The FAS/FHS size 072-180 units that have motors wired for
460-v, 3-ph, 60 Hz operation can be field-converted to 208/
230-v, 3-ph, 60 Hz operation. Rewire the motor according to
the diagram plate on the motor. After reconfiguring the mo-
tor, mark the motor specifying 208-v or 230-v operation re-
placing the 460-v sticker information on the units’ corner
post.
Fan motors are factory-installed on all units. Indoor-fan con-
tactors are located in the fan contactor box behind the side
access panel (see Fig. 15 and 16). Wire the thermostat to
the 24-v control circuit terminal block located in the side of
the fan contactor control box, according to Fig. 17 or the unit
label diagram. If the air handler is part of a split system,
complete the wiring from the condensing unit to the thermo-
stat shown in Fig. 17.
