In the unit there are two protector, air breaker for compressor motor is GV2-M22C,whose parameter is overload
current:20~25A,short circuit current:327A,415V; air breaker for fan motor is GV2-M08C, whose parameter is overload
current:2.5~4A,short circuit current:51A,400V.
The noise level will be measured in the third octave band limited values, using a Real Time Analyser calibrated sound
intensity meter. The noise level is measured at 2meter in front of the unit, 1.5 meter high to the ground.
When starting up the complete unit, the compressor will start up one by one and will not start up together.
