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:
• For 1½" (DN40) dispersion tubes:
– 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.
• For 2" (DN50) dispersion tubes:
– 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.
• For 1½" (DN40) dispersion tubes:
– 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.
• For 2" (DN50) dispersion tubes:
– 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:
• L-bracket to duct
• Dispersion tubes to L-bracket
• Hose clamps on 2" (DN50) tubes
9. Secure and seal the dispersion tube escutcheon plate and
condensate drain tube escutcheon plate around the respective
tubes, if applicable.
