ONNECTING THE DUCTS TO THE
I
NSULATED FLEXIBLE DUCTS
NOTE: When using flexible ducts, the complete duct run must be accessible and kept as short as possible.
Use the following procedure for connecting the insulated flexible duct to the ports on the unit (exhaust to outside and fresh air from
outside).

Pull back the insulation to expose the flexible duct and place it over inner port ring.

Install good quality aluminum duct tape on flexible duct to prevent potential water leakage from duct.

Attach the flexible duct to the port using tie wrap.

Pull the insulation over the joint and tuck it between the inner and outer rings of the double collar.
 
Pull down the vapor barrier (shaded part in illustrations below) over the outer ring to cover it completely. Fasten in place the vapor
barrier using the port strap (included in unit parts bag). To do so, insert one collar pin through vapor barrier and first strap hole,
then insert the other collar pin through vapor barrier and center strap hole and close the loop by inserting the first collar pin in the
last strap hole.
Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation within
the ducts.

NOTE: Rigid ducts connected to the cold side of the unit must have a minimum insulation of R4.
To prevent potential water leakage from ducts, use good quality aluminum duct tape to connect the rigid ducts to the ports.
Do not use screws to connect rigid ducts to the ports.
Make sure that both balancing dampers are left in a fully
open position before connecting the ducts to Fresh air to
building port and Exhaust air from building port (as
shown in illustration at right).
