Installation:
Drain remaining cold oil from old compressor and pour into a measuring container. Also pour extracted refrigerant from Service station into the measuring container and note the total quantity of oil. Refrigerant from air-conditioning system and old compressor cannot be re-used: dispose of this fluid in the correct way.

Clean measuring container.

Drain all refrigerant from new compressor into a suitable container and refill compressor with correct quantity of refrigerant as calculated beforehand.

NOTE: The rest of the new refrigerant can be filled into the supply container for the Service station. Refrigerant must be disposed of in the correct way. Refrigerant is hygroscopic and therefore must not be stored in open containers.
