How to remove rear A/C from ducted international

[gmattingly]

Help! Does anyone know how the Dometic Penguin II's are attached to a ducted International Serenity and how to remove it? Our 2016 rear unit won't cool or heat and after doing all the checkouts and reading other posts, we bit the bullet and bought a new unit to replace the defective one (6 months past warranty). Plan to replace myself, but at a bit of a loss as to how it is attached. Thanks for any help!

It is easy to remove. On your ducted system remove both air intakes. The AC is held/clamped in place with 4 long bolts that go through a cast meter bracket inside the trailer and into the metal frame on the AC unit.

Here’s a pic of mine that is not ducted. Yours will have to be removed from inside through the air intake.

There should be a compressed foam gasket between the ac and your rooftop. I don't think the manufacturers recommend caulk or seal, but my Airstream class b ac was installed with caulk.

If no caulk, the gasket could still be stuck from compression. So it may not lift free after the bolts are removed. It's going to be up to your how to get the ac pushed up and freed so it can be removed.

I replaced my ac with a unit by the same manufacturer (newer model) and it was basically plug & play. Youtube was very helpful.

Good luck.

Thanks all. Got the unit replaced, used the drip cups from the unit I was replacing, all was pretty straight forward. Hindsight being 20/20, would probably have ordered an additional gasket kit and put it on, as the cups can press into the roof if you torque bolts to the recommended 50" #'s. The factory installed unit wasn't torqued down that much and it didn't use an additional gasket. We've got cool air again in the rear!
