5. Place the control box side evaporator orifice (item 8) around the fan shaft. The draw on the control box side evaporator orifice
should face the evaporator blower (toward the compressor side of the unit). The compressor side evaporator orifice will be
fastened to the outside of the evaporator blower housing (item 19).
6. Slide the fan shaft into evaporator blower housing. Slide evaporator blower (item 9) over the compressor side end of the fan
shaft. The blades on the evaporator blower must be oriented as shown in the “Evaporator Blower Orientation” illustration.
7. Place the compressor side evaporator orifice (item 7) around the fan shaft before sliding the fan shaft through the compressor
side of the evaporator blower housing. The draw on the compressor side evaporator orifice should face the evaporator blower
(toward the control box side of the unit). The compressor side evaporator orifice will be fastened to the inside (blower side)
of the evaporator blower housing (item 19).
8. Slide the fan shaft through the compressor side bearing assembly (item 6). The compressor side bearing is self-aligning and
does not need to be adjusted.
9. Tap one Woodruff key (item 17) into the keyway on the compressor side end of the fan shaft for the compressor side
condenser blower (item 3).
10. Tap one square key (item 18) into the keyway on the control box side end of the fan shaft for the control box side condenser
blower (item 4).
11. Slide the control box side bearing assembly (item 11) onto the control box side end of the fan shaft. Make sure to align the
tabs on the inner race of the bearing with the slots in the fan shaft collar. Orient the control box side bearing as shown in the
illustrations with the oil plug and the vent on the front side of the bearing assembly. Fasten the control box side bearing to the
mounting bracket, but do not completely tighten the mounting hardware
