This hood was created to allow the CellarPro 1800 Series cooling units to be installed above - as opposed to inside - the wine cellar.
This hood is designed to fit over the front of the cooling unit, and acts as a plenum to capture return air from the wine cellar. Two mounting brackets on either side keep the cooling unit from moving around after installation.
When using this hood, the cellar must be located directly below the wine cooling unit - THIS UNIT SHOULD NOT BE DUCTED. Two openings must be created in the ceiling of the wine cellar, one for one for return air (using this hood) and one for supply air (below the exhaust fan).
