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 packaged central-ducted cooling systems WM-4500~12030DS &
WM-4500~12030DS-LA are designed to provide a cold temperature 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.
• It is self-contained ready for use and no additional refrigeration tubing is
required in the field.
• The cooling systems are designed to provide chilled air to a wine cellar
through insulated ducts to provide quieter operation and better installation
flexibility.
• The cooling systems can be installed up to 25 ft away from the cellar since
the back-curved impeller fans are so powerful to run a total duct length of 50
ft.
• The cooling systems can be installed both outdoors and indoors.
Fig. 1 DS Packaged Central-Ducted Cooling System
CAUTION
If the cooling unit operates below 50°F, a low ambient
condition kit will be required.
NOTE
The cooling capacity is determined using 55°F cellar
temperature, 75°F cellar ambient temperature, 90°F
condensing unit ambient temperature, R13 interior insulation
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.

User’s Troubleshooting
This Troubleshooting Chart is not prepared to replace the training required for a
professional refrigeration service person, not is it comprehensive.
Complaint
Possible Causes
Response
1. Unit not running
a. Power cord not plugged
b. No power from supply
c. Incorrect or loose wirings
d. Low voltage
e. Setting higher than ambient
temperature
f. Waiting for cut-in
g. Defrost light blinking

i. Call service for diagnosis
2. Unit not
starting, but
temperature
rising high
a. Anti-short cycle
a. Reset AC
3. Temperature
fluctuating
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.

• There is a gravity drain system used, so the unit shall be installed level or with
a slight slope downward the drain connection and the drain line shall be
installed slope down toward the drain.
4. Temperature Controller and Air Probe
• The temperature controller can be mounted either inside or outside the wine
cellar, but the air probe must be located inside the wine cellar or the return
duct.
• The air probe shall be located in the wine cellar 5 ft above the floor or the air
return area, but it shall not be located in the air supply area or other areas
where air is not circulated.
• Air probe can be pulled out of the temperature controller up to 5 ft. If
additional wires are necessary, 18 gauge wires may be used to extend the air
probe.
• If the air probe is installed in a return duct, the evaporator fans shall be
running at all times. Meanwhile due to the temperature differential the air
probe calibration should be done to maintain the proper wine cellar
temperature.
5. Insulated Duct and Drain Line Installation
• Cold air supply and cellar air return ducts can be up to a total length of 50 ft.
• Hot air exhaust and fresh air intake ducts can be up to a total length of 50 ft.
