I've been wondering if a 200 micron vacuum inside the large outdoor coil would be enough to suck in 28 oz of Refrigerant??

I would remove the test loop, and attach the Refrigerant hose loosely on the 1/4" line set port (Liquid Line).
Then, shoot a tiny bit of Refrigerant gas (bottle right side up) into the 10" fill hose to push out the air,
while quickly tightening the fitting.

When the liquid line service valve was opened (hex key), the vacuum would allow any liquid Refrigerant
that was released from the tank (upside down) to flow into the main coil, via the Strainer, EEV and cap tubes.

Of course, it would be only legal to DIY, if the Refrigerant was Propane..

Just wondering if this would work..?.
