Handling Precautions
Recovery from a power failure
If the unit was deactivated in the middle of operation due to a power failure and is re-energized,
the unit automatically returns to the state just before the power failure and resumes operation. To
make manual recovery valid, make necessary settings according to "H06 function 2: Power failure
compensation setting" in the "Operation Manual for the Model CR5 Program Controller." If the
resumption of operation by automatic recovery is inconvenient, turn off the leakage breaker.
Abnormal refrigerator pressure
If the refrigerator operates in a high-temperature range, the refrigerator overload relay protecting
circuit may work to illuminate OVERLOAD lamp deactivate the refrigerator.
In this case, reduce thermal load by changing the liquid, or taking other appropriate measures.
About condensation
Condensate may generate depending on the operating conditions or the environment. Wipe any
condensate with a dry cloth or a rag.
About the circulating hose
The piping path in the unit employs a silicon hose. Silicon may discolor due to aged
degradation. Although it will not adversely affect performance or quality, we recommend
replacing hoses at least every two years to assure reliable operation.
When transporting the unit
Do not hold the unit on its side when you lift it for transportation.
Observe the installation procedures (P.11
~
12) when reinstalling the unit.
About replacement of circulating liquid
When replacing circulating liquid, first completely drain liquid remaining in the circulating path if
a different type of liquid is to be used.
