69L drop in...??????
Hello, I have an existing freezer room running on R69L. I am still a bit short on charge and have no 69L left. Is there any other refrigerant that I can drop in on top it...????
Thanks Scooter.

Short answer is NO. You shouldn't mix refrigerants without full knowledge of what you are mixing.
You could replace it though.Brian - Newton Abbot, Devon, UK

69l is a drop in for r502 i think,so recover it all send it for recycling then oil change ,flush triple vac recharge with 404a,and i would change oil again after one week of running of coarse change the filter drier,any suction core filters drain oil sep etc,bottom line is a big job best of luck,first thing to check is are you certain its short of refrigerant?.
