TIP: Honeywell recommends using approximately 16 inches of flexible duct (supplied in kit with VNT5150,
VNT5200, VNT6150 and VNT6200) between the 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.
TIP: For the VNT5070 unit, balancing should be done
before taping the insulation onto the collar. See
balancing steps on page 30.
4b. Attach collar onto unit (VNT5070)
IMPORTANT:

This step is critical in order to prevent
condensation accumulation.

collar.

VNT6150 and VNT6200)

attach the collar to the unit.
