5. Adjust the orientation of the stator so that it aligns with the
embossed recess in the fan deck.
6. Reconnect wires for stator temperature limit switch.
7. Pull motor harness tight through grommet and plug it in to the
control box harness and secure in the corner with snap-in
wire tie.
VERTICAL APPLICATIONS
Removing the Motor and Fan Assembly
NOTE: Due to press fit design of composite Rotor on Motor, it is
highly recommended that any time a motor is replaced the fan ro-
tor is replaced as well. The rest of the assembly may be reused.
See Fig. 28 for 2.4 Hp motor units; see Fig. 29 for 3 Hp motor
units.
1. Unplug motor harness from control box harness. See Fig. 25.
2. Unplug connectors from stator temperature limit switch. See
Fig. 25.
3. Remove six screws from the fan deck. See Fig. 31.
4. Allow the fan deck to drop into the slider tracks (careful not
to pinch body parts when the fan drops) See Fig. 32.
5. Slide fan deck assembly out of the panel opening that is being
used. Side panel access will not be allowed. See Fig. 33.
6. Remove the quarter round plates to free the fan assembly.

Disassembling Motor and Fan Assembly
See Fig. 28 for 2.4 Hp motor units; see Fig. 29 for 3 Hp motor
units.
1. Remove the four bolts that hold the orifice ring to the stator
2. Remove the orifice ring from the stator.
3. Remove three screws from the top of the fan rotor.
4. Remove rotor from motor.
5. Remove four screws connecting motor to stator flange.
6. Remove stator from motor.
7. If required, remove stator limit switch on the stator.
Reassembly of Motor and Fan Assembly
See Fig. 28 for 2.4 Hp motor units; see Fig. 29 for 3 Hp motor
units.
1. Place motor on flat surface.
2. If required, install stator limit switch on the stator with two
plastic push rivets (P/N: HH18HA597).
3. Fit motor wire harness into keyhole feature on the side of the
stator and pull wire harness out prior to fixing the motor to
the stator.
4. The 2.4 HP motors attach to the stator from the bottom by set-
ting the stator assembly on the motor. The 3.0 HP motors
attach to the stator from the top and are gently lowered into
the recess for the motor.
5. For the 2.4 HP motor, install four 1/4-20 x 1-in. hex head
machine screws (P/N: AC67AP170) to connect stator to
motor. Tighten to 50 in.-lb (5.65 Nm).
6. For the 3 HP motor, install six 1/4-20 x 1-in. hex head
machine screws (P/N: AC67AP170) to connect stator to
motor. Tighten to 30 in.-lb (3.39 Nm).
7. Install rotor on motor by lining up the rotor holes to the motor
holes. The rotor has self-aligning features that engage into the
motor holes. Press fan rotor down until it is flush with the
motor flange.
