Uninsulated ducts and surfaces cause bare exposed metal surfaces to sweat,
further degradation of the insulation and a loss of equipment cooling capacity.
General Duct Recommendation
 Support the flexible duct often to prevent sags or bends.
 Stretch the duct to make for a smoother interior for less air resistance.
 For a 90 degree bend, insert a metal elbow inside the flexible duct to avoid crimping.
 Do not squeeze or reduce the inside diameter of the ducts. This restricts the
airflow.
 Use short and straight ductwork.
 Review the configuration schematic on the Overview Sketch on page 8 for
information about which panels are available for duct connections and service.
 Remove the panels or grilles from the openings to connect the ductwork.
 Check that all the fan blades move freely.
 Check for loose foreign objects in any of the air paths.
 Connect the round flexible ducts to the Wine Guardian using the duct collars
provided with the duct accessory kit.
 Pull the outer plastic wrapping and insulation away from the end of the duct to
expose the reinforced inside duct liner.
 Use tie straps of clamp around the
inside liner to fasten the duct collar.
Do not clamp around the outside insulation. It compresses and loosens over time.
 Secure the duct collar to the unit using the screws provided. Be careful not to damage
or bend the gasket.
Not Using Ductwork

The supply and return grilles stay on the unit if no ductwork is used.
 The supply and exhaust grilles may be relocated to any of three openings. (Refer to the
manufacturers installation instructions located in the box of flexible ductwork).
Using Ductwork
Cold Air to/from Wine Cellar
 Remove supply air grille or access door panels to install ductwork between the Wine Guardian
unit and the cellar.
 Connect the supply air ductwork from the cellar to the supply air inlet at the Wine Guardian unit.
 Connect the return air ductwork from the cellar to the return air inlet at the Wine Guardian unit.
Warm Air to/from Condenser
 Connect ductwork on the condenser to direct heat and the air noise away from occupants.
 Connect ductwork to another space within the basement, a building or to the outdoors if the heat
being exhausted is undesirable.
