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 morethan 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
ï WM-2500~12000SSDWC split water-cooled ceiling-mounted cooling systems
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.
ï These temperature and humidity ranges are optimized for long term storage
of wine like that in natural caves.
ï SSDWC evaporator units can be installed on the ceiling in the center of a
wine cellar. The evaporator units provide two way air supply for better
operation.
ï SSDWC 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.
ï SSDWC condensing units are water cooled so that exhaust ventilation is not
needed.
ï SSDWC condensing units can be located away from the wine cellars up to 75
ft so that noise and compressor vibration are isolated.
Fig. 1 SSDWC Split Water-Cooled Ceiling-Mounted Cooling System

CAUTION
The condensing unit must operate above 32°F ambient
temperature.
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 the
thermostat 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 Water Line Cleaning
• To clear any sediment that may accumulate, the water regulating valve may
be manually flushed.
• Insert screwdrivers under both sides of the valve spring guide and lift upwards
to flush.
2. Condensate Removing
• Remove the excessive condensate if it is accumulated in the wine cellar at
high humidity conditions.

3. Temperatur
efluctuating
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.
