1. Due to alternate sheaves, 'Turns Open' may vary within ±0.5 turn from
the position shown above.
2. Units factory shipped with standard static sheave and drive at 2.5
turns open (5200 cfm at 0.4 in. wg ESP Wet Coil). Other speeds
require field selection.

3. ISO/ARI rating point with standard static sheave and drive at 2 turns
open (5200 cfm at 0.48 in. wg ESP Wet Coil). Other speeds require
field selection.
4. For applications requiring higher static pressures, contact your local
representative.
5. Performance data does not include drive losses and is based on sea
level conditions.
6. Do not operate in gray region.
7. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e.,
208 v for 208-230-v units.
8. For wet coil performance first calculate the face velocity of the air coil
(Face Velocity [fpm] = Airflow [cfm]/Face Area [sq ft]). Then for veloci-
ties of 200 fpm reduce the static capability by 0.03 in. wg, 300 fpm by
0.08 in. wg, 400 fpm by 0.12 in. wg and 500 fpm by 0.16 in. wg.
