Installation
Selecting a location
Important:
Install humidifier only in locations that meet the
following temperature and relative humidity (RH)
requirements:
Maximum ambient temperature:
104 °F (40 °C)
Minimum ambient temperature:
41 °F (5 °C)
Maximum ambient humidity:
80% RH (non-condensing)
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 23.
• 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 28.
Before installing a dispersion assembly or interconnecting
piping, review all pitch requirements in the “Dispersion” section
of this manual.
• Required clearances (see Figure 9-1)
• Electrical connections
Electrical power supply connections are at the lower or upper
right rear corner of the unit. See “Humidifier wiring” on Pages
19 and 20.
• Supply water and drain piping connections
Water supply piping and drain connections are at the bottom of
the cabinet. See “Piping” on Pages 14 and 15.
• Exterior wall insulation
Install the humidifier on an exterior wall only if the wall is
properly insulated.
Dispersion control devices
See Figure 22-1 for recommended installation locations for the
dispersion assembly and associated control devices.
