Note! Since the illustrations in this service information are used for different model years and / or models, some variation may occur. However,
the essential information in the illustrations is always correct.
Topping up the lubricating oil
Warning! Do not mix oil types. Always use the correct type of compressor oil.
Note! Too much lubrication oil will impair cooling. Too little lubrication 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.
When installing new components the following procedures apply:
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.
Rapid leakage (hose rupture)
Rapid leakage often means that lubricating oil escapes with the refrigerant.
If the hose has ruptured, add 200 cm3.
