f.Loosen set-screw that secures wheel to motor shaft, remove screws that secure motor mount brackets to blower housing, and slide motor and motor mount out of blower housing.

2.Remove and clean blower wheel as follows:

a.Ensure proper reassembly by marking wheel orientation.

b.Lift wheel from housing. When handling and/or cleaning blower wheel, be sure not to disturb balance weights (clips) on blower wheel vanes.

c.Remove caked-on dirt from wheel and housing with a brush. Remove lint and/or dirt accumulations from wheel and housing with vacuum cleaner, using soft brush attach- ment. Remove grease and oil with mild solvent.

d.Reassemble wheel into housing.

e.Reassemble motor into housing. Be sure set-screw(s) are tightened on motor shaft flats and not on round part of shaft.

f.Pivot blower access panel back into place. Adjust wire assemblies so that wiring follows proper pathways.

g.Reinstall unit access panel.

3.Restore electrical power, then gas supply to unit. Start unit and check for proper blower rotation and motor speeds during heating and cooling cycles.
