Installation
Dispersion:
Rapid-sorb
Read all dispersion instructions in this manual, and follow the
installation instructions below:
• Unpack shipment and verify receipt of all Rapid-sorb
components with packing list. Report any shortages to
DRI-STEEM immediately. The components typically include
the following:
– Multiple dispersion tubes
– Header
– ¾" × 2" (19 mm × 51 mm) L-bracket
Note: Dispersion tubes, header, and L-bracket are each
tagged with the customer requested identification
number.
– A single duct escutcheon plate the size of the header
– Slip couplings or hose cuffs and clamps
– Accessories such as duct plates, slip couplings, or hose cuffs
– Bolts and washers for mounting the dispersion tubes to the
bracket
• L-bracket mounting holes (see note at left):
– L-bracket 50" (1270 mm) long or shorter has a mounting
hole 4" (100 mm) from each end for mounting the L-bracket
to the duct or air handler wall.
– L-bracket longer than 50" (1270 mm) has an additional
mounting hole in the center.
Note: Hardware for mounting the L-bracket to the duct or air
handler wall and the hardware for the header support
bracket is not provided.
• Select an installation location that provides necessary access in
and around the ductwork or air handler.
• The Rapid-sorb typically is installed centered side to side in a
duct, or is installed across the face of a coil in an air handler.
• The center line of the outer dispersion tubes should never be
closer than 4.5" (114 mm) from the side of the ductwork or air
handler wall.
• The following instructions are for a typical Rapid-sorb
installation — horizontal-airflow duct with Rapid-sorb header
either inside or outside the duct. See the Dri-calc Installation
Guides library or contact your representative/distributor or
DRI-STEEM for installation instructions for air handler or
vertical airflow applications.

WARNING
Hot surface and steam hazard
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.

Important:
Failure to follow the recommendations in this
section can result in excessive back pressure on
the humidifier. This will result in unacceptable
humidification system performance such as
leaking gaskets, blown water seals, erratic water
level control, and spitting condensate from the
dispersion tube.

Important:
Before marking and drilling holes in the duct
or air handler, refer to ALL pitch requirements
for the Rapid-sorb assembly you received (see
Table 21-1). The size, quantity, and location of
penetrations are determined by the dimensions
and configuration of the Rapid-sorb assembly
you received.
