I have an old R-12 Cold machine that I would like to try to recharge. What pressure does the low pressure side draw down to when operating with the correct amount of refrigerant present? - thanx.

pressures
With a small evaporator (freezer bin which measures 10"x6"x11") ambient running pressure should be 8 PSI (R12). The large evaporator (15"x6"x12") should be 12 PSI. After cycling begins, small evaporator should be around 5 PSI, large 7 PSI.
