Question about Haier CPN12XH9 Portable Air Conditioner
I use this portable AC seldom, in the living room and only as a supplementary unit for my house central AC. I bought this appliance new 16 months ago and have used it only a few times. Around 60 minutes after running on AC mode, the unit shuts down because the collection tank is full. I have to drain the AC manually by removing the rubber plug on the back, evacuating the water to a short pan. This means that every 60 minutes this AC is producing 1 quarter of water. This unit is self evaporative, so I assume this should not be happening. The ambient temperature outside the house is around 100F but the interior temperature created by the house central AC is around 79F. The relative humidity is not that high. What could be causing this problem and there is a simple way of fixing it? Thanks for your help!
My unit was working fine for a couple years but now it won't evaporate. It still cools fine but it also collects about 16 ounces of water every hour and then shuts itself off until I drain it. I'm wondering it the evaporative mechanism it broken some how.

If it has an evaporation pan to "Cook Off" the moisture, it would be putting it back into the air, where it just removed it from. This will, in time cool the room but the humidity is being returned. It is possible however, that drain from the condensor to the collector is clogged, causing it to overflow. If you still have it, install the window exhaust kit that came with the unit. This will help eliminate the humidity from the room and the moisture from the unit.
As for the mols problem, Use a sprayer of choice, depending on how much area you need to spray. Mix unscented CHLORINE bleach with water, 1/2 cup bleach to 1qt water. Spray until surface is wet but it doesn't have to run down the walls, unless you need to treat them too. The chlorine bleach will kill any mold & fungus spores that it contacts. Unscented is a lot easier to live with. The regular smells like a swimming pool for a few days.

Hi. Check the drain hose and look for kinks and partial blockage. Even algae can often block these tubes. J.

Testimonial: "There was dust covering the entrance of a tube where the water used to flow and evaporate, it was right beneath where the air filter is located. Removed the dust and is working fine again. Thank you"

The drain hole (there is no plug) should be on the bottom of the drain pan, outside the house. It may be clogged or the outside part of the unit is not tilted down by 1/4", which allows it to drain properly.
Look carefully for the drain hole, as a clog may be concealing it.
Hope this helped you.
