Dometic AC Return.. how to install divider plate properly?
I have a Dometic / Duo Therm AC unit, model 630516.321. It is a heat pump model. I don't know my return model number, but I have include pics.
The AC return cover and foam filter were removed to be cleaned and not re-installed. I was going to clean or replace foam filter when I returned home (after I purchased RV from private party).
During traveling down the road, a few parts fell out of AC return box, the metal divider, white foam gasket 1/8" thick X 7" X 18". The other gasket is 1/2" X 1/2" X 15" long.
Now I do not know how they go back together! I have found some instructions on internet for similar models, but still not sure.
Anyone know how the divider plate and foam gaskets go in place?
Do I completely seal off fan box area from coil? How can it be completely sealed with just a foam gasket?
Instructions I found...Here
