Not sure if this is the right area to post this question but here goes.

I had a Fujitsu mini split system installed for my two upstairs bedrooms. One heat pump outside the house and in the attic areas off of each bedroom they each have their own air handler.

I have been having problems with the units since install and just learned from the installer that they were "inadvertently" installed upside down. This caused the condensation to not drain into the pan and through the condensate line to the basement but rather drained into the emergency pan which filled and triggered the emergency kill switch. I am not sure how the inside of the unit is designed but the condensation would have also drained onto and through anything which was designed to be above the coils.

My question is this....the install company has committed to come back and correct the problem. Can the units still be used now that they have been run upside down? And also is there anything else of concern that I should be looking for at this point?

Thank you for all your help!!!

Probably okay. If damage had been done, they wouldn’t run anymore.

Post pics of the upside down units. Having a hard time understanding how the installers didn’t catch the mistake after installing the first one.

Thank you for the response.

The units are still covered with insulation and not being used now so I cant get pics. The tech who discovered the problem identified three ways he could tell they were upside down. The first was when feeling inside the unit he could tell the plastic drain pan was on the top. Then he said he observed the model/serial number sticker on the side was upside down and last he observed the brackets to hang the unit from rafters was on the bottom.

Not sure how the other guy missed it but just want to make sure that it gets fixed properly and no damage was done to the unit by running it upside down.

I’m still trying to figure out how it’s even possible?

 

[btuhack]

Wow, I thought Fujitsu was a reputable brand. : /

Are you implying they should be able to operate properly even when installed upside down?

 

[btuhack]

Are you implying...

No, I'm implying something else.

Well we had the Wall of Shame post about putting the inside units outside, so why not?
I also agree that I have to see some pics, there's enough writing on it, unless they didn't speak, read, write or ever see English.

I cannot believe that a reputable contractor could do that. Installing a wall unit upside down is inconceivable . Mini splits don’t get covered with insulation, either. There’s way too much that doesn’t make sense.
I wont’t believe it until I see pictures..

Must be cassettes installed in the ceiling and hung in between rafters. I have zero experience with them. But, if I ever put one in i'll be sure not to mount it upside down due to this post! :grin2:

They all have Ducted System!

 

[vstech]

Wow...

So... the drain line is on the TOP of the systems right now? Just... wow...

I hadn't considered ceiling cassettes but that is equally inconceivable. They would have put the discharge grille up and the metal case down in the room.

If there is an air handler, why would it be covered with insulation?

Yeah, It would be cooling the attic instead of the room. I wonder if the tech is confused by the drain opening being higher than the pan and not realizing it has a pump rather than using gravity. IDK

Without photos, I call B.S.!!!!

That has to be it.

Not a side wall horizontal mount.

Ya know...

There 'IS' a shortage of experienced and qualified labor in our industry...
Which is all the more reason to carefully vet your contractor.

OTOH... this is beginning to sound a bit like a DIY thread...
