Features and Specifications
•CELLARTEC ducted system CellarTec 1/3-3/4 Ton-DS are designed and
used to provide a cold temperature between 50~65 °F for a properly
insulated wine room at a normal environment.
•The wine room will maintain humidity of 50~70% RH even when the
environment becomes dry and humid. These temperatures and humilities
are optimized for long term storage of wine.
•The DS ducted systems are designed for both outdoor and indoor
installation.
•Back-curved impeller fans are good for total 50 ft long duct to cut the
operation noise.
•Self-contained ready for use with no extra refrigeration tubing in the field.

Cellar Construction
This is only a guide and shall be considered as minimum requirements.
All interior walls and floors shall have a vapor barrier and a minimum of R11
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 the
insulation. All joints, door frames, electrical outlets or switches and any pipes or
vents that go through the enclosure shall be sealed to prevent air and moisture
leakage into the room. Concrete, rock, and brick are not insulation or vapor
barriers.
Doors shall be of a minimum size, insulated to at least R11 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 enclosure shall not exceed the temperature of the enclosure by
more than 25 °F. No enclosure wall 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 enclosure 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 enclosure. Symptoms of
this condition are; unit runs all the time with only a slight reduction in temperature
and/or water overflows from the 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 enclosure. Please be aware that moisture can pass
through solid concrete, paint and wood. Often a newly constructed room 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.

Installer’s Instruction
Federal law requires that CELLARTEC ducted cooling systems
be installed by an EPA certified refrigeration technician.
CELLARTEC ducted system is shipped ready for use only after a certified
refrigeration technician has properly installed the system. Proper installation is
critical. Apex can only warrant the quality of the components. The installation of
the system must be warranted by the installer. Installation of the system must be
done in accordance with all state and local building and electrical codes.

1. Location
•Place the 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.
•Cooling 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 (optional low ambient kit available).
•Leave minimum 5 feet clearance for hot air exhaust and leave minimum 1
foot clearance for the fresh air intake.
•There is a gravity drain line and the unit shall be installed level or with a
slight angle toward the drain connection.
•Supply air flow shall be unobstructed for at least 12” for free installation or
2” for deflector installation and return air shall be unobstructed for 6”.
•Overall combined supply + return or exhaust + intake duct length can be
up to 50 ft long.
2. Mounting
•The unit must be mounted on a floor or slab that is level and strong
enough to support up to 300lb.
•There are six ½” bolts required to secure the unit base.
3. Customer Wiring
•Use 14 AWG wires.
•If it is CellarTec 1/3 Ton-DS without low ambient kit, go to the next step.
Connect wires in the outlet box of the condensing unit to the power lines
•Connect wires in the outlet box of the evaporator unit to the temperature
controller and then connect the controller to the power lines.
4. Thermostat and Air Sensor(USE 18 GAUGE THERMOSTAT WIRE)
•The thermostat with a built-in air sensor can be installed in the wine room
5 ft above the floor in an area with good air circulation at average temp.
•If the thermostat is mounted outside the wine room, a remote air sensor is
required inside the wine room. The air sensor can be located in a well
circulated or in the return air area, but not the supply air or air dead area.
•If air sensor is in a return duct, the evaporator fans shall be running all the
time. Due to the temperature differential the temperature setting needs to
be adjusted in order to maintain the proper wine room temperature.
5. Air Flow (Evaporator unit)
•If the overall duct length is less than 50ft, it is necessary to check the air
flow to meet the specified CFM. It may use fan speed control to adjust the
system refrigeration performance to achieve 8-10°F differential between
return air and supply air while wine room temperature is maintained 55°F.
Turn the control knob clockwise to decrease the air flow or counter-
clockwise to increase the air flow.

6. Intake and Exhaust Guards
•If the intake and exhaust are located outdoor, protection guards may be
required.

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

Service Guide
CAUTION:
•ALWAYS USE THE SUPERHEAT AND SUBCOOLING, PRESSURE
READINGS TO CHARGE REFRIGERANT PROPERLY, THE LISTED
CHARGES ARE FOR REFERENCE ONLY.
•CHARGE 15% MORE REFRIGERANT IN THE SUMMER IF THE UNIT IS
EQUIPPED A LOW AMBIENT CONDITION KIT
NOTES:
•THE VALVE CONNECTION SIZES OF CONDENSING UNIT AND THE LINE
CONNECTION SIZES OF EVAPORATOR UNIT ARE NOT NECESSARY
THE SAME AS THE ABOVE SPECIFIED LINE SIZES.
•IF THE CONDENSING UNIT IS INSTALLED ABOVE THE EVAPORATOR
UNIT, USE THE SUCTION LINE ONE LISTED SIZE SMALLER.
•EXPANSION AND SOLENOID VALVES ARE INSTALLED ON LIQUID LINE.
1. Refrigeration Piping, Evacuating, Charging and Starting
•The installation order starts from condensing unit (including the receiver,
discharge valve), liquid line filter-drier, moisture-liquid indicator/sight glass,
liquid line, to evaporator unit (including liquid line connection, solenoid
valve, expansion valve, and suction line connection), returning to insulated
suction line, suction valve and then condensing unit.
•Use inverted siphons to prevent liquid from flooding back to the
compressor and aid oil returning to the compressor.
•Charge the system after pipe brazing, leak testing and evacuating. Liquid
must always be charged into the hide side.
•It may use fan speed control to adjust the air flow to achieve the specified
CFM. Turn control knob clockwise to the lowest speed position, locate and
adjust the minimum speed setting (on the side or front) with screw driver.
Rotate the setting clockwise to decrease minimum speed or counter-
clockwise to increase minimum speed). The minimum speed should be
adjusted until it supplies the required CFM. The fan will run from this
preset minimum speed to full speed with the control knob at lowest and
highest speed position.
•The subcooling at the condensing unit shall be around 10° F. The charge
may be complete when there are no more bubbles forming in the sight
glass.
•Head pressure: 125-150 psig at 70 -90 °F ambient temperatures.
•The evaporator’s constant pressure expansion valve is set around 35-
40°F at factory. This pressure setting gives a dew point to maintain the
humidity for storing wine.
•Suction pressure: Adjust the AXV to 30-35 psig.
•The temperature split between return air and supply air shall be 8-10°F at
55°F wine room temperature.

- 14 -
•The superheat at the evaporator unit shall be around 9-18°F under low -
high heat load at normal ambient temperatures.
•If the superheat is high, check the subcooling first to know if the refrigerant
charge is sufficient. If the charge is not sufficient, add more refrigerant. If
the charge is good, then increase the evaporator suction pressure by
turning the hex nut (5/16”) clockwise.
•If the superheat is low, then decrease the evaporator suction pressure by
turning the hex nut (5/16”) counter-clockwise.
