Placement
CellarPro 3200 and 4200 Series cooling units are designed to be installed THROUGH THE
WALL, so that the rear and the front of the cooling unit DO NOT SHARE THE SAME AIR
SPACE.
The rear of the cooling unit must be installed in a space that is at least as large as the wine
cellar unless the rear intake and exhaust are ducted. Both the front and the rear of the
cooling unit require a minimum clearance of 8 inches.
These units also can be placed completely INSIDE or OUTSIDE the cellar when used in
combination with our duct kits.
Ambient Environment
3200VSi / 4200VSi - designed for internal use only (ie sheltered from outdoor
weather), the rear of the unit can be exposed to temperature conditions ranging
from 40 to 115°F.
3200VSx / 4200VSx – designed for external use, the rear of the unit can be
exposed to temperature conditions ranging from 40 to 115°F. Refer to the
Installation section for additional requirements for outdoor exposures.
PLEASE NOTE: With our (optional) crankcase heater, all of our cooling units can
be used in environments down to 20°F.
CellarPro cooling units are not designed to heat the cellar space, so if
temperatures inside the cellar drop below proper wine storage temperatures, the
cooling unit cannot create heat inside the cellar.
Insulation
CellarPro cooling units are
designed to be installed
inside wine cellars that have
proper insulation, moisture
barriers and an airtight seal
from the environment
outside the cellar. Interior
walls and floor should
have a minimum of R-11
insulation, and a vapor barrier
on the warm side of the
insulation. The ceiling should
have a minimum of R-19




insulation and a vapor barrier on the warm side of the insulation. Doors also
should be insulated and tightly sealed with weather stripping around
the perimeter of the door. Surface-mounted fixtures are
reco mmended over recessed lighting, which can allow air to leak into the
cellar.
It is important that all walls, joints, doors and windows, electrical outlets
and/or switches, pipes, vents and light fixtures be sealed to prevent air and
moisture from entering the cellar. If there is a leak in the cellar, the cooling unit will
build up excess condensation.
CellarPro 3200 and 4200 cooling units are equipped with a condensate
management system, which includes a stainless steel pan, a thermostatically-
controlled electric heating element, and an overflow drain at the rear of the
cooling unit.
We strongly recommend that the overflow drain line (shipped loose with the
cooling unit) be connected to the overflow drain (as shown in the installation
section), and that the cooling unit be mounted to tilt slightly backwards, so that
any overflow condensate is channeled safely to the overflow drain line. In addition,
we recommend turning on the electric heating element to burn off excess
condensate that accumulates in the stainless steel pan during the initial cooling of
the cellar and during high run-times, as well as in high-humidity environments.
Fan Speeds
Your fan speed setting will depend on the thermal load on the wine cellar, and
the resulting BTU that is required to cool and maintain your wine cellar at the
desired temperature.
Ventilation
Adequate ventilation is critically important for the proper operation of your
CellarPro cooling unit.
OUTSIDE THE CELLAR
(At the rear of the cooling unit)
Condenser Air Exhaust. CellarPro 3200 and 4200 Series cooling units create
significant hot air which must be exhausted into an appropriately-sized space
in order for the heat to dissipate. If the space is constrained and/or too small,
the heat will not dissipate. In this event, the cooling unit will be forced to re-
circulate its hot air exhaust and/or the static pressure will back up the cooling
unit. If this happens, the cooling unit’s ability to create cold air inside the cellar
will be compromised.


