Page 16: 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. - Page 17 CAUTION: Liquid and suction line locations may differ from what are shown here, please check on the units for proper installation.

- Page 23 • 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 24 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.
- Page 25 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.
