RE: Traulsen woes…

G31010JC… weighed the charge in after pulling it to verify it wasn’t low, weighed it in exactly. Ran the system and checked on it once it reached temp. Running a very low subcool, and a normal to high SH. This has a txv, which had just been replaced by another tech, along with the evap and drier. Tech support didn’t seem worried about the low head pressure (200 in a room that was 75 degrees r404) should have been more like 255 or so based on the ambient temp. It finally pulled down to -5 deg F, and shut off,  but we got a call that it wasn’t pulling below 8 degrees. The case was completely empty and hadn’t been messed with since the initial repair.

No, it’s just a self contained freezer with a semi hermetic on top of the case. No receiver or accumulator. Last time I worked on one tech support said it should be 30 over ambient, this other TSA said that wasn’t a big concern. The low subcool is bothering me, since it isn’t a system with a receiver. This system does not pump down either.
