7.1. IMPORTANT OPERATING AND MAINTENANCE POINTERS
The following synopsis is intended to be a handy reference of specific, important, Operation, Cleaning,
and Maintenance Factors, requiring most frequent attention. However, familiarity and understanding of
the detailed explanations and descriptions in the manual is essential.
Operation
1. Temperature setting must not be lower than ‐1 25°F (-120.5°C)
2. See Section 7.3 for temporary shutdown procedures / recommendations
freezer Cleaning
1. Cover control cabinet to protect from splash water. All motors are washdown, and thus do
not need to be covered.
2. Do not abuse door gaskets
3. Dry out freezer as well as possible after clean‐up. Leave all freezer doors open between shifts.
Maintenance
1. Check if all motors are running daily
2. Check solenoid valve operation at least weekly
3. Check conveyor belt slack frequently
4. Change conveyor drive gear box oil as specified in component manual.
7.2. DAILY START ‐ UP AND OPERATION
The freezer should be visually inspected before start ‐ up to make sure all covers are in place. Ensure
that the Cabinet Freezer is free of tools or any other objects. A check should be made for loose bolts,
damaged gaskets, etc., which should be repaired. Verify that there is still enough nitrogen in the storage
tank and that the pressure is adequate (40
‐ 60 psig is recommended).
The freezer should be dry from the previous night clean ‐ up. Check that the freezer is completely clean
and dry prior to cool down. Water remaining in the freezer may affect its proper operation, as the liquid
nitrogen will immediately freeze the water into ice. If not, the upper doors should be closed and the
fans and conveyors turned on for a few minutes to air dry the internal hardware before cooling down
the freezer with liquid nitrogen.
