Rapid-Sorb; Horizontal Duct Installation - VAPORSTREAM VLC Installation Instructions And Maintenance Operations Manual

RAPID-SORB

Instructions for Horizontal Duct
1. Unpack shipment and verify receipt of all
RAPID-SORB components with packing list. Report
any shortages to the DRI-STEEM factory immediately.
2. Provide necessary access in and around duct work.
3. Locate stainless steel channel inside the duct. Hang
the channel from the top of the duct, centered between
duct side walls, with the two mounting holes provided.
4. If hose cuffs are used, slide cuffs over the open end
of each tube. Install a pair of hose clamps on each
tube.
5. Note direction of air flow within duct, then arrange
each dispersion tube so steam will discharge perpen-
dicular to the air flow. Use hex bolts and nuts to attach
tubes to overhead channel. Do not secure. If the
header is under the duct (see figure 11-2), punch-out
necessary clearance holes in the base of the duct to
slide dispersion tubes up from bottom.
6. For a Header Inside the Duct (See figure 11-1):
Punch or cut out necessary clearance holes for
RAPID-SORB header. Slide header into the duct,
position header and slide the dispersion tube hose
cuffs or slip couplings over the header dispersion tube
nipples.
Position the header so vertical dispersion tubes are
perpendicular to duct and pitch the header to conden-
sate drain. Secure header mounting bracket to the
ductwork. Use escutcheon plates to secure header
where it enters the duct.

Check that the dispersion tubes discharge steam
perpendicular to the air flow. Secure tubes to the
overhead channel. Secure the channel to the duct.
Position hose cuffs or slip couplings over tube and
header tube nipples, and secure with clamps.
For a Header Under the Duct (See figure 11-2):
Position header under dispersion tubes, then slide hose
cuffs or slip couplings over header dispersion tube
nipples.
Position the header so dispersion tubes are perpen-
dicular to duct and pitch the header to condensate
drain. Secure header mounting bracket to a support
strap. Secure dispersion tubes in place with the tube
escutcheon plates provided.
Check the position of the tubes for steam release
perpendicular to the air flow. Secure tubes to the
overhead channel, and secure channel to the duct.
With header pitched to condensate drain, slip hose
cuffs or slip couplings over tube nipples and secure
with clamps.
7. Connect a condensate drain to the header, provide
the water trap as shown, and run to open drain, sized
according to local codes.
8. Attach the header steam supply connector to main
header using the hose cuff and clamps provided, but do
not secure.
9. Route the necessary number of vapor hoses or
pipes from the humidifier tank, position connector to
accept the hoses or pipes and secure.
Note: Refer to page 15 for vapor hose information on
routing and for alternate vapor hose installation
methods.
