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 ceiling-mounted cooling systems WM-2500~12000SSD
and WM-2500~12000SSD-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.
 SSD 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.
 SSD 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.
 SSD condensing units can be located away from the wine cellars up to 75 ft
so that noise and compressor vibration are isolated.

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.
The specifications are listed as follows:

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.

1. Condenser Coil Cleaning
 Clean the condenser coil regularly. Coil may need to be cleaned at least
every 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 cellar
under high humidity conditions.

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.

2. Temperature Controller and Air Probe Location
1) The temperature controller can be mounted either inside or outside the wine
cellar, but the air probe must be located inside.
2) 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.
3) 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.
3. Evaporator Unit Location

- 19 -
1) The WM-25~120SFCD evaporator units shall be installed for ceiling mount
with the supply air toward horizontal and return air on the bottom. The units
may be recessed in the ceiling with short curved rectangular ducts in air
supply, but the air flow CFM must be checked.
2) For a direct blow application, air supply shall be unobstructed minimum 12”.
For a deflector application, leave 2” clearance for air supply.
Air return shall be unobstructed minimum 6”.
3) There is a gravity drain system, 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.
If rise-up is necessary, a condensation pump must be used.
4. Condensing Unit Location
CAUTION Low ambient condition kit is required if the temperature will be
below 50°F.
1) Place the condensing units WM-250~1203SCUR in a properly ventilated
location. Otherwise, heat exhausted by the condensing unit will build up and
the cooling system will not operate properly.
2) Condensing unit shall be elevated to avoid possible flooding and shaded from
direct sun. It shall not be exposed to temperatures higher than 110 °F or
lower than 50 °F.
3) Leave minimum 5 ft clearance for the air exhaust side and leave minimum 1
foot clearance for the air intake side.
5. Refrigeration Piping and Leak Testing
NOTE
The line connector sizes of liquid filter and indicator, the valve
connector sizes of condensing unit or the line connector sizes of
evaporator unit may not be the same as the listed refrigeration line
sizes.
If the condensing unit is installed above the evaporator unit, use
the suction line one size smaller.
Expansion and solenoid valves have been installed on the liquid
line in the evaporator unit.
The line sizes and refrigerant charges are listed as follows.
