Installed the A/C...

The 13.5kBTU Carrier requires a different modification to make the drain tube adapt to it.
I will post pictures and a step-by-step procedure for doing this in my photos section.
Should anyone have any questions regarding the A/C installation, I will be happy to answer them for you.

Did it come self-panned, were you able to use the old pan, or did you have to purchase a new pan separately?

If you had to purchase a pan - what did you get and where?

Any modifications to the "hole" or to the mounting bolts?

Thanks.

Well, I had no hole. I had to use the dimensions from Airstream and then center the hole myself. I used my Roto-Zip with the diamond blade as it ate up the metal cut-off wheel too quickly.
I reinforced the front and the rear of the hole using 1.75" aluminum C-Channel. It worked BEAUTIFULLY!
The Carrier will not take the standard Airstream drain pan. It uses the "Slinger Wheel" technology that throws the condesation back at the condensor. What I did was to tap into the Carrier's drain pan by cutting a notch into the plastic. I then used a 3/8" I.D. plastic tube and a 3/8" plastic elbow and cut a 15/64" hole in the metal pan of the A/C and stuck the elbow through it. I then used a 1/2" to 3/8" rubber tubing reducer to get it to hook into the drain tube in the trailer. I caulked the crap out of everything too!
Take a look in my phoe album. I am placing some pretty good pictures of the modification in there.
I know it works because once I sat the A/C on the roof I pour water into the far end of the drain pan and it worked BEAUTIFULLY! I must have poured a quart in there at first.
I recommend that you do that test after you hook up your drain tube. It will allow you to find leaks before you button the whole unit up.
Take a look at my photos and let me know what you think!

How did you lift the a/c onto the top of the trailer?

Ken,

I made use of my brother.
We removed the shroud so we would not damage it.
The bottom of the AC has a heavy-duty gasket that is ok to slide it along the top of the trailer. Position it over the hole and VIOLA!
I used two 8-foot step ladders with the steps facing each other. I walked up a couple of them and then my brother swung in towards the other step ladder and started up. With the two of us, we got it up there in less than a minute. It just took teamwork.
Did you look at my photos?
I am going to post another one that shows the A/C sitting on the roof and you can see the two step ladders facing each other.

Yes I did see your photos - sounds like lifting onto the trailer wasn't too bad - how much does it weigh?

Ken,
They say it is 92lbs. It felt like less than that with two people though.
I am a short fat guy and my brother is just a step above that. We had no problems lifting it.
I would probably be easier if we had scaffolding and a cat-walk. No biggie though.

You HAVE to get it from Family RV Center in Florida.
They sold me the 13.5kBTU with the heat strip for $499 plus $69 for shipping.
I cannot find them that cheap ANYWHERE else.
Family RV Center's number is: 727-389-3440
I do not gain ANYTHING by you buying it from them. As a matter of fact, I have only called once since I bought mine and it was to find out where the mounting hardware was hiding, (inside the interior shroud). I was very impressed with how nice they are and how much they know about the Carrier product line.

After reading the last thread, I also bought a unit from Family RV. We ended up buying the heat pump unit. We needed to replace our a/c (an original 61 unit) since it is dying. Our furnace also is kaput. Currently, we are using a portable catalytic heater for those borderline months when we use the trailer. After talking with other folks, we decided that (since we don't plan to use it much when it's significantly freezing), getting a heat pump and an installed cat heater would be the most cost efficient way to warm up the trailer--and chill it in the summer.

We were very happy with the family RV deal, which I followed up on based on Lou's recommendation. We got the unit for $599 (it's also a 16 btu unit, iirc) plus $69 shipping. That was more than $100 cheaper than the next best price I could find. The other thing is that the salesman who answers that number is one of their leading mechanics. He really knows everything about this unit and is very patient with anwers. Finally, the $69 gets the unit shipped Fedex. That means that I could track the delivery and arrange to leave work for just a few hours to meet the package. Plus the delivery guy brought it inside for me!

And that's where it sits! I am still muddling through how to install that drain tube (fortunately, I have a tube installed for the previous a/c unit). I think I"m going to have to spend some time comparing the installation diagram with Lou's pics.

One question, Lou--do you think we could do it with just ladders & Rick and I? I just worry that we won't be able to lift the old unit off.

Mary

Lou - thanks for the tip on the a/c - I'm still have not decided what to do - I too have the original a/c on my trailer (you can see in my photos) and it appears to still be working - pretty ugly though - this is going on year number 2 to restore this trailer - should have it back on the road in late summer. I will then decide on the a/c.

As with Mary, my biggest fear is getting the old unit off and the new one on. Probably the safest bet would be to build some scaffolding.

The scaffolding was my next choice. I like to work from a stable platform. My father was an Ironworker by trade. We have the heavy-duty scaffolding right across the street at my mother's house. If my brother and I hadn't done this a couple times before, then I would have used the scaffolding. We are still kind of young and dumb so we just went up the ladders. I do recommend removing the shroud. It gives you a nice lip to grasp the metal base pan of the A/C unit. You do have to put the shwoud back on once it is on the roof. I recommend putting the shroud on BEFORE you tighten the A/C down to the roof of the trailer. That way you can step back and look at the alignment of the unit from a distance and move the A/C around until it is square with the trailer.
Has anyone found my pictures of the drain tube modification helpful? If I had to do it again, I would probably find a small piece of plastic to dam up the run-off of the condensor pan and caulk that in place. I do not recommend using a semi-permanent caulk as that will make it impossible to remove should you need to remove it.

Mary,
I sure am glad that we have become friends. I enjoy the bantering we do.
I am not sure how much your old unit weighs. If I base it upon the fact that your trailer is one day older than dirt then I would have to say that it probably weighs as much as a Pontiac!
I would be careful in the removal. Loosen it up and have Rick try to lift one end of it while it is on the roof. Let him judge the weight and see if he thinks the two of you can do it.
If need be, strip parts off of the old unit while it is still on the roof. It isn't like you are going to be using it again anyway.

Air V

Lou, Looking forward to more pics and info on the AIR V install. We are planning on swapping out the orig. a/c on our 34' excella. I did help out on a AIR V swap out on a 31' Int. we owned previously, for some reason we had to use wooden shims to level the unit and were unable to tie into the existing drain tube, so run off was running off the side of the trlr. Question: Will I be able to use my existing drain pan and run off tube without making major modifications. I'd like to take the easy way out and take it to an RV repair shop, but doing it myself, I know it's done right, besides the RV repair guys charge more than the lawyers here in Mississippi. The AIR V Unit on our old trlr was remarkably quiet and all the extra vents are a plus, Thanks much, Tom
