Cellar Construction Guide
This is only a guide and shall be considered as the minimum requirements.
All interior walls, ceilings and floors shall have a vapor barrier and a minimum of
R13 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 insulation. All joints, door frames, electrical outlets or switches and any pipes
or vents that go through the cellar shall be sealed to prevent air and moisture leaking
into the cellar. Concrete, rock, and brick are not insulations or vapor barriers. Doors
shall be of a minimum size, insulated to at least R13 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 cellar shall not exceed the temperature of the cellar by more than 25 °F. No
cellar walls 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
cellar 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 cellar. Symptoms of this
condition are; cooling unit runs all the time with only a slight reduction in temperature
and/or water overflows from the cooling 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 cellar. Please be aware that moisture can pass through
solid concrete, paint and wood. Often a newly constructed cellar 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.

Features and Specifications
• WINE~MATE split low-profile cooling systems WM-2520~8520SSL and WM-
2520~8520SSL-LA are designed to provide a cold environment between 50~65
°F with a humidity range within 50~70% RH for a properly insulated wine cellar.
• These temperature and humidity ranges are optimized for long term storage of
wine like that in natural caves.
• SSL evaporator units can be installed on the ceiling in a small cabinet or
room. The evaporator units provide low profile and whisper quiet operation.
• SSL cooling systems consist of a remote condensing unit and an evaporator unit
and they are connected by a liquid line and an insulated suction line.
• SSL condensing units can be located away from the wine cellars up to 75 ft so
that noise and compressor vibration are isolated.
Fig. 1 SSL Split Low-Profile Cooling System

-5-
CAUTION
If the condensing unit will operate below 50°F, install a low
ambient condition kit.
NOTE
The cooling capacity is determined under 55°F cellar temperature,
75°F cellar ambient temperature and 90°F condensing unit ambient
temperature, with R13 interior and R19 exterior insulations. Higher
ambient temperatures or lower insulations will cause reducing
capacity and the cellar temperature may not be maintained at 55°F.

7. How to calibrate the air probe
If the actual cellar temperature differs from the setting temperature, set
parameter ot = actual cellar temperature minus set-point.
8. How to adjust defrost settings
In case there is excessive frost, the parameters FnC = C-y, idF = 4 and MdF =
20 can be used to avoid frost.
9. How to adjust the humidity
The parameter Fon is used to adjust the humidity in the wine cellar. Higher Fon
results in higher relative humidity. Use a separate hygrometer to monitor the
humidity.
10. How to set alarm call
1) Speech notice will be sent to your phones when the cellar temperature is ALU
higher or ALL lower than the set-point Set.
2) In order to test the call function, set parameters Ald = 0 and dAO = 0. After
testing, set Ald = 60 and dAO = 23.
11. How to set cellar heater
The heater turns on at SAA minus Shy; the heater turns off at SAA.
NOTE
Use a forced air heater to warm up the wine cellar.
If there is a thermostat on the heater, bypass it or set thethermostat
at the highest level.
If the heater runs more than 10 A current, use a 120VAC coil
contactor.

Care Guide
In general, always unplug system or disconnect power while doing care.
1. Condenser Coil Cleaning
• Clean the condenser coil regularly. Coil may need to be cleaned at leastevery
6 months.
• Use a vacuum cleaner with an extended attachment to clean the coil when it
is dusty or dirty.
2. Condensate Removing
• Remove the excessive condensate if it is accumulated in the wine cellarunder
high humidity conditions.

a. Air probe
a. When using an air probe, the
wine bottle temperature is mainly
controlled by the average air
temperature. If the set-point is 55°F
with the differential 4F, the cooling
unit turns on at 59°F of air
temperature (It may be higher than
59°F if it is in anti-short cycle or
defrost) 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
fluctuating.
