(1) Instantaneous start-up current (maximum operating current of the smallest compressor(s) + locked rotor current or reduced start-up current of the largest compressor).
Values obtained at standard Eurovent unit operating conditions: evaporator entering/leaving water temperature = 12°C/7°C, condenser entering/leaving water
temperature = 30°C/35°C.
(2) Instantaneous start-up current (maximum operating current of the smallest compressor(s) + locked rotor current or reduced start-up current of the largest compressor).
Values obtained at operation with maximum unit power input.
(3) Values obtained at standard Eurovent unit operating conditions: evaporator entering/leaving water temperature = 12°C/7°C, condenser entering/leaving water
temperature = 30°C/35°C.
(4) Values obtained at operation with maximum unit power input.
* Values obtained in operation with maximum unit power input. Values given on the unit name plate.
