    Something dont jive here . The CH530 Earthwise purge doesnt have a sight glass on the purge tank , the Purifier does . The CH530 Earthwise does have a float switch , the Purifier doesnt so which purge have you got ??

    You are correct. I should have completed my thought to read "... so it won't suck itself full of air the next time you change the drier" Which appears to be what may have happened this time. I say "may" due to the possibilty that maybe it was already full of air.

    I have 24 years working in HVAC field as a service engineer and contractor mostly working with Carrier units but not too much time with TRANE centrifugal units about 6 years, I know were the valves goes but the pipe has no valves is directly connected, will try to install the valves as you suggest and check the float valve, I have just found that I have the liquid sensor not working so maybe that's the reason for the purge won't work and not the float but will look at it anyway.
    When I changed the filters the purge unit had positive pressure

    Yeah, there's been conflicting info that purge. I haven't seen where he said it's a CH530 purge. I believe he said it's on a CVHE530 chiller. Is that a valid model number? Or is he confused between CH530 and CVHE530? Not to mention that sometimes a "drier" was changed and other times "drier cores" were changed. Regardless, your advice may prove to be best.

    It's not an Earthwise purge is a purifier purge the previous model commanded by the human interface on the chiller

    Ok Wolftre. I feel much better about your situation now. I believe you're headed in the right direction. That is a float sensor. There is no float valve. It's purpose is to send a signal to the control circuit when the liquid level is too high. Not how high, just an open or closed magnetic switch input if it is too high. A plastic, doughnut shaped float slides up and down a hollow metal shaft. A magnet on the float operates a switch located inside the hollow shaft. Sometimes that shaft can get corrosion on it and the float can stick in the upper position, which results in indication of a high liquid level even after the level has gone down. It is not that unusual for the level to fluctuate up and down, especially during purge run times while the chiller is off.

    Graham, are you sure about about that float switch? I just reviewed SB-32A and it shows the purge module with a "Liquid Level Sensor" input.

    The Chiller unit model is CVHE530 the purge is a purifier model and it has 2 replaceable dryer cores (sorry for my bad English) not a one piece disposable filter dryer

    Is the purge info read on its own small UCPII style control panel, or is read on the chiller's UCPII control panel? This will probably be the last of any questions about what purge it is. Although, I make no promises.

    The purge unit has no UCPII panel is commanded by the Chiller panel

    Ok, Wolftre, thanks. And again, I would install those valves first. I believe you will find life will get much easier around this chiller when you do. And no need to apologize for your English. It wasn't until then that I suspected English may be a second language for you.

    It's ok but now back to bussines, I have just found that the Purge suction temp sensor is not working since is reading 213F, again there is no spare part locally than I can reach to fix my purge pump so it takes me back to square one, do you think a sensor from another unit with similar resistance readings may help?
