    Between these two pics there are three wrong things. Two are very wrong and the third depends on what you were taught. I took these pics today (5/19).

    I think I see all 3 but want to let less knowledgeable and gifted people than me answer it.

    lmtd,
    You are correct on all four. How on earth did I miss the 90 ? Must have been a long day. I have seen so many liquid line driers on discharge lines this year. The site glass always cracks me up. There is a new Trane sitting to the left of this unit that I helped install last year. It'd be nice if this old unit would die soon.

    Yes that was them. But one more. The heater wire nut junction should be under the compressor terminal cover and the wire nuts taped.

    Isnt that the thermal overload?

    And here I thought that the smaller diameter line was the liquid line, and the larger diameter was supposed to be the gas suction line, so the drier would have been in the right place.

    Is the piping diameter wrong too? I must be missing something, but that's OK I'm just a curious HO.

    Seriously? There are no external thermal overloads on anything other than window unit and refrigerator compressors. NOTICE: There are solid core driers that are designed to be installed on the hot gas discharge line. York uses them all the time. Made by Sporlan I believe. Before condemning driers on hot gas lines make sure it isn't one of these models. Of course everyone would recognize a discharge muffler.

    Out of all the HACKERY in Arizona I have never seen a site glass on a HOT GAS line. What would you be looking for??? HA HA HA. Priceless.

    What's more amazing, is that you said you have seen MANY that way. That tech must have ran lose a long time before someone saw and corrected him. If anyone ever has that is!

    Did you forget the old scroll's with thermal overload on the top that always leak.

    That filter-drier is not on the liquid line, it's on the discharge line of the compressor.

    The small line doesn't become the "liquid" line until it reaches a point where all refrigerant would have been condensed into a liquid. It's a high pressure vapor at the point where that is installed.

    This can be horrible, or not really all that bad.

    It's a Sporlan drier, and some ice machine manufacturers used to put them on the discharge line.

    What would make it real bad would be if the filter-drier clogged, and there was no high pressure switch on the compressor. (which I don't see there) Could turn the whole system into an irreparable mess. A veritable superfund site inside the pipes.

    BTW.

    That's some snazzyass discharge line piping!

    45's, Street 45's, Short turn 90s, sweeping bent copper barely straightened as it came off the roll, 95-5 or Aqua-pura? We'll probably never know. (Maybe Dutch-boy solder???)

    The blackened moisture indicator indicates excessive heat, but I'll bet it wasn't from the soldering process.

    Gee, I wonder if they ever got that sightglass to clear?

    I see, the condenser coil turns the gas into liquid (it condenses! LOL) and the filter would have been OK *after* the condensing coil. It makes sense now, thanks!

    Took one look at those pics and crap, there goes another keyboard! ROFL!

    Let me guess...this unit is a no-cool call because, oh, maybe because the drier in the discharge line shot its guts all over the system by now?
