the SDL has which compressor? sanden?

bubbles mean the liquid column of refrigerant is not solid. it's either low on refrigerant, or the ambient temp is above the design... (110°F certainly qualifies) what's the high pressure? what's the condenser liquid temp? I would do everything in my power to VERIFY zero outside air is mixing in.
aux fan is running well. Correct amount of R12 I am nor so sure. i think I charged more but I am always a bit uncertain with the old cans...they sometimes seem to be low on R12.
I believe high side is around 250psi at 100F-110F ambient. Outside air is not mixing here.
I can see bubbles at these ambient temperatures...it is never below these temps right now and I see bubble all the time.
No idea about the condenser liquid temps. I can measure. Where? At the out let to the drier? I have a infrared thermometer.
