches water column (W.C.) - 26.1 mb.

6.If computer program changes are required, refer to the Phase 6 OPL User’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.
