    Don't let Frank trick you, he's forgotten everything about compressors. How can we help you out bud?

    what are you doing with that semi-hermetic?

    Are you, as ST asked, replacing it?

    Servicing it?

    Starting it up?

    Looking at it meaningfully?

    Bench pressing it?

    Standing on it to reach the top shelf?

    You need to help us before we can help you...

    Did you ever see that commercial for a gym where all the guy says is "I pick things up and put them down"??? That reminded me of that!

    Just so you know!

    I installed some small cv rooftops today.

    I barrowed my neighbors ladder.
    She does not even know.

    sorry did not get back on the computer last night. yes it was a replacement its a 40ton unit with 3 OD fan motors that i think load or unload off the discharg line. The comp was sent to us with no oil in it i know how to get the oil in but how do you get it dialed in just right?

    It's all good, we like giving people a hard time.

    The compressor will say how much oil it holds, I'd start with half-ish of that and go from there. There are lots of ways to pull off putting oil into a system. I have always used an oil pump, I'd be interested to hear who does what.

    we used a pump as well. now there was 2 valves on the top of the compressor by the low and high pressure ports. valves that can be adjusted with adjustable wrench is that some sort of equalizer?

    Valves like a solenoid valve? Pictures?

    If I had to guess it would be unloaders.
