Humidier Option (Electric)

Wiring this device is the responsibility of the installer.

This device is not included in any Single Point

Power options. Fig. 2-62 represents a typical electric

humidier panel layout. The supply power knockout

is located in the bottom of the electrical panel as seen

in Fig. 2-63. All conduit beginning or ending inside

pressurized or conditioned areas (i.e. air handler) must

have all openings of conduit sealed to prevent air from

passing through. All air handling unit penetrations

must be sealed to prevent air and water leakage (see

IOM Section 5 “Penetrations and Grommet Details”).

Field provided disconnects must provide circuit

protection according to the humidier nameplate. All

eld wiring to the humidier must be in accordance

with NEC and local codes and by laws.
