1. 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 occupied
level of the conditioned space.
