Professional Inspection
A substantial part of any good preventative maintenance program also involves professional inspection
and replacement of common maintenance components after an established interval. Such in-depth
inspection is particularly important when an unscheduled and/or long-term shutdown would seriously
affect production. Table 5—3 lists the items which require a professional service inspection whenever
environmental or operational conditions dictate. Contact a Cooper Turbocompressor trained and
authorized service representative for those procedures and for professional advice.
