* The net capacity data has fan motor heat factored in for all ratings and
the entering air condition of 72°F (22.2°C) and 50% RH is the standard
rating for ASHRAE 127-2001. All capacities are nominal values; actual
performance will be ±5%.
** Data rated with 2" 20% ASHRAE filter. Some options or combinations
of options may result in reduced airflow. Consult factory for
recommendations.
