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-2500~6500SSRWC split water-cooled rack-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. • These temperature and humidity ranges are optimized for long term storage of wine like that in natural caves.

If the condensing must operate above 32°F ambient CAUTION 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.

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.
