Removing uninsulated tubes
Note:
The photos below depict Ultra-sorb Model LV (vertical
tubes). The supply header is on the top, and the condensate
header is on the bottom. If retrofitting an Ultra-sorb Model
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 retrofitting an existing Ultra-sorb panel with high-efficiency
tubes, 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 high-efficiency 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 20-2.

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.
