## Questions & Answers

**Q: Is it better to mount it low or high when establishing a transfer with the basement stairs?**
A: I would imagine if it's for basement stairs, it wouldn't really matter. I'm not a professional though.

**Q: I received the product and the baffle is made out of cardboard. How am I supposed to clean cardboard? This could also lead to mold/ mildew issues.**
A: Compressed air would be suffencent to blow through and remove any contaminates.  Card board is on sheet rock in the walls already and with all the airflow I seriously doubt mold would ever be an issue. Typically mold requires moisture and restricted or no air flow to thrive

**Q: Is this a Through Wall install to be used between rooms?**
A: Unless one room only has a supply vent and the other room only has a return vent, there wouldn't really be a benefit of installing this item in a wall between said rooms.  The only exception would be if a whole closed-door room is an obstacle out to the open area.  Then you'd need two of these to install on opposite walls to create a full pass-through.  At any rate, most cookie cutter houses have supply vents in every room, and only one large return out in a hallway or common area.  So, this product is more so intended to be installed through the wall between a positive pressure area (such as a bedroom with only a supply vent and door) and a negative pressure area (such as the hallway or open area where the return is).

**Q: Where are the installation instructions in the box? I can't find what size openings to cut, how to align both cuts, where to locate the vent, etc.**
A: To my recollection, instructions were not included. I chose an approximate desired location in my wall, located studs with a stud finder, and outlined the hole using one of the flanges and a level. Once cut though on one side, I marked the inside of the wall for the second cut. If you do not feel comfortable with the project, contact a handyman … shouldn’t take more than an hour per vent.
