Unpacking High-Effi ciency Tubes

UNPACKING HIGH-EFFICIENCY TUBES

NOTE: If you have an Ultra-sorb without High-effi ciency dispersion tubes (non­insulated tubes), please skip to the next page.

UNPACKING

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

• Some dispersion panels are shipped unassembled. Do not lay High­Effi ciency Tubes across or under anything that could compress or damage
the insulating material. Compressed insulating material has a reduced
R-value.

• Before start-up, remove the clear poly fi lm covering the insulation by tearing
it along the perforation. Do not use a knife or sharp object to remove the

poly fi lm.

CAUTION

Remove clear poly fi lm; do not remove white PVDF insulation.

High-effi ciency tubes are sleeved in clear poly fi lm for
protection during, shipping, and installation. Leave the clear
poly fi lm on until installation is complete.

Remove and discard the clear poly fi lm before start-up by
tearing it along the perforations. Do not remove the white

PVDF insulation.

• Keep fl ame away from the insulation to avoid damage.

• PVDF is resistant to UV light. UV-C light from
germicidal lamps will not cause the insulating
material to degrade.

• Do not tighten mounting clamps or fasteners to any part of the dispersion tube.

High-efficiency tube option

Dispersion assemblies with the High-Effi ciency
Tube option are designed to produce
signifi cantly less dispersion-generated
condensate and airstream heat gain, which
reduces wasted energy by up to 85%.

INSTALLATION

Ultra-sorb Model MP fi eld assembly

Note: These assembly instructions are for Ultra-sorb Model MP panels shipped

unassembled by request or as required. Panels with overall height more
than 98" (2490 mm) are shipped unassembled.

LAY OUT THE PANEL COMPONENTS

Place the panel components on a large, fl at working surface.

ATTACH THE TOP FRAME ASSEMBLY

Span the fl anges with the top frame assembly. Align the locating pins on the
fl anges and top frame, and insert screws.

TIGHTEN THE FLANGE LOCKNUTS

Torque the eight fl ange locknuts to 16 ft-lb (22 N-m) at 100 rpm maximum
using a 7/16" deep-well socket.

INSTALL THE DISPERSION TUBES

Note: Do not remove the poly fi lm from the dispersion tubes until after the

panel is installed.

Ultra-sorb Model MP fi eld assembly

INSERT DISPERSION TUBES INTO AN UNASSEMBLED ULTRA-SORB PANEL

If the Ultra-sorb Model MP panel was shipped unassembled, the dispersion
tubes need to be inserted into the panel.

Note: Use soapy water to lubricate end of tubes where inserted into rubber
grommet.

1. Insert tube into rubber grommet at panel header, with open end at bottom.
Insert at a slight angle to not interfere with top frame of Ultra-sorb panel.

2. Press downward on tube so to clear stud at top of tube. Align tube with
rivet nut on top of the header.

3. Once aligned, turn the tube three full rotations into rivet nut for proper
engagement.

4. Turn the tube backwards so that the steam tubelets face the next tube,
perpendicular to air flow. Face the lowest tubelet of each tube in the same
direction so the facing tubelets are at staggered heights.

INSTALLATION

5. Tighten the locknut down to the top header to 10 in-lbs (1.13 N-m).
Note: If the rivet nut pulls through, add a ¼"-20 nut on each side of the
top flange to secure the tube.

INSTALLATION

Selecting the location

DETERMINE HUMIDIFIER PLACEMENT

Dispersed steam must be absorbed into the airfl ow before it comes in
contact with duct elbows, fans, vanes, fi lters, or any object that can cause
condensation and dripping.

• Install the Ultra-sorb panel in a location where discharged water vapor will
be absorbed by the airstream.

• Place the Ultra-sorb panel where the air temperature is capable of
absorbing discharged steam without causing condensation at or after the
unit. This will normally be downstream from the heating coil where the air is
warmest.

• Do not place the Ultra-sorb panel in an outside air intake unless the air is
tempered with a preheat coil.

• Do not place the Ultra-sorb panel near the entrance of a high-effi ciency
fi lter. The fi lter will remove visible moisture and become waterlogged. See
the Caution "Installing the Ultra-sorb panel upstream from fi lter media" on
page 21.

• Do not place the Ultra-sorb panel where discharged visible mist will
impinge directly on a metal surface.

mc_071111_1710

PLACEMENT IN AN AIR HANDLING UNIT

• Location A is the best choice. Installing downstream from heating and
cooling coils provides laminar fl ow through the dispersion unit; plus, the
heated air provides an environment for best absorption.

• Location B is the second-best choice. However, conditions when both
cooling and humidifi cation is needed, the cooling coil will eliminate some
moisture for humidifi cation.

• Location C is the third-best choice. Air leaving a fan is usually very turbulent
and can cause vapor to not absorb at the expected non-wetting distance.
Allow for more distance if installing downstream from a fan.

• Location D is the poorest choice. The cooler air at this location requires an
increased non-wetting distance.

INSTALLATION

Mounting and support

INSTALLATION IN A COLD AIR STREAM

When a humidifi er is installed in a duct that will carry cold air, determine
the dew point temperature. If the psychrometric chart reveals that saturation
may occur, protection should be provided. A high-limit humidistat or humidity
transmitter can be used for this purpose. See Figure 8-1.

PLACEMENT UPSTREAM FROM AN ELBOW OR DUCT SPLIT

Installation upstream from elbows or duct splits can be done. See Figure
8-2 if placed upstream a minimum of the non-wetting distance.

INSTALLATION ABOVE VALUABLE EQUIPMENT

Water piping and humidifi ers should not be installed above expensive
equipment. A condensing or leaking water pipe or other accidental water
spillage could damage the equipment below. When such an installation cannot
be avoided, install a drip pan under the humidifi er piping, valve, etc. to catch
and drain away unintended water. See Figure 8-3.

PANEL SUPPORT

The duct or air handler section and Ultra-sorb panel must be properly
supported to carry the weight of the assembly. The weight of the piping must
be supported by the building structure rather than by the Ultra-sorb unit.
Excessive weight on the Ultra-sorb panel may stress the connections, causing
them to fracture and leak.
