Because my Trane XL19i was not properly evacuated during installation the contractor agreed to replace the filter/dryer and recharge with new Freon.
This was done yesterday, and I witnessed that it held a vacuum of 230 microns for several minutes.
My question concerns the old "filter/dryer" that was replaced. I attach photos of where it was installed, the item itself, the pipe that replaced it and the new filter/dryer.
Edit - Pictures may be too small to read the labels on the components, but the gray item is marked "Muffler Charge Compensator" and the black item is marked "Filter-Dryer"
I'm not the professional (just the homeowner), but is this OK?
