Do any of you know of any threads where it has been discussed pumping down microchannel coils?
By using the condenser and compressor to pull the refrigerant into the condenser with no ill effects. I know Copeland and Microchannel coil manufacturers would say no, but they have to do it. Who's seen a failure by doing it? Or is it just factory bs? This should be a new thread. There are a lot of things that we do that aren't quite to manufacturers recommendations, but are always done and have been there for years and years. Because frankly they're trying to cover their butts. My vote is to pump down a micro channel coil, depending upon line set length.
No means no. Why risk damage to the equipment? Knock the dust off your recovery machine and USE it.
This one didnt, it had a muffler but no drier inside the condenser..
This image by the way was taken as it was being installed, so dont kill me if you can see the crankcase cables just sitting there.
Per the Luxaire parts list and diagram, that is definitely a MUFFLER, not a LLF. The parts states the LLF is a field installed extra that can be ordered.
Here is the link to that for questions...
This is for the York branded unit, but the exact same as the Luxaire.
Getting technical, should be in the Pro forum.
This assumes that you know the difference between the discharge line and the liquid line. Don't ever put a filter-drier on the discharge line (unless it is hollowed out and empty and says "muffler" on it.
The real danger is a hydraulic burst.
Same reason they warn us about overfilling recovery cylinders.
If you leave no room for expansion and you fill to the brim and then the hot sun comes out.........boom.
the drier is on the liquid line right before it leaves the inside of the unit. i can see it in the picture. about 1-1/8" round and 6" long
