Is there a drain for the AC?

I thought I read somewhere about a drain for the AC unit. Does this exist and if so would it be in a mote under the unit or does the AC unit drain pan feed directly into this drain some how?

On at least the newer models, there is a drain tube in the ceiling/wall of the trailer and it exits at the bottom, draining the water on the ground.

True of the older models too. That's exactly how our '72 drains.

There's been a drain tube in most models since about the mid 1960's or so. Now, whether your aftermarket a/c will hook up to it is another question.

Yes but where is the drain and how do I clean it out. I am sure it is there but how do I get to it to clean it. I am going to replace the shroud so this is the perfect time to do it. I believe the unit is the original 1981 Coleman unit. A Mach 3 it is called.

Perry,
The AC drain on my '72 exits in the street side wheel well. When I was replacing the rear floor, I found that the tube had shrunk and was no longer protruding through the wheel well.

I know it can be done from the top, should be able to find it with the shroud off, 'bout a 3/8" black tube, but all I do is set the compressor regulator at 20psi and blow thru the drain at the outlet under the streetside middle. Usually at spring get ready and mid-season.

As an aside...although it's not a huge big deal, I just hate to see water from the AC condensation dripping on the tire... so I bought a 2' length of clear plastic hose that slips over the drain tube so I can direct the drip away from the tire. I covered the end of the tube with a small piece of an old nylon stocking and secured it with a hose camp so no critters can crawl up inside it. I periodically flush and clean that hose out because over time the nylon accumulates scum, etc.

Anyone have a photo of where it comes out on top? I know mine is not working. I am going to be up there anyway I thought I would take a look at the top end of the tube so I know that is at least hooked up.

The drain line is between the inner and outer skins. This is how it looked on my original Armstrong unit.

Ok cool so I can access it from the inside if I take the inside stuff off. That helps a lot.

Thanks

my drain did not work anymore,every time i turned on the ac it would start dripping inside,,did not want to take everything apart so i put in a new plastic pipe,re rooted it towards the door,over the sink and down( in between the wall)and since it works just fine and drains very well...it is sort of a home remedy...professionals would probably raise a eyebrow!!!!

Of course, this has happened before, and to many members. I like the contents of this thread, and in particular, post #10.

Your mileage may vary...

It is not uncommon for certain insects to find one end or the other of that tube and make it their home. If you can get to either end and poke a suitable probe into the tube, you may break loose the clog and then as previously suggested, use some low pressure air to blow it out.