8
Condenser Air Intake. The condenser coils require access to cool air in order
for the cooling unit to produce cold air. In addition, the cooling unit must be
installed so that, after its installation, the condenser coils are accessible for
periodic cleaning or replacing of the filter.
The rear of the cooling unit must be installed in a space that is at least as large as the
wine cellar unless the rear intake and exhaust are ducted. Both the front and the rear
of the cooling unit require a minimum clearance of 8 inches.
Ducting. CellarPro 3200 and 4200 units allow the condenser air intake and
exhaust each to be ducted up to 50 equivalent feet with 8” diameter ducting, or
100 equivalent feet with our auxiliary fan and 8” diameter ducting. We offer two
rear duct kits (sold separately) that attach to the rear of the cooling unit.
INSIDE THE CELLAR
(At the front of the cooling unit)
Evaporator Air Intake . CellarPro cooling units should be mounted at the
highest point inside wine cellars, so that warm air – which rises – will be the first to
pass over the evaporator coils, which are located behind the grill on the face of
the cooling unit. When the warm air passes across the evaporator coils, heat is
removed the air, and the resulting cold air is exhausted into the cellar. To ensure
proper airflow, minimum clearance of 12” is required in front of the cooling unit.
Evaporator Air Exhaust. Cold air is exhausted at the top front of the cooling
unit. Because CellarPro cooling units are located at the highest point inside
wine cellars, the cold air exhaust eventually will drop to the bottom of the cellar.
To ensure proper airflow and reduce temperature stratification inside the cellar,
the space in front of the cold air discharge should be clear of any obstructions,
including wine bottles, wine racks, etc.
Ducting. CellarPro 3200 and 4200 units allow the evaporator air intake and
exhaust each to be ducted up to 50 equivalent feet with 8” diameter ducting.
We offer a front duct kit (sold separately) that attaches to the front of the
cooling unit.
We also offer a remote control panel kit that can be installed remotely (up to 10
feet) from the cooling unit, either inside or outside the cellar, and a bottle probe
(10 foot cord) that can be plugged into the cooling unit.

Power Requirements
CellarPro cooling systems should be plugged into a dedicated outlet connected
to a 15-amp circuit. The cooling unit uses approximately 11.8 amps during its “on”
cycle.
A number of variables, including the minimum set point, the temperature in the
ambient environment, the insulation of the cellar, and the thermal mass inside
the cellar, will affect the cooling unit’s runtime. It is normal for the cooling unit
to run up to 75 percent of the time in order to maintain proper conditions inside
the cellar.
Select a power receptacle (Front or Rear) and plug the provided power cord into
that receptacle. Plug the other end of the power cord into a dedicated 15 amp
circuit. A surge-protected circuit is recommended. Set the power selector
switch to energize the appropriate receptacle used (Front or Rear).
The power cord provided for the model 3200VSi and 4200VSi is approved for
indoor use only, while the power cord for model 3200VSx and 4200VSx may be
used both for indoor or outdoor applications.

II. Installation Instructions
TEST THE UNIT BEFORE INSTALLING IT
1. Remove the unit from the box. SAVE THE BOX AND PACKING
MATERIALS.
2. Plug in the power cord and let the unit run on a hard, flat surface.
3. Check to make sure that both fans (one in the front and one at the rear of
the cooling unit) are blowing.
4. Check that the cooling unit is discharging cold air from the front (it should
be approximately 10 - 12° F colder than the temperature on the digital
display)
Cut a hole in the wall that is 1/4 inch larger than the dimensions (W x
H) of the cooling unit, and create a frame to support the rear of the
cooling unit. The rear of the cooling unit should be supported by the wall
through which it is installed. Horizontal 2 x 4 inch braces should be installed
between the studs below and above the cooling unit. If the studs in the wall
must be cut to accommodate the width of the cooling unit, vertical braces also
should be installed on either side of the cooling unit.

Mount the unit in the upright position close to the ceiling inside the
cellar. As warm air rises to the top of the cellar, the cooling unit pulls the warm
air through the evaporator coil and removes the heat from the warm air. Once
cooled, the cold air is discharged from the front of the cooling unit and
circulates through the cellar.
Slide the unit through from the outside of the cellar. CAUTION: Two
people are required to move the cooling unit, which is very heavy. Do
not place the cooling unit on unprotected bottle racks.
Tilt the cooling unit slightly backwards. The rear of the cooling unit
should be slightly lower than the front of the cooling unit to facilitate the flow of
excess condensate to the drain line.
Use our adjustable mounting brackets to support and anchor the cooling
unit to the framing in the wall. Use the (16) #10x1-1/2” flat Phillips head wood
screws provided to anchor the screws into the studs and braces. The mounting
brackets can be used either inside or outside the cellar and can be used in three
different locations, as shown below.

