Locating the Unit
Wine Guardian units are typically installed indoors located near the cellar to minimize the duct
runs. Each unit is provided with one entering or return air inlet and three possible supply air
outlets for each of the evaporator and condenser sections. A maximum cumulative total length
for both supply and return ducts (including bends) of 25 feet is recommended. If longer runs are
needed use more than one supply opening to reduce the airflow in each duct by ½. See Recom-
mended Flexible Ductwork Sizing Chart on page 30.
Provide a 3 foot clearance around the unit for removal of grilles or ductwork, access to filters and
unit maintenance. If the humidifier is used, provide access space in front of it for service.
Grilles
Each of the inlets and one evaporator outlet and one condenser outlet come from the factory
with grilles over the openings. The grilles are removable. Remove the necessary grilles for installing
ductwork between the unit and the cellar. If desired, use the grilles as wall grilles inside the cellar.
The return air, or inlet, to the unit must connect to the return air outlet from the cellar. Any of the
three supply air outlets on the unit can be used for the ductwork to the supply grille inside the cellar.
The factory installed outlet grille can be relocated to any of the other two openings. The procedures
below apply to both the evaporator and the condenser sections. In most cases, no ducts are in-
stalled on the condenser section because the unit is located in a mechanical or storage type space. If
exhaust heat is undesirable use the grilles to install ductwork to move the heat outdoors or to another
space. Also, use ductwork to direct condenser air noise away from occupants.
Reducing Noise From the Unit
Consider noise when locating the unit close to the cellar or an adjacent occupied space. A
piece of 1" or 2" dense rubber or styrofoam with foil face in between the unit and the wall
absorbs and reduces the noise from the unit. For air noise use better grilles or block the noise with
a solid piece of wood or styrofoam. Sound usually travels as a line of sight. Sound is reduced when
it turns a corner, such as, passing through a bend in ductwork. If the unit is
supported from a wall or joist, using a rubber pad under the unit will reduce vibration transmis-
sion.
