REMOVING UNINSULATED TUBES
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
dispersion tube and slip coupling off
the supply header.
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.

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.
