Summary: A few Thins too watch out for on instaling this unit. The Summer/winter dampner is a bit chessy. Not a tight fit at all, and also watch where you put the seam of the duct work. First time i fit everything, the seam was inhibiting the damper from closing all the way. And a few things about the saddle valve too save alot of hassles later with leaks.
Summary: My wife has been after me to put one of these in for quite a few years. I finally decided to get up off the wallet and go for it. Installing the unit was pretty straight forward and not real difficult. The wiring instuctions were a little confusing but other than that it went fairly smooth. My wife said it made a big difference the first night. The windows don't sweat anymore either like they did with the portable unit.
Summary: I have had this unit installed for 2 weeks already. Installing the humidifier was easier than the electric and plumbing. I keep the dial set at 5 and it seems to regulate itself just fine (outdoor air temp has been varying between 14 deg F and 43 def F and humidity level in house has ranged from 26% to ~40%). The only downside to this unit was that it requires 24V power other than that which it draws from the air handler.
Summary: I have been contemplating this for a while. Looked around and iaqsource had the best selection and information on this product. I ordered the model 500A because of the information provided. [...]. I installed it myself; and I am not that handy. It turned out great, if I do say so myself. The best part is that it works wonderfully. It has eliminated my morning dry mouth, and our skin and our house feels much better. As an added bonus, we have had to turn down the heat $$.
Summary: The installation instruction are a bit light, but one can figure it out. The wiring booklet was extremely helpful. Product is simple in design and should last a long time. Just wish the summer/winter damper sealed better and didn't let so much air through. Will probably fabricate my own and place over the opening to make summer A/C usage more efficient. Otherwise a great product - started humidifying immediately and didn't take long to reach the proper level (2000 sq.
Pros: Adjustable Settings, Easy To Clean, Easy to Install, Simple operation
