(1) Maximum instantaneous start-up current (maximum operating current of the compressor + fan current + locked rotor current of the compressor).
(2) Power input, compressor and fan, at the unit operating limits (saturated suction temperature 10 °C, saturated condensing temperature 65 °C) and nominal voltage of
400V (data given on the unit nameplate).
(3) Standardised Eurovent conditions: evaporator entering/leaving water temperature 40 °C/45 °C, outside air temperature db/wb = 7 °C/6 °C.
(4) Maximum unit operating current at maximum unit power input and 400 V (values given on the unit nameplate).
* Maximum unit operating current at maximum unit power input and 360 V.
