RAPID-SORB
®
ASSEMBLY AND INSTALLATION
Horizontal Duct Installation
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" stainless steel channel inside the
duct. Hang the channel from the top of the duct, cen-
tered 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 blow perpendicular to
the air flow. Use the hex bolts provided to attach tubes
to overhead 1" x 1½" channel. Do not secure. If the
header is outside the duct punch-out necessary clear-
ance holes in the base of the duct to slide dispersion
tubes up from bottom.
For a Header Inside the Duct (See figure 19-1):
6. 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.
7. 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.
8. Check that the dispersion tubes release 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.
For a Header Outside the Duct (See figure 19-2):
6. Position header under dispersion tubes, then slide
hose cuffs or slip couplings over header dispersion tube
nipples.
7. Position the header so dispersion tubes are perpen-
dicular to duct and pitch the header to condensate drain.
Secure dispersion tubes in place with the tube escutch-
eon plates provided.
8. Check the position of the tubes for steam release
perpendicular to the air flow. Secure tubes to the over-
head channel, and secure channel to the duct. With
header pitched to condensate drain, slip hose cuffs or
slip couplings over tube nipples and secure.
9. Connect a condensate drain to the header, provide the
water trap as shown, and run to open drain, sized
according to governing codes.
10. Attach the header steam supply connector to main
header using the hose cuff and clamps provided, but do
not secure.
11. 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 18 for vapor hose information on
routing and for alternate vapor hose installation methods.
