Attwood AC install
So started the new ac install today. Was just me so I was limited in what I could do. First got up and pressure cleaned to roof, lifting up some of the solar panels (they are removable and can be tilted) and what  a bunch of junk under there....

After watching the installation of my units, I would recommend leaving the "shells" off the units while they are being moved up on the roof and into position.  Leaving covers off makes them less bulky, allows more places to grab on to, and...

Same here. Just a minus sign instead. Really interested in the Atwood install as I'll be doing mine when we get back from our next trip.

When I installed my units I placed a ladder at a shallow angle and pushed the A/C units a head of me up the ladder, Not too bad a job.

 "After that they easily pushed up, but I left them on till tomorrow when I can get my 2 boys to help."

When I...

Lon,
  I was thinking about doing it that way too. One question: How did you get it over the top of the ladder without kind of dumping it onto the roof? I was thinking I might pull it up instead...

Okay so a acs are on the roof now and I'm hooking up wiring on the front one. Got the 12 volt and the 120 volt wiring hooked up no problem but now I'm coming to the thermostat. If I use the Atwood thermostat which I want to do there is a miss...

So how we got them down? I slid them down a ladder with a rope attached to it. Those were the old penguin low profile ones I believe. to get the new ones out we did reverse we tied a rope around the AC unit and slid up the ladder we put a box...

When I replaced the rear AC on our '89 I did it somewhat similar. I used my 14' extension ladder fully extended and leaning so just the top end was slightly above the edge of the roof. I moved my 8' stepladder up close to the coach and under the...

Didn't measure it but comparing it to the dometic unit it is a bit smaller and the hole  doesn't line up exactly  to the hole...

Putting in the easy start was not to bad on this unit. There is a pdf for the attwood on their site.
I put the unit on the other side, ran the wire through the unit, slipped it in the same hole the compressor wire bundle went through, and attached...

I should mention that I was chasing a leak somewhere up top this spring. So one of the things I did was replace the foam gaskets under both ACs. But, being paranoid because of my so far unlocated leak, I put the foam gaskets with the "sticky"...

So I removed the dometic thermostat and put in the attwood. I spliced the wires together. Now I get the fan in the dash air running but not the AC fan, although it did come on once.
HELP?
Now I remember that the thermostat controlled both front...

David I swapped both out as well. I took pics of both before I disconnected them but now am scratching my head about it. Didn't think of the aqua hot. When I select fan only that fan comes on, not the ac unit. I haven't hooked up the rear yet....
