Using the Manual
This manual is intended to assist in the proper installation and maintenance of the CellarCool cooling unit. In order to ensure the
longevity of your cooling unit, the equipment should be installed correctly and have a proper care and maintenance schedule.
Please read and review this manual carefully and keep it for future reference.
What is the CellarCool Cooling Unit?
The CellarCool cooling unit is a specialized refrigeration unit designed for one purpose only: to maintain the optimal
temperature and humidity levels conducive to the proper storage and aging of ne wines. It is a self-contained cooling unit
designed to be used as a forced-air, through-the-wall unit.
How Does the CellarCool Ultimate Series Work?
The CellarCool unit is especially designed to maintain optimal conditions for wine storage and aging. The unit is fully self-
contained and can be installed through most walls. The unit is also capable of a more exible ducted application, which allows
the unit to be placed in an indoor remote site, resulting in a quiet airow.
Temperature Setting
The CellarCool cooling unit can be set at any temperature within the acceptable wine-aging range of 55–70°F. It is designed
to create a dierential of up to 55°F between the cellar and the ambient temperature (as long as the space to which the unit is
exhausting does not exceed 110˚F).

UNIT SPECIFICATIONS
FAN SPEED
Fan speed selection is determined by the amount of heat that needs to be removed from the cellar and the type of installation
(through-the-wall or fully ducted). Fan speed selection is based on the cellar size, insulation factor, door seal, and desired wine
temperature. When initially installing the unit, set the fan speed to the High setting to quickly chill the wine cellar. Once the
wine cellar reaches the desired temperature, a lower fan speed may be selected. In the event that the outdoor temperature rises
above 90°F, (when exhausting to the outdoors) a higher fan speed may be required.
* Sizing the Unit to the Room
The specication chart will provide information on the unit's cooling capacity. There are circumstances in which a cellar design may
require a larger unit due to preexisting design restrictions. Certain building materials such as glass, stone, or concrete may seem
adequate but do not oer the insulation capacity required to maintain the optimum temperature for storing wine. We recommend
purchasing a unit with a larger capacity to compensate for these design limitations. Undersized cooling units can lead to premature
failure and/or prevent the system from reaching the desired set temperature. As a result, they are not covered under warranty.
Fully ducted units should be set to the HIGHEST fan
speed selection for maximum performance.

The performance and life of your system is contingent upon the steps you take in preparing the wine cellar. Improp-
erly preparing your enclosure or incorrectly installing your unit may cause unit failure, leaking of condensation, and
other negative side eects.
It is highly recommended that you obtain the assistance of a wine storage professional.
Wine storage professionals work with licensed contractors, refrigeration technicians, and racking companies to build
well-insulated, beautiful, and protective wine cellars. CellarCool has put together some useful tips to assist in the
installation process. Our recommendations are meant to act as a guide in the process of building a proper enclosure.
Your intended location may have specic needs which we do not address.
Wall & Ceiling Framing
Build wine cellar walls using standard 2x4 or 2x6 boards and ceiling joists without violating local or state codes in
your area. As a general rule, the thicker the walls and the higher the insulation value, the more consistent your cellar
temperature will be.
Insulation
Insulation is REQUIRED in order to properly use CellarCool products. It is vital that all walls and ceilings be insulated
to keep the cellar temperature as consistent as possible during the summer and winter months. Standard berglass
or rigid foam insulation is normally used in cellar construction; in some cases,“blown-in”insulation is used. The
R-value, or quality of insulation, is determined by the rate at which heat passes through the insulation. The higher
the R-value, the more resistant the insulation is to conducting heat, and the more consistent your wine cellar’s
temperature will be. Using higher R-values in insulation will lower your operating costs and CellarCool unit run time.
(R-13 is the recommended minimum; R-19 is preferred for interior cellar walls, and R-30 for ceilings and exterior walls.)
Vapor Barrier
Water vapor creates its own pressure, separate from the ambient air pressure, and will intrude into colder/drier
areas. A vapor barrier is REQUIRED in order to prevent the intrusion of water vapor and maintain the correct cellar
temperature and humidity. It is recommended that 6-millimeter plastic sheeting be applied to the warm side of the
cellar walls. The vapor barrier must also be applied to the outside walls and ceiling. If it is impossible to reach the
outside, then the plastic must be applied from within the cellar. The most common method is to wrap the entire
interior, leaving the plastic loose in the stud cavity so the insulation can be placed between each stud. All of the walls
and ceiling must be wrapped in plastic for a complete vapor barrier.
In areas of high humidity, such as Southern and Gulf States, the vapor barrier will prevent inltration of warm moist
air. The moist air can cause mold to form, and standing water in drain pans promote microbial and fungal growth that
cause unpleasant odors and indoor air quality problems. If mold is found, remove it immediately and sanitize that
portion of the unit.
Note: High humidity signicantly increases the heat load on the cooling system.
Any break in the vapor barriers (cut, nail hole, over-lapping, etc.) will cause a moisture leak and must be sealed. The
electric conduit is a “duct”for vapor to travel in. The conduit should be caulked and sealed on the warm air end.

