General Duct Recommendations
✓
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 13 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
.
NOTE: 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

Reducing Noise from the Unit
Consider noise when locating the unit close to the cellar or an adjacent occupied space. A piece of
one – or two-inch dense rubber or Styrofoam with foil face in between the unit and the wall
absorbs and reduces the noise from the unit. In case of air noise use larger 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, place a rubber pad under the unit to reduce vibration transmission
