    30rap carrier air cooled chiller

    I'm new to this site and seeking help on 30rap carrier air cooled chiller. First time working on this unit and there is no paperwork on it. I keep getting an A 201 error which I did find out by searching online might be an interlock switch. Anyone have any advice on where I can start looking for it for testing

    Your flow switch opened up for 3 seconds after initially closing. Check water flow.

    Google search Carrier 30RAP and located the controls and troubleshooting manual.
