Main Duct with Duct Extension
6. In the room where the main duct kit is attached to the
chassis, cut a hole in the wall at the same height from the
floor that the main duct is located. Cut the hole 1/8”
larger than the width and height (10” x 5”) dimensions of
the extension duct (Figure 16).

7. Measure from the end of the main duct where the
extension duct will be connected to the hole in the wall.
If necessary cut the extension duct to a length where the
cut end protrudes into the wall’s inner space and one
inch from the adjoining room’s wall surface.
8. Insert the extension duct into the opening in the wall.
Install the extension duct by placing the slotted flange
over the two screws in the main duct. Using two #8 round
Phillips head screws, mount bottom of extension duct to
mounting bracket through the bracket slot (Figure 14).
NOTE: The EDK02 can be cut into two sections and used
with two MDK02s if the needed length does not exceed
21-1/4”.
Terminal Duct Kit (TDK02) Installation
The sheet metal collar of the terminal duct kit must be
mounted in the wall of the adjoining room opposite the room
where the main duct kit is attached to the PTAC chassis.
1. Cut a hole in the wall of the adjoining room such that the
hole is centered on the extension duct that is currently
in the wall of the opposite room. See Figure 17 for proper
wall hole dimensions for sheet metal collar.

2. Insert the sheet metal collar into the wall so that the
flanges will mount flush to the wall after the collar is
pushed all the way into the wall. While pushing the collar
into the wall make sure the extension duct is inside the
collar. Use four #8 screws to attach metal collar to wall
(Figure 18).
