

Compressor oils (specification 362.0)

BB00.40-P-0362-00A


Only use the approved compressor oil in each case.
If it is proven that a different compressor oil has been used, we will refuse to reimburse costs within the warranty and goodwill period. Daimler AG reserves the right to perform reexaminations.


Correct oil filling quantity in refrigerant circuit must be corrected.
In the event of an incorrectly measured oil filling quantity, the refrigerant compressor may be damaged.
