where should the bypass ductwork be installed for this model? The return vent or above the furnace? I have seen it in the return in some pictures.

I installed mine on the supply above the furnace. The Aprilaire is on the return.

The humidifier can be installed on either the supply or the return plenum, so its where you have the room to put it.

I installed mine in the middle of a duct run. I attached duct adapters to each side of the blower then I installed it to the ducts. I found it impossible to attach it directly to the ducts. I also purchased an extension cord device that had a remote control feature. One thing I will tell you is that with this installed, unless it is running, little air flow will make it through the booster fan. Otherwise it's amazing. I only wish I could connect it somehow so it would turn on and off with the central air on/off. Good luck. The only mistake I made was not buying the bigger unit. I wish I had bought the 10" and used adapters to step down to the duct size. I installed mine in the middle of a duct run.

Sorry I missed that it was not installed. You may not need one unless you have a humidifier or electrostatic filter. In which case there should be wires coming from either side at the lower half of the furnace trace those to perhaps a shut off switch. Thoses wires will tie into the transformer and a power source. If you cannot find the wires coming out you need to have the contractor finish the job.

On the 500 model, the air can flow either direction. The enclosed instructions tell you how to mount it on either the supply or return ducts.

I installed an intake fan since my power supply has a 120mm fan that is providing the exhaust functionality. That setup seems to keep everything pretty cool (&lt;40 C).

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.

I have installed this on a down flow furnace and it works fine. There are many other considerations as to whether this will work for your application. Space on the hot and cold air duct work, water source, electrical supply, etc. If you are unsure, find a professional for the installation.

There is not an explanation of vent space required on the back. I suggest to call the factory and inquire.

I would read all the reviews to decide whether or not to do-it-yourself. The scope of the installation will vary depending on how your furnace is equipped. At a minimum, you will have to cut accurate holes in ductwork, read electrical scematics/diagrams, do electrical and plumbing work. Ideally, you will need to be in close proximity to water supply, drain and electrical outlet. If you are unsure, you should probably hire it out.

You have to have the exhaust hose vented out a window. Otherwise you are defeating the purpose of cool air and the hot exhaust.

Ductwork would have to be installed to direct heat forward and also for air intake from the side. Hangar system would also have to be installed behind wall studs. In my view, not worth that effort and expense plus it would probably void the warranty.

Your kit should have come with the bypass valve. This is mounted under any sink between the hot and cold water pipes. Best location is at the farthest point from the hot water tank. I actually have 3 of these bypass valves installed because of the way the hot water is distributed throughout the house. You should have a flex pipe between the cutoff valve and the faucet for both the hot and cold. These flex pipes feed the bypass valve and you will then need two more flex pipes to go from the valve to the faucets. If your kit did not come with the bypass valve and pipes, you can order them online. The valve is referred to as a comfort valve, also from Grundfos. This system works great. I have the timer set to come on about an hour before I get up and run for 3 hours in the morning and 3 hours in the evening.

We had to vent or separately and it seemed as of code required it. At least that is what the plumber suggested. A plumber needs to install it so the warranty does not get voided.

They are wired to the main control unit which can be mounted right on the furnace. That is where I mounted mine and it would have been a short distance to run wires, but I decided to not use the duct sensors.

There is a drain in the back of the unit at floor level. I added a condensate pump to boost it from the floor out a window. There is also a very large exhaust hose that goes with an included window mount.

That is a vent. And mine came with two different options, mine is lower.. I will see if I can get a picture to attach.

I put under stove exhaust fan while using. Assuming you have vented range hood.
