Vac pump on suction or discharge valve
Hi
To create vacuum inside the compressor I was wondering if it is best to connect the vacuum pump to service valve on suction valve or service valve on discharge valve ?
Or will it give the same result no matter which one I connect it to...
How long time do I have to run the vac pump to make sure all air is out of the compressor housing.
Thank u......
