Integrated Drain Pump
Air is returned through the center of the grille, while evenly
distributing air through each of the 4 supply air openings.
Installation in the center of the room provides for the greatest
comfort. However, 1 or 2 supply louvers can be closed for
installation near 1 wall to provide 3 or 2 way airflow. Also,
by closing off 1 supply louver,
you may attach a duct (field
supply) to the upper plenum and
provide conditioned air to another,
separate area.
