1Unit resistance is based on a wet indoor coil and clean filters.
2
Available static pressure in IWG to overcome the resistance of the duct system and any accessoires added to the unit. Refer to the table above for additional motor and drive data and to the
table on page 7 for the resistance of these accessories.
3
Refer to Form 515.41-AD1 for blower performance curves.

1Adjusting 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.
