Wine Guardian D088 Installation, Operation And Maintenance Manual page 25

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.

It is best to oversize ductwork if exact ductwork diameters are not readily available or easily accessible
Note: The above-referenced sizes are internal diameter in inches for 60Hz and in
millimeters for 50Hz. If a single supply duct is used but then splits into two ducts, the
duct size that is recommended for double duct runs is used after the split occurs (ex.
8" duct would split into two 6"
