I think it had r500 in it and i watched an old timer purge it for a few minutes then charge it up to "beer can cold". I think that the unit was from the early 60's. It was an old Chevy car dealership and the unit did the showroom.

Ace at least the drier is pointed in the right direction. looks like he saw the u-tube video on brazing.
HAHAHAHAHAHHAHAHAHAHAHAHAHAH sorry couldn't help myself.
One of my wealther customers allowed his nephew who is in tech school to tune up one of his 7 condensing units. Unfortunately the nephew started with the home theater unit. He told his uncle I did not know what I was doing because a few units did not have filter dryers in the compressor units (his terminology). The nephew and a few of his tech school classmates fixed the situation by installing the missing filter in the unit. The picture is attached. Unfortunately he installed one of those new discharge line filter dryers , and broke the line off at the condensing coil. He did somehow braze the line back on, which allowed the unit to run long enough for him to get paid and get out of Dodge. I was kind of happy for his efforts, I wanted to change this antique York out. So this is one example of a DIY doing good. I was thinking, maybe I could set this kid up with his buddies, you know an add in the Penny Pincher paper. Send him out on his own to replace and install discharge filter dryers all day and night. Later I could advertise to these folks, yeah that's the ticket....!

Somehow I doubt he was. I'll bet he was the low priced guy, though!

Isn't that wut that fan on top is for?? lol Constant air bleeder.
I wouldn't even attempt to bleed air off of a small unit. I'd pull the charge, evacuate and liquid charge what was in the cylinder. Once the cylinder was down to the last few ounces of liquid, I'd crack open the new stuff and top up the charge if needed. Either that or bleed air off of the recovery cylinder until it matches up with PT chart.
Haven't seen a schrader valve on top of a condenser in about 30 yrs.
i love the work maintenance guys give us some times.

I would write a very specific set of findings, and a detailed critique of the previous work and charges.
This is where that air depressor comes in handy.
I hate it when condensers air lock like that.
when i was first starting i saw a pic on a old RTU showing a hammer and punch with an arrow pointing to a spot on the condenser....maybe that's how he bleed the air off?
Oh SNap! Really? Damn that sucks to be cost effective! Think they learned anything? I bet you arent taking them back either!?!?! LOL.... sorry but thats to funny!
