INSPECTION SCHEDULE

levels of noise, vibration, temperature and pressure. If you encounter any signifi cant

An 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
signifi cantly to the life of the equipment and will reduce unscheduled down time on
the equipment.
If any of the following
scheduled inspections
require maintenance,
contact a qualified
service technician or
Cincinnati Sub Zero's
Service department.
