Important Safety Information WARNING To avoid the risk of electrical shock, property damage, personal injury, or death: • The power cord must be plugged into a 3-prong grounding type wall receptacle, grounded in accordance with the National Electrical Code, ANSI/NFPA 70 – latest edition and local codes and ordinances. •...
Cellar Construction Guide This is only a guide and shall be considered as the minimum requirements. All interior walls, ceilings and floors shall have a vapor barrier and a minimum of R13 insulation. All exterior walls and ceiling shall have a vapor barrier and a minimum of R19 insulation.
Features and Specifications • WM-2500~4500SSWWC split water-cooled wall-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.

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. Higher ambient temperatures or lower insulations will cause reducing capacity and the cellar temperature may not be maintained at 55°F.

7. How to calibrate the air probe If the actual cellar temperature differs from the setting temperature, set parameter ot = actual cellar temperature minus set-point. 8. How to adjust defrost settings In case there is excessive frost, the parameters FnC = C-y, idF = 4 and MdF = 20 can be used to avoid frost.
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.

Temperature Controller and Air Probe Location 1) The air probe shall be located in the wine cellar 5 ft above the floor or the air return area. 3. Evaporator Unit Location 1) The WM15~45SFCW evaporator units shall be installed for wall mount with the air supply on the top side and air return on the bottom side.
Page 19
4. Condensing Unit Installation Condensing unit shall be elevated to avoid possible flooding and shaded from direct sun. The location shall not be subject to freezing temperatures. Water must be supplied to WM-250~450SCUR-WC at all times during operation, with the maximum outlet temperature of 120 °F. A sufficient amount of water must be provided for constant head pressure and proper cooling, but excessive water flow will cause the unit working inefficiently.
