CRUV INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
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 DriSteem 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 identifi cation 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-airfl ow duct with Rapid-sorb header either inside or outside
the duct. See the DriCalc Installation Guides library or contact your
representative/distributor or DriSteem for installation instructions for air
handler or vertical airfl ow applications.

WARNING
Hot surface and steam hazard
Dispersion tube, steam 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 humidifi er. This will result in unacceptable
humidifi cation system performance such as
leaking gaskets, blown water seals, erratic
water level control, and spitting condensate
from dispersion tubes.

Important:
Before marking and drilling holes in the duct
or air handler, refer to ALL pitch re quire ments
for the Rapid-sorb as sem bly you received
(see Table 21-1). The size, quan ti ty, and
location of penetrations are determined by the
dimensions and confi guration of the Rapid-sorb
assembly you received.
