Holes are on both sides of the furnace cabinet to facili­
tate wiring.
Install a separate (properly sized) disconnect switch
near the furnace so that power can be turned off for
servicing.
Before connecting the thermostat or the power wiring,
check to make sure the wires will be long enough for
servicing at a later date. Remove the blower access
panel to check the length of the wire.
Complete the wiring connections to the equipment.
Use the provided unit wiring diagram as shown in fig­
ure 55. Use 18-gauge wire or larger that is suitable for
Class II rating for thermostat connections.
Electrically ground the unit according to local codes or,
in the absence of local codes, according to the current
National Electric Code (ANSI/NFPA No. 70). A green
ground wire is provided in the field make-up box.
NOTE - The 95AF2DFV furnace contains electronic
components that are polarity sensitive. Make sure
that the furnace is wired correctly and is properly
grounded.
One line voltage "EAC" 1/4" spade terminal is provided
on the furnace integrated control. Any electronic air M
cleaner or other accessory rated up to one amp can be
connected to this terminal with the neutral leg of the cir­
cuit being connected to one of the provided neutral ter­
minals. See Figure 56 for control configuration. This
terminal is energized when the indoor blower is operat­
ing.
