Good afternoon friends I have a doubt with this FF8.5BK clutch engine is for a 4-door conservation fridge. I need to know what coolant I should use since the specifications of the engine says that it is mixed and here in Venezuela there is none and searching the web says that it uses 401 (mp39) and here they say that it is the replacement of R12 and the truth is not I know what to do if I use R12 or not. Q you advise me please and thank you

The manual I have says that it uses R-12 (the BK series) is a compressor to work at medium / high temperature HBP. The replacement mixture is R-600a (trade name MO49, MP39, etc.), since it is a mixture, you must supply it in a liquid state to the system and allow time for pressure stabilization in the load.

Framework If you have R12 that serves you, you can load it in liquid or gaseous form, well if they do not have practice, it is best that you load it in gaseous form, many of us load it in liquid form, little by little and giving it time to settle in the system, but as I say, if you don't have much practice, do it in a gaseous way, luck.
