Important Safety Information
•DO NOT USE A GROUND FAULT INTERRUPTER (GFI).
•A DEDICATED 20 AMP CIRCUIT IS HIGHLY RECOMMENDED.
- 2 -

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.
•SSR 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.
The dimensions and capacity 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 crankcase heater for 20 °F).
2. Evaporator Unit
•The WM25-45SFCR evaporator units should 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.
- 5 -

•Supply and return air flow from the evaporator unit should be unobstructed
for at least 1 foot.
3. Refrigeration Piping and Charging
•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 charge may be complete when there are no more bubbles forming in
the sight glass.
•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.

Temperature Control
1. Temperature Setting
•Set the temperature at 55 °Ffor 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 952884 controller

Dip Switch Setting

1) Set Point
Rotate the circular selector in correspondence with the arrow placed nearby. The
selector represents -33°F to 50°F (-35°C to +10°C) for low temperature models,
and 14°F to 68°F (-10°C to +20°C) for medium temperature models. “10” is the
coldest setting, “1” is the warmest.
2) Differential
It is possible to modify the differential from 1°F minimum to 12.5°F maximum.
Simply shift the first two dip-switches to the ON or OFF position according to the
wanted value.
3) Defrost management and setting
A defrost can be activated manually, by pressing the “man. def.” button, or
cyclically, the interval set by the “def.intvl” rotary switch at the top left with respect
to Set Point selector. The interval can be selected from 1 to 12 hours in 1 hour
steps. If the selector is positioned on the “0”, the cyclic defrost is disabled.
Note: manual defrost reinitializes the time required for successive cyclic
defrosting. The selections are effective beginning from the successive cycle. For
an immediate effect, it is necessary to turn power to the 952884 off for a few
seconds.
It is possible to choose between an electric defrost (the compressor is
deactivated and the defrost relay is activated) and a hot gas defrost (both the
compressor and the defrost relay are activated); The defrost termination, can
take place by time (from 1 to 60 min.) or by temperature (from 0 to 86°F) if the
defrost sensor is utilized for the correct programming). If the defrost sensor is
disconnected, interrupted or breaks down for any reason, the defrost terminates
after a maximum time of 90 minutes if it is resistance-based, or 40 minutes if it is
hot-gas based.
The instrument stores the defrost state every 15 minutes to allow restart after
power loss.
4) Compressor safety function
If the function is enabled, a minimum three minute interval is ensured between
deactivation and successive restart of the compressor.
If the function is enabled, the compressor is not energized for three minutes after
controller power up.
The function is also active in hot-gas defrost mode.

2) Alarm Signals
2.1 Code Description
2.2 Alarm Recovery
Probe alarms P1”, start a few seconds after the fault in the related probe; they
automatically stop a few seconds after the probe restarts normal operation.
Check connections before replacing the probe. Temperature alarms “HA”, “LA”
automatically stops as soon as the temperature returns to normal value. Alarm
“CA” (with i1F=PAL) recovers only by switching off and on the instrument.
3) Temperature Set-Point
3.1 How to see the set-point
1. Push and immediately release the SET key: the display will show the Set-point
value;
2. Push and immediately release the SET key or wait for 5 seconds to display the
probe value again.
3.2 How to change the set-point
- 12 -
1. Push the SET key for more than 3 seconds to change the Set point value;

2. The value of the set point will be displayed and the “°C” or “°F” LED starts
blinking;
3. To change the Set value, push the o or n arrows within 10s.
4. To memorize the new set point value, push the SET key again or wait 10s.
4) Manual Defrost
Push the DEF key for more than 2 seconds and a manual defrost will start.

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.

Troubleshooting Chart
- 15 -
Complaint Possible Causes Response
1. Unit not running
j. No power
k. Power cord unplugged
l. Defrost light blinking
m. Compressor light blinking
n. Setting higher than ambient
temperature
o. Low voltage.
p. Incorrect or loose wirings.
j. Check power at receptacle & fuses
k. Check for power cord plug
l. Unit is under defrost mode
m. Unit waits for anti-short cycle delay
n. Lower temperature setting
o. Contact an authorized electrician
p. Check all wirings and connections
2. 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.
