If your cellar includes: Large glass panels Stone or concrete surfaces High ambient exposure Poor door sealing You may require upsizing beyond cubic footage guidelines. When in doubt, confirm via cooling load evaluation. How the Ceiling Mount Split System Works This is a ductless split cooling system: The evaporator installs inside the cellar ceiling. The condenser installs remotely (garage, attic, utility room, or outdoors with housing). Refrigerant lines connect both units (up to 100 line feet). No ductwork required. Because the compressor sits outside the cellar, interior noise is reduced compared to through-the-wall systems. Performance Capabilities Maintains 55°F cellar temperature Designed to operate with condenser air intake temperatures up to 110°F Suitable for warm-climate installations (with proper ventilation) CFM: 321Refrigerant: R-134a Wine cooling systems are engineered for temperature stability, not rapid cooling like comfort HVAC. Installation Requirements Professional HVAC-R installation is required.Failure to use a licensed technician voids the warranty. Minimum cellar requirements: Full insulation Continuous vapor barrier Airtight door seal Dedicated 115V circuits Proper drainage planning Improper room preparation is the most common cause of system failure.
