    Mcquay ALS200 Chiller

    We have a Mcquay ALS200 Chiller that we've been taking care of and wanted to make sure we aren't missing anything.

    What maintenance do you perform to keep these units in top condition?

    Water Treatment is maintained quarterly as well as checking superheat, subcooling and refrigerant charges. Condenser coils are hosed down once a year and cleaned with chemical when needed, condenser fan motors are cycled on manually to check for burnouts and contactors are checked out. We haven't had any problems with the Chiller going on 5 years now but want to make sure we are doing everything we can to maintain compressor health.

    Thanks in advance!
