3.3 Uncrating and
Preparation
Immediately upon uncrating, check the electrical characteristics to verify that the unit
is suitable for the installation site.
Shipped-with and Shipped-separate Items - A carton shipped inside the unit con-
tains the vertical supply air opening cover and parts to assemble and install the inlet
and exhaust hoods. The hoods will be attached after the unit is in the installed loca-
tion.
Before beginning installation, be sure that all shipped-separate options ordered are
available at the site. Shipped-separate options could include a roof curb, a wall-
mounted control, and/or a disconnect switch.
Supply Air (Discharge) and Return Air Openings - To enable the installer to adapt
to either vertical or horizontal ductwork, the cabinet has both vertical and horizontal
supply and return air openings. Both the horizontal supply air and return air openings
are capped during shipping.
NOTE: There are no vertical duct connections on the unit; duct flange connections are
part of the roof curb. The curb is designed to slide the ductwork into the vertical duct
openings from the roof before the unit is lifted to the curb.

curb. There are no vertical
duct flanges on the unit.
The curb is designed for
ductwork to be installed
from the top before the unit
is set on the curb.
