CRUV INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
INSTALLATION
5. 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 dis per sion 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.
6. Allow the dispersion tubes to rest against the bottom of the duct.
7. 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.
8. 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 orifi ces are directed
perpendicular to airfl ow.
9. 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
10. Secure and seal the header escutcheon plate around the header.
