Page 5: Features & Specifications
Features and Specifications • Wine-Mate rack split cooling systems WM-2500~6500SSVWC 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. - Page 6 NOTE: To prepare rough-in, leave minimum 4” clearances for electrical wiring and refrigeration piping. The specifications and dimensions are listed as follows: Electrical Weight (lb) Cond Unit Btu/h Cellar Size Model No Evap Unit Refrigerant Evap Unit/ Evap Unit/ L”xD”xH” (cu ft) Cond Unit Cond Unit...

Temperature and Humidity 1. Use of the controller Fig. 2 Temperature Controller 1) Keys SET: To display target set point; in programming mode it selects a parameter or confirm an operation. (DEF): To start a manual defrost. (UP): To see the maximum stored temperature; in programming mode it browses the parameter codes or increases the displayed value. - Page 8 4) Alarm Signals The alarm codes are described as follows. MESSAGE CAUSE FUNCTION Temperature probe faulty Compressor switching to Con and CoF Probe temperature ALU higher than the High temperature alarm setting temperature; Outputs unchanged Probe temperature ALL lower than the Low temperature alarm setting temperature;...
- Page 9 5. How to calibrate the air temperature probe If the actual cellar temperature differs from the displaying temperature, set ot = actual cellar temperature minus displaying temperature. 6. How to adjust defrost cycle In case there is excessive frost, the parameters FnC = C-y, idF = 6 and MdF = 20 can be used to avoid defrost.
- Page 10 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. 7) To exit: Press SET + or wait 15sec without pressing a key.

The fan will run from the minimum speed to full speed with the control knob at the lowest and highest speed position. To adjust the minimum speed, turn control knob to the lowest speed position, then rotate the setting (located on the side or front) clockwise to decrease the minimum speed or counter- clockwise to increase the minimum speed.
- Page 23 8) 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.