Mounting the Unit
The unit must be mounted within 18 inches of the ceiling in order to achieve sucient cooling. As the room cools down, the
warm air will rise to the ceiling. Mounting the unit high in the room will create a consistently cool environment by capturing the
warm air and replacing it with cool air. Mounting the unit low in the room will result in a temperature variation in the room due
to (a) the unit’s inability to draw warm air down from the ceiling and (b) cold air settling to the oor.
Door and Door Seal
An exterior-grade (1¾”) door must be installed as a cellar door.
It is very important that weather stripping be attached to all
four sides of the doorjamb. A bottom “sweep” or threshold is
also required. The door must have a very good seal to keep
the cool cellar air from escaping out of the cellar. If the cellar
door does not seal properly, the unit will run continuously.
In cases where glass doors are used and the room size is
close to the recommended unit size, the next larger size
WhisperKOOL should be used. This will compensate for the
insulation loss due to the lower insulation rating of glass.
Unobstructed Airow
Unobstructed airow to and from the unit is critical for the unit’s overall performance and lifespan. Make sure there is a
minimum of three (3) feet of horizontal clearance in every direction around the unit (ve feet is ideal). The air blown by the fans
needs to circulate and either dissipate or absorb heat from the space. The system will operate more eciently with a greater
amount of air to exchange.
NOTE: Do not attempt to mount the unit in a wall recess or attempt to camouage or cover the unit with any sort of aftermarket
grille, accessory, etc. This can restrict airow, prevent the unit from working properly, and void the warranty. Please feel free to
call CellarCool Customer Service with any questions or concerns regarding installation requirements.

Ambient Temperature Factor
The cooling unit has the ability to cool a wine cellar eciently to 55°F as long as the ambient temperature of the area that it is
exhausting to does not exceed 110°F. Therefore, you want to exhaust the unit in a room which will not exceed 110°F. Without
proper heat dissipation the unit will not have the capacity to keep the wine at a desirable 55°F.
Ventilation
The necessity of dissipating heat away from the unit is critical to the unit’s performance and cannot be overstated. As the unit
operates and cools, a greater amount of heat is generated on the exhaust side of the unit. Adequate ventilation is required in
order to dissipate heat away from the unit. If ventilation is inadequate, the exhaust will heat the area or room and adversely
aect the unit’s ability to cool. In some cases, it may be advisable to install a vent fan to dissipate heat from within the exhaust
area. However, you must have a fresh air inlet as well. If your unit requires ducting, please contact CellarCool to obtain a specially
designed ducting plenum for the unit.
Using any other ducting system will void the warranty.
Note: If you are unsure whether you have adequate ventilation in your install location, please
contact us to assess your specic installation at supp[email protected] or 1-855-235-5271.
WARNING! Allowing your unit to operate in high ambient temperatures for extended
periods of time will greatly decrease the life of your unit and void your warranty.

