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 27-1). 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:

components with packing list. Report any shortages to
DRI-STEEM immediately. The components typically include
the following:
– Multiple dispersion tubes
– Header
– 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 1270 mm long or shorter has a mounting hole
100 mm from each end for mounting the L-bracket to the
duct or air handler wall.
– L-bracket longer than 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.

t 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.
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.
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.
