Sup Guys new to the forum from Tomball TX. Wondering if anyone else has installed their 2nd AC lately? I have allready purchased the Gateway, relay control and mount kit. just looking for a good deal on the actual Dometic AC.

I have read and re read the instructions and seem like I should be able to get it done. Just wondering if anyone has done it and if they ran into any issues that may have not been in the written info above and maybe have pictures or videos?

Thanks!!

Sup guys, just wanted to give an update.

I did in fact install my second AC about 3 weeks ago, I was planning to take pics of it all but had been raining and caught a break in the weather and went to town and totally forgot about pics while I was in the install zone. I opted for the 15k version just due to summers in Texas get a little wild and not crazy much more $. So I got the Relay controller (this included the long mounting screws which I found odd to be included here and not the mounting kit), Gateway (included temp wire sensor which RV has already pre-wired), mounting Kit and AC (ill post at the end list of the p/n’s I used which are basically the same as listed up top, along where I bought from and price for others to see and compare). Laid everything out in the living room got familiar with it. The gateway had some useful info too. The instruction’s laid out by Chief in this thread are spot on!!!. After I got familiar with the equipment, went in to the RV pulled the wires down from bedroom along with pulling down the existing rear AC setup. Compared it all with of the instructions & everything made sense, so very grateful for his input and attention to detail while spelling all this out. I did use a decent amount of Ac alluminum pooky tape or whatever its called to seall all around the ducts in the vent area.

Only issue besides the norm of taking off the existing sealant from the vent and getting the AC on the roof by myself ( was a little sketchy) was my in-command APP. After install, I fired everything up and all worked as it should from the touch screen and was very happy about that. Issue was my phone app along with my wifes would connect to the RV the quickly disconnect and close the app. Did it for 2 days. I contacted ASA (in command peeps) they suggested to fist before anything else update the software in the RV. So I got a USB, downloaded the 3 updates from their website and followed the instruction provided and that fixed it!... So far I have only been on one weekend trip with 0 issues and worked great! (fingers crossed).

Parts list, price and from where purchased (prices inc. shipping)
Ac bought from PPL
Duo-Therm Brisk Air II Air Conditioner-15,000 Btu, Black p/n - B59516.XX1J0 ($724.17)
The items below bought from Ebay
Dometic Relay Controller p/n-3313191.00 ($64.52)
Dometic Gateway p/n-3316945.040 ($86.60)
Dometic ducted mount kit p/n- ($47.63)

Total cost was $922.92 for 15K ac, dealer quoted me 2280 for 13.5K ac. So glad I found this and happy with the outcome.

Paying retail "dealer prices" typically hurts. It's a great savings if you have the ability and knowledge to DIY it.

On the newer Dometic roof AC's, with the styrofoam cover over the evaporator area, how does that styrofoam come off? Just lift, pull, cut around the base? It appeared to be maybe glued down? Not sure. Then if so, how to attach back afterward? Thx Kevin

Morning Bud,

I am not sure I did not remove the cover at all. I installed the freeze sensor through the underside once i had all ready installed the ac on the roof. placed it and the same spot as the existing rear AC.

Pics Available

Should anyone like them, the pics referenced in the original post can be found here:

The OP still had them and messaged them to me. They are in no particular order but we found them useful.

We installed our 2nd unit today. The entire project from start to finish took just over 4 hours and the unit fired up without issue on the InCommand system. A 1" hole saw worked well cutting the hole through the wood support - I had no sheet metal to contend with. Using a fish tape (or any kind of stiff wire) worked great bringing the wires through to the new location.

A couple of things we observed that differed from the instructions in the original post:

1. When looking at our existing gateway, we did not have the jumper connector that was to be removed and installed on the new gateway. Instead, we had a green/yellow wire with connector already in the slot. We left it intact. I'm am really glad we didn't have the jumper there to remove as there was about a 3" blob of sealant overflow that got on the gateway, essentially sealing the connector in place.

2. We had an unmentioned wire in the bundle we removed from the white box and moved to the new AC location. It was a splittable wire - black on one lead, dark gray on the other. We just left it alone.

3. Minor, but just in case you encounter it - our looped wire (the one that you need to cut in half) was red and white and not green and white.

Thanks for getting these pics for us.

Side question... Is the green and white wire just a 12 power line?... I just want to install a basic 12v fan right now and the vent I have has no fan so I need to get 12v from somewhere...

Also is the green the positive or negative?

KR, I hope someone can tell us the answer to this question because I was wondering the same. I can tell you though, that of the two white wires, the one with a color stripe is usually the positive line.

As total novices, we basically followed along with the original instructions when we did our install and everything worked out. Unfortunately that also means we can't shed any light on the actual purpose of that looped wire.

Sorry if this is a dumb suggestion, as again we are just learning, but could you snip it and check it with a multimeter? The OP did state in the original text that this wire 'powers things down the line...'

With a little more research I found a green/white wire should be a 12v circuit (Hopefully not a comm cable for the AC) so Iíll try to confirm with a voltage meter...
