Humidifier
When selecting a location for the humidifier, consider the
following:
• Proximity to the duct
Install the humidifier near the air duct system where
the dispersion assembly will be located. The maximum
recommended length for steam hose connecting a single
humidifier to a dispersion assembly is 10' (3 m). The maximum
recommended developed length for tubing or pipe connecting a
single humidifier 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 humidifier. However,
if the dispersion assembly must be installed at an elevation lower
than the humidifier, 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 humidifier on an exterior wall only if the wall is
properly insulated.
Dispersion control devices
See Figure 13-1 for recommended installation locations for the
dispersion assembly and associated control devices.
