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 WINE~MATE split ceiling-mounted cooling systems WM-2500~12000SSD and WM-2500~12000SSD-LA 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. 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 NOTE R19 exterior insulations. Higher ambient temperatures or lower insulations will cause reducing capacity and the cellar temperature may not be maintained at 55°F.
Temperature and Humidity 1. The controller Fig. 2 TEMPERATURE CONTROLLER 1) Keys SET: To display set-point; in programming mode it selects a parameter or confirms an operation. : To start a manual defrost. : To see the maximum stored temperature; in programming mode it browses the parameter codes or increases the displayed value.

5. Manual Defrost Press and hold the defrost key until defrost starts. The defrost indicator will be 6. Parameter Programming 1) Press and hold the SET + keys until the “°C” or “°F” LED starts flashing, then release the keys. 2) Press and hold again the SET + keys until the Pr2 label is displayed, then release the keys.

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 Coil Cleaning Clean the condenser coil regularly. Coil may need to be cleaned at least every 6 months. Use a vacuum cleaner with an extended attachment to clean the coil when it is dusty or dirty.

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.
