Unpacking and installation

UNPACKING

• Remove the dispersion assembly from the shipping container; be careful
not to bump or scrape the PVDF insulating material on the dispersion
tubes.

• Some dispersion panels are shipped unassembled by customer request or
by shipping necessity. Do not lay loose insulated dispersion tubes across
or under anything that could compress or damage the insulating material.
Compressed insulating material has a reduced R-value.

• Avoid bumping or snagging the PVDF insulating material. Although PVDF
is robust, rough handling can cause tears, which could negatively impact
performance.

RAPID-SORB INSTALLATION

See the unpacking instructions above and the Rapid-sorb section of your
specific humidifier manual.

After installation and before start-up, remove the clear poly film by tearing it
along the perforation. Do not use a knife or sharp object to remove the poly

film.

ULTRA-SORB INSTALLATION

See the unpacking instructions above and the Ultra-sorb manual shipped
with your dispersion assembly.

After installation and before start-up, remove the clear poly film by tearing it
along the perforation. Do not use a knife or sharp object to remove the poly

film.

CAUTION

The insulated dispersion tubes are sleeved in clear poly film for
protection during processing, shipping, and installation.

To prevent dirty insulating material, leave the clear poly film on until
installation is complete.

Equally important, remove and discard the clear poly film before
start-up by tearing it along the perforations.

Do NOT remove it.

WARNING

Steam humidification systems have
extremely hot surfaces.

To avoid burns, allow humidifier, steam
pipes, and dispersion assembly to cool
before touching any part of the system.

Before you begin, shut off steam to the system, and let all hot surfaces cool.
See the Warning below.

Note: Replacement slip couplings with internal O-rings are shipped with

retrofit insulated tube orders. There are two types of slip couplings:
with shoulders and without. Slip couplings with shoulders must go on
the supply header end of the dispersion tube. See Figure 2-2.

Note: The photos below depict Ultra-sorb LV (vertical tubes). The supply

header is on the top, and the condensate header is on the bottom.
If retrofitting an Ultra-sorb LH (horizontal tubes), pay attention to the
location of the supply and condensate headers.

Perform the following steps for each uninsulated tube being removed:

1. With a pulling and twisting motion,

slide the slip coupling off the
condensate header far enough to
reveal the end of the dispersion tube.

2. Swing the dispersion tube away
from the condensate header; pull the
