ONNECTING THE UCTS TO THE
NOTE: This unit was designed to be connected to ducts of at least 4" in diameter, but can be connected to bigger sized ducts by using an
appropriate transition (e.g.: 4" diameter to 5" diameter transition).
Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation within
the ducts.
1. Pull back the insulation to expose the flexible duct.
2. Attach the flexible duct to the port using a tie wrap.
3. Pull the insulation over the joint and tuck it in between the inner and outer rings of the double collar.
4. Pull down the vapor barrier (shaded part in illustrations below) over the outer ring to cover it completely. Apply duct tape to the joint to
make an airtight seal. Avoid compressing the insulation when pulling the tape tightly around the joint.

ONNECTING THE RAIN
1. Connect the plastic tube to the drain fitting located under the unit.
2. Make a water trap loop in the tube to prevent the unit from drawing unpleasant odors from the
drain source. Run the tube to the floor drain or to an alternative drain pipe or pail.
If using a pail to collect water, locate the tube end approximately 1" into the pail
in order to prevent water from being drawn back up into the unit.
