Parameter Programming keys until the “°C” or “°F” LED starts flashing, then 1) Press and hold the SET + release the keys. 2) Press and hold again the SET + keys until the Pr2 label is displayed, then release the keys.
Page 10 8. How to adjust defrost cycle 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.
Page 11: Care Guide
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.

Page 15: Installer's 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.

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.
Page 19 4. Condensing Unit Installation CAUTION: Low ambient condition kit is required if the installation area will be below ° 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.

Page 22 • 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.
Page 23 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.
Page 24 To read properly the service valves must be in the middle positions. Complaint Possible Causes 1) High suction pressure and low head pressure 1) Compressor may be bad Zero superheat and zero subcooling 2) High suction pressure and low head pressure 2) Expansion valve opened, too Low superheat and low subcooling much oil...
Page 25 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.
