Disconnect the electrical power leads from the motor. For an X-Strut frame remove the bolts and washers
holding the fan struts to the fan housing and remove the fan drive unit in one piece, this includes the struts, motor,
bearings and strut brace. See Figure 3A. For an H-Strut frame remove the bolts and washers holding the fan
struts to the fan housing and remove the fan drive unit in one piece, this includes the struts, motor base, motor,
bearing base, and bearings. Make sure that all the washers are removed from the fan housing in all 4 locations
on the outside of the fan housing. See Figure 3B. Be sure not to damage the bolt holes in the housing, as these
holes will be reused.

Struts into the fan housing and align the outermost holes in each strut leg with the outermost holes in the housing
and fasten in place using (4) bolts [D] and wing nut [J]. See Figure 4B.
