7. Maintenance Instructions
7.1. 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 significant changes in these levels, investigate them
immediately.
7.2. A preventive maintenance program should be developed for this equipment. To assist in your
development of this program, Cincinnati Sub-Zero has prepared a list of preventive maintenance
routines. While this list is not all inclusive, it will serve as a good base on which to build your own custom
preventive maintenance program. The establishment of such a program will add significantly to the life of
the equipment and will reduce the unscheduled down time on the equipment.
7.3. Print the following table to track preventive maintenance activities. Initial and date when each activity has
