Topping Up the Lubricating Oil: Notes

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.

When installing new components the following procedures apply:

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):

Receiver drier	30 cm 3
Evaporator	50 cm 3
Condenser	30 cm 3
Tube	10 cm 3
Hose	10 cm 3

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:

Drained oil	Filling with oil
≥ 70 cm 3 oil	Replace the volume of drained oil with the corresponding quantity.
< 70 cm 3 oil	Fill with 70 cm 3 of oil.

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.

Drained Oil	Filling With Oil
≥ 70 cm 3 oil	Replace the drained oil volume with the same amount that was drained from the old compressor.
< 70 cm 3 oil	Fill with 70 cm 3 of oil.
