I have just purchased 2 larkin scroll outdoor cond. units that have been supposedly factory charged and pressurized with "dry air"
here is my dilema, on both sealed units the Alco refrigeration sightglasses read wet "yellow" these are brand new units "never run". Shouldnt the sightgjlasses read dry(green)?? There is pressure at the suction and liquid line schraders.

why are they reading wet??
