Title: Selectivend s48 charging
Post by: on March 23, 2005, 01:48:41 pm
I have a Selectivend S48 Dr Pepper machine with a Blissfield compressor. It does not attempt to cool but the compressor does turn on along with the evaporator fan and condenser fan. I have made a drawing of what the compressor deck plate tag looks like but there are a couple of areas that I can't read. Does somebody know how much R12 it takes? I have been told by a restorer that he has used a product called Freeze 12 (I know that it is intended for automobiles), the only thing is to charge the compressor with 10% less than what it calls for of R12. I picked up two cans of Freeze 12 w\UV dye. This way I can tell if there are any leaks in the system. Are the HS and LS numbers good to go off of to get it fully charged?

Freeze 12 is a replacement refrigerant for r-12. the pressures listed on the plate are test pressures at the factory for leaks. I would expect on an r-12 box "WARM" low sid around 20-30psi high side around 130-190 depending on outdoor or "ambiant" conditions """COMPRESSOR MUST BE RUNNING TO GET THESE PRESSURES""" ALSO CONDENSOR FAN good luck
