※1: Operating Conditions: Chilled water temp.: 20 °C, Ambient temp.: 32 °C. Cooling capacity is at least -5 % of listed figures.
※2: Source voltage phase unbalance should be less than ±3 %.
※3: The figure noted is when operating at the highest capacity in the normal operating range.
※4: Continuous current load fluctuation within ±10 %, and with stable ambient temp. and power supply, etc. Does not include starting times or when the cooling load is too small, in which case the compressor may cycle on and off.
