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 25 mm x 40 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 perpen-
dicular to the air flow. Use the hex bolts provided to
attach tubes to overhead 25 mm x 40 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, posi-
tion 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
perpendicular to the air flow. Secure tubes to the over-
head 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 perpendic-
ular to duct and pitch the header to condensate drain.
Secure dispersion tubes in place with the tube escutch-
eon plates provided.
Check the position of the tubes for steam release per-
pendicular 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 cou-
plings 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
