unit and the rigid duct for noise dampening. The flex duct is mounted to the unit the same way as the
insulated flex.
1. Insert the vinyl duct over the hooks on the
duct collar and seal with a supplied 30 inch
tie wrap.
3. Finish by taping the duct on the collar.
5. Secure collar with the supplied 5/8 in.
hex-head screws.

2. Insert insulation inside the outer ring of the duct
collar.
4. Slide collar onto unit.
IMPORTANT: Always fix and secure each collar using
four of the 5/8 in. screws supplied.
This step is critical in order to prevent
condensation accumulation.
TIP: Attach the flex duct to the collar first, and then
attach the collar to the unit.
