After attaching the supply tubing to the sound attenuating
tube, bring the open end of the tube to the plenum.
To cut a hole in the plenum, refer to duct installation
instructions supplied with fan coil unit. Sheet metal duct
requires a 2

" hole.
Remove the hole cut-out from the plenum. Make sure
there is no “flap” left inside plenum that could block hole
during operation.
Place the plenum take-off gasket on the back side of the
plenum take-off and insert the assembly into the hole in
the plenum (see Figure 2.25).
NOTICE: Gasket must be installed to seal plenum
take-off to prevent air leakage.
Orient the plenum take-off to match the curvature of the
plenum duct. Hand insert the four plenum take off
fasteners one at a time such that each clip reaches the
interior of the duct. Using the SpacePak pliers, snap the
fasteners into place until they lock in place (see Figure
2.26).
NOTICE: All four fasteners must be installed to
assure air tight fitting between plenum take-off and
plenum.

Supply Tubing Installation
Kwik-connects and balancing orifices are provided in the
Installation Kits. Plenum take-offs, gaskets and fasteners
are supplied in the separate plenum take-off kit.
Avoid sharp bends in the supply tubing (as well as the
sound attenuating tubing). The minimum radius bend is
4" (see Figure 2.21); however, wherever possible, hold to
a larger radius.
At the plenum, all supply tubing connections must be a
minimum of 18" from any plenum tee, plenum elbow or
the fan coil unit.
Individual supply tubing runs must be a minimum of
6-feet, even if the distance between the sound
attenuating tubing and plenum is less than 6 feet.
Supply tubing comes in 100-foot sections (R8 tubing
comes in 75-foot sections) and may be cut to length with
a knife or fine tooth hacksaw.
For each supply tubing run, estimate and cut the length
of tubing that will be needed between the plenum and
sound attenuating tube. At the open end of the supply
tubing a kwik-connect will be installed (see Figure 2.22).
First, push back the cover and the insulation exposing
approximately 4" of the inner core. Fold in any tails or
frays that may be present after cutting the supply tubing.
Second, hand compress the corrugations until they are
densely compacted 1

" to 2" from the open end of the
supply tube. Third, thread kwik-connect into the inner
core until snug. Fourth, pull the insulation and cover for-
ward and tuck it into the deep groove on the back side
of the kwik-connect. Fifth, wrap the connection securely
with UL181 approved tape.
When finished, simply twist together (see Figure 2.23)
the kwik-connect on the sound attenuating tube, and
wrap the connection securely with tape.
