Fasten the L-bracket to the end of the dispersion tubes with the
provided bolt, lock washer, and flat washer.
5. Before tightening the L-bracket bolts to the dispersion tubes
follow these instructions:
 t 'PS%/EJTQFSTJPOUVCFT
– The dispersion tube will rotate in the slip coupling. Verify
that the dispersion tube orifices are directed perpendicular
to the airflow.
– The dispersion tube and slip coupling must be fully
engaged on to the header stub for the O-rings to provide a
seal.
 t 'PS%/EJTQFSTJPOUVCFT
– Before securing the hose cuff in place with the hose clamps
on the dispersion tube and the header stub, verify that the
dispersion tube orifices are directed perpendicular to the
airflow.
6. Slide the assembly up until the L-bracket aligns with the
mounting holes in the duct.
 t 'PS%/EJTQFSTJPOUVCFT
– The header pitch is duplicated in the L-bracket.
– The dispersion tube and slip coupling must be fully
engaged on to the header stub for the O-rings to provide a
seal.
– The high end of the L-bracket can be fastened tight to the
duct or air handler.
– On the low end of the L-bracket, the fastener must be long
enough to compensate for the pitch, and a nut should be
provided and secured on both sides of the L-bracket and
the duct or air handler for stability.
 t 'PS%/EJTQFSTJPOUVCFT
– Fasten the bracket to the top of the duct and use the hose
cuffs to compensate for the pitch of the header.
– Before securing the hose cuff in place with the hose clamps
on the dispersion tube and the header stub, verify that the
header pitch, 1/8"/ft (1%) toward drain, is maintained.
7. Permanently secure both ends of the header and verify that the
header pitch, 1/8"/ft (1%) toward drain, is maintained.
8. Verify that all fasteners are secure:
