1 Answer


Low side should be about 40 to 50 psi with system running. Did you pull the system down before you charged it? Could be air in the system? If the system was open the accumulator could be saturated with moisture. If so, it needs to be replaced. If you replaced the compressor the accumulator &orifice tube should also be replaced. Then flush the system. Then pull down the system. If it holds vacuum for a minimum of 15 minutes (indicating no leaks) then recharge. HTH. - Jim
