How much 134a

[chris989]

When i converted the pancake compressor from r12 to 134 i changed the orifice, accumulator, and flushed..

When i change from the R4 compressor (134) to the new sanden I changed the accumulator/dryer/hoses and flushed. (did not change the orifice again).

I guess i am undercharged at 36 ounces,, I read 51 ounces of 134 and if 4 seasons is correct at 52 ounce of r12 that would equate to ~42 ounces of 134.


I will continue to add and report back
