Installing the Ductwork and Grilles
Duct Collars
One inlet duct collar and one evaporator outlet are supplied with each fan coil unit as standard
equipment from the factory. The duct collars are removable. The return air, or inlet duct collar
must connect to the return air outlet from the wine cellar. Any of the five supply air outlets on the
unit can be used for the ductwork to the supply grille(s) inside the wine cellar. The factory
installed supply duct collar can be relocated to any of the five openings as needed.
Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only
insulated ductwork to minimize cooling loses, prevent sweating, and to reduce noise.
NOTE: Do not exceed a total of 25 feet (7.62 meters) of ductwork run
(combined supply and return).

CAUTION
RISK OF DAMAGE TO EQUIPMENT
Avoid crimping the flexible ducts. This chokes down the inside area and reduces the airflow,
causing the unit to operate erratically.
Be sure all ducts and surface in contact with the airflow are insulated
and have a vapor barrier on the outside surface
.
NOTE: Uninsulated ducts and surfaces cause bare exposed metal surfaces to
sweat, further degradation of the insulation and a loss of equipment cooling
capacity.
Location of Supply and Return Grilles
Locate supply and return grilles inside the cellar to create an airflow pattern that maximizes air
circulation in the room. Avoid short circulating of the air.
✓
Do not install the return air grilles directly on the floor as the grilles will collect dust from
the floor.
✓
Do not locate the supply or return air grille where there are blocked by bottles, boxes or
cases.
✓
Do not locate the supply air grille where it blows directly on the remote interface
controller.
