Important Safety Information
WARNING:
•DO NOT USE A GROUND FAULT INTERRUPTER (GFI).
•A DEDICATED 20 OR 30 AMP CIRCUIT IS REQUIRED (2500-4500SSR OR
6500SSR).

Features and Specifications
•Wine-Mate split cooling systems VINO2500-6500SSR 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.
•SSR units consist of a condensing unit and an evaporator unit, and they
are connected by a liquid line and an insulated suction line.
•SSR condensing units can be located away from the evaporator units and
wine cellars as far as 50 ft, which will bring you quiet operation.
•The SSR evaporator units are designed for installation inside a wine rack
or between two ceiling joists, making them an ideal choice for small and
medium wine rooms. There are also multiple air inlet and outlet doors for
different installations.

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, 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 units WM250-650SCU 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.
2. Discharge/Suction Valve Operation (Condensing unit)
Back Position: Normal operation, process and manometer port closed
Front Position: Liquid/suction line connection closed
Middle Position: All ports open for evacuation, charge and manometer reading

3 – Liquid Line or Suction Line; 4 - Pressure Control
3. Evaporator Unit
•The WM25-45SFCR evaporator units shall be installed for rack mount with
the air supply from the left front, top or side and air return on the right
front, top or side.
•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”.
•Grille can be used to cover the supply and return, and also 2-3 ft long duct
can be added.
•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. Air Sensor and Temperature Controller
•The air sensor can be located in the wine room 5 ft above the floor or the
return air area, but not the supply air area or air dead area.
•If the temperature controller is mounted outside the wine room but the air
sensor is located inside the wine room, use 18 gauge wires to extend the
air sensor if needed.
5. 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 LISTED LINE SIZES.
•IF THE CONDENSING UNIT IS INSTALLED ABOVE THE EVAPORATOR
UNIT, USE THE SUCTION LINE ONE LISTED SIZE SMALLER.
EXPANSION AND SOLENOID VALVES 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.

- 11 -
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) It may use fan speed control to adjust the air flow to achieve the specified
CFM. Turn control knob clockwise to the lowest speed position, locate and
adjust the minimum speed setting (on the side or front) with screw driver.
Rotate the setting clockwise to decrease minimum speed or counter-
clockwise to increase minimum speed). The minimum speed should be
adjusted until it supplies the required CFM. The fan will run from this
preset minimum speed to full speed with the control knob at lowest and
highest speed position.
Fig. 9 Fan Speed Control
6) 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.
7) Head pressure range: 125 ~ 150 psig at 70 -90 °F condensing unit
ambient temperature.
8) The evaporator’s constant pressure expansion valve is set around 30 ~ 35
psig (35 ~ 40°F) at factory. This pressure setting gives a dew point to
maintain the humidity for storing wine.
9) The temperature split between return air and supply air shall be 8 ~ 10°F
at 55°F wine room temperature.
10)Again, must verify if the superheat at the evaporator unit is around 9 ~
18°F at 50 ~ 65 °F wine room temperature with a normal condensing unit
ambient temperature.
11)If the superheat is high, check the subcooling first to know if the refrigerant
charge is sufficient. If the charge is not sufficient, add more refrigerant. If
the charge is good, then increase the evaporator suction pressure by
turning the hex nut (5/16”) clockwise.
12)If the superheat is low, then decrease the evaporator suction pressure by
turning the hex nut (5/16”) counter-clockwise.

13)Both discharge and suction valves must be in the back positions before
disconnecting evacuating and pressure gauges.
