foreign matter.
(Note 1) The judgement level of part replacement period with Menu #5 "Maintenance information" should
be used as a guide. Determine the replacement period on the basis of the standard replacement years.
(See Section 7.5 "List of Periodical Replacement Parts.")
If the inverter is stained, wipe it off with a chemically neutral cloth to remove dust, use a vacuum
cleaner.
