After r134 conversion, what pressure should I see on low side?
I converted my system a year ago, works pretty good, want to be sure it's fully charged and I don't know what pressure I should see.
Thanks,
Ken

I usually look for about 25-40 on the low side, and 200-250 on the high side, with the system running on MAX A/C, and blower on high.
Also, the low pressure cutout shoud be set to 22 PSI.

One other thing you may want to consider since 134a is cheap is installing a VOV. It will make the converted system work better since 134a is touchy. http://www.acsource.com/cgi-bin/Soft...0756+994805495
