NOTE: Proper polarity must be maintained for 115-v wiring If
polarity is incorrect, control center fault code indicator light will
flash rapidly and Alrnace will NOT operate.
FIRE HAZARD
Failure to %11ow this warning could result in serious injury,
death, or property damage.
Do not connect aluminum wire between disconnect switch
and furnace. Use only copper wire. (See Fig. 29.)

ELECTRICAL SHOCK AND FIRE HAZARD
Failure to fbllow this warning could result in serious inju W,
death, or property damage.
The cabinet MUST have an unintemlpted or unbroken ground
according to NEC ANSI NFPA 70-2002 and Canadian Elec=
trical (7ode CSA C22.1 or local codes to minimize personal
injury if an electrical fimlt should occur. This may consist of
electrical wire or conduit approved for electrical ground when
installed in accordance with existing electrical codes. Do not
use gas piping as an electrical ground.
J-Box Relocation
1. Remove 2 screws holding auxiliaQ' J-box. (See Fig 31.)
2. Rotate J=box 180° and attach box to leit side, using holes
provided.

ELECTRICAL SHOCK AND FIRE HAZARD
Failure to follow this warning may result in serious inju W,
death, or property damage,
If manual disconnect switch is to be mounted on furnace,
select a location where a drill or fhstener will not contact
electrical or gas components.
24-V WIRING
Make field 24-v thermostat connections at 24-v terminal block on
fm'nace control For proper cooling operation, Y wire from
thermostat MUST be connected to ¥ terminal on filrnace connol,
as shown in Fig. 30. The 24=v terminal block is marked fbr easy
connection of field wiring. (See Fig. 320 The 24=vcircuit contains
a 3=amp, automotive4ype fuse located on fi/mace control. (See
Fig. 33.) Any electrical shorts of 24-v wiring during installation,
service, or maintenance may cause lime to blow. If filse replace-
merit is required, use only a time of identical size (3 amp) and type.
The control will flash code 24 when fuse needs replacement.
NOTE: Use AWG No. 18 color-coded copper thermostat wire fbr
lengths up to 100 it. For wire lengths over 100 ft, use AWG No.
16 wire.
A( CESSORIES
l. Electronic Air Cleaner (EAC)
Two quick-connect terminals marked EAC-I and EAC°2 are
provided for EAC connection. (See Fig 33) These terminals
are energized with 115v (1 0-amp maximum) during blower
motor operation.
NOTE: DO NOT connect f:urnace control HI_M tem_inal to HUM
(humidifier) terminal on Thermidistat-f_L Zone Controller or simi-
tar device See Thermidistat TM, Zone Controller, thermostat, or
controller manufi_cturer's instructions fbr proper connection.
