VAPORMIST INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Dispersion:
INSTALLATION
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 31-1). The size, quantity, and
location of penetrations are determined by the
dimensions and configuration of the Rapid-sorb
assembly you received.

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
– 3/4" × 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 DriCalc Installation Guides library or contact your
representative/distributor or DriSteem for installation instructions for air
handler or vertical airflow applications.

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 dispersion tubes.

WARNING
Hot surface and steam hazard
Dispersion tube, steam hose, or tubing
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.
