Factory settings are in Bold
Air fl ow values are with dry coil and 1 in. MERV 4.
For wet coil performance fi rst calculate the face velocity of the air coil (Face Velocity [fpm] = Airfl ow [cfm] / Face Area [sq ft]).
Then for velocities of 200 fpm reduce the static capability by 0.03 in. wg, 300 fpm by 0.08 in. wg, 400 fpm by 0.12in. wg. and 500
fpm by 0.16 in. wg.
* Denotes setting for 265 V operation.
