Use the following procedure for connecting the insulated flexible ducts to the 5'' to 6'' oval ports of the unit ( EXHAUST AIR TO OUTSIDE
and FRESH AIR FROM OUTSIDE ).
1. Pull back the insulation to expose the flexible duct.
2. Connect the interior flexible duct to the smaller part of the port (5'' oval) using a
24'' tie wrap.
NOTE: If you are using a 6'' diameter insulated duct, use the bigger part of the
port (6'' oval).
3. Pull the insulation over the joint and tuck it between the inner and outer rings of the port.
Pull the vapor barrier over the insulation and over the outer ring of the port.
4. Apply duct tape gently to the joint in order to make an airtight seal.
5. Repeat steps 1 to 4 for all insulated ducts.
Avoid compressing the insulation when you pull the tape tightly around the joint. Compressed insulation loses its insulation
properties and causes water dripping due to condensation on the exterior surface of the duct.
See figure beside to find the EXHAUST AIR TO OUTSIDE (1)
and FRESH AIR FROM OUTSIDE (2) oval ports on the top of the unit.
Be careful to connect the right insulated duct to its corresponding port.
