1. Mark and cut holes in the ductwork for the dispersion tubes. Use
the L-bracket as a template to mark the holes on the duct floor.
2. Temporarily, loosely suspend or support the header below
the final location. Vertical balance point of the dispersion
tube length dictates where the header should be suspended or
temporarily supported.
3. Mount the dispersion tubes to the header with the slip coupling
or hose cuff (provided).
• When installing slip couplings for 1½" (DN40) dispersion
tubes, take care not to shear the O-rings.
• Set the slip coupling on the header stub or dispersion tube so
the O-ring is resting on the face of the tubing.
• Rotate the slip coupling as you push it onto the tubing.
• The O-rings are lubricated at the factory. If additional
lubrication is necessary, DO NOT use a petroleum-based
lubricant.

Pitch (see Note 1)
Notes:
1 Pitch steam hose, tubing, or pipe toward Rapid-sorb:
– 2"/ft (15%) when using steam hose
– 1/8"/ft (1%) when using tubing or pipe
2 Use DRI-STEEM’s hard pipe adapter kit to connect steam outlet to hard pipe. Use a hose clamp to
connect steam outlet to steam hose. Use a hose cuff and clamps to connect 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.
Steam hose, tubing, or pipe
(tubing or pipe must be
grounded). Insulate tubing
and hard pipe to reduce
steam loss. Do not insulate
steam hose. See Table 24-1 for
maximum piping lengths.
