Installing The Ductwork And Grilles; Recommended Insulated Flexible Ductwork Sizing Chart - Wine Guardian Sentinel Series Installation, Operation And Maintenance Manual

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 combined supply and return duct work
