Dometic B59516.XX1C0 Brisk II Polar White Air Conditioner (15,000 BTU 410A)

I have a 2017 Forest River Vibe with a rooftop a/c unit that had gone out. After much research I found this one on Amazon had the best price and fastest shipping, so I ordered it. The unit arrived within 4 days, fortunately, and without any damage. The unit comes ready to install, with the seal already attached to the base of the unit, so all you need to do is remove the 4 bolts holding in the old unit, unplug the wire connector from the interior ceiling air return or control unit, install the freeze sensor (see below) put the new unit in place, plug it in, bolt it down, and turn it on. It's all very simple.Unfortunately there are no installation instructions provided with the unit, so before uninstalling the old unit, I recommend using a sharpie or nail polish to mark the bolt threads where they enter the a/c unit so you'll know just how far to screw them in when installing the new unit. You may want to clean the roof prior to installing the new unit, to make sure you don't get any dirt, leaves, or other debris trapped between the roof and the seal, as this could lead to leaks. Also, be sure to rotate the fan on the new unit and make sure no packing material is lodged in it. We had a small piece of foam in ours which made it vibrate when running. We then removed the foam piece to find that it still vibrated, though not nearly as much. This was due to the fan being slightly misshapen and unbalanced, but after running for a few days the wobble is completely gone.As for noise level, the new unit just as quiet/noisy as the old unit, but it cools way better. Before our old unit quit working, we'd have to put the thermostat at 72 or lower to notice any cooling whatsoever. However, with the new unit, we keep it between 75 and 78 depending on the time of day, and that keeps the RV plenty chilly, almost to the point of needing to wear a light jacket.The new unit seems to be slightly smaller than the old one, and also seems to weighs less, but looks identical. Also, when we started up the new unit, our Dometic thermostat showed and E5 error code. After looking this up on the web, I found that it was an "Open circuit or out of range freeze sensor". Come to find out there was a white wire which we unplugged when removing the old unit. After investigating, the wire is actually a freeze sensor with one end which plugs into the control unit (the part on the ceiling), and the other end is a sensor which was simply pushed in between the fins on the evaporator coil. I recommend watching a video called "How to property install a coil sensor" on YouTube before you install this. Also, it's easier to install this before you bolt down the new unit.One difference between our old unit and this new one is that on this unit, the fan seems to run all the time, literally non-stop, and only the compressor starts and stops as needed to maintain the temperature. On our old unit, the entire unit would shut down when needed. One reason could be that I think this new unit is designed to be used with the control panel on the ceiling, and not with a thermostat, so that would explain why.As for getting these units on and off the roof of your RV, I used some tie-down straps which I ordered here on Amazon a while back. I simply weaved the strap in and out of the holes in the base of the a/c unit, and hauled it up while my son guided it up the ladder (also from Amazon) from below. This was a very fast, safe, and easy way to transfer these units, just make sure you've got good footing before doing so.Due to the ease of installation, as well as the item price, and fast shipping, I give this item 5 stars.If you found this review helpful, please leave a helpful vote. Thank you :)

We are so glad that we got the 15,000 BTU air conditioner to replace our old air conditioner which was 13,500 BTU. It works really well, cooling our 30 Ft Fifth Wheel. It's quieter then our old one but not as quiet as we would like. We had someone install it we didn't do it our self. Installation went well. We had some problems getting it delivered to us through FEDEX and had to call FEDEX ourselves to solve the problem with them. No fault to the Seller. The seller contacted us to be sure we received the wedelivery.

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!

good price and it works well. I was hoping it would be quieter than my old unit, but no luck..easy install if you are replacing old unit and have the interior assembly already in place.Has the rubber seal - so no additional sealants or gaskets needed.You get what you see on the picture - no screws, no instructions.You must get a DOMETIC ceiling assembly for either ducted or ductless installation to make it work if you don't have that in your RV already or are adding a second unit. If that is the case - shop around for a complete unit - may be cheaper.Here is what I got to supplement:https://smile.amazon.com/dp/B00HJQ86UO/ref=cm_cr_ryp_prd_ttl_sol_4Dometic installation and configuration instructions are very hard to get.
