3. Compressor restart delay time
1) When the compressor is turne off, it restarts 5 minutes later.
- When the power is supplied for the first time, the compressor starts 5 minutes later.

5. Cooling safety shut-off function
1) When the compressor operates continuously for 150 minutes, the compressor is turned off for
5 minutes regardless of the cold water tempersture.
2) After the 5 minutes, the compressor resumes normal operation.
6.
Error display and load operation when the cold water temperature sensor is faulty
1) When the cold water sensor is OPEN or SHORT
- The bell rings “ding-ding-ding” and then the lower cold water indicator flashes on the FND.

When the cold
water temperature
sensor is faulty
2) When the cold water sensor is faulty, the compressor is turned off.
3) When the cold water sensor is OPEN or SHOR
T, the temperature is detected 100 times at an
interval of 10 ms. When the sensor returns to a normal status, the normal operation resumes.
7. Overcooling (Cold water temperature 1°C or lower)
1) When the water is overcooled, the compressor is turned off.
