Greetings! We are in the process of repairing a -80 freezer. The manufacturer mentions that they have used a mixture of R404A/R23 to fill the system. Can anyone elaborate how this is done? Are we to charge the system with two refrigerants? I have attached a picture of the backplate for reference. [link] [comments] |
