Re: 577 U722 thermal insulator?



As I read the manual U722 does not require an insulator. Mine had thermal conductive grease on it.

Reference: 577-D1/D2 Service Manual 070-1414-00 - Sec. 8 Pg.12a for Unit Illustration, showing assembly details and Sec. 8 Pg.11 Item # 78 (U722) showing required mounting parts.
