Reconnect the wiring to the motor.
Install the impeller onto the motor shaft and position it so that there is the same distance between the
end of the shaft and the wheel bushing using the measurements previously written down.
Position the fan on the motor shaft so that one of the 1/4-20 set screws can tighten against the flat
edge of the motor shaft.
Reinstall the fan assembly back into the fan housing. Locate and line up the two threaded location
posts at the top and bottom of the tower near the securing bolts (Figure 13 and Figure 14). Secure
using the four 1/4” bolts removed earlier.
Note
that there may be some resistance when reinstalling
the fan assembly back into the housing.
Rotate the impeller to ensure that it rotates freely.
Reinstall the front grill.
Power to the fan unit can now be re-established.
