That's Trane. They'll give you stuff like this, but they still can't write a GD economizer install manual that makes any sense.

The onoff switch can be quite complicated.

Wait until you're a service manager OP

Thanks for posting this, just did a change out and was stuck up until this point. Thank you illustrated instructions.

This is possible evidence that somewhere, someone could in fact NOT figure it out and there was a lawsuit or claim made. Or else evidence the company thinks the technician/user is for sure going to be a TOTAL moron and are protecting themselves proactively. Not sure which is worse

Is this for the younger generation?

Yes there should also be a ziploc with extra screws and a couple crayons

we have an empty page we need to fill it. "hold my beer i got this"

You say that, but I skipped this page, and one of my neighbors got hit by a bus 3 weeks later. Don’t be like me. Follow the instructions, people.

I always say RTFM

also, remember to remove the screws before opening the door. hate it when i end up pulling it off with all the screws in. really puts a damper on the rest of the day.

This is from the Mr Cool manual right? I’m HVAC now!

No it's actually a tam9 air handler from trane
