Filter Installation

Each unit ships with 2-in. (5.1-cm) permanent filters (mist
eliminators) installed in the air inlet hood. The quantity of
filters is determined by unit size. Access to the filters is
through the hinged filter access panel on the air intake
hood. In addition to the filters in the intake hood, there is
a separate bank of filters accessible through the
evaporator coil compartment door. Filter type, size, and
quantity are determined by selected filter option and unit
size.
Note: Do not operate the unit without filters.
