Refrigerant Oil

Rapid leakage (e.g. hose rupture)
Rapid leakage often means that lubricating oil escapes with the refrigerant.
When replacing components, the following oil volumes shall be found in the new components or shall be filled in the system through the service valve, except for the compressor (see the section "Compressor" below):




Compressor

Oil return when reusing compressor:
- measure the volume of the oil drained from the compressor
- replace the volume of drained oil according to the table below:






Oil return when replacing compressor:
- Drain the old compressor of oil, and measure the amount.
- Drain the new compressor of oil (the amount may be below specified value since it is not possible to drain all oil from the compressor).
- Use the table below to fill the new compressor with the right amount of oil.






Caution! When installing completely new system:Check that there is oil in the compressor. The other components should contain no oil.