Installation Notes:
1. The unit is shipped with (4) wall mounting brackets, a 90° drain elbow, and a 10’
length of ½ ” I.D. condensate drain line. The required hardware is shipped
loose with the unit.
a. Model 3200VSi / 4200VSi (indoor installations): Select the desired set of
mounting holes, location #1, #2, or #3 (shown above). The mounting
brackets can be used on either side of the wall.
b. Model 3200VSx / 4200VSx (outdoor installations): The rear cover uses hole
location #1. If this is also the desired location for the mounting brackets, first
make certain the rear cover is in place, and then install the mounting
brackets over the rear cover.
2. If the mounting brackets are used on the outside of the cellar in Location 1, a
shelf will be needed to support the weight of the cooling unit.
3. To attach the mounting brackets, attach the side and top brackets to the unit
using (8) #8x3/8” sheet metal screws. The bottom bracket only attaches to the
side brackets – there are no mounting holes for the bottom mounting bracket in
the case of the cooling unit. Secure the top and bottom brackets to the side
brackets with (4) ¼-20x5/8” bolts and lockwashers (included).
4. Attach insulated foam tape to the mounting brackets on the side that will face
the wall to create an insulated and airtight seal between the wall and the
brackets.
5. Once the cooling unit is installed, all cracks and gaps between the cooling
unit and the cellar should be sealed. A complete and proper seal must be made
between the cellar and the cooling unit to ensure that outside air does not enter the
cellar. Use sealant tape or caulking to seal the perimeter where the cooling unit
touches the cellar. Check the seal by having a helper stand in front of the cabinet
while you shine a flashlight around the cooling unit edges to discover any gaps in
sealant.
6. Thread the drain elbow tightly to the condensate overflow drain line. Thread
tape is not required. Run the overflow drain tube to a gravity drain, routing so
that the tube forms a water trap near the unit. Charge the tube trap with
water, then slide the ½ ”ID vinyl tubing over the hose barb.


15

As shown above, the drain line should drop, then rise (but stay below the
height of the fitting), and then drop again into a drain or bucket. Then, fill the
trap with water. The condensate trap will allow any excess moisture inside
the cooling unit to overcome the static pressure and flow out of the drain line.

Ducted Installations – Rear Duct Kit
1. Ductwork may be attached to the discharge only, or to both the discharge and
return adapters.
2. The unit is capable of operating with 100 equivalent feet of total ductwork, or
50 equivalent feet for both the discharge and return ducting, for the rear and
the front of the cooling unit. Elbows or bends will reduce this length. Use a
duct sizing program to determine the total equivalent feet of a specific duct
routing design, or consult the manufacturer for recommendations.
3. The “High” fan speed setting is recommended for long duct runs and as
ambient temperatures rise.
Ducted Installations – Front Duct Kit
1. Ductwork must be attached to BOTH the intake and exhaust openings,
connecting the cooling unit and the wine cellar.
2. The front duct kit includes two duct hoods. One hood is designed for intake
and will cover the lower portion of the cooling unit. This hood is completely


