Case 1070 A/C Freon charge

Posted by Bud on April 17, 2003 at 17:49:43 from (67.202.89.230):

I Just overhauled my A/C system and I am re-charging with 134-A. So far all looks good and the system cools pretty well. The suction line sweats all the way to the compressor. The Hi side is at about 175 lbs and the low side starts at about 24 lbs but slowly goes down to zero while the unit is running. Yet the evaporator is cooling very well. I have so far put four cans in the system. I used a suction pump to evacuate the system before charging. My questions are; Why does my low side go to zero and yet the system appears to be functioning? Also since this is a large system with lines going to the roof, is four cans in the right ballpark? The ambient air temp while charging and looking at the guages was 83 deg. Any advice is much appreciated!
