Fantech vhr2005r verify installation
Hello,
My wife and I are wondering if the air exchanger is correctly setup in our house. The reason i ask is we had a lot of moisture on our windows over thanksgiving that never really went away.
When i opened it up it seems strange to me that both lines were hooked into the return venting as wouldn't this mean that they are sucking air? Should one be pulling from the return venting and then the other pipe pushing exhaust out so it seems to me one should be sending air into the unit the other sending it out? Here are some images for reference and help perhaps.
Description of what i mean by the text on the image if that helps.
pushes air to outside type vent. what i mean by that is there are fins that it closes when no air coming out.
draws air in from outside means that the vent is always open sort of thing.
is this setup correctly?

Thanks for the reply and image. that is helpful. So it seems that perhaps the one marked "stale air from inside" is incorrect and should be installed on the blower side of the furnace right so this would be similar to a vent in the home? However, if i do that though wont it constantly be blowing air outside then as there is no mechanism to stop it?

I was trying to read your diagram but the print is too small.
With the exchanger..... you are relying on its internal fans to move the air..... not the blower for the heating system.

oh sorry about that I was trying to give some info on the direction of the air. Since both are hooked in to the return they are both pulling air back. What are saying and so i understand the fan on the exchanger must then be able to draw enough of that stale internal air to counteract the suction of the return on the furnace. Is that the idea? If so then it seems it might be hooked up correctly then.
It might have been too that it was thanksgiving and there was just a lot of cooking and food and people and all of that to increase the moisture levels in our bathroom which is the furthest line from our furnace.
Please tell me if i should open another thread for this question but it is along the same lines I think here. I mention that it is the furthest from the furnace so is always colder back in that area. (north side of house too) I have access to the main trunk (I think that is what you call it from the furnace. ) where the vent lines feed off of to heat the bathrooom and bedroom back in this area. (unfortunately I dont have access to the lines that feed off of the trunk without tearing out sheet rock and such in the basement) Is there a way to increase the airflow perhaps to better equalize the heat as it is always a good 5-10 degrees colder back there in the winter time then any other location in the house?
Thanks again for the assistance here.

The left fan pulls air in from the house and blows it outside.
Your picture states that this fan is pushing air out of both ducts.
It is much more likely that you are mistaken than this fan could accomplish this.
I recommend checking the 4 ducts with a manometer.
