Ductwork - Wine Guardian SP25 Installation, Operation And Maintenance Manual

Ductwork

Wine Guardian units are typically installed indoors near the wine cellar to minimize duct
runs. Each unit is provided with one entering (or return) air inlet and five possible supply
air outlets for each of the evaporator and condenser sections. A maximum cumulative
total length for both supply and return ducts (including bends) of 25 ft (7.5 meter) is
recommended. If longer runs are needed, examine your duct runs using our
Calculator.
Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use
only insulated ductwork to minimize cooling losses, to 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. 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"
ducts).
