Airflow
Position L-bracket so that flange is upstream
of dispersion tubes. Drawing shows L-bracket
positioned for airflow back to front.
Dispersion tube
Point tubelets perpendicular to airflow
Slip coupling or hose cuff
WARNING!
Dispersion tube, vapor hose, tubing, or hard
pipe can contain steam, and surfaces can be
hot. Discharged steam is not visible. Contact
with hot surfaces or air into which steam has
been discharged can cause severe personal
injury.
Assembly and installation instructions for a Rapid-sorb installed
with header outside the duct (horizontal airflow)
1. Locate and cut the holes in the ductwork for the dispersion
tubes. Use the L-bracket as a template to locate the holes on the
duct floor.
2. Temporarily, loosely suspend or support the header below the
final location — the vertical balance point of the dispersion
tube length dictates where the header should be suspended or
supported temporarily.
3. Mount the dispersion tubes to the header with the provided
connector, either a slip coupling or a hose cuff.

lubrication is necessary, DO NOT use a petroleum-based
lubricant.
4. Position the flange of the L-bracket so it is upstream of the
tubes when the assembly is raised and fastened into position.
Pitch
(see Note 1)
Notes:
1 Pitch vapor hose, tubing,
or pipe toward Rapid-sorb:
– 2"/ft (15%) when
using vapor hose
– 1/8"/ft (1%) when
using tubing or pipe
2 Use DRI-STEEM’s hard pipe
adapter kit to connect the steam outlet to hard
pipe. Use a hose clamp to connect the steam
outlet to vapor hose. Use a hose cuff and clamps
to connect the steam outlet to tubing.
Open drain required.
Locate air gap only in spaces with adequate temperature and air
movement to absorb flash steam; otherwise, condensation may
form on nearby surfaces. Refer to governing codes for drain pipe
size and maximum discharge water temperature.
Vapor hose, tubing or
pipe. Insulate tubing and
hard pipe to reduce steam
loss. Do not insulate vapor
hose. See Table 16-1 for
maximum piping lengths.
