The vacuum pump and gauge set I bought from Harbor Freight. The pump was about $100 and the gauge set was about $60. The adapter at Locke Supply a local HVAC supplier was around $10.
SHOP MINI SPLIT INSTALL THREAD:
I have received my new mini split AC for my shop and have started installing it on the wall. So far l have hung the indoor unit and cut the pass thru for the wall.
The indoor air handler is hung on a sheet metal hanger that is easy to install with two screws into the stud walls.
The pass through is a piece of PVC that the liquid lines and wiring go to the outside unit. The unit came with a flimsy plastic pipe for the pass through. However, I had some spare PVC and more importantly I already had the right size hole saw for the pipe.
