“PURGE CYCLE” CALIBRATION
PROCEDURE
The Purge Cycle control adjustment (see figure V.A.1) determines
the time span that the Bleed and Process solenoid valves are
energized during either a Bank A or B Purge Cycle.
Turning the adjustment screw fully clockwise equals a minimum
Purge Cycle of approximately one (1) minute. Turning the
adjustment screw fully counterclockwise equals a maximum
Purge Cycle of nine (9) to thirteen (13) minutes.

Cycle setting. See figures V.A.1 and V.B.1.
