Got a 300 ton compressor going in on an extended shell RTHA. Want to know from your experience some ideas. I have a rigging outfit coming in to make my lift, she is a beast at very near 5000 lbs. I have the machine pretty much down to parade rest, starter, control panel and disch line all pulled. All gas pulled and i am changing the isolation valves out as well.
I pulled the liquid line from the bottom of the economizer drain that sends liquid to th evap orfice because I have a leak there and I also want to clean and rust proof that piping. I put allinging marks across the flange at the evap, the evap orfic and the flange that attaches to the orfice. this is really the only allignment I can make, as the entire compressor is coming off.
It looks as if the oil housing tank brackets will help in allignment, but only to an extent.I am undecided if I want to keep the liquid drain out while setting this motor, or if it will be easier to match it back up at the orfice plate below and set both flanges under the compressor at the same time. What do you guys think?
