line connection instructions.
4. Position the flange of the L-bracket so it is upstream of the
tubes when the assembly is raised and fastened into position.
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:
• For 1½" (DN40) dispersion tubes:
– Dispersion tube will rotate in slip coupling. Verify that
dispersion tube orifices are directed perpendicular to
airflow.
– Dispersion tube and slip coupling must be fully engaged
on header stub for O-rings to provide a seal.
• For 2" (DN50) dispersion tubes:
Before securing hose cuff in place with hose clamps on
dispersion tube and the header stub, verify that dispersion
tube orifices are directed perpendicular to airflow.
6. Slide the assembly up until the L-bracket aligns with the
mounting holes in the duct.
• For 1½" (DN40) dispersion tubes:
– Header pitch is duplicated in the L-bracket.
– Dispersion tube and slip coupling must be fully engaged
on header stub for O-rings to provide a seal.
– High end of L-bracket can be fastened tight to duct or air
handler.
– Fastener on low end of L-bracket must be long enough
to compensate for pitch. Use a nut on both sides of
L-bracket and duct or air handler for stability.
• For 2" (DN50) dispersion tubes:
– Fasten bracket to top of duct and use hose cuffs to
compensate for header pitch.
– Before securing hose cuffs with hose clamps on
dispersion tube and header stub, verify that header pitch,
1/8"/ft (1%) toward drain, is maintained.
7. Permanently secure both ends of header, and verify that 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.
