My Emerson quite cool ac

Nice.

All that nonsense about propane is a load of bull. Consider there's only like one or two pounds of propane in the system. Even in the absolute WORST case scenario (that is, assuming a line bursts and something inside the unit is already on fire) there will be a bang and all the propane will have burnt up in an instant. Not a big deal. A more realistic scenario is that it develops a leak and that catches fire... in which case you'll have a little flame for a minute until the system is empty. But really, any leak is never going to have something sparking or at ignition temperature right in front of the leak. Besides... that new garbage refrigerant R1234y is flammable too, and somehow, that's A-ok. Let's not talk about the deadly toxic fumes it makes when burning, either.

Also, literally all of the 'incompatible refrigerant' argument is sort of a moot point. Because it's not the gasses that are dangerous to mix, it's the oils with the gasses dissolved in them (think CO2 dissolved in soda). Not even the oils themselves (although there is some technicality to that). Once the system is under vacuum, most of the refrigerant bubbles out of the oil, and that's that.

Checkrate/Likes 2 I finally fixed it it had a low refrigerant charge so I took out the r22 and replaced it with r290 or I just stole the gas bottle off of the grills and used that . I know what you will say it could leaks and start a fire or that it may destroy the compressor . Photos... < > Photo 1 of 2 View Full Size

Checkrate/Likes We had those units in all of the apartments back in the seventies. The last one died about five years ago.

He said that some one someone wanted to know if I would want it so we went and got it .

Checkrate/Likes *Vacuum* It took 4 hours for me to get 30 hg of vacuum . How I got the r22 out was probably illegal but I vented it to atmosphere because I don�t have a recovery machine or the money to by one.

Checkrate/Likes The reason it takes so long is because you're waiting for the refrigerant to slowly boil out of the oil. Can take a while sometimes.