17
open on the rear. The second hood is designed for the exhaust and will cover
the top portion of the cooling unit. This hood is partially closed on the rear.
Both hoods are designed to attach to the cooling unit with 3/8” self-tapping
screws (included in the kit). SCREWS LONGER THAN 3/8” MAY NOT BE USED.
3. A bottle probe is included and is required for use with the front duct kit. The
bottle probe is designed to plug into the face of the cooling unit and terminate
inside the cellar. The bottle probe may be used to measure air or liquid
temperatures inside the cellar. If used to measure air temperatures, the
differential (HY) on the cooling unit should be set to “4”. If used to measure
liquid temperature, the differential should be set to “1”. To change the
differential on the cooling unit, please refer to our “Advanced Operation”
instructions in Section III.
4. The unit is capable of operating up to 50 equivalent feet for each duct. Elbows
or bends will reduce this length. Use a duct sizing program to determine the
total equivalent feet of a specific duct routing design, or consult the
manufacturer for recommendations.
5. The “High” fan speed setting is recommended for long duct runs and as
ambient temperatures rise.

 Summary
Keep in mind the following guidelines before purchasing a wine cooling unit
from CellarPro:
If the cellar it too large for the cooling unit, the cooling unit will be
unable to maintain proper, even temperatures throughout the cellar.
Without proper insulation and an airtight environment, the cooling unit
effectively will become a de-humidifier and potentially will produce
buckets of water.
The rear of the cooling unit must be installed in a space that is at least as large as
the wine cellar unless the rear intake and exhaust are ducted. Both the front and
the rear of the cooling unit require a minimum clearance of 8 inches.
Without access to cool air, either because of improper
ventilation or environments that are too hot, the cooling unit will be
unable to maintain proper temperatures inside the cellar.
Under these conditions, the unit’s internal components may become damaged, the
expected useful life of the wine cooling unit may be adversely affected, and the
product’s warranty may become null and void.

III. Operating Instructions
Overview
Test the cooling unit to make sure it is working properly before installing the
cooling unit (refer to the instructions at the beginning of the previous
chapter.)
CellarPro cooling units are designed to maintain optimal conditions for wine
storage and aging. These conditions include steady, cool temperatures, high
humidity, minimal vibration and light, and clean air.
The settings on your CellarPro cooling unit have been preset and optimized by
the factory. Before changing any settings below, we recommend waiting 14 days to
allow the cooling unit to “break in.”
The cooling unit is designed to cool the cellar gently without stripping moisture
out of the cellar environment. Therefore, it is not uncommon for the cooling unit
to run nonstop for up to a week initially, depending on the temperature inside the
cellar, the size of the cellar, and the temperature of the ambient environment.
Once the cellar has reached equilibrium, it is normal for the cooling unit to run
as much as 75 percent of the time.
CellarPro cooling units are designed to maintain optimal temperatures for storing
and aging fine wine. CellarPro cooling units are not designed to maintain
temperatures for serving wine, which tend to be much colder than storage
temperatures, especially serving temperatures for white and sparkling wines.
CellarPro cooling units must be used, stored, moved and/or shipped in the
upright position. Be careful when turning the unit on its side. The unit NEVER
should be turned upside down.
Temperature Control
CellarPro cooling units are designed to turn “on” when the air temperature passing
over the evaporator coils inside the cellar exceeds the Minimum Set Point plus
the Temperature Differential, and turn “off” when the temperature drops below
the Minimum Set Point. For example, if the Minimum Set Point is 58 ° F and the
Temperature Differential is 4 ° F, the cooling unit will turn on when the
temperature rises above 62 ° F inside the cellar, and it will turn off when the
temperature falls below 58 ° F. In this example, the average temperature inside the
cellar will be 60 ° F.


20

Basic Operation
The temperature inside the cellar can be increased or decreased by changing the
Minimum Set Point as described later in this chapter. If the cooling unit runs too
much, you can raise the Minimum Set Point to reduce the cycle “on” time. Most wine
collectors store their wine in the range of 55 - 60 ° F.
CellarPro cooling units are designed to maintain appropriate levels of humidity,
ranging from 50 to 70 percent, inside wine cellars. In order to increase or decrease
humidity inside the cellar, the Fon setting can be changed as described in the
“Advanced Operation” section later in this chapter.
