Am I the only one who screamed "Nooo!!!" at the computer screen when he said he was going to cut out the tab on the secondary outlet? Came here for the comments and didn't see any about it. Glad you left it alone. 😂

What a waste of time! Next time it plugs up just use a shop vac on the outside drain. This is a very common problem with mini splits. It’s a good idea to make this a spring cleaning chore every year. That overflow should be knocked out and the wires should go in between the red wire to the thermostat

Do not knock that out you will be in trouble

Hope things are operating properly for you. Just came across your video and would suggest you replace your 90 degree elbow above the trap where the humidifier drain goes down to your a/c drain with a T-fitting and have an 8 inch stand pipe installed and left open so you allow air flow for the drain to run freely. If there is no air gap left then the water draining could and probably will always backup and continue giving you problems. With the open pipe you can always pour some white vinegar into the pipe to help keep the mold from building up. Take care.

Dude. Leave you air handler alone and call a professional. You will be doing yourself a big favor.

I liked the way you explain every single thing and the way you films and do the job , because I am immigrants to US and my English is not perfect,, But your way of explaining I'd excellent .. Thank you

I think everyone will agree that having an access panel to the evaporator is a really nice feature. This should be standard on furnace/ac combos where oftentimes the only way to see/clean the ac evap is through a whole-house humidifier (remove filter) or to cut a hole in the ductwork. 😢

Also u must have enough fall to supercede the water column of the return . In layman terms the ahu has a negative pressure, if u have 2 inches of negative pressure w.c. u must have that much fall before the p trap. It's not all cut and dry .I've seen contractors make the same mistakes. If they only would not he proud and read the Manuel and code book they would be ahead of future problems. I'm not a Eisenstein, just a old mechanical contractor that god has lead through the years of a fantastic trade.

It's the 2ndary over flow drain , code requires. The secondary to run out over a widow to alert owner that main drain is clogged. A flag for the inspector. Better safe than sorry. Mechanical contractor since 1980. A proper drain means a lot u don't want the water to overflow into the ahu then to the emergency drain pan.u wNt the overflow to come out the factory secondary drain then to the em drain out out over window.

The AC drain line SHOULD BE easy to Clean Out when Properly installed 👍😅. When NOT installed Correctly then it's a Mess 😕😔

Good job

Excellent explanation! I've been curious for a while about how to wire one of these OF switches on my Goodman unit and now I know. Thank you!

That is your secondary drain ,which the plastic is part of the pan to put the water level higher which makes it the secondary

BTW 78° isn't hot .. but, I'm sure it's hotter in the attic..

This is the only video that really show how to connect this SS2, thanks.

Thanks for your help!

You need a inlet that allows you to pour white vinegar into this drain line a couple of times a year. That will keep mold from building up in your lines.

You don't want to tighten it too much because it can cause the pan to crack. You should have kept the SS2 a little loose to the point where you can actually turn in slightly. The tape will make sure it doesn't leak. Plus if water does get into the switch; to avoid vacuuming it you can just twist is down and empty it. Certified <----

Good job!

GREAT Video.
