Features and Specifications • WM-2500~8500SSLWC split water-cooled low-profile 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. • These temperature and humidity ranges are optimized for long term storage of wine like that in natural caves. - Page 6 If the condensing unit will operate below 50°F, install a low CAUTION ambient condition kit. 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.

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 17 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.
