*1 Values when Use Area Temperature 25°C, circulating water temperature is 20°C, and circulating water is at the rating flow rate.
*2 If using clean water, please use water that meets the water quality standards of the Japan Refrigeration and Air Conditioning Industry Association (JRA-GL 02:1994).
Use materials with an electrical conductivity of 1 μS/cm or higher (higher than this indicates poor purity, e.g., 100 μS/cm).
Using circulating water outside of specification may result in reduced chiller performance and premature failure.
*3 Based on display value of the main body temperature indicator when the load is constant, Use Area Temperature 25°C, circulating water temperature is 20°C, and circulating water is at rating flow rate.
*4This is the value when the circulating water flow rate is 4 liters/min. Avoid operating the pump at a circulating water flow rate of less than 4 liters/min, as this may cause the pump to malfunction.
*5 Excluding protrusions.
*6 Please use power-supply voltage within ±10% of rated voltage.
*7 Value measured at 1m in front, 1m high, and stable with no load.
*8 external temperature sensor is not included. Please prepare one yourself.
*9 When an error occurs, recording is made at 5-second intervals starting approximately 1 minute before the error occurs.
