Features and Specifications ï WM-2500~12000SSDWC split water-cooled ceiling-mounted cooling systems are designed to provide a cold environment between 50~65 °F with a humidity range within 50~70% RH for a properly insulated wine cellar. ï These temperature and humidity ranges are optimized for long term storage of wine like that in natural caves. - Page 6 CAUTION The condensing unit must operate above 32°F ambient temperature. NOTE The cooling capacity is determined under 55°F cellar temperature, 75°F cellar ambient temperature and 90°F condensing unit ambient temperature, with R13 interior and R19 exterior insulations. Higher ambient temperatures or lower insulations will cause reducing capacity and the cellar temperature may not be maintained at 55°F.

WINE~MATE split system is shipped as components and is ready for use only after a certified refrigeration technician has properly installed the system. Proper installation is critical. Vinotemp can only warrant the quality of the components. The installation and proper operation of the system must be warranted by the installer. - Page 18 Parts not included: Liquid line copper tubing Suction line copper tubing Water lines Liquid and suction line locations may differ from that they are shown CAUTION below, please check on the units for proper installations. To prepare rough-in, leave minimum 4” clearances for electrical NOTE wiring and refrigeration piping.

Temperature Controller and Air Probe Location 1) The temperature controller can be mounted either inside or outside the wine cellar, but the air probe must be located inside. 2) The air probe shall be located in the wine cellar 5 ft above the floor or the air return area, but it shall not be located in the air supply area or other areas where air is not circulated.
- Page 22 may be recessed in the ceiling with short curved rectangular ducts in air supply, but the air flow CFM must be checked. 2) For a direct blow application, air supply shall be unobstructed minimum 12”. For a deflector application, leave 2” clearance for air supply. Air return shall be unobstructed minimum 6”.
