Adjusting the vertical louvers will vary the throw, the spread and the drop.
2
Adjusting the horizontal louvers will only vary the drop.
3
The velocity of the air will be 125 ft./min. at the minimum distance and 80 ft./min. at the maximum distance.
4
The velocity of the conditioned air at the bottom of the drop will be 50 ft./min. Drafts will occur if the drop extends into the occu-
pied level of the conditioned space.
