Vintage Cellars Wine Guardian Water-Cooled Cooling System - Manual (Page 33)

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 90° 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 9 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).
