    Confused How to connect a Trane compressor

    I was working on a portable HVAC unit for Frontier airlines that they use to heat and cool aircraft while at the gate. This monster has a 350 HP Cummings diesel turning an 18 KW generator that run two 15 ton Trane compressors. The blower and condenser motor are both 15 HP. I was having issues reconstructing Tranes 138.5 bend in the 6" they did it coming off the compressor. Hot, tired and loaded with a box of fittings this is what I came up with.

    next time around even on a normal scroll unit change out,remove the mounting bolts at the base of the compressor turbo that discharge and it will pop out of the compressor wire wheel all the paint off before applying heat same with the suction.major effort should be taken to remove the lines directly out of the compressor discharge and suctions..and if you do the older scrolls never cut the lines Trane has different ODs on factory pipes

    Not that this helps now but does Trane possibly have a pipe kit for that?

    the original primer colored scrolls had a pipe within a pipe on the suction and cutting it led to nightmares that is why I did that pop out trick these still can be POPPED out keeping the line intact
