When I turn it off the low pressure goes to the limit ... and when I turn it on it goes back to 90 or 100 psi
When it is switched on it is not going to be empty it remains stagnant in that pressure 90 psi
Friend coordinates the answer to help you
1- compressor walking how many psi
2 compressor stopped how many psi
Only those two data
If the gas used by your device is r22a, you are exceeded by gas. This refrigerant works with 65 psi in the suction and high between 230 to 250. Just as you are going to nail the compressor
So what I have to do is take out gas ... and nothing else. At the time I solved the loss to the valve could be leaved
By the time I welded the valve it could have broken inside. "Or the capillary that passes x below." It is the first time I have a job like this ... the compressor starts the fan too ... only the stopcocks cool and nothing more ... the valve raises a lot of temperature
Put the manifold and see it slowly taking gas waiting for the system to stabilize until it reaches 65psi
