CAPACITOR REPLACEMENT

NOTE: Capacitors must always be replaced in matched sets (C1 and C2 as a set).

When replacing Capacitors, remove the entire FET heat sink assembly, including the capacitors and switch board, as a unit.

Disassemble and reassemble only one unit at a time. Use the other unit as a model during reassembly so that all parts are reinstalled prop- erly.

14.Remove the two 3/8” hex head nuts from the top of the through-bolts. The hex nuts are located on top of the fan shroud. See Figure F.34.
