Cool-Cat Heat Pump

I have an a-frame Flagstaff 19qbhw and have had it out for about 5 trips now in hot humid Alabama. Does anyone know where the ac unit is supposed to actually drain the condensation from? Last time out using it in ac mode I noticed the Cool-cat has two small clear hoses coming out the side of the cover for the unit near the bottom and thought they were the drains for the system. Water was draining from under the unit and not the two hoses so I thought the drain tubes on the side might be stopped up and got under the trailer to check it out. Found a round 2" screened drain in the floor pan. This weekend I was using the unit again and noticed water from the ac unit seeping out at floor level between the cover for the unit and the wall of the camper. Nothing at all out of the two hoses or the 2" drain in the floor. I raised the side of the camper a little and the water started draining from the screened hole under the camper. Does anyone out there know what the two small clear hoses on the side of the unit are for? I called the dealer and they were not sure what they are for, should they be draining or not when in AC mode?

Thanks.

Yes, the tubes are for draining condensation from the coolcat. IME, they work best if the door side of the camper is slightly higher than the service side. So when you level, let the bubble be slightly toward the door side. If they are not draining when sloped properly, the tubes or the pan may have a problem. You could clear a blockage in the tubes by carefully running a wire up each one. Mine drain when setup as described above, so I don't have any specific maintenance experience.

Thanks Poonell

Thanks, I will probably take off the grill and do a visual to make sure everything is attached ok and sealer was used on the fittings.

If it is any consolation, I am in Central Florida, humidity is horrible and I ran my A/C for 8 hours today 11 am till dark, was 94 today, very slightly tilted trailer as described by Poonell. Now that it is dark, I took flashlight to see pan better. There is minimal moisture in the pan/barely enough to dampen a tissue if wiped. The 3 " drain tubes are set from the grill to the outer edge of the 1/2 in deep drain pan. Unless pan gets full, there will be no drainage outside the camper from those tubes. Something apparently is helping water evaporate. No sign of wet under the bed compartment or under the camper. Set at 23-25, the camper was quite chilly all day.

That would be interesting to know.

As a fellow denizen of the humid climes, I fixed that for ya, DobeFanatic! Call it a humiditarian gesture.

Never ever heard of a cool cat are they the manufacture of them? curious just would like to know, and here I thought I have heard of every brand out there. Never mind I google it, They are made by dometic, there's your problem to start with.

Today I was slow to turn on the A/C, up to 92 outside at 1 pm, so checked frig temp (on elec), it had risen from 40 to 54 on my remote dial with AC off. I am using a small fan inside to distribute cold air-2 D batteries ) So checked AC after 10 minutes, bunches of water running out the rear lower corner of grill, none from tube next to it, flashlight reflects a good amount of water laying in the pan. Sounds like the drains are just cosmetic.

as for the ac ... sleep at the passenger side, and lean the trailer 2 degrees towards the cool cat unit .. it will have no problems draining .. or conversely, dump the nose down the same amount ... and you will loose any issues ..

as for the fridge .. ramp it up ..

Strange thing is that after the initial AC startup drip today ( it was another hot/humid day ), it stopped dripping entirely, and I do have it slightly tilted to AC side. Yesterday, first day I used the AC, no drips at all though it was cooling down the camper nicely, go figure! I think the heat being blown out of the vent is actually evaporating some of the water in the pan.
I do wonder if the tilt, though minimal is affecting the frig. I have bumped it up from 3 to 5 several hours ago and it is barely responding, still 48, vs 54 degrees at noon today. Just took the tilt out and left it at 5 for overnight, low tonight will be 80ish.
