Honeywell Home HE280A Whole House Humidifier, White

Would have been easy to install as replacing an older and smaller model. However, this model has the valve on the right side instead of at the bottom, interfering with the adjacent hot water heater. It could not be flipped like other manufacturer's

It has all the installation parts, however some things to keep in mind:1Tin snips are required. If you've never used them keep in mind the metal curls on one side after cutting. My advice is to drill starter holes in the corners of the square, then use the snips to go around the square in the direction where the future scrap is the side that curls. 2.a 3/4" hole drill bit is required. 3.it comes with a saddle valve (for water supply) which are easy to install but some have had leak issues with this type of valve. I used the included valve and didn't have issues. 4.I didn't think the directions were super clear for installing the pressure sensor. On the bottom of the solenoid there are 2 hose connectors. One needs to go to return/hot duct, one needs to go to supply/cold. The one for the hot duct is black and comes preinstalled/connected, the one for cold/supply needs to be connected manually via a plastic hose. This is where the 3/4" hole drill is required. You'll probably also need a small drill bit (as small as possible) to make starter holes for the sheet metal screws. Box includes needed wire and plastic wire nuts. And a transformer so you can plug it in to a standard electrical outlet.Also keep in mind there is required maintenance involved. With the yearly panel change I recommend inspecting the drain tube for blockages (and replacing as needed) , especially if u have a long horizontal run and/or hard water, or water high in sediment. I've seen these units flood basements after water/sediment built up in the drain hose.It's working well now, but the install process took me 4-8 hours. I look forward to fewer sore throats and dry skin this winter.

Tools and videos from YouTube are very important

The humidifier once installed and correctly wired works great. What looses a star is the documentation could have been written with more clarity. For one the template supplied is best described as short in width and length in the opening needed to be cut. Secondly the water valve wiring changes depending if you attach the humidifier to the return or the outlet of the furnace.

We have had such success with Amazon but unfortunately this product has been frustrating. We hired a professional to install, as it was too complicated for us. Install cost $260, which we do not mind paying if product works. We looked up possible problems and communicated with professional about low humidity levels and to date have not been able to rectify. We would return unit, but unfortunately it is attached to our hvac system. I’ve attached pics to show work done and humidity readings, as we have truly tried to make this work.Update: professional purchased a couple parts and worked with the system and it is working. Humidity levels are rising. We could not have done this without a professional.
