Question: what is the flashing warning Ft?
Document: The window attachment was a bit flimsy, but works ok after some work. I set it on dehumidify, since it is only about 90 so far. It cooled my 300 sq ft bedroom down to 68! !Can't wait to see how it handles 113 Phoenix heat!
Had it for two months. It cools down the entire first floor of my townhouse, a large combined livingroom/diningroom (about 800 sq ft). Set it up in five minutes. It's bigger than I thought and more beige than the image implies, but works so well that I'll buy another for the second floor next summer. The electric bills have been minimal.
I'm using this to cool a much larger area than it should. I live in Palo Alto, so it doesn't get too hot here often, but we have days in the 90-100F range. I throw this on and it cools half my apartment during the day (with 12 ft high ceilings) and the entire place (1100 sq ft) at night when admittedly the temp drops.
True to its advertising you can easily set the unit up and have it running in under 5 minutes. It is very well packaged and the instructions are simple yet adequate. The unit works well and has easy to understand controls. No complaints on that side.I have the unit in a 250-300 sq/ft bedroom with a 3 foot vault in the ceiling (which traps a fair bit of heat).
This is a good a/c for a room where you don't want a window unit, for one reason or another. It is not quite as powerful or efficient as a window unit, but it's nice that it's portable and doesn't require the annoying installation of a window unit (though the vent pipe is annoying, as other reviewers have mentioned). It cools a large room (700 sq ft) very well. The remote control is also a nice touch.
We use ONE unit to cool down an almost 900 sq.ft. area by about ten degrees below what the outside temp is. We have a 102+ year old home that has no air ducts. We also used a couple of box fans to circulate the air while the initial cooling took place. We have not had to empty the overflow humidifier pan once, even though we live in Michigan and it's really humid in summer.
So far, this has been fantastic. Setup took about 5 minutes. Timer works perfectly. Remote is very convenient and comes with batteries. Cooling output is unbelievable; cooled our first floor within about 10 minutes.The only warning I would give is that in the box, the unit is very, very heavy. If you live alone, know that you're better off unboxing it on the porch by ripping down the side of the box.
fast cooling, no water problems, quiet, easy to install, very reliable, energy efficient, going to get a second one soon
You could opt for other installation options, and there are parts included where you could drill a hole in a wall for your vent...but then it's not exactly "portable" at that point.Do yourself a favor - if you're venting this out a window, try to install it such that you can keep (or put) a screen on the exhaust end of the hose.
You can also pick whatever temperature you want. The portable air conditioner can be used in several types of windows including sliding, double hung, and casement (you can also install it semi-permanently).For many years we've used window air conditioners to cool us off in the summer but our windows are old (they really need to be replaced) and for the past few years we've not been able to properly install window air conditioners and have suffered through the hot summers.
Answer: Due to high humidity your safety tank is full.  Move the a/c to a safe area, pull plug in back and drain it.  FT means full tank
