NOTICE: All four fasteners must be installed to
assure air tight fitting between plenum take-off and
plenum.
In accordance with your calculations as to requirements
for balancing orifices, mount the orifice in the outlet of
the plenum take-off (see Figure 2.27), prior to attaching
the supply tubing.
Next, install a kwik-connect in the open end of the supply
tubing, using the same procedures as before, and twist
together kwik-connects on supply tubing and plenum
take-off. Wrap connection securely with tape.
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 and using the SpacePak pliers,
snap the fasteners into place until they lock in place (see
Figure 2.26).
