air entering the system. Closed, it provides a leakproof seal
which prevents ambient air from seeping in or conditioned air
from seeping out. It can be adjusted easily for 100% outdoor
air or any proportions of mixed air. Like the base unit, the economizer
is converted easily for horizontal discharge applications.
