1) ⇒ Electronic parts catalogue (ETKA) .

2) The correct quantity of refrigerant oil is contained in the replacement air conditioner compressor and corresponds to the total capacity.

Oil distribution

• During operation of the air conditioner, the refrigerant oil in the air conditioner compressor prior to initial operation is distributed throughout the refrigerant circuit.
• Distribution of the refrigerant oil in the refrigerant circuit depends on the last operating mode of the air conditioner when it was switched off, the ambient temperatures and so on.
• Consequently, it is not possible to make a general statement about how the refrigerant oil is distributed within the refrigerant circuit.
• Observe notes on renewing components of refrigerant circuit ⇒ General information, air conditioning systems with refrigerant R744; Rep. gr. 87 ; Renewing components or ⇒ General information - air conditioning systems with refrigerant R134a/R1234yf; Rep. gr. 87 ; Renewing components; Renewing components .
