along with the assistance of this forum I also used the below from a user review on the big "A"
===============================
"From: Dometic B59516.XX1C0 Brisk II Polar White Air Conditioner (15,000 BTU 410A) (Automotive)
This 15k btu air conditioner is perfect. We needed to replace both air conditioner on top of our RV (low branch incident...need I say more), and I decided to stick with what I already had brand wise. I have experience doing a lot of maintenance type work with my job, but was not sure how this would go as I had never worked on an RV system.
This turned out to be super easy, so easy in fact, that I believe anyone can do it. The hardest part was getting it on top of the RV. After that it was simple.
This item does not come with instructions, so I looked at a few blogs and articles as well as some YouTube videos before starting. Here is the basic breakdown of what you need to know if you are going to do the same thing.
First off, the only tools needed are a Philips head screw driver and a 3/8" socket or wrench. You may need a flat head screw driver as well, but having done two in a day, I didn't.
Secondly, the only thing this comes with is the roof top unit and the gasket. That's it. So if this is a new install, you will need the electrical connection kit and the ceiling kit of your choice.
Back to what I had to do. First thing is to remove the filter/ceiling unit cover using a screwdriver. Once the cover is off, you will see the ceiling template (metal bracket that holds the whole thing in place) as well as the electrical connection box. Make sure the power is off before moving on...got it, ok. Ok the outside of the box is a white plug with six wires...simply squeeze the sides and pull off...its that easy. Now, you should see two black wires going up into the a/c on the return side (filtered side), reach up and carefully pull out the freeze control sensor off of the evaporator coils (looks like a radiator). Make note of where it was placed as you will place it in the same spot on the new one.
The next step requires the 3/8" socket/ratchet. There are four bolts that hold the unit in place along the outer edges of this metal frame. Loosen them all up and remove them. At this point the metal frame will want to hang on all the wires. I just let it hang personally, lowering it slow enough so as not to damage anything.
At this point you can go up too and remove the a/c unit. It might stick to the roof as it's probably been there a while, but it's no longer connected. Be careful, the a/c unit is 80-85 pounds which while not outrageously heavy, due to its shape and size is awkward and can cause a back injury.
So now I'll skip ahead and assume you've moved the old unit out of the way and have the new one on the roof. Before moving the new unit completely into position I would first make sure to clean the area the old unit was in. Also do not drag it around and slide it too much as you could damage the gasket. Try to move it as close as you can to the right position, with the gasket being an not a 1" thick I was able to look underneath and get pretty close just by seeing the line of the old a/c gasket on the roof. Once your satisfied, go back down below.
Looking up into the hole you want to see that the unit is centered pretty well. From down here you can actually reach up and push/slide it around a little to get it just right, making sure that the gasket will seal all around. Once you're satisfied with its placement, now comes the easy part. Grab those 4 long bolts and your 3/8" socket again and put the ceiling template back in place. Tighten them in a cross pattern a little at a time, the manual (I found it online) says to tighten to 40-50 inch pounds (not ft pounds). This means 3-4 ft lbs which you probably don't have a torque wrench that will work at that low a value. Let's just say it's not super tight. You can crush your roof as well as bind the unit if you over tighten. I will say that the 1" gasket will compress down to between 1/2-3/4" when tightened properly (if you do get any leaks you can tighten a little more, but if you over tighten you won't be able to and you will have big issues).
Moving on. Once the a/c is as tight as it needs to be, place the freeze control sensor on to the new unit's coils, reach inside the new unit and pull out the power plug and plug it into the electrical box.
At this point I would turn power back on to test the unit. If you turn it on and everything sounds right you're good to go, simply reattach the ceiling unit/filter housing and relax. Congratulate yourself on a job well done!"
