Unpacking High-efficiency tubes
CAUTION!
The High-efficiency 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.
NOTE: If you have an Ultra-sorb without High-efficiency
dispersion tubes (non-insulated tubes), please skip to the next
page.
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 High-efficiency 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.
• 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.
High-efficiency Tube option
Ultra-sorb dispersion assemblies with the
High-efficiency Tube option are designed to
produce significantly less dispersion-generated
condensate and airstream heat gain, which
reduces wasted energy by up to 85%. These
improvements are accomplished by reducing
the thermal conductivity of the tubes with
1/8" of polyvinylidene fluoride (PVDF)
insulating material on the outside of the tubes.
These assemblies require careful unpacking,
installation, and handling. If your dispersion
assembly has the High-efficiency Tube option,
be sure to read this section carefully.

Please read instructions while assembling
STEP 1 - Unpack
Unpack the Ultra-sorb components and verify that you have all
items on the packing list.
Note that both the supply header assembly and the condensate
header assembly have a ¾" half coupling drain connection on one
end. This will be the lower end of the installed dispersion assembly.
The supply header assembly has a steam inlet (nipple or tubing) on
the end opposite the drain connection.
Arrange the components on a large, flat working surface,
positioning them as indicated in Figure 4-1 (condensate header to
the left, supply header to the right).

STEP 2 - Bolt the mounting flanges to the supply header
assembly
Refer to Figure 5-1 and 5-2.
Attach the two mounting flanges to the supply header assembly as
indicated using ¼" - 20 bolts with the nuts finger tight.
STEP 3 - Insert the dispersion tubes
Refer to Figure 5-3. Insert the plain ends (no slip couplings)
of the dispersion tubes into the slip couplings already mounted
on the supply header assembly. The slip couplings are factory
lubricated; if well aligned during insertion, no further lubrication
should be needed. Push and twist the tube in until it bottoms out
on the internal shoulder of the slip coupling (see Figure 5-4).
CAUTION! Use care to avoid cutting the internal O-rings of the
slip couplings.

STEP 4 - Bolt the mounting flanges to the condensate header
assembly
Refer to Figure 6-1. Push the slip couplings onto the dispersion
tubes flush with the tube ends. Make sure the drain connection is
properly oriented. Attach the mounting flanges using ¼" - 20 bolts,
and leave the nuts finger tight.
STEP 5 - Slide the slip couplings onto the condensate header as-
sembly and orient the tubelets
SUGGESTION: Gripping the drain connection with vise grip pliers
and applying a back and forth rolling motion to the header will
assist in sliding the slip couplings into place.
Refer to Figure 6-2. It may be necessary to push and twist the
slip couplings onto the condensate header. Again care must be
taken to avoid cutting the internal O-rings. Slide the slip couplings
on until they bottom out against the stop disc on the condensate
header. The steam tubelets must be aimed so that they discharge the
steam perpendicular to the airstream. Rotate the dispersion tubes as
needed.
After tightening the ¼" - 20 bolts at all 4 corners, the Ultra-sorb
panel is ready for installation. See page 10.

Selecting the location
Ultra-sorb steam dispersion panels need a steam supply and a
method for trapping and removing condensate. See supply and
drain connections information on Page 16.
When selecting the location, first consideration should be given to
rapid, thorough absorption of the steam. The warmest air will most
readily absorb the steam.
The distance that unabsorbed steam will travel within a given
airstream has been cataloged by DRI-STEEM. See Figure 22-2.
A. You must install the Ultra-sorb panel in a location where the
water vapor being discharged will be absorbed by the airstream.
B. In general, place the Ultra-sorb panel where the air temperature
is capable of absorbing steam being discharged without
causing condensation at or after the unit. This will normally be
downstream of the heating coil or where the air temperature is
warmest.
C. Do not place the Ultra-sorb panel in an outside air intake unless
the air is tempered with a preheat coil.
D. Do not place the Ultra-sorb panel too near to the entrance of a
high-efficiency filter. The filter will remove the visible moisture
and become waterlogged. See Note 3 on page 22 for absorption
(non-wetting) distance.
E. Do not place the Ultra-sorb panel where discharged visible mist
will impinge directly on a metal surface.
Note: To prevent leakage, use HVAC caulking or a similar weather
sealant to seal all places where the Ultra-sorb installation hardware
and ttings penetrate the wall of the duct.
