* Permissible limits of voltage range at which unit will operate satisfactorily.

²Unit ampacity = 125 percent of largest operating component's full load amps plus 100 percent of all other potential operating components' (EAC, humidifier, etc.) full load amps.

³Length shown is as measured 1 way along wire path between unit and service panel for maximum 2 percent voltage drop. ** Time-delay fuse is recommended.

NOTE: Use AWG No. 18 color-coded copper thermostat wire for lengths up to 100 ft. For wire lengths over 100 ft, use AWG No. 16 wire.

NOTE: For 2-speed applications, refer to Sequence of Operation section.

III.ACCESSORIES

1.Electronic Air Cleaner (EAC)

The control center EAC terminals are energized with 115v (1.5-amp maximum) during blower operation.

a.Two extension leads are connected to the control center EAC terminals to assist field installation of an EAC. (See Fig. 25.) To use these leads, proceed with the following:

(1.) Strip EAC power lead insulation approximately 1/4 in.

(2.) Insert stripped end into factory-supplied black lead's butt connector and crimp to secure.

(3.) Strip EAC neutral lead insulation approximately 1/4 in.

EAC-ELECTRONIC AIR CLEANER TERMINALS (115-VAC 1 AMP MAX)

(4.) Insert stripped end into factory-supplied white leads's butt connector and crimp to secure.

NOTE: If desired, cut butt connectors off factory leads and strip insulation approximately 1/4 in and use field-supplied wire nuts to connect.

b.An alternate method to attach EAC lead to control center is the following procedure:

(1.) Remove 2 screws securing the control box to furnace blower shelf.

(2.) Remove and discard 2 factory-supplied leads from control center EAC terminals.

(3.) Strip EAC power leads insulation approximately 1/8 in.

NOTE: The control center EAC terminals are sized for 12 gage maximum, solid or stranded wire.

(4.) Route EAC leads through right-hand wire grommet.
