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 low ambient kit for 20 °F).
2. Evaporator Unit
•The WM25-85SFCD evaporator units should be installed for ceiling mount
with air supply on both sides and air return on the bottom.

- 7 -
•Supply and return air flow from the evaporator unit should be unobstructed
for at least 1 foot.
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
•If equipped with a TXV, the evaporator superheat is set around 8 °F for a
10 °F TD system at factory.
•If equipped with an AXV, the valve is set around 38-40°F at factory.
•The charge may be complete when there are no more bubbles forming in
the sight glass. The subcooling at the condensing unit is around 10°F and
the superheat at the evaporator unit is around 8°F at 75°F ambient
temperature.
•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 & Humidity Adjustment
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 VTSTAT controller
Fig. 3.1 Digital Controller
Fig. 3.2 Dip Switch Setting

- 14 -
1) Set Point
Rotate the circular selector in correspondence with the arrow placed nearby. The
selector represents 14°F to 68°F (-10°C to +20°C) for medium temperature
models. “10” is the coldest setting, “1” is the warmest. Use the medium temp
setting and place the dial at number 3.
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 VTSTAT 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.

professional refrigeration service person, not is it comprehensive
Troubleshooting Chart
Complaint Possible Causes Response
1. Unit not running
p. No power
q. Power cord unplugged
r. Defrost light blinking
s. Compressor light blinking
t. Setting higher than ambient
temperature
u. Low voltage.
v. Incorrect or loose wirings.
p. Check power at receptacle & fuses
q. Check for power cord plug
r. Unit is under defrost mode
s. Unit waits for anti-short cycle delay
t. Lower temperature setting
u. Contact an authorized electrician
v. 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.
3. Temperature too high
a. Setting too high
b. Improper room insulation & seal
c. Room too large
d. Ambient temperature too high
e. Exhaust restricted
f. Malfunctioning fans
g. Improper evaporator or condenser
airflow
