tive barrier against cold drafts in the winter and hot humid air in
the summer. To achieve optimum protection, the unit should
be mounted on the inside of the building, flush to the wall (do
not obstruct the nozzle or air stream) and as close to the top
of the door opening as possible. See Figure 2.
