Nu-air Air Exchanger Model # EL1650 Damper Motor Replacement

in THE MAIN WALL

I am replacing the damper motor on this unit. Unfortunately, I did not take a picture of the old motor set-up before I removed it.

So to get the new motor working, I need to know how the spring gets setup on the backside. Also, do I set it up with the flapper door open or closed position? Also, what position is the back toggle suppose to be in on the backside?

So many questions, hoping someone out there might have a picture to send me or can guide me?

Appreciate any help available. Thanks everyone!

    Did you ever figure this out? I'm in the exact same boat. I have a new motor, but forgot to take a picture of that damn spring.

    I suspect the motor moves the damper in one direction and the spring returns it to the origin. That's all I have, I can't find any info on the net. Have you contacted Nu-air ?

    Nu-Air won't sell me the part because I'm not a "HVAC" professional. My local HVAC company said they would fix it, but the part alone to ship in from Canada was going to be $750.

    I finally found it from a company called Impressive Climate Control (in Canada) who had the part and would sell it to me. Not real cheap, but a whole lot better than $750 + who knows what other BS charges.

    Would use these guys again without hesitation. It did take about 10-12 days to get the part because it had to go through import process (Canada —> US), and shipping was a bit high, but still reasonable for international. I think it ended up costing about $110 US after everything.

    I did monkey with it and get it back in there. Looks correct. Damper is open to the outside most of the time anyway. Only closes when it's cold, so I'll check it when the temp drops.

    Thanks for responding! Info is scarce!
