Aprilaire 560 Install Questions
Howdie all, I am new to this forum.
A friend of mine gave me an older model Aprilaire 560 Humidifier, the price I couldn't beat, it was FREE.
I checked it over electrically, the 24 vac transformer, the water inlet valve and the humidistat are all in working condition. I can get the water valve to cycle turning the humidistat up and down. So I'm ready to install it on my furnance. If it does what I expect, I may someday upgrade to an automatic humidistat with an outdoor sensor.
I need to get some replacement water panels, a saddle valve and a new inlet screen filter and I'll be ready.
Anyway, before I start cutting ductwork, my first question, is what side should the unit be mounted, supply or return? Is there an advantage to either one, and if so, why ?
I read thru the owners manual, but it doesn't exactly explain the advantages or disadvantages of which side to mount it.
I have a Lennox, G26 furnace with a\c. Just above heat chamber, and on the right side, there are two, 2 inch PVC pipes ( outside air, intake and exhaust ) in the way of making this an easy install. I can cut and replumb these if necessary to mount the humidifier on the supply side. Otherwise, I may have to install the bypass ductwork on that side.
I can also post pics if that will help clarify my install.
