1.Using a 7/16” wrench, disconnect stator lead #6 from the auxiliary power stud on the left side of the control box. See Figure F.22.

17.With a 3/8” wrench, disconnect lead #5 from the center ground stud (nearest the control transformer). See Figure F.22.

18.Using a phillips screw driver, remove lead #3 from the top 50A circuit breaker for the 120/240V receptacle. See Figure F.22.

NOTE: This lead must be wound two turns clock- wise through the toroid (opposite in direction from leads #6A).

19.Disconnect lead #5A from the auxiliary power ground stud (left side of the control box, next to the 120V circuit breaker). See Figure F.22.

20.Using a 3/8” wrench, remove the two screws holding the control box to the top of the fan baffle.
