Installer’s Instruction

Federal law requires that WINEMATE split cooling systems be
installed by an EPA certified refrigeration technician.

WINEMATE split system is shipped as components and is ready for use only
after a certified refrigeration technician has properly installed, charged 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 WM-150SCU 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 shall be elevated to avoid possible flooding and shaded
from direct sun. It shall 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 WM-15SFC evaporator unit is installed for ceiling mount with the air
supply towards horizontally and air return on the bottom.

• The WM-19SFC evaporator unit is installed for wall mount with the air
supply towards top and air return on the sides.

• Supply and return air flow from the evaporator unit shall be unobstructed
for at least 1 foot.

• There is a gravity drain line so that it can not be installed above the
evaporator unit. Otherwise a condensation pump must be used.

3. Refrigeration Piping and Charging

NOTES: ALWAYS USE THE SUPERHEAT AND SUBCOOLING,
PRESSURE READINGS TO CHARGE REFRIGERANT PROPERLY, THE
LISTED CHARGES ARE FOR REFERENCE ONLY.

• 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), returning to suction line
and condensing unit.

• The subcooling at the condensing unit shall be around 10°F. The charge
may be complete when there are no more bubbles forming in the sight
glass.

• The evapor ator superheat is set around 8-10 °F for a 10 °F TD system at
factory.

• Low side pressure: around 33 psig

• High side pressure: 130 -150 psig at 75 -90 °F ambient temperatures

4. Pressure, Superheat and Subcooling Readings

NOTES: THE SERVICE VALVES MUST BE IN THE MIDDLE POSITIONS TO
READ PROPERLY.

Complaint Possible Causes

a. High suction pressure and low head pressure
b. High suction pressure and low head pressure
Low superheat and low subcooling

a. Compressor may be bad
b. Expansion valve opened, too

much oil
