Mounting the unit in the cellar has a significant impact on the unit's ability to cool the air in the room. A law of nature states that warm air rises while cool air falls. The unit must be mounted high in the room in order to capture the warm air and cool it. If the unit is mounted low in the cellar, it has a tendency to circulate the cool air at the bottom of the cellar but has no ability to draw the warm air from the higher space in the Cellar. This will result in an inconsistent temperature range within the cellar itself.
