Installing the Ductwork and Grilles
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.
Use ductwork on the condenser section to redirect or absorb sound, to bring in outside air to the unit
inlet, and/or to exhaust the hot air out of the ambient space.
NOTE: Do not exceed a total of 25 feet for each length of ductwork run
.

Notes: 1. The above referenced sizes are internal diameter in inches.
2. If a single supply is used out of the unit but then splits into two ducts, the size above
that is recommended for double is used after the split
.
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 the 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.
�
Locate the supply or return air grille where it is blocked by bottles, boxes or cases.
�
Locate the supply air grille where it blows directly on the thermostat.
Relocating a grille on the Wine Guardian
1)
Remove the fasteners from the grille.
2)
Remove the fasteners from the access door panel to be replaced by the grille.
3)
Relocate the outlet grille to its new location and secure in place using its fasteners.
4)
Replace the access door panel where grille was located.
