Features and Specifications
•Wine-Mate split cooling systems VINO1500SS and 1900SS are 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 SS units consist of a condensing unit and an evaporator unit, and they
are connected by a liquid line and an insulated suction line.
•The condensing units can be located away from the evaporator units and
wine cellars as far as 50 ft, which will bring you quiet operation.
•VINO1500SS evaporator unit can be installed on the ceiling in a wine cellar
and VINO1900SS evaporator unit can be installed on the wall.
The dimensions (in inches) and capacities are specified as follows:

Cellar Construction
This is only a guide and shall be considered as minimum requirements.
All interior walls and floors shall have a vapor barrier and a minimum of R11
insulation. All exterior walls and ceiling shall have a vapor barrier and a minimum
of R19 insulation. The vapor barrier shall be installed on the warm side of the
insulation. All joints, door frames, electrical outlets or switches and any pipes or
vents that go through the enclosure shall be sealed to prevent air and moisture
leakage into the room. Concrete, rock, and brick are not insulation or vapor
barriers.
Doors shall be of a minimum size, insulated to at least R11 and tightly sealed
with high quality weather stripping. Be sure to seal the bottom of the door and fill
gap between the door’s frame and wall before installing the cap molding.
In order to maintain 55 °F in the wine cellar, the ambient temperature
surrounding the enclosure shall not exceed the temperature of the enclosure by
more than 25 °F. No enclosure wall shall receive direct sun or strong wind.
Lighting shall be of low wattage, with a timer to insure lights are not left on when
the enclosure is not occupied.
The cooling system will not be able to maintain the proper temperature if fresh
moisture-laden air is constantly being introduced to the enclosure. Symptoms of
this condition are; unit runs all the time with only a slight reduction in temperature
and/or water overflows from the unit. Because of the temperature difference
between the inside and outside, very small cracks can allow large amounts of
outside air to enter into the enclosure. Please be aware that moisture can pass
through solid concrete, paint and wood. Often a newly constructed room contains
fresh wood, paint, concrete and other building materials. These materials contain
large amounts of moisture. When placed into operation in this type of
environment, the system will work harder to remove this extra moisture resulting
in increased “run” time.

Installer’s Instruction
Federal law requires that WINE-MATE 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, evacuated,
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 and electrical 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. 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.
•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 50 °F (optional low ambient kit available).
•Leave minimum 5 ft clearance for the exhaust side and leave minimum 1
foot clearance for the fresh air intake side.
CAUTION:
IF THE CONDENSING UNIT IS EQUIPPED WITH A LOW AMBIENT
CONDITION KIT, DO NOT TURN ON THE COMPRESSOR UNTIL THE
CONDENSING UNIT HAS BEEN POWERD FOR 24 HOURS.

3. Evaporator Unit
•The WM-15SFC evaporator units shall be installed for ceiling mount with
the air supply towards horizontally and air return on the bottom.
•The WM-19SFC evaporator unit shall be installed for wall mount with the
air supply towards top and air return on the sides.
•Supply air flow shall be unobstructed for at least 12” for free installation or
2” for deflector installation and return air shall be unobstructed for 6”.
•There is a gravity drain line and the unit shall be installed level or with a
slight angle toward the drain connection. If rise-up is needed, a
condensation pump must be used.

4. Piping, Evacuating, Charging and Starting
CAUTION:
•ALWAYS USE THE SUPERHEAT AND SUBCOOLING, PRESSURE
READINGS TO CHARGE REFRIGERANT PROPERLY, THE LISTED
CHARGES ARE FOR REFERENCE ONLY.
•CHARGE 15% MORE REFRIGERANT IN THE SUMMER IF THE UNIT IS
EQUIPPED WITH A LOW AMBIENT CONDITION KIT.
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 ABOVE SPECIFIED LINE SIZES.
•IF THE CONDENSING UNIT IS INSTALLED ABOVE THE EVAPORATOR
UNIT, USE THE SUCTION LINE ONE LISTED SIZE SMALLER.
•EXPANSION VALVE AND SOLENOID VALVE ARE INSTALLED ON
LIQUID LINE.
1) The installation order starts from condensing unit (including receiver and
discharge valve), liquid line filter-drier, moisture-liquid indicator/sight glass,
liquid line, to evaporator unit (including liquid line connection, solenoid
valve, expansion valve, and suction line connection), returning to insulated
suction line, suction valve and then back to condensing unit.
2) Use inverted siphons to prevent liquid from flooding back to the
compressor and aid oil returning to the compressor.
3) Both discharge and suction valves must be in the middle positions during
evacuating and charging.
4) Charge the system after pipe brazing, leak testing and evacuating. Liquid
must always be charged into the hide side.
5) 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 liquid
indicator.
6) Head pressure range: 125 ~ 150 psig at 70 ~ 90 °F condensing unit
ambient temperature.
7) The evaporator superheat is set around 8 ~ 10 °F at factory.
8) Suction pressure: 30 ~ 35 psig.
9) The temperature split crossing the evaporator shall be 8 ~ 10°F at 55°F
wine room temperature.
10)Both discharge and suction valves must be in the back positions before
disconnecting evacuating and pressure gauges.

2.Displaying
Temperature
fluctuating
a. Air sensor When using an air sensor, the wine
bottle temperature is mainly controlled
by the average air temperature. If the
set-point is 55°F with a differential 4 °F,
the cooling unit turns on at 59°F of air
temperature and turns off at 55°F of air
temperature. The average air
temperature is 57°F, and then the wine
temperature is around 57+/-0.5°F. The
air is light enough to change so quickly
that it maintains relatively constant
average temperature that would prevent
wine bottle temperature from varying.
