*1 Values when ambient temperature is 25℃, circulating water temperature is 20℃, circulating water is at rated flow rate, and circulating water is clean water.
*2 When using clean water, be sure to use water that meets the water quality standards of the Japan Refrigeration and Air Conditioning Industry Association (JRA-GL 02:1994). The electrical conductivity should be at least 1μS/cm (higher conductivity indicates lower purity; Example: 100μS/cm). Use of circulating water that does not meet the specifications may result in poor chiller performance and premature failure.
*3 Based on chiller temperature gauge readings when load is constant, ambient temperature is 25℃, circulating water temperature is 20℃, and circulating water is at rated flow rate.
*4 An external temperature sensor (Pt100) is not included. Please prepare one yourself.
*5 Excluding protrusions.
*6 Use a power supply voltage within ±10% of the rated voltage.
*7 Values measured at 1m from the front of the device and at a height that comes to the center of the device, and at no load stability.
*8 When an error occurs, recorded at 5-second intervals from approximately 1minute before the error occurrence.
