This chapter describes what you have to do and know to commission the system
after it is installed and configured.
Typical workflow
Commissioning typically consists of the following stages:
1 Checking the "Checklist before commissioning".
2 Performing an air purge.
3 Performing a test run for the system.
4 If necessary, performing a test run for one or more actuators.
5 If necessary, performing an underfloor heating screed dryout.
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
Before starting up the system, the unit MUST be energised for at least 6 hours. At
negative ambient temperatures, the compressor oil needs to be heated to avoid oil
shortage and compressor breakdown during startup.
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.
1 After the installation of the unit, check the items listed below.
2 Close the unit.
3 Power up the unit.
You read the complete installation instructions, as described in the installer reference
guide.
