Important Safety Information
•DO NOT USE A GROUND FAULT INTERRUPTER (GFI).
•A DEDICATED 20 AMP CIRCUIT IS HIGHLY RECOMMENDED.

Feature Description
•Wine-Mate split cooling system is designed and used to provide a cold
temperature between 50~65 °F for a properly insulated wine room at a
normal environment.
•The wine room will maintain humidity of 50~70% RH even when the
environment becomes dry and humid.
•These temperatures and humilities are optimized for long term storage of
wine.
•The condensing unit can be located away from the wine cellar or other
refrigerated enclosure as far as 50 feet, which will bring you quiet
operation.
•The SSD units provide two way air supply operation. The evaporator units
can be installed on the ceiling in a cabinet or room.
The dimensions and capacities are specified as follows:

Installer’s Instruction
Federal law requires that WINE-MATE split cooling systems be
installed by an EPA certified refrigeration technician.
WINE-MATE split system is shipped as components and is ready for use only
after a certified refrigeration technician has properly installed and tested 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. Installation of the system must be done in accordance
with all state and local building codes.
The condensing unit and evaporator unit are connected by a liquid line and an
insulated suction line that are supplied by the installer. These lines must be
properly sized for the distance between the two units. After the units and the lines
are installed, the system must be pressure tested. If no leaks are found,
evacuate and charge system with R134A. Refrigerant amount will vary
depending on the length of line set.
1. Condensing Unit
•Place the condensing unit in a properly ventilated location. If it is not, heat
exhausted by the condensing unit will build up and the cooling system will
not operate properly.
•Leave minimum 5 feet clearance for the exhaust side and leave minimum
1 foot clearance for the fresh air intake side.
•Condensing unit should be elevated to avoid possible flooding and shaded
from direct sun. It should not be exposed to temperatures higher than 110
°F or lower than 45 °F (optional low ambient kit for 20 °F).
2. Evaporator Unit
•The WM25-85SFCD evaporator units should be installed for ceiling mount
with air supply on both sides and air return on the bottom.

- 7 -
•Supply and return air flow from the evaporator unit should be unobstructed
for at least 1 foot.
3. Air Sensor
•The air sensor can be located in the wine room or the return air area, but
not the supply air area.
4. Refrigeration Piping and Charging
•If equipped with a TXV, the evaporator superheat is set around 8 °F for a
10 °F TD system at factory.
•If equipped with an AXV, the valve is set around 38-40°F at factory.
•The charge may be complete when there are no more bubbles forming in
the sight glass. The subcooling at the condensing unit is around 10°F and
the superheat at the evaporator unit is around 8°F at 75°F ambient
temperature.
•The installation order starts from condensing unit (including the receiver),
liquid line filter-drier, moisture-liquid indicator (sight glass), liquid line,
evaporator unit (including liquid line solenoid valve and thermostatic
expansion valve or automatic expansion valve), suction line, and returning
to condensing unit.
The line sizes and refrigerant charges are listed as follows.

NOTES: THE VALVES MUST BE IN THE MIDDLE POSITIONS TO READ
PROPERLY.
Low side pressure: 33 psig.
