INSTALLATION
INSTALLATION IN A COLD AIR STREAM
When a humidifier 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 12-1.
PLACEMENT UPSTREAM FROM AN ELBOW OR DUCT SPLIT
Installation upstream from elbows or duct splits can be done. See Figure
12-2 if placed upstream a minimum of the non-wetting distance. Ensure
adequate absorption prior to a duct transition to prevent potential wetting of
duct surfaces. Place transition at least the non-wetting distance downstream but
may be longer.
INSTALLATION ABOVE VALUABLE EQUIPMENT
Water piping and humidifiers 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 humidifier piping, valve, etc. to catch
and drain away unintended water. See Figure 12-3.
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.
