New Motor Smell?

[Swim4Rett]

Hello, I just replaced my old Hayward motor with a new Hayward (same hp 1.5) SP1580 and replaced all the hoses and control arm on the sand filter. First time running and have had it running approx. 7 hours. Unplugged it for the night (as I am too paranoid to let it run by itself since this is first time). After about 20 minutes I noticed a smell outside. The only way I can explain the smell is that I thought someone had been shooting fireworks and it smells like the after smell of fireworks. My question is do new pumps have a certain odor to them? Motor is not hot to touch, I couldn't read the psi as I had unplugged it prior, no smoke that I can see with a flashlight, and nothing on fire. I am not a mechanical lady by nature and am significantly ignorant on diagnosing things like this. If someone could give me a checklist of sorts, I can go through the steps tomorrow during daylight.
Thank you!

So you didn't notice any smell until after the pump was off? If that's the case I would think something else was causing the smell. I've never noticed a new pump having that kind of smell.

might it just be motor oil type smell from the new pump burning off? I would think that pretty common and short lived.

Happily, the smell was gone the next morning. It just must have been (maybe) fireworks that someone near the house had set off and the smell carried on the wind. (Seeing as the 4th was just last week.)
Thanks for replying y'all!

Thanks for sharing as well, because I've heard about situations like this for a couple of times already.
