• Rotate the slip coupling as you push it on to the tubing.
• The O-rings are lubricated at the factory. If additional
lubrication is necessary, DO NOT use a petroleum-based
lubricant.
5. Allow the dispersion tubes to rest against the bottom of the duct.
6. Position the flange of the L-bracket so it is upstream of the tubes
when the assembly is rotated into position. Fasten the L-bracket
to the end of the dispersion tubes with the provided bolt, lock
washer, and flat washer.
7. Rotate the assembly up until the L-bracket aligns with the
mounting holes in the duct or air handler.
• 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.
• 2" (DN50) dispersion tubes
– Fasten the bracket to the top of the duct or air handler 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
dispersion tube orifices are directed perpendicular to the
airflow.
8. Verify that all fasteners are secure:
• L-bracket to duct
• Dispersion tubes to L-bracket
• Hose clamps on 2" (DN50) tubes
• Header support bracket fastener
9. Secure and seal the header escutcheon plate around the header.
