The boss purchased a new XLT recovery machine last week and I got to test it out today. Sucked down an old Comfort Aire (17 lbs R-22) and then shut off nicely like it's supposed to. Only problem is I can't get it to purge.
The YJ website has a video showing the system going down to vacuum when the purge feature is used; but after equalizing mine just sits around 75 psi low and 150 psi high. If I turn it off, it will equalize to 150 psi.
What am I doing wrong?
