Duct
HUMIDIFIER
When selecting a location for the humidifi er, consider the following:
•
Proximity to the duct
Install the humidifi er near the air duct system where the dispersion assembly
will be located. The maximum recommended length for steam hose
connecting a single humidifi er to a dispersion assembly is 10' (3 m). The
maximum recommended developed length for tubing or pipe connecting a
single humidifi er to a dispersion assembly is 20' (6 m).
For more information about installing dispersion assemblies, see
“Dispersion,” beginning on Page 14.
• Elevation of the installed dispersion assembly
The recommended installation location for the dispersion assembly is at an
elevation higher than the humidifi er. However, if the dispersion assembly
must be installed at an elevation lower than the humidifi er, install a drip tee
and drain. See “Drip tee installation” on Page 15.
Before installing a dispersion assembly or interconnecting piping, review all
pitch requirements in the “Dispersion” section of this manual.
•
Required clearances
(see Figure 5-1)
•
Electrical connections
Electrical power supply connections are at the lower or upper right rear
corner of the unit. See “Wiring” on Page 12.
•
Supply water and drain piping connections
Water supply piping and drain connections are at the lower left rear corner
of the unit. See the piping illustrations and instructions starting on Page 8.
• Exterior wall insulation
Install the humidifi er on an exterior wall only if the wall is properly
insulated.
