This chapter describes what you have to do and know to commission the system
after it is installed.
Typical workflow
Commissioning typically consists of the following stages:
1 Checking the "Checklist before commissioning".
2 Performing a test run for the system.
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
ALWAYS operate the unit with thermistors and/or pressure sensors/switches. If NOT,
burning of the compressor might be the result.
NOTICE
ALWAYS complete the refrigerant piping of the unit before operating. If NOT, the
compressor will break.
After the installation of the unit, first check the items listed below. Once all checks
are fulfilled, the unit must be closed. Power-up the unit after it is closed.
The indoor unit is properly mounted.
The outdoor unit is properly mounted.
The system is properly earthed and the earth terminals are tightened.
