Question about DeLonghi Pinguino PACL90 Portable Air Conditioner

# Air exhaust hose gets extremely warm

We've had this problem from day 1. Although the unit blows cool air, the heat coming off the exhaust hose cancels out the effect and if anything makes the room warmer.
We have both hoses connected, and the other one (air inlet hose) stays cool.

The Pinguino's exhaust pipe has to be attached to the window bracket to direct the air hot air out of the room, otherwise the room can't cool properly.
The owner's manual has several troubleshooting remedies for you to try:
1)  If the window is open, close the window. 2)  If there is a heat source in the room (burner, lamp, etc.), eliminate the heat source. 3)  If the exhaust hose is detached, connect the exhaust hose.  (My recommendation is to connect the exhaust hose to the window bracket and direct the air outside.) 4)  If the air filters are clogged, clean or replace the filters.
Remedies that aren't mentioned in the manual, but you might find helpful:
1)  Make sure that there are no kinks in the hose, and that the hose either remains straight or has a gentle curve when directing it into the window bracket.
2)  A sunny window reduces the maximum power and efficiency of the unit.  Placing it in a sunny window reduces your BTUs by at least 600, which means the maximum square footage of cooled space is reduced.  Cooling a kitchen requires at least 4,000 BTUs alone, which is nearly half of the unit's BTUs.  Try to place the unit by a window that receives minimum to no direct sunlight.
Finally, stating the obvious, if the room isn't cooling, the room is too large for the unit.  The PACL90 cools up to 400sqft.  Bear in mind that the air from these portable air conditioners cannot move around corners very well, so try to set it by a window in the central part of the room.

Replace the hose with a insulated housing hose. like the ones in your attic.
though you have to buy it in 25 ft sections.
or wrap that hose in insulation.
and putting a strong fan at the end of the hose will help it **** out the heat. then you can run the hose further away.where you won't hear the additional fan.
the best is just forget the portable and sell it .
they **** energy and provide little relief.
a window or wall unit produces much better air flow and btu power.

that portable is for folks who work in a hot garage area ,not for cooling a room at all.

### My home base portable air condition blow cold air for short period I have put the temperature 16° if it blow cold air small then it will cut off and blow warm air and the room temperature is always at 30°...

Why does my portable air conditioner cool for a short period of time and then turn off?
Have you extended the exhaust hose with another? The unit can ONLY be used with the included exhaust hose (dryer type exhaust hoses will cause the unit to over heat).

How close is the unit to the wall? If the unit is only inches away from the wall and you are running the exhaust hose out a window, more than likely their exhaust hose bend is at 90 degrees which restricts air flow. In order for the unit to run more efficiently and not overheat, it should be at least 1-1/2 feet away from the wall and the exhaust hose should not exceed more then a 45 degree angle.
Are you exhausting the unit out a hole in the wall? If so, are you using a flap vent on the exterior of your home/office? The flap may be too rigid and not open continuously. The compressor is not strong enough to push the air through and therefore will only run for a short period of time before overheating and shutting off. You should take the flap off the vent and replace it with a piece of screening.

Are you venting it into a ceiling or basement? Does the ceiling or basement have ample ventilation? If the ceiling or basement does not have a way of pushing the heat from the exhaust to the outside, the unit will work for a short period of time and then eventually overheat and shut off.

### I have a whirlpool wall heat/ac unit, model ACE184XL0. All of a sudden, the heat quit working. Fan still blows, and AC still seems to work, although I can't tell if it's just pulling in cold outside air...

Dear it is a thermostat system. You can simply check it by setting temp at 30 then check either warm air is coming or cool air. at this time warm air should come. If warm air is not coming means there is a fault is realy in your pcb. It can be simply remove no need to worry.

### Brand new delonghi PAC C120e, I got everything installed easily with the unit rite next to the window, I have it turned all the way down and it still does not cool my small room at night. It seems to blow...

Since the unit is new and under warranty and hopefully you have registered it with Delonghi. Your best bet, is to contact their Customer Support Rep 800-322-3848. Doing it this way has you totally covered.

### How does the heater part of the CPN12XH9-E work? Does the hoses need to be in window still?

Yes, hose needs to connect to outdoors, since it operates as a heat pump. You'll notice cold air blowing out the exhaust when in heating mode, and hot air blowing out the exhaust in cooling mode - unit exhausts opposite of temperature you want.

### My rv air condition also has heat, the heat in it is not getting very warm. So days it will burn u out of it and some days it just blows cool air! Any suggestions. It is a dometic

Check the following if you're unit is not giving heat.
1. Keep temp setting +8 degree from your room temp 2. Keep mode in "Heat". And check the click sound in RV when you turn to heat mode. If one failed out of three your unit will not supply heat.

### Do we need to use both hoses?

You could draw the air from inside however the system works much more effeciently with 2 hoses.
The air that is drawn into the unit and heated then exhausted back outside. If you don't use the second hose all the air that is exhausted will have to be drawn in around windows and doors or othe voids in the area. This would draw in warm moist air that would then have to be cooled and dehumidified.

### Model DLE7177RM, takes about 3 hours to dry a load of clothes. Dryer is NOT overloaded.

Does the dryer heat up or is it just cool air drying the clothes ? If it does actually dry the clothes eventually then it sounds like it is heating up. First thing to check would be exhaust hose. Is warm air blowing out of it ? If warm you got heat. If cool then your heating element isn't working. It should be fairly strong current of very warm air. If weak but warm, then somewhere between lint filter and end of hose you have a blockage caused by lint buildup or hose is bent and blocking air flow. Check hose first. You can disassemble lint trap and go beyond the lint screen into metal duct within dryer and clean with a long brush and vacuum. You can also disconnect exhaust duct flexible hose at back of dryer and work through metal duct from that end too. If you notice increased air flow then it should solve problem,

### Dehumidify mode also cools

Some units do cool/dehumidify only im afraid why cant you let the unit dump its hot air into the room then it wont heat or cool the room?
