Charging by sight glass

[KB Cool]

Had some txv's stuck wide open and you couldn't clear the glass without flooding out the compressor!!!!

I've seen sightglasses where it seems to just flow through. I had this one almost cleared. A little more gas would have done it.

So is the systems down or what ?

Be sure you pump down the system when your done adding freon to make sure your reciever is capable of holding the charge. Not doing this could cause you an unneccessary callback
