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 duct packaged cooling systems WM-4500~8500DS 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. It is self-contained ready for use and no extra refrigeration tubing is required in the field.
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 Dimension L”xW”xH” WM-4500DS 45x34x23 WM-6500DS 45x34x23 WM-8500DS 45x34x25 Btu/h CFM 4500 380 6500 490 8500 750 Cellar Size (cu ft) Refrigerant Electrical Rating Weight (lb) 1000 R134a 115V-60HZ-8A 140 1500 R134a 115V-60HZ-14A 170 2000 R134a 115V-60HZ-17A 220 Fig.
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 packaged duct system is shipped 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 of the system must be warranted by the installer.
Fig. 5 Temperature Controller (4.25”L X 3.75D X 4.25”H) Parts included: Packaged Cooling system Temperature Controller (4.5”LX4.5”WX3.75”D) + Air Probe Parts not included: Insulated ducts CAUTION: Low ambient condition kit is required if the installation area will be below 50°F. 2. Location • Place the unit in a properly ventilated location. If it is not, heat exhausted by the condensing unit will build up and the cooling system will not operate properly.
3. Mounting • The unit must be mounted on a floor or slab that is level and strong enough to support up to 300lb. • There are six ½” bolts required to secure the unit base. • There is a gravity drain system used, so the unit shall be installed level or with a slight slope downward the drain connection and the drain line shall be installed slope down toward the drain. 4.
• If the low ambient condition kit is used, turn off the compressor and power the condensing unit (The compressor switch is located at the outlet box of the condensing unit). Then turn on the compressor and power the evaporator unit after the condensing unit has been powered for 12 hours. NOTE: • Make sure the fan speed control is turned on. • • • Turn on the power. Press temperature controller to turn on the unit. It is necessary to check the air flow to meet the specified CFM.

Fig. 10 Condenser Fan Cycle Control B. Use of the crankcase heater The crankcase heater is installed around the lower part of the compressor and shall be turned on all the time. The heater is self-regulated. 3. Refrigeration Piping and Leak Testing NOTES: • 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.
2. Connecting Electrical Wires Connect all electrical components using the wiring diagrams in accordance with all state and local codes. 4. Evacuating, Charging and Starting the system CAUTION: • Always use the superheat and subcooling, pressure readings to charge refrigerant properly; the listed charge amounts are used for reference only. • If the unit is equipped with a low ambient condition kit and installed in the summer, charge 15% more refrigerant.
7) If the superheat is high, check the subcooling first to know if the refrigerant charge is sufficient. If the charge is not sufficient, add more refrigerant. If the charge is good, then increase the evaporator suction pressure by turning the hex nut (5/16”) clockwise. Liquid must always be charged into the hide side when the compressor runs. 8) If the superheat is low, then decrease the evaporator suction pressure by turning the hex nut (5/16”) counter-clockwise.
4) High to normal suction pressure and high head pressure Low subcooling 5) High suction pressure and high head pressure Low superheat and low subcooling 6) High suction pressure and high head pressure High superheat 7) Low suction pressure and low head pressure High superheat and low subcooling 8) Low suction pressure and low to normal head pressure High superheat and high subcooling 9) Low suction pressure and low head pressure Normal to high superheat and low subcooling 10) Low suction pressure and low h
Electrical Wiring Diagrams CAUTION: • Hidden lines are the field wirings • Use minimum 14 gauge wires for power lines. • If equipped with low ambient condition kit, use low ambient temperature wiring diagrams. • A safety switch is always recommended for the condensing unit. Fig.
