Now which is the correct installation of an Aprilaire 600 series by-pass humidifier? Can the unit mounted to the supply or return duct.

It says in the manual that it can be installed in either. I installed mine in the return with the bypass to the supply because of space considerations. Been working fine this winter.

The Aprilaire 600M can actually be mounted on either the supply or return duct whichever is the most convenient installation.
2035223
Yes, per the instructions you can install it either way so long as the bypass goes to the opposite plenum. I installed mine on the cold air (return) side with the bypass going to the hot-air side, just above the furnace blower.
2035224
I would think it would need to be mounted to the supply duct so that it blows through the house with the rest of the hot air from the furnace.

My furnace installer who has experience with these units says either will work, but the return air is preferred for greater efficiency since the manual unit (mine) only starts when the blower motor turns on. I also found I had to set the humidity control at a higher rate than the manual specified to create more humidification because of the previous statement.

Yes..the unit can be mounted to supply or return side. Like others had mentioned, it's a matter of space convenience for you to mount it for easy access.

If you use the schematic listed for "Automatic" operation (i.e. intercept the "G" wire between the thermostat and the furnace, putting the new humidistat in between) then this unit will be able to use the furnace blower without firing the furnace. Tapping into the hot water supply (instead of cold) is recommended if you use this feature. My 700 is installed this way and works very well in this configuration.

It isn't a manufacturer-specific product, so while I can't say for sure, I do not see why it would be a problem. Most humidifiers are built fairly similarly.

What is the warranty for my Aprilaire humidifier? Aprilaire humidifiers carry a 5-year limited warranty on parts from the date of installation, when installed by a licensed HVAC installer. If not, the warranty is void. Found the above on Aprilaire website.

From the installation manual."2.Humidifieris supplied with bypass duct connection on left. For right side bypass, swap location of drain spud (9) and cap (10). Twist to remove spud and cap."

I don't think it will make any difference as long as it is installed on the return duct , in my case , I installed the humidistat about 5 feet from the main unit which is the aprilaire 700 and it's been working like a charm for me specially when I used that outdoor sensor that came with the unit . I hope I was helpfull

No, the fan motor is 120VAC and the humidifier controller and water valve are 24VAC. You will damage them. Without knowing exactly what you have it is hard to tell you how to hook this up. The 500 control box has terminals that will match your home thermostat terminals and your furnace terminals. Terminal R-is red wire, Terminal W is a white wire. Terminal G is a green wire. And terminal Y is a yellow wire. Match the terminals from your thermostat or furnace with your Aprilaire controller. the wire can be purchased on line or from your local building supply like Home Depot. Both the Aprilaire humidifier and the controller come with wiring instructions. However if you have a late model high efficiency furnace it will have a humidity terminal marked HUM. If this is the case connect the Aprilaire controller G terminal to the humidity terminal. No other wires should be on the Aprilaire controller G terminal or the HUM terminal of the furnace. If you connect it incorrectly you do run the risk of damaging the controller, your furnace or both. I have 30 years experience in control circuits that helped me hook this up. Better to ask a professional for help if you have any confusion. Followup after I looked at my furnace connections. I made one mistake for the HUM terminal on high efficiency furnaces. You need to connect W terminal of humidity controller to HUM of furnace not G. FYI on furnace connections R is power out to thermostat and controller Y is demand for cooling input to furnace W is demand for heat input to furnace G is run fan with no demand or heat or cooling input to furnace C is return for power and is required for humidity controller to provide power return path. It is also used on high end thermostats that require power. Normal thermostat wire is 4 conductor for newer thermostats you may need the C connection. Home Depot has 5 conductor wire.

Possible, it would depend on how much access you (room) have below the floor line of the current installation,or you could install it on the return duct work which would be be at the top of the heater. if you do it this way and have central AC be sure to shut all water connections to the humidifier before you use the AC, or you will cause ice to build up on the AC coil, not a good thing. I suggest you contact a professional for final installation, as I can not and have not seen how your heater is installed, good luck:

It would first depend on the square footage of your home. Either way I would not suggest this one. I would go back to a console and haul a bucket of water versus taking one or two containers provided to fill the humidifier up every morning. When you decide on one (larger version) you will notice a big change of moist air in your home.

I don't understand your question. The orientation of the air handler shouldn't matter. The Aprilaire unit must be mounted vertically though as waterflow is driven by gravity. Control unit must be also vertically mounted to avoid dust and condensation accumulation.

Yes, AND to pull fresh air return. The rear of the cooling unit has 2 airflows, exhaust and return. The duct fan will assist with both airflows.

I'm not sure. In my case I already had an Aprilaire unit so I just replaced the humidification unit and re-hooked up the controls. I wouldn't worry about the warranty. You'd spend more getting them to handle claim than just buying another.

I doubt you can use this humidifier on your furnace. You need to get access to both the heat side and the return air side of the furnace. With a down draft furnace your heat ducts are all under the floor, so you do not have access to the heat side. I suggest you get a stand alone humidifier that does not connect to the furnace. I also suggest you find one that has a water line connection, because the ones with tanks you will have to fill at least once a day if not more often

I had the same problem. My Model 600 is not reversible. I solved it with a 6' flexible pipe used to make a U-turn to the point where it enters the warm air duct. Suggest you phone Aprilaire.

I do not have non ducted install. I do not know what your situation is regarding the application but if you cant duct it, the result wil be limited; not just for this brand but all brands.

If the goal is to install a humidistat controlled fan and it meets the desired CFM rating, it is nice packaging design to adapt to most any requirement. However,mine suffered early life failure after 6 or 8 months so I suspect the fans are not rated for 24x7 operation.

I'm not sure what the difference is between an 'A' and 'B'. Most likely, these are all universal as they just complete a connection between two low-voltage wires. If you only have two wires in your current humidistat, I'm sure this should work.
