 Control Systems

Table 3.0 Annual Maintenance Schedule

In addition, inspection and preventive maintenance should also be performed on the freezer and its 

mechanical parts. Refer to owner’s manual for details.
If any intermittent alarm or defect with the Cryostorage System is observed or suspected, it should be 

investigated and remedied immediately even if this falls outside of the normal maintenance schedule.

CS200 SERIES Control

Examine for exposure to moisture, wear and tear, connector problems, and 
damage to the faceplate or buttons. In addition, periodic firmware updates 
may be important

Harness Assembly

Examine for damage to the cable and damage to connectors, 

Battery

Examine connection cable and connector for damage. Examine vinyl  
cover for damage. Replace every 3 years

Solenoid Valve

Examine wires and connector for damage. Replace every 2 years.

Lid Switch

Examine lid switch pickup and wires for damage. Replace if necessary

Level Sensor Assembly

Examine for damage to wires and connector. Replace every 3 years

Thermocouple Assembly

Examine for damage to wires and connector.
