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.
