Installation
Dispersion: 
Rapid-sorb
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.
