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.

• 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 on to the tubing.

• The O-rings are lubricated at the factory. If additional

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.

Fasten the L-bracket to the end of the dispersion tubes with the

provided bolt, lock washer, and flat washer.

Open drain required.

Locate air gap only in spaces with adequate

temperature and air movement to absorb ﬂash

steam, or condensing on nearby surfaces may

occur. Refer to governing codes for drain pipe

size and maximum discharge water temperature.

Point tubelets (steam oriﬁces)

perpendicular to airﬂow

Note:

* 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
