    RTAC Condenser cleaning

    Our building has only one chiller, a Trane RTAC 2254, this unit has two refrigerant circuits. Is there a way to shut down one circuit at a time through the CH530 controller so that I can clean one side at a time without losing all my cooling?
    I want to backwash the condensers early in the morning when it is cooler and when it will be cool enough where I might only need one circuit to cool the building. Thanks for any help.

    I do not reccomend cleaning coils with chiller running. Ciruit locked out or not.

    Shut it down and lock it out. Bad things can and do happen when you get after one of these with a water hose while still energized. Do it 3rd shift if you have to but lock it out. Good luck.

    we have first hand pics at our shop of one of these compressors blowing the peckerhead off after a start up. the fireball was 20ft up and engulfed the underside of the chiller. dont do it.

    and yes you can lock it out from the 530. your choice, your destiny, you have been informed.
    It's hard to stop a Trane. but I have made one helluva living keeping them going.

    I wouldn't have the other circuit running while I was doing the section where you have to crawl under the coils. I don't want that crap and chemicals blowing around me. But I would be ok cleaning the section where you are outside, while the other circuit is running.

    We are not allowed to work within reason under a running aircooled.
