I feel like a dummy asking this but how do I get the refrigerant out of the first can?
This is exactly what I did
I pulled a vaccume for 45 minutes
I turned off the high and low sides on the gauges and then shut of the pump.
I made sure the vaccume held at the same -28 for another 45 minutes.
Then I closed the valve on the yellow wire.
I screwed the yellow hose all the way down on the can and opened the valve.
Then I opened the low(blue) side on the manifold.
After about 10 minutes of trying to warm the can up with my hands...it never really got cold at all.
I decided I would turn on the truck and try to kick on the compressor. All controls on max and all the way cool I turned the compressor switch on but the compressor never actually spun. Probably because the low pressure switch is sensing no pressure.
My question is, what am I doing wrong and how can i fix this?
Im using 5cfm robinair pump and snapon r134 gauges if that matters
If you're sure you're getting refrigerant flowing into the system, try putting the refrigerant container in some warm water....that should increase the pressure in the container and force more into the system. Otherwise, jumper the low pressure switch to force the compressor to run.
Are you sure the gages are depressing the shrader valves on the system? What kind of gage set do you have? Did the high side gage rise at all when you punctured the can? (or are you using a 30lb tank) The vacuum should have pulled most of the charge in.. It appears that you are not depressing the valves, which means if they aren't you will need to puull your vacuum again, as you would have just vacuumed the lines..Hope this helps..
Freedoms just another word for nothing left to lose
i have a snapon gauge set. Im such a dummy. The snapon has a nipple on the connector you connect to the can on the yellow hose. I figured it was enough to peirce the seal but it is not. I am going to get a can tap now.
Do I have to suck the air out of the system again? the full 45 minutes?
