Rated 5.0 out of 5.0 by Darrel Great Product. I mounted it to the flex duct return.
This is a great product. I read the reviews online and discovered the Honeywell model has issues, so I went with Hamilton. Very pleased and zero regrets. I have a 1,600 sq. ft. house and this unit can make the windows drip with condensation (I actually have to turn it down). No moving parts (except the water solenoid), no slimy drum to clean out, and best of all no humidifiers to refill.
See the pictures, attached. The directions say it can be mounted to either the return or supply ducts at the furnace. I have a flex duct return, so I wanted the main body of the humidifier mounted to the solid surface of the supply duct. The directions did not describe this scenario, so I improvised. I hope the attached pictures and drawings help someone else in the same boat I was. I did have to install a 110VAC outlet for the power. However, I already had an existing drain (for AC condensation), for the drain tube.
The unit works beautifully and no more dry skin. Great job Hamilton!!!

Rated 5.0 out of 5.0 by DIYGUY614 Great Humidifier for the Price and Everything Needed for a Typical Installation is Included
I have owned a 12HF for several years and have had good luck with my unit and recommended it to a neighbor that had mentioned their house gets dry in the winter. I did my own installation, so I offered to help them once they received their humidifier and a little over 2 hours later they were set.
What I like about this unit compared to other brands is that it comes with everything needed for typical applications in one box and it has a plug-in transformer so no hardwiring is involved. Plus, it uses a lot less water than most other brands out there; the water valve on most flow through style units is completely open when there is a call for humidity, but this unit adds water in pulsed intervals.
Lastly, maintenance is very low. I just put in a new evaporator pad at the beginning of each season and wipe out the shallow drain pan area to remove any mineral build-up.

Rated 4.0 out of 5.0 by animalguy A quality product
This humidifier works as expected and installed relatively easily with basic HVAC tools and knowledge. I didn't run across the leaking problem that others had mentioned. I did meticulously make sure the unit was installed level. The supplied 6" duct was long enough for my application. I connected the power source to my furnace circuit board rather than an AC outlet. I would have given 5 stars, but product has only been in service two weeks. I can't comment on long term use. I have noticed house feels more comfortable at lower set temps.

Rated 3.0 out of 5.0 by GJHeis Finally installed...not easy. I will update the performance
I bought this product because it was advertised and the reviews stated the installation was simple. It took me about 4 hours to install it. Admittedly, most of this was due to my lack of knowledge, but a LOT of it was due to the poor installation instructions that came with the product. In particular, there was no information available on how to wire the system. No color coded, or keyed electrical connection. I called the company; closed on Saturday. I scoured the interned....nothing. I decided to just give it my best guess - IT WORKED! I assume the polarity doesn't really matter.
There are many other gaps in the instructions that require some patience and careful reading. A few hints:
-Buy good tools to cut the duct work. This was the most time consuming and difficult part (except reading the instruction and researching).
-You have to take the humidistat apart to determine which connection is "COM" and which is "NO".
-MAKE SURE you buy extra 6" flex duct. The amount supplied is not sufficient.
-You will need some extra wire for almost any installation.
-You will need extra wire nuts (2)
-You will need duct tape
-You will need a 3/4 wrench and a 5/8 wrench (instructions didn't say what size)
-The wires that run between the controller and the valve don't seem to matter which wire goes where - or I just go lucky....not sure.
-The hole in the duct work for the humidistat must be completely opened up to fit the mount. Go slow and make sure you understand what you are doing before cutting - the instructions suck.
It is a warm and humid day, so I can't say if it works properly. It test mode, it seems to work. I will update the review in the coming months to rate the performance. I am worried the installation may affect the performance. Again, the instructions need to be more complete to help the average home owner.

I installed the product about three weeks ago. At current it is working as expected. Installation was an easy task. It only took me a few hours to install. I'm a bit of a perfectionist so it took a little longer than it could of. Plus I hard wired the unit to the furnace so that I didn't have to install an extra plug for the unit and the drain pump. If you have access to a floor drain you won't need a pump. My last humidifier lasted for ten years so the jury is out on the longevity of this unit.

Instructions could be a little more detailed other then that it is a nice unit. Had help installing it and the person helping said they liked this one over the one they had installed and is going to switch.

While the instructions were not that clear, the unit was relatively easy to install. It worked fine the first time and has been doing its job now for a couple weeks. It is well constructed and does use less water than the free flowing humidifier I had on my last house. If not for the outdated or misprinted instructions I would have given it 5 stars. I consider myself fairly handy and it took me 4 hours to install.

I purchased this humidifier to replace an older Lasko unit that had failed after 10 years. This unit had a slightly larger footprint and installed easily. I already had the power, water, and drain setup so install was a snap. It comes with everything necessary down to the saddle valve for supply and hose to connect to the drain. It makes an odd sound when the solenoid valve opens but other than that is completely quiet. It also includes a damper for tool free seasonal transitions. I purchased an additional wick to save searching for one later. The difference in the house is amazing. Cats are much happier.
