Question: what is the operating temperature range
Document: This handy machine is really helping deal with our damp basement. It is quite quiet and has helped the humidity stay in the 50% RH range.
The Frigidaire Dehumidifier has been operating for about a month and it really does make a difference. It is positioned in a fairly large sized paneled room in the basement, about 600 square feet, and helps to make the room noticeably more comfortable and pleasant.
Still in great operating condition after 8-months. Seems to be a nice unit. My only complaint is that the fan doesn't shut off when it reaches the set dew point. Some may find this a positive for air circulation, but I wish the fan would shut off and be quiet.
I have had 2 of these units. Both worked fine for several months but both died within a year (they would run but no longer dehumidify). Nothing odd or strenuous about the conditions they were used in, just a standard basement in the 65-70 degree range. I would stay away from this brand as I have had better luck with Delongi and other brands. These were not cheap and I was very disappointed.
It needs lots of room and air circulation and even then it will raise the temperature a bit. If you keep this in a colder basement or something that might end up being a bonus feature!
*Pushes out warm air, bringing up the temperature of the room.CON'S:*Beeping on control panel is pretty loud when removing bucket, etc. Not a big deal for me.
The air that if exhausted gets pretty hot shortly after the machine turns on, but thats pretty much unavoidable with dehumidifiers. If it runs constantly it will significantly increase the temperature of a room.
This dehumidifier works very well and is not too heavy, wheels around for convenience and is attractive. My old one froze up when the basement temperature got too cold. This one works great and has been very reliable for over a year.
I purchased this to keep the humidity down in my guitar room during the winter and so far has done a great job. It quickly reduced the humidity from about 70% to 50% and holds it remarkably steady at the desired set point. I only have to run it during the day to keep the humidity within the 50% range. Overall it's surprisingly quiet but rumbles a bit on bare wood floors when the compressor turns on.
I've had it for a month using it every day. So far it's been working as advertised. Have not hooked up a hose so empty bucket twice a day, once in morning and once at night. It produces some warm air but does not raise the temperature in the basement significantly.
Answer: According to the Troubleshooting section of the instruction manual, the unit will not operate satisfactorily if the temperature is below 41º F. I would imagine that all higher temps are okay unless the unit overheats in extreme temperatures, but that was not mentioned. I hope this helps. Rx
