Information On The Refrigerant Lines And A/C Compressor
Danger due to refrigerant coming out under pressure.
Danger of frost bite to skin and other parts of the body.
- Only loosen the connection point bolts when the refrigerant circuit is empty.
On most vehicles the A/C compressor is always driven when the engine is running, it doesn't always have a A/C Clutch -N25-. Therefore the engine may only be started when the refrigerant circuit has been properly assembled. For example; if the refrigerant lines are not connected to A/C compressor, when the engine is running the A/C compressor may heat up (via internal heat generation) so much that the A/C compressor will be damaged. Such internal heat generation results from the fact that - even with delivery near 0% - the compressor is confronted with a fixed resistance (sealed circuit).
Close open lines and connections on A/C compressor using suitable closure cap (to prevent possible penetration of dirt and moisture).
