Maximum instantaneous start-up current at operating limit values (maximum operating current of the smallest compressor(s) + fan current + locked rotor current of the largest
compressor).
Power input, compressors and fans, at the unit operating limits (saturated suction temp. 10°C, saturated condensing temp. 65°C) and nominal voltage of 400 V (data given on the unit
nameplate).
Standardised Eurovent conditions: evaporator entering/leaving water temperature 12°C/7°C, outside air temperature 35°C.
