My R22 system is about 15 years old. It has no filter drier on the liquid line. Nor anywhere else on the system
What I would like to do is just run the system R22 refrigerant through a drier that is looped onto my manifold gauge.
Where should I put the drier? On the High side or Low side of the manifold gauge? I would think the Hi side because that is where the drier normally goes on the system. This is however a bit different since it will loop through the manifold so not sure where it will be best to locate it. I will have a fitting on the low side of the manifold that will change the liquid to vapor. I am sure you have seen them. Imperial sells one called Qwik Charge.
I know there will be questions like "WHY NOT" just put one inline on the unit now. I don't want to open the system to put one on for one thing. And for those who are going to say "WHY DO YOU WANT TO DO THIS" please don't. If that is the only input you can deliver on this question please don't bother to reply to it.
I appreciate your cooperation and thanks you.
