    Default Seeking TMs and Advice on Nordic ECU Install

    I just purchased two 36,000btu Nordic ECUs to cool and heat my motor pool. By my calculations I only need around 60,000btu so 72,000btu will be more than enough. I am powering it off of my MEP-005A so I will have 3 phase. I know how to wire it but I can not find the TM for it online. Does anyone have one or the pdf of one? Those that have these units, is there any advice you would give for my install?

    ECU, 36,000 BTUH, 208v, 3PH, 50/60HZ.
    CAGE CODE (17V) : 0WJE1
    ORIG. PART NUMBER (1P) : GL0343ZAADWYX01
    NSN : 4120-01-526-2397
    REFRIGERANT : R-22
    TECH MANUAL : 567-00002

    I found this posted in another thread by user RumRunner742. He said this is how he wired the same model. I will probably wire mine to a three phase plug or a three phase box.

    I have a manual but I have not scanned it in yet, the manuals last couple of pages are dyed black because of moisture. Their still ledgable.
    ECU's: 2 working, 2 dead. One is literally dead, it was shot twice.
    What info do you need, maybe I could just do a phone pic.

    I only found a parts TM for these units, never a operator TM. I wired them into my three phase panel with 30 amp breakers on each phase. Wiring order is what I posted above.

    If anyone has the operator TM for this, I will pay you money to scan and send it to me.

    30 amp on each phase? The info I found online says a max draw of 9.6kw total. Hookup won't be a problem. I was hoping for a TM in case I have one with problems. The ones I got were both marked condition A so hoping they are good.

    Someone spraypainted drained on them. Hoping they didn't drain freon! Gen sets usually have that painted on them but none of the other AC units I bought did.

    About the only wory with hooking it up, is phasing. And if I remember right, it has a phase light that comes on when its out of phase. If thats the problem, simply swap any to phases, and that should fix the problem.

    No problem at all on the hookup. I was just hoping for a TM in case one didn't work. Doesn't look like there is to much to them. Part numbers would help in the event I need something though

    Actually this picture of the hookup looks wrong to me. I haven't investigated the wiring on these, but I'm guessing that green wire should go to ground and not neutral. I don't think there is anything in these that requires 120v to need a neutral, but I'm sure it needs a ground!
