11.2 Precautions when commissioning
INFORMATION
During the first running period of the unit, the required power may be higher than
stated on the nameplate of the unit. This phenomenon is caused by the compressor,
that needs a continuous run time of 50 hours before reaching smooth operation and
stable power consumption.
NOTICE

burning of the compressor might be the result.
