PREVENTIVE MAINTENANCE
Freezers
Your equipment has been thoroughly tested and calibrated before shipment. Regular preventive maintenance is important to keep your unit function-
ing properly. The operator should perform routine cleaning and maintenance on a regular basis. For maximum performance and efficiency, it is rec-
ommended that the unit be checked and calibrated periodically by a qualified service technician.
The following is a condensed list of preventive maintenance requirements. See the specified section of the instruction manual for further details.
We have qualified service technicians, using NIST traceable instruments, available in many areas. For more information on Preventive Maintenance
or Extended Warranties, please contact us at the number below.
Cleaning and calibration adjustment intervals are dependent upon use, environmental conditions and accuracy required.
Tips:
• Fill an upright by starting at the bottom near the probe and add racks to one shelf at a time. Allow freezer to recover to set point between shelves.
• Fill a chest by starting at the left side near the probe. Filling with room temperature racks will result in a long pull-down time.
• Fill unit with frozen product to help overall performance; frozen water jugs, for example.
• Always make certain the vacuum relief port is free of frost and ice, to allow for timely re-entry into the freezer after a door opening.
