INSTALLATION IN A COLD AIR STREAM
When a steam dispersion panel 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
thermostat set to cut off the steam dispersion panel at a safe temperature can
be used for this purpose. See Figure 8-1.
PLACEMENT UPSTREAM FROM AN ELBOW OR DUCT SPLIT
Due to Ultra-sorb's rapid steam absorption performance, installation upstream
from elbows or duct splits can be done with confi dence. See Figure 8-2.
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 cause serious damage to the equipment below. When such
an installation cannot be avoided, install a galvanized 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.
Otherwise, the weight may impose stress on the connections, causing them to
fracture and leak.
