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

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 1" x 1½" (25 mm x 38 mm) 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 perpendicular to
the air flow. Use the hex bolts provided to attach tubes to
overhead 1" x 1½" (25 mm x 38 mm) channel. Do not
secure. If the header is outside the duct (see figure 13-2),
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 13-1.):
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 condensate
drain. Secure header to the mounting bracket. Use
escutcheon plates to secure header where it enters the
duct.

Check that the dispersion tubes discharge steam perpen-
dicular 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 Outside the Duct (See figure 13-2.):
Position header under dispersion tubes, then slide hose
cuffs or slip couplings over header dispersion tube nipples.
Position the header so dispersion tubes are perpendicular
to duct and pitch the header to condensate drain. Secure
dispersion tubes in place with the tube escutcheon plates
provided.
Check the position of the tubes for steam release perpen-
dicular 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 accord-
ing 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.
