INSTALLATION
Note:
See Page 36 for steam supply and condensate
drain line connection instructions.
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 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.
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 orifices are directed
perpendicular to airflow.
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.
