    carrier 30gh flotronic 1990

    Hello gents
    ,hope all is well. I need to know firstly is it possible to convert old carrier 30gh flotronic to txv? and if so how to go about it. the 30gt has a setpoint for txv or exv , the 30gh doesnt appear to . I read somewhere about a kit for retro, eprom required? Site wants to convert to 407c/poe, 1990 chiller, I guess im also wondering if its possible to install txv and lls and ignore exv modules? or would that bring up alarms not seeing the windings? other option upgrade exv and drivers? that maybe quite pricey, thanks for input! stan

    looking through alarm list it looks like failure to pump down will also be an issue, not sure where that signal could be picked up from...

    What type of control panel does this chiller have? How about a model number?
    UA 100

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    I would think you will be ok I early on they made our 30GTN's in R-22 and the alternative at the time was R-134a but that was a few years ago.

    I have not seen a 407c conversion here as of yet.

    Good Luck let us know how it goes.

    ok I will, pt relationship is close enough , if only they had parameters lik 30gt and 30gb option of exv/txv I would put 407c txvs in w LLsolenoids.
    fingers crossed , less than 2 years life left for this chiller stan

    You can change the refrigerant setting in the factory and service configuration to R407C from R22
