Check compressor for tightness, evacuate, charge refrigerant and oil
- Check for tightness.
- Check the refrigerant circuit (assembly) for tightness, as a whole or in parts, according to EN378-2 (or other applicable equivalent safety standards). For this, create an excess pressure, preferably using dried nitrogen. Observe test pressures and safety reference:
DANGERRisk of bursting due to excessive pressure!
Risk of bursting due to excessive pressure!
The pressure applied during the test must never exceed the maximum permitted values!
Test pressure: 1.1-fold of the maximum allowable pressure (see name plate). Make a distinction between the high pressure and low pressure sides!
- Evacuate.
- Charge refrigerant.
- Charge oil.
- Comission compressor/system and check function.
NOTICE
Polyolester oils are strongly hygroscopic.
Polyolester oils are strongly hygroscopic.
Moisture is chemically compounded with these oils. It cannot be, or only insufficiently, removed by evacuation.
Handle very carefully:
Avoid air admission into the system.
Use only originally closed oil container!
