ULTRA-SORB MODEL XV INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
• 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 of the heating coil where the air is
warmest.
• Do not place the Ultra-sorb panel in an outside air intake unless the air is
fi rst 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 Ultra-sorb upstream from fi lter media” on Page
28.
• Do not place the Ultra-sorb panel where discharged visible mist will
impinge directly on a metal surface.
PLACEMENT IN AN AIR HANDLING UNIT (FIGURE 6-1)
• Location A is the best choice. Installing downstream of heating and cooling
coils provides the most even fl ow through the dispersion unit; plus, the
heated air provides an environment for best absorption.
• Location B is the second-best choice. However, in change-over periods, 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 of a fan.
• Location D is the poorest choice. The cooler air at this location requires an
increased non-wetting distance.

DETERMINE STEAM DISPERSION PANEL 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.
