Preparatory work
Topping up the lubricating oil
Warning! Do not mix oil types. Always use the correct type of compressor oil.
Note! Too much lubricating oil will impair cooling. Too little lubricating oil will damage the compressor.
The oil must be topped up when repairing a leak or when replacing a component. The quantity required for the component in question will depend on
whether leakage has taken place slowly or quickly.
Slow leakage (longer than 24 hours)
With a slow leak, there is normally minimal risk of oil loss.
Rapid leakage (for example hose rupture)
Rapid leakage often means that lubricating oil escapes with the refrigerant.
Replacing components
When replacing components, the oil volumes set out below must be present in the new components or filled into the system through the service valve,
except for the compressor. See Compressor below.
Compressor
Preparatory operations for oil return
Measure the volume of the oil drained from the compressor.
Replace the volume of drained oil according to the table below.
