    No suction port??

    On this carrier chiller with four O6e, 2 tandem circuits and no gauge port on suction line. One of the circuits is going into low sat. alarm. Can I add refrigerant where I would add oil?

    How can you verify your chiller is low on charge without putting a guage on it? There should be a suction pressure port on the front of the compressor about the 3 o`clock position. But don`t go in thinking it`s low. Good Luck

    Is that temp or pressure! And if theres not a port on the suction service valve already there should be a plug where one can be added.
    I'm good at making things cold...You can ask my first two wives!

    If there's no gauge port on the suction line king valve, there will be a plug there where a port can be added. Do not add liquid refrigerant where the oil goes or in front of the compressor or you can damage the compressor.

    Thanks that's what I did I took the plug out and added a port. I new I could check pressure in the front but definitely not comfortable adding juice there. Thanks
