FIGURE 6 - Removing Cover
VII. AIRFLOW ADJUSTMENTS
A. With the Air Door operating and the door in its full open position,
check to see that nothing is obstructing the air flow at the discharge
nozzle vanes.
B. Find the air stream split location. Hold a handkerchief, by its corners,
approximately 12" above the floor. Gently move the handkerchief
back and forth in the doorway. Make sure the air is being directed to
both the inside and the outside. The split location is indicated where
the handkerchief is vertical with minimal or no fluttering.
See Figure 7.
C. Adjust the discharge nozzle vanes so the split location is ap-
proximately 3" outside the doorway. This is accomplished by first
de-energizing the unit. Remove the cover housing, loosen the nozzle
vane locking screws and adjusting vanes.
D. Install remaining screws in cover housing.
