Cellar Construction This is only a guide and shall be considered as minimum requirements. All interior walls 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. The vapor barrier shall be installed on the warm side of the insulation.
Features and Specifications • • • • • • • Wine-Mate ceiling mount split cooling systems WM-2500~6500SSLWC are designed and used to provide a cold temperature between 50~65 °F for a properly insulated wine cellar. The wine cellar will maintain humidity range within 50~70% RH. These temperature and humidity ranges like in natural caves are optimized for long term storage of wine.
The specifications and dimensions are listed as follows: Model No WM2500SSLWC WM4500SSLWC WM6500SSLWC Evap Unit W”xD”xH”A”xB” WM-25SFCL 31.75x14.5x4.7529.75x14.75 WM-45SFCL 40.25x14.5x4.7538.25x14.75 WM-65SFCL 53.75x16.5x6.7551.75x16.75 Cond Unit L”xD”xH” WM-250SCUWC 24x18x18 WM-450SCUWC 24x18x18 WM-650SCUWC 24x18x18 Btu/h CFM Cellar Size (cu ft) Refrigerant Electrical Evap Unit/ Cond Unit Weight (lb) Evap Unit/ Cond Unit 2500 275 250 R134a 115V-60HZ-0.4A 115V-60HZ-5.
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. : To see the minimum stored temperature; in programming mode it browses the parameter codes or decreases the displayed value. : To turn on/off the power to the unit.
4) Alarm Signals The alarm codes are described as follows.
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. The first parameter Hy will be displayed. 3) Press up/down keys / to scroll to the required parameter within 10 sec. 4) Press the “SET” key to display its value. 5) Use up/down keys to change its value within 10 sec. 6) Press “SET” to store the new value and the display will flash 3 times.
In case there is excessive frost, the parameters FnC = C-y, idF = 4 and MdF = 20 can be used to avoid frost. 9. How to adjust the humidity The parameter Fon is used to adjust the humidity in the wine cellar. Higher Fon results in higher relative humidity. Use a separate hygrometer to monitor the humidity. 10. How to set alarm call 1) Speech notice will be sent to your phones when the cellar temperature is ALU higher or ALL lower than the set-point Set.
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. 2. Condensate Removing • Remove the excessive condensate if it is accumulated in the wine cellar at high humidity conditions.

Installer’s Instructions Federal law requires that WINE-MATE split cooling systems be installed by an EPA certified refrigeration technician. 1. General Instructions 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.
CAUTION: Liquid and suction line locations may differ from what are shown here, please check on the units for proper installation. Fig. 3 WM-25SFCL Evaporator Unit Fig.

Fig. 8 Temperature Controller (4.25”L X 3.75D X 4.25”H) 2. Temperature Controller and Air Probe Installation 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. 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.
amount of water must be provided for constant head pressure and proper cooling, but excessive water flow will cause the unit working inefficiently. 3) The maximum permissible water pressure is 150 PSIG. If water pressure is excessive, a pressure reducing valve must be used to reduce the water pressure.
Suction pressure setting: Cut out=10 psig; Cut in=25 psig; Differential=15 psig Head pressure setting: Cut out=230 psig; Cut in=150 psig; Differential=80 psig It may need to adjust the setting in the field to get the right cycle time. Fig. 11 Adjustable Pressure Control 6.

Water Piping If a water pump is used, install it before the water inlet so that the condenser cooling water is fed from the discharge side of the pump.
Fig. 12 Water Regulating Valve 2) The subcooling at the condensing unit shall be around 10°F. The charge may be complete when there are no more bubbles forming in the liquid indicator. 3) Head pressure is maintained constant but will vary with the water outlet temperature: 120 ~ 190 psig at the water outlet temperature 95 ~ 120 °F. 4) The evaporator’s constant pressure expansion valve is set around 30 ~ 35 psig (35 ~ 40°F) at factory.
