I added a thru floor/belly pan drain tube and attached it to the drain port of our de-humidifier...let it run!

Crackin' a vent 'to let in dry air' doesn't work so well here in the South East

Yeah, no need to crack a vent with a dehumidifier running.

Dznf0g,
I purchased the newair dehumidifier you mentioned and it works very well! The size is excellent for our AS and it pulls moisture our way better than chemical methods. I have noticed within a weeks time it has gotten louder be it fan and compressor. Not unbearable though.
Additionally, if I run a 750 watt electric heater while the dehumidifier is running, I notice the power to all of the outlets will shut off for a few minutes without tripping any breakers. I can reset the main or wait a few minutes and it will come back on. Is this bad tor the electrical system? Since discovering this I have been afraid to run any other heater than the furnace while the dehumidifier is running.
Advice?

Strange behavior. The dehumidifier is 190 watts only so I don't know. If the circuits are overloaded, a breaker should trip. I'm having trouble visualizing anything else. Maybe someone else has experienced this.

Would you describe the increase in noise as a plastic buzz or vibration? Some reviewers commented on increased noise due to plastic case starting to buzz. They took the case off and used tape and foam to keep the plastic parts from "itching" and they quieted right down. Mine hasn't demonstrated the increased noise yet, but I may get bored and go ahead and isolate the case.

Well I tested it with my "Kill A Watt P3" and I found that on average, while the compressor is running it is pushing 395 watts however just the fan is less than 20 watts. I used the "Kill A Watt" tester when I first got the dehumidifier and it was peaking over 700 watts so I am wondering what was going on then compared to now. I am watching it to see if it does it again or if it was simply a break-in period.

Wow! The label on the unit behind the water container says 190W. I'm gonna pull mine out and measure it. Be back shortly.

This is a pic of right after plugging it in. It actually started out at 200W but by the time I got the camera ready, it went up to 206W. Compressor driven devices have a tendency to rise in power need and consumption until full operating pressure is achieved in the freon system.

This is after about 10 minutes of running. It seemed to stabilize here. It is still running and I will only repost if it changes significantly.

I am concerned that yours is that high. It APPEARS to me there may be an obstruction in the freon line on the high side of the orifice. I am still totally unclear why you have that "brownout" scenerio. This high pressure possibility could also result in you noise issue. I'd call your vendor and explain your situation. Maybe point them here. See if you can exchange the unit.

OK, it settled in at 213 watts and never changed. I definitely think you have an obstruction ro binding motor or compressor. 700W peak and almost double while running.....something is wrong. Call the vendor ASAP. And I would unplug it.

The major cause of the problem of condensation in an Airstream appears to be answered in this thread.

Wait! You do have model AD250, right? Reason I ask is there is no "fan only" setting. If your compressor is shutting off and coming back on, that's another indication of high "head" pressure.

Yes it is the model AD250. I haven't seen it peak to 700 or even reach 400 other than that one time but you are probably right, I should unplug it. Should I contact the manufacturer or the company I purchased it from online?

You've had it such a short time, I would call the vendor for an exchange and be firm in that request. If it was a year old I'd go to the mfr.

Who is the online vendor? Never hurts to let them know that we have been discussing them on the forum and their remedy will be seen by many who have a need for a compact dehumidifier and have the means to purchase. Get my drift?

Umnn - an oil slug of the refrigerant oil having separated out in a long unused and cold dehumidifier or even refrigerator can/will trip the compressors internal temperature limit switch or throw the supply circuit breaker. The compressor section gets staggered by trying to compress or pump out the oil when it is expecting a gas - a normal operating condition if its once every year or so.

Was the dehumidifier mechanisms at 70~°F when you first powered it up? The internal freon plumbing is finely tuned to the usual household comfort temperatures for energy efficiency & economy - yes you can use it down to 35 to 40°F once its warmed up but starting it cold after letting it sit for may show just what you observed.

Good point. I assumed this occurred during the constant running during the last week(s). Did I assume incorrectly?

1) When did you note the 700 W peak and 400W run? At first startup? Or after some extended running?
2) What is your wattage during "normal" operation?
3) Is the compressor turning on and off (fan only) during normal operation at room temperature?
