Yes, you can install them next to each other but there are some things you will want to keep in mind. Anything that comes out past the case will be an obstruction. If there is a wall or cabinet preventing the door from opening all the way, the side with the obstruction will require 12" clearance. Crispers can be opened all the way at 90 degrees. To remove crispers, doors must be fully opened (130 degrees). Per the quick specs, about 2 inches is needed to open the door at 90 degrees, so we would suggest at least this much space between units, so at least one can open at a time without hitting the other. If you want to open doors to both at the same time, and want to open them fully, they will need 24 inches between.
