Funny you noticed that NOL
It's on a 1/8" pipe long enough to put it anywhere, so I just tucked it down there until I finish insulating that one. But the pipe comes up from the top of the pressure line, reverse flow to the gas. Best way to avoid oil issues inside, but when I'm done I can move it back above the pipework.
I'm liking having the pressure switch on a more flexible 'large captube' that way so I can place it wherever there's room. Beyond that, it's much easier to braze it to a small pipe, less heat so less risk of damaging the diaphragm inside.
Shame you're not building right now Scott, like watching you build
Though I had a quick look at the CL in Atlanta and you get a lot of cheap small window units there too
though they do tend to come up cheap more often here with the pathetic summer weather we get
Gives me something to play with when there's no one ordering anything.
