Hi side about 150 low side about 15. Cap tube system, can't get at it
to check super heat. Thinking about converting it to a txv system but
with a 1/4 hp compresser i would never find a small enough valve.

Salad unit sounds like you want 35F or so, to keep the salads cold but not
frosty. With those pressures, it sounds like it's not metering enough
refrigerant. I'm wondering if the cap tube is too small, or too long.
Are you converting what was formerly a R-12 system? 134A needs a larger cap
tube ID, as 134A doesn't carry as much heat. Maybe try a R-12 replacement
blend like 409A, which runs in R-12 systems.
Low side 15 sounds a bit low, as though the system was starving.

....wow!
This is all just a Technical I.Q. test, Stormy. That's all. Regardless of
what other troubles are or are not present.
First he said,,,
>> This unit has a new compressor, cap tube and a clean condenser. Uses
>> R134A, won't go below 45 degrees.
*** It has a weighed in charge***
>>and the temp control is fine. Suction line is cool not cold. Any ideas?
and then he said,,,
> Yea had Vac pump on it for 3 hrs.
***Replaced strainer with a dryer.***
The clues are asterisked.
Here, let me help.
What event has happened to prevent accurately charging via refrigerant
weight anymore, and why?
-zero
