Feature Description
• Wine-Mate split cooling systems VINO1500SSW and 2500SSW 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.
• SSW units consist of a condensing unit and an evaporator unit, and they
are connected by a liquid line and an insulated suction line.
• The SSW condensing units can be located away from the evaporator units
and wine cellars as far as 50 feet, which will bring you quiet operation.
• The SSW evaporator units are designed for installation between two wall
studs, making them an ideal choice for small and medium wine rooms.

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.
WINE-MATE 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 units WM150SCU and 250SCU 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 WM15-25SFCW evaporator units shall be installed for wall mount with
the air supply on the top and air return on the bottom.
- 6 -
Download from Www.Somanuals.com. All Manuals Search And Download.
• 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. 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
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), suction line, and returning
to 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 evaporator’s constant pressure expansion valve is set around 38-
40°F at factory. This pressure setting gives a dew point to maintain the
humidity for storing wine.
• The superheat at the evaporator unit shall be around 9-18°F under low
and high load at 75°F ambient temperature.
• Low side pressure: 33 psig
• High side pressure: 130 -150 psig at 75 -90 °F ambient temperatures

Temperature Control & Humidity Adjustment
1. Temperature Setting
• Set the temperature at 55 °F for the optimum aging of wine
• On initial start-up, the time required to reach the desired temperature
will vary, depending on the quantity of bottles, temperature setting
and surrounding temperature.
• Allow 24 hours to stabilize the temperature for each new temperature
setting operation
2. Use of the Digital Controller
Fig. 3.1 Digital Controller
1) Display
During normal operating conditions, the display shows the value measured by
the air regulation probe. In case of active alarm, the temperature flashes
alternately to the code alarm.

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.
• Unplug the system or disconnect power.
• Use a vacuum cleaner with an extended attachment to clean the coil when it
is dusty or dirty.
• Plug cooling system or reconnect power.
2. Moisture Removing
• Remove the extra condensate if it is accumulated in the wine cellar at high
ambient temperature and humidity.

the cooling unit turns on at 59°F of air
temperature and turns off at 55°F of air
temperature.
The

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
