INSPECTION SCHEDULE
In the day-to-day operation of this equipment, you will become aware of certain
levels of noise, vibration, temperature, and pressure. If you encounter any
signi• cant changes in these levels, investigate them immediately.
A inspection program should be developed for this equipment. To assist in your
development of this program, Cincinnati Sub-Zero has prepared a list of routine
inspections. While this list is not all inclusive, it will serve as a good base on
which to build your own custom program. The establishment of such a program
will add signi• cantly to the life of the equipment and will reduce unscheduled
down time on the equipment.
