Installing the Ductwork
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 7.5 metres for each length of ductwork run

Notes: 1. The above references izes are internal diameter in mm.
2. If a single supply is used out of the unit but then splits into two (2) ducts, the above size
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.
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
