A/C drain???

[8181]

I have recently acquired a 1981 Excella with a Coleman A/C.
When I had it out last week, I noticed that the A/C condensation was trickling down the side of the unit.
This does not seem correct. I looked in both the Owner's Manual and the Shop Manual, and I see no discussion.

Is it supposed to drain into one of the holding tanks or is there a line in the wall to drain onto the ground? If so, where should I look for it.

Any hints on cleaning the drain would be appreciated.
Thanks.

I think that might be a normal condition for your trailer. If I'm not mistaken, A/S's were never equipped from the factory with Coleman units, and the retrofitted one's don't have any sort of drain tube to connect to, so they just drip down the side of the trailer.
If your trailer was factory equipped, (and the coleman is a replacement, rather than a retro-fit) there is a drain tube that runs between the walls from the a/c unit's location to the belly of the trailer, where it dripps the condensate on the ground.

In some years Colemans were OEM, but Airstream still put them in a drain pan and used the hidden drain. You should have a black hose that hangs out of the road side of the trailer just in front of the wheels. This is where the drain water would come out if the tube was connected to a pan.

You can order a pan from Airstream for an AC but the only one available is for a Duo Therm Penguin. I belive Inland RV was designing some for other models but you would have to ask.

I've seen serveral units that leak down the side of the trailer. They did not seem to be Penguin units. FWIW....

Many thanks to all for the prompt responses to my query.
I found the black tube in front of the tires. Now I have to go topside and see if it has been plugged by the nasty mud-dobbers we have down here in Texas.
