There are 3 CUs on this job, 2T, 4T, and 2.5T. The first 2 caps were undersized, I checked. Can't get specs for the 2.5T. Trying to do due diligence.
I'll apply,
thanks

R410 boils at minus 55.3°F
this is no where near ambient, in fact it is about 120°F below ambient

"at ambient of 90F, low side was about 33-35psi, high side was 200-225 psi, at about the 30psi of suction the compressor was tripped - vent temps were 44-48F. "

Those numbers look much better....

Evap and condenser need to be clean. Also cabin air filter if there is one, but back then that was unusual.

Bruce, the support engineer at Dole, is a top notch guy. I am surprised he didn't suggest going to a 404 system. You'd get to less than 40 with that
