hope someone can help with this....ac blows warmer from drivers side...after recharging it got a little cooler...refrig measures 14 bars when not running and 16 when running...had a guage on when refilling and stopped at 147 lbs on high side and 62 pounds on low side...note i only filled on high side...

WHAT IS THE MAX PRESSURE (HIGH & LOW ) FOR THIS SYSTEM???


will try and follow the instructions for rebuilding the duovalve.

system does not appear to be leaking...will confirm by taking the high and low pressure again today.

thanks in advance for any advice

 

well i think i now understand both sides of the DUOVALVE "TOO CLEAN OR NOT TO CLEAN" issue.

when i opened the valve it was electric...actually electromagnetic...and it was clean as a whistle...not the culprit here...but maybe in the vacuum/air operated
it is a different result or i guess it just was not my valve.

took readings yesterday and again this am

yesterday @100 degrees and done on black top

1 107
2 103
3 91
4 82
5 107
6 186
7 14
8 143

note this was also done after it had been recharged and the gauages read 147 on the high side and 62 on the low side.


today after cleaning the duovalve and spending the night in 78 degree temp the results were as follows

1 85
2 102
3 67
4 66
5 69
6 136
7 13
8 141

i am going to my buddies to check the refrigerant pressure on both the high and the low to rule out a leak but i think i will also purge the refrigerant and renew including the 1st can on the low side...note we only loaded the refrig on the high side...my friend knows more about this but i read here many people advising loading some on the low side????? ANYONE HAVE AN OPINION....PLEASE HELP 1oldbiker!!!!
