    Rzq200



    image.jpgimage.jpgRzq200 not cooling 15 bar standing pressure on suction and discharge ambient temp 25 degrees c upon start up discharge and suction shoot down to 3 bar in unison and icing up instantly from suction line of compressor all through the valves.
    Thinking there is a blockage I reclaimed 10kg of r410a pressure test and vac for 4 hrs recharged with r410a and ran and got same symptom any1 have any clues where I should look first or seen this before as I am lost it is worth mentioning that I didn't hear the ticking of the eev and there is 2 of them should I be looking at these first? Also worth mentioning that they are running 2 outdoor rzq200 to 6 fan oil units (3 on each) all on 1 controller is the eev controlled by the indoor sensors could there be a problem there?
