Features and Specifications • WM-2500~6500SSVWC split water-cooled rack-recessed 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 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.

Care Guide In general, always unplug system or disconnect power while doing care. 1. Condenser Water Line Cleaning • To clear any sediment that may accumulate, the water regulating valve may be manually flushed. • Insert screwdrivers under both sides of the valve spring guide and lift upwards to flush. -

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 16 Parts not included: Liquid line copper tubing Suction line copper tubing Water lines Insulated Ducts CAUTION Liquid and suction line locations may differ from that what is shown 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 the wine cellar or the return duct. 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 19 1) The WM-25~65SFCV evaporator units should be installed for corner mount with the supply air on the top and return air on the bottom. 2) Air supply shall be unobstructed minimum 12”; air return shall be unobstructed minimum 6”. 3) A grille can be used to cover the supply and return with 0~2” clearance; or a 2- 3 ft long duct can be added at the supply and return.
- Page 20 2) If the line set exceeds 75 ft long, use both inverted U trap and suction accumulator to prevent liquid from flooding back to the compressor. 3) If the condensing unit is located below the evaporator unit, use inverted U trap to prevent liquid from flooding back to the compressor.
