Danger!

Risk of explosion caused by welding or soldering work on closed air conditioning system. Risk of poisoning caused by inhaling overheated refrigerant vapors. Risk of injury to skin and eyes caused by contact with liquid refrigerant.

Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been discharged.

1

Drain new refrigerant compressor

Drain compressor oil through the openings for low pressure and high-pressure lines.

2

Drain removed refrigerant compressor

Use suitable measuring cup.

Checking

3

Check condition of compressor oil

Check compressor oil for signs of contamination (color dark gray - black).

Measure

4

Measure quantity of compressor oil drained from removed refrigerant compressor

Fill

5

Fill new AC compressor

Pour the quantity of oil drained from the removed refrigerant compressor plus an additional 20 cm3 into the new refrigerant compressor. Always use new compressor oil.
