Installation
4. Mount the dispersion tubes on the header with the slip
couplings or hose cuffs:
• When installing slip couplings for 1½" (DN40) dispersion
tubes, take care not to shear O-rings.
• Set slip coupling on header stub or dispersion tube so O-ring
is resting on face of tubing.
• Rotate slip coupling while pushing it onto the tubing.
• O-rings are lubricated at factory. If additional lubrication is
necessary, DO NOT use 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.
• 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.
• 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 dispersion
tube orifices are directed perpendicular to 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.
