ries (Humidifier and Electronic Air Cleaner)
The furnace integrated control module is equipped with line
voltage accessory terminals for controlling power to an optional
field-supplied humidifier and/or electronic air cleaner.
Turn OFF power to the furnace before installing any accessories.
Follow the humidifier or air cleaner manufacturers' instructions
for locating, mounting, grounding, and controlling these acces-
sories. Accessory wiring connections are to be made through the
1/4" quick connect terminals provided on the furnace integrated
control module. The humidifier hot terminal is identified
as 120V HUM-H, its neutral terminal is identified as 120V
HUM-N. The electronic air cleaner hot terminal is identified
as EAC-H, its neutral terminal is identified as 120V EAC-N.
All field wiring must conform to applicable codes. Connections
should be made as shown. (See Figure 30.)
If it is necessary for the installer to supply additional line
voltage wiring to the inside of the furnace, the wiring must
conform to all local codes, and have a minimum tempera-
ture rating of 105°C. All line voltage wire splices must be
made inside the furnace junction box.
The integrated control module humidifier terminal 120V
HUM-H is energized with 115 volts whenever the induced
draft blower is energized. This terminal can also be used
to provide 115 volt power to a humidifier transformer. The

Junction Box Relocation

Line voltage connections can be made through either
the right or left side panel. The furnace is shipped con-
figured for a left side electrical connection. To make
electrical connections through the opposite side of the
furnace, the junction box must be relocated to the left
side prior to making electrical connections. To relo-
cate the junction box, perform the following steps.
1. Remove the burner compartment door.
2. Remove and save the two screws securing the junction
box to the side panel.
