Page 5: Features & Specifications
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. - 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: Dimension Btu/h Cellar Size Model No Refrigerant Electrical Rating Weight (lb) L”xW”xH” (cu ft) 4500 WM-4500DS 45x34x23 1000 R134a 115V-60HZ-8A 6500...

Temperature and Humidity 1. Use of the controller Fig. 3 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.

Page 15: Installer's 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. Installation of the system must be done in accordance with all state and local building and electrical codes. - Page 16 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.
- Page 17 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.
- Page 18 • It is necessary to check the air flow to meet the specified CFM. It may use fan speed control to adjust the system refrigeration performance to achieve 8- 10°F differential between return air and supply air while wine room temperature is maintained 55°F.

- Page 21 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. Piping, Checking and 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.
- Page 22 • If the low ambient condition kit is used, turn off the compressor before power the condensing unit. Only turn on the compressor after the condensing unit has been powered for 12 hours. 1) Evacuate the system; both discharge and suction valves must be in the middle positions during evacuating.
