This timetable is applicable to units operating in normal conditions with an average of 4000 hours per year. If
operating conditions are abnormally severe, an individual timetable must be made for that unit.
(1)
Tube testing required if aggressive water conditions exist. Applies to condensers only on water cooled units.
(2)
Schedule as per previous analysis result or at least once a year.
(3)
Year 1 to define equipment baseline. Subsequent year based on oil analysis results or schedule as per
vibration analysis.
(4)
Recommended at 40 000 run hours or 100 000 equivalent operating hours whichever comes first.
Schedule also depends on results from oil analysis / vibration analysis.
Seasonal start up and shutdown are mainly recommended for Comfort Air Conditioning and annual and preventive
maintenance are mainly recommended for Process application.
