    that was one of my options. I ended up just ignoring the amps after the VFD and going with the amperage before the VFD.
    Motor is running fine, amps are at RLA.

    You are correct. they maxed it out at 53 HZ to keep the motor from exceeding its RLA rating.

    I ended up not buying the fluke 289 to many beans for this tool budget year.
    I did recheck the motor amp before the VFD and it was great, rated for 6.2 actual was 6.1 ish

    I know the VFD is password protected and the manufacturer would not give us the code. I am hoping I can at least read the info from it.
    Problem is, with a motor drawing 3 times the normal...

    The VFD was at 52 HZ (was unable to bypass or set to 60 HF)

    I have some new information.

    Looks like the original assessment was incorrect.

    When the system "locks up", we were going by the dial thermometer located 1 foot below the coil on the edge of...

    work still in progress guys.
    I installed 2 air vents and they did not fix the problem.

    Cledus, I am looking into the vent / breaker you suggested. Could you tell me why I would want to introduce more air into the system with a vac breaker?

    Cledus, I have very little experience with steam. I have been in the HVAC tech for 30 years. (Warmer climates). Even tho I dont know **** about steam, I seem to be the only one so far that may have...

    I have done it many times, BBeerme. When I open the valve at the strainer it works almost as good as when we do it in conjunction with closing the hand valve coming into the air handler. Lots of...

    I removed the vac breaker a few hours ago.
    The reason I did this was of what I observed earlier today.
    The unit was heating properly when I decided to close the hand valve before the heat valve,...

    To be clear, I believe the problem is there's steam instead of water at the trap.
    the design and location of the coil + that reducing elbow leaving the coil is causing water to hang up in the coil....

    I dont recall saying it comes out in a trickle. I did mention when the hand valve before the coil is closed it takes it time coming out i think.

    I think you might be asking for something that has been tried a few times.
    You want me to ask the operator to only open the hand valve at the strainer until only steam comes out, yes?
    if so, he...

    I believe what is happening is water is stuck inside the coil and only steam is leaving the coil causing the trap to shut down. the way the operator gets it to work each morning is to close the hand...
