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 rack split cooling systems WM-2500~6500SSR 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. SSR units consist of a condensing unit and an evaporator unit; they are connected by a liquid line and an insulated suction line.
NOTE: To prepare rough-in, leave minimum 4” clearances for electrical wiring and refrigeration piping. The specifications and dimensions are listed as follows: Model No WM2500SSR WM4500SSR WM6500SSR Evap Unit L”xD”xH” WM-25SFCR 32x11.125 x11.375 WM-45SFCR 38x11.125 x14.375 WM-65SFCR 38x11.125 x14.375 Cond Unit L”xD”xH” Btu/h CFM Cellar Size (cu ft) Refrigerant Electrical Evap Unit/ Cond Unit Weight (lb) Evap Unit/ Cond Unit WM-250SCU 18x14x12 2500 220 250 R134a 115V-60HZ-0.77A 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. 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. 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.

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.
installed slope down toward the drain. If rise-up is needed, a condensation pump must be used. 4. Condensing Unit Installation CAUTION: Low ambient condition kit is required if the installation area will be below 50°F. If the condensing unit is equipped with a low ambient condition kit, do not turn on the compressor until the condensing unit has been powered for minimum 12 hours. 1) Place the condensing units WM-250~650SCU in a properly ventilated location.
BACK POSITION FRONT POSITION MIDDLE POSITION Fig. 10Base Valve Operation 5. Checking Pressure Control Settings 1) Use of the adjustable pressure control (if applicable for pump-down) Suction pressure setting: Cut out=5 psig; Cut in=25 psig; Differential=20 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. A. P70 Single/Dual Control B. PS2 Dual Control Fig.
2) Use of the encapsulated pressure control (if applicable) Fixed suction pressure setting: Cut in = 32 psig; Cut out = 10 psig Fig. 12 Fixed Pressure Control 3) Low ambient condition kit (if applicable) A. Use of the condenser fan control Head pressure setting: Cut in=170 psig; Cut out=110 psig; Differential=60 psig It closes on rise of pressure. It may need to adjust the setting in the field to avoid fan short cycle. Fig. 13 Condenser Fan Cycle Control B.
• • • The line connection sizes of liquid filter & indicator, the valve connection sizes of condensing unit and the line connection sizes of evaporator unit are not necessary the same as the listed refrigeration line sizes. If the condensing unit is installed above the evaporator unit, use the suction line one listed size smaller. Expansion and solenoid valves have been installed on the liquid line in the evaporator.
1) Evacuate the system; both discharge and suction valves must be in the middle positions during evacuating. 2) Charge the system through both suction and discharge valves with refrigerant using the recommended initial amount; both discharge and suction valves must be in the middle positions during charging. 3) Turn on the power to start the system and check the following temperatures and pressures. 9.
8) If the superheat is low, then decrease the evaporator suction pressure by turning the hex nut (5/16”) counter-clockwise. 9) Both discharge and suction valves must be in the back positions before disconnecting. 10) Close all service valves and disconnect all manifolds and hoses. Fig. 15 Expansion Valve 10. Pressure, Superheat and Subcooling Readings CAUTION: To read properly the service valves must be in the middle positions.
