  • Page 7: Receiving, Inspecting And Unpacking The Wine Guardian Unit

    Guardian fan coil and condensing unit. These ship from separate manufacturing facilities and therefore may not arrive on the same date and time. Each Wine Guardian component is shipped in a corrugated box. A shipment may include one or more boxes containing accessories.

  • Page 8: General Description

    Wine Guardian uses digital electronic controls and R-134a refrigerant. The entire Wine Guardian fan coil section is tested at the factory and the condensing unit is shipped separately. All components are of a high quality standard commercial grade. The entire system is approved by ETL according to UL 1995 and CSA safety standards.

  • Page 9: Wine Guardian Fan Coil Unit

    The Wine Guardian fan coil section operates as air passes through the cooling coil and is cooled by the refrigerant inside the coil. This causes any excess humidity in the air to condense and be captured in the drain pan and piped outside the unit.

  • Page 10: Accessories And Optional Equipment

    Duct Collars and Flexible Ducts Ducting for the Wine Guardian is sold in kits by size for each unit. Each kit contains two adapter collars, one 8m length of round flexible duct and two straps. The number of duct kits needed depends on the wine cellar layout and application.
