Commissioning
Information
Before the system is commissioned, check all safety and monitoring devices as well as control components in the system and in the machinery room for correct functioning! Calibrate sensors and pressure transducers, check signal tests and analogue/digital inputs and outputs.

Commissioning compressors for applications with R744 requires a particularly careful approach:
- There is a risk of overstress due to high pressure levels and possibly strong pressure fluctuations after start-up as well as lack of oil due to high refrigerant solubility in the oil!
- Observe operating conditions carefully and shut off evaporators temporarily in case of unfavourable operating conditions. Rectify causes/errors (Troubleshooting. In case of abnormal conditions, shut off compressors and evaporators.
- Monitor the system during the entire commissioning process!
In addition, the following information must be available:
- Design parameters
- e.g. max. permitted pressures of compressors and components, at standstill and in operation
- Temperature differences in heat exchangers, etc.
- Piping and instrumentation diagram
- Electrical schematic wiring diagram
- P&I diagram
