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.

Field assembly of Model LH

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.

Page 10 • DRI-STEEM Ultra-sorb Steam Dispersion Panel Installation, Operation, and Maintenance Manual

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.
