Question: Does this include the solenoid? Drip pad? Relays?
Document: The only drawback I would have to say is it doesn't contain the wire,drain hose and 1/4&#34; copper supply hose, it would have been nice to include that in the box. Also the fan on the unit is a bit loud, almost as loud as the furnace fan you can tell when the furnace is off and the unit is still running. I didn't hook it up to only run when the furnace is running and I may change that later.
We finally got this humidifier installed and we are very pleased with it. The old Model 110 no longer functioned properly with age. We would recommend this unit to all that need moisture in there forced air systems. This item was delivered on time and in excellent condition. another great Amazon.com purchase.
Very little water comes out of the drain tube when the unit is running for me, which to me means it is being evaporated into the air.Unit seems well designed, and built to last. Only complaint I have, is that when you take the unit apart to change the water plate (once per year)  it would be handy if there was a built in place to hang the front half.
Use a black marker and mark the pipe. Then measure 1" both left and right. This is where you want to make your cut. Cut the pipe in both spots so you have a 2" space between ends. Slide the sharkbite adaptor in between and press the adaptor hard in each side. It will lock in to place. Cut a 3"-5" piece of spare copper pipe and push in the middle of the adaptor.
Took me about 3 hours to install, works as expected. Things you'll need in addition are : Control wire, 1/2 Inch drain hose, 1/4 inch supply water line, Foil tape, 8 sheet metal screws, and a current sensing relay (I used one so that the unit will only come on when it reads that the blower fan is running). If your blower fan on your main unit goes out and you don't use a relay your going to just dump water down the drain.
Tin snipe. (To cut the plenum)3. 3/4" sheet metal drill bit (titanium or better)4. Sharkbite valve (connect to water line. Just push pipe in both sides((1/2" osd))5. Sharkbite 1/2" to 1/4" on/off valve6. 1/4" osd foggy plastic hose (connects to the water inlet on humidifier)7.
This unit works great! Installation is pretty strait forward and not too difficult, I installed it in about an hour. I have a 2000sq ft home and this unit has no trouble keeping humidity levels at 50%. When I first installed it the level in my home was 16% and within 2 hours it jumped to 60%!!
Then mounted the base, and screwed it in. Next, used the metal duct tape (do not use regular tape, must be the metal kind) to tape around the base. Take your time and make it look good.Next, wiring. The bottom of the base has two brown wires. Using the 18x2 thermostat wires, connect one brown wire to the common circuit on the furnace circuit. Should be labeled C.  Next, connect the other wire to the W (24v aux).
The unit is somewhat larger than expected/haven't had time to install it/appears to be very good quality/everything needed is included.
The Aprilaire products are well made and easy to install. Instructions are clear andall the parts seem to be of high quality. The unit does a good job humidifying the house.I do wish they would invent a unit that doesn't waste so much water down the drain.
