    evcon emerson

    I am disconnecting an old evcon coleman condenser. there are some weird condenser shut off valves on the unit. At least that's what I think they are. Does anyone know what type of valves these are. I will attach a picture. All the nomenclature for the unit has faded an wore off. Any info on tools needed type of valve, refrigerant type will be greatly appreciated.

    There are standard schrader ports on the lineset.

    Just use those to recover the gas. The other tee stubs are probably a factory process tube of sorts for them to charge.

    The linesets appear to be an old precharged style that gets pierced when connected to the unit.

    Id guess R-22.

    I cant see clearly. I believe those valves close when you remove the cap.

    When you tighten the cap on, there is something inside the cap that pushes down on the valve and opens it.

    I could be wrong
