Handling Precautions
Countermeasure for stop operation during night or long-term stop
In case of stopping operation during night or long-term, toggle the breaker and POWER switch to
"OFF".
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.
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 REFRIGERATOR ERROR lamp deactivate the refrigerator.
In this case, reduce thermal load by changing the fluid, or taking other appropriate measures.
