    YT refrigerant charge

    Trying to find factory charge by weight for two YT machines. One is r-11, about 25 yrs old. The other is 123, about 15 yrs old. Have found several manuals but nothing mentioning charge weights. Can anyone help?

    Refrigerant charges weren't always the same from year to year. Need to know the complete model and the first four letters in the S/N to be sure. I think the chart posted above is too new to be accurate in your case. Style J chillers had completely different refrigerant charges than their earlier predecessors. If your chiller does NOT have an Optiview panel the numbers posted above are inaccurate.

    True, the manual was for YT's with Optiview.
