PEX Water Supply

I only have PEX piping for my water supply in my home as it is new construction and this is all that was used. Am I unable to use the included water valve connection to connect my water supply? is there an alternative method I can use to make this connection?
Asked by: dasmikechen
You would need to use an adapter first before connecting to the water supply.

Mounting on warm air plenum

My furnace has the return air duct below the motor and the warm air plenum above it, so they are separated by a good 3 feet from each other. I think in this case I need to install the humidifier on the warm air side, but will it work as well? What is the compromise if both the bypass and the unit are mounted on the plenum? Since there is no fan, I don't see how the air will go through the unit...
Asked by: Jacs
My installation required mounting the unit on the hot air plenum and feeding the air back to the cold plenum and it worked great. Rigid duct work was used instead of the supplied flexible duct. The air in the hot plenum is being forced and will try to escape through any opening. The cold air plenum is at a lower pressure and will draw the moistened air from the unit.

does the duct opening on the side open to the left or to the right?

Asked by: Handy
The duct inlet can be reversed for left or right installation.

We just had a new central air/heat installed and both the return duct and supply plenum are made of duct-board. Is there anything special that should be done, such as backing inside the duct, to make sure the mounting is secure?
Asked by: TKcas
This is a great application question and is not the first time that it has been asked. Yes, you will have to come up with a sheet metal mounting plate that securely attaches to the duct board in such a way that there is an outer surface to attach everything as well as an inner flange to hold all mounting plates in place. There are 4 things that must be mounted to either the warm air supply or the cold air plenum depending upon your application; the plenum controller, the humidistat, the 6 in. by-pass duct connector, and the frame of the body of the humidifier.

The directions that came with the unit were older and were missing critical info of the sensor placement. I downloaded the updated directions that solved the problem. Depending on your system it is unlikely to have this work on both the heat cycle and fan only cycle. I called the product help line. The folks there were very knowledgable of their product and how to set it up.

Rated 5 out of 5 by from Hamilton Humidifier Easy to install. Only minimal sheet metal alteration required. Home Depot met all expectations and then some. I felt unit was fairly priced and customer service by Lauren was excellent. I am recommending to others.

The mfg did supply MOST missing parts in about 1 week. Then the directions were incomplete. This required another call to the mfg for instructions. After about 2 weeks of waiting and phone calls, it is finally installed. It is too early in the heating season to determine if it is working correctly.

For the most part the instructions were pretty easy, but on occasion, they were a little confusing. I had to but a 10’ duct because the one supplied was about a foot too short.

A little slow to raise moisture level in 2000 sq-ft house but eventually gets there. Installation instructions could be clearer.
