Anyone with the FP sman480v manifold. When disconnecting the manifold from the refrigerant lines. I used to be able to open my ports to allow the pressures to equalize before removing the hoses to minimize the amount of refrigerant lost to atmosphere. Now I can’t seem to remember the process. Can anyone point me in the right direction?
