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 wall split cooling systems WM-1500~2500SSW 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. SSW 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 Evap Unit L”xD”xH” Cond Unit L”xD”xH” Btu/h CFM WM1500SSW WM2500SSW WM-15SFCW 16x5.5x36 WM-25SFCW 16x5.5x36 WM-150SCU 18x14x12 WM-250SCU 18x14x12 1500 105 2500 175 Cellar Size (cu ft) Refrigerant 150 R134a 250 R134a Also see Fig. 3 & 4 for further info. -5- Electrical Evap Unit/ Cond Unit 115V-60HZ-0.35A 115V-60HZ-3.
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.
Fig. 4 WM-150~250SCU Condensing Unit Fig. 5 Liquid Filter Fig.6 Liquid Indicator 2. Temperature Controller and Air Probe Installation 1) 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. 2) Air probe can be pulled out of the temperature controller around 5 ft; if additional wires are needed, 18 gauge wires may be used to extend the air probe. 3.
2) Air supply shall be unobstructed minimum 12” for a direct blow installation; leave 2” clearance for a deflector installation; air return shall be unobstructed minimum 6”. 3) A grille can be used to cover the supply and return with 0~2” clearance; or 2-3 ft long duct can be added. 4) 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.

Checking Pressure Control Settings 1) Use of the encapsulated pressure control (if applicable) Fixed suction pressure setting: Cut in = 32 psig; Cut out = 10 psig Fig.
A. 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. B. 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. 10 Condenser Fan Cycle Control 6.
difference is more than 10 ft or the line set exceeds 75 ft, use both inverted U trap and suction accumulator. 3) If the condensing unit is located more than 10 ft above the evaporator unit, use U trap to aid oil returning to the compressor. 4) Complete pipe brazing, check solenoid valve and expansion valve restrictions and test leak. 5) Hook up the drain line and check if water drains. The line sizes and refrigerant charges are listed as follows.
clockwise to increase the minimum speed. The minimum speed should be adjusted until it supplies the required CFM. Fig. 11 Fan Speed Control 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 range: 120 ~ 150 psig at 70 ~ 90 °F condensing unit ambient temperature. 4) The evaporator’s constant pressure expansion valve is set around 30 ~ 35 psig (35 ~ 40°F) at factory.
10. Pressure, Superheat and Subcooling Readings CAUTION: To read properly the service valves must be in the middle positions.
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.
