Notes: 1 At ARI flow rate 2 Maximum and minimum values may not
be combined. If one value is at maximum or minimum, the other two conditions may not exceed the normal condition for standard units.
Extended range units may combine any two maximum conditions, but not more than two, with all other conditions being normal conditions.

Notes: 1. n/a = ECM not available in unit sizes 007, 009, 012. 2. For wet coil, calculate face velocity (cfm/ coil face area, sq. ft.). Add the following static to the external static
pressure for the corresponding face velocity: 300 fpm = 0.05", 400 fpm = 0.10", 500 fpm = 0.14". Re-enter table at the increased external static pressure to determine final cfm.
