YT refrigerant charge

[murphman]

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.

The 11 machine is YTK9L6F1-CVCS. Serial starts YESM. The 123 machine is YTL6D8F2-CWH. Serial starts GDEM. Any help appreciated.

The YTL6D8F2-CWH has 1590# of R123.