PREPARING THE UNIT FOR INSTALLATION
The CellarCool unit requires a dedicated 115V, 20-amp circuit. The unit draws a large amount of amps during its initial
startup. By designating a dedicated circuit breaker, you will guarantee the unit has enough power to run eectively. Contact an
electrician for assistance with the installation of this dedicated electrical circuit.
The unit must sit upright for 24 hours prior to installation. To prepare the unit for installation:
• Remove unit from box.
• Match the electrical outlet to the plug provided on the CellarCool unit.
• Provide a dedicated circuit and wiring for the unit (see above).
• Provide a weatherproof plug for units connected outside.
Power surges and spikes can damage sensitive electrical equipment. CellarCool recommends plugging the unit into a surge
protector or power conditioner in order to protect your system. As outlined in our terms and conditions, power surges and spikes
are not covered under warranty.
Do not use a GFI (ground fault interrupter) with this product.
The unit is equipped with two power inlets. One is located on the right side of the unit (inside of the cellar), and the other is
located on the rear of the unit (outside of the cellar). Use the selector switch located on the right side of the unit to select which
power inlet you would like to use. If you would like to plug the unit into a socket outside of the cellar, set the selector switch to
rear. If you would like to plug the unit into a socket inside of the cellar, set the selector switch to the front position. When placed
in either position, power can only enter the unit utilizing the power inlet you’ve selected.
In case the unit should lose power, check the home/main circuit breaker. If the unit does not respond properly, refer to the
Troubleshooting Guide.

Hammer SawScrewdriver
Level
Locate the desired installation location (no more than 18 inches from the ceiling).
Using a stud nder, locate the studs on either side of the center point and mark them
with vertical lines.
Using a level and a pencil, mark a horizontal line on the wall between the two studs,
no less than 1½ inches and no more than 18 inches from the ceiling.
Using a ruler or measuring tape, measure 16 inches down (3300-R and 4400-R) or
22.25 inches down (8800-R), and mark another horizontal line parallel to the rst one.
Using a saw, cut along the uppermost horizontal line until your saw reaches the stud.
Turn the saw around, inserting it into the cut that has just been made, and cut toward
the opposite stud so that there is a clean horizontal cut between the two studs. Be
careful not to cut into the studs themselves.
Make the second horizontal cut from stud to stud on the line 16 inches below the rst
cut.
Once the horizontal lines have been cut, make vertical cuts using the inside edge
of the studs as a guide. Once both vertical cuts have been made, there should be
rectangular hole in the sheetrock. Make the same hole on the other side of the wall.
Using a nail, mark all four corners of the rst hole by making nail holes through the
sheetrock. Connect the holes with a pencil mark and cut on the other side of the wall.
Sheetrock alone cannot support the weight of a 96-lb cooling unit. Therefore, it is
necessary to frame the hole that has just been cut with upper and lower supports.
These supports also provide solid material for the mounting bracket screws.
Using two 2x4s (14.5 inches in length) and eight 6d nails, secure the upper and lower
supports to the right and left studs, just inside the sheetrock. Make sure that the
internal height remains at 16 inches (3300-R and 4400-R) or 22.25 inches (8800-R) so
that the CellarCool unit will t snugly through the framed cut-out.
PREPARING THE INSTALLATION LOCATION
Minimum Tools Needed:

www.cellarcool.com | Page 13
Ultimate Series
PREPARING THE UNIT FOR INSTALLATION
A sturdy single-piece mounting bracket is used to frame the
installation location and secures the unit to the wall studs. The
bracket has been designed to hold the unit at a two-degree (2°)
angle. This helps project air into the space and aids in condensation
drainage.
Applying Insulation Tape
Locate the six-foot piece of black foam tape included with the unit.
Align one end of the foam tape with the upper left corner of the
rear side of the mounting bracket. Stretch the tape across the rear
of the bracket and cut the tape at the opposite edge. Peel o the
white paper backing and attach the cut piece of foam tape to the
top rear side of the mounting bracket. Follow the same procedure to
place a piece of tape on the bottom edge of the mounting bracket.
Place the remaining piece of foam tape on one side of the mounting
bracket (spanning the distance between the pieces of tape on the
top and bottom edges of the mounting bracket), then cut, remove
paper backing, and secure. Do the same on the opposite side of the
bracket. Discard any excess. The foam tape will create a tight seal
between the bracket and the wall.
If you are installing through an exterior wall, please review the
next page for specic instructions on exterior grill installation.
Mounting Bracket Installation
Select your desired bracket mounting location (see diagram below). This location determines the depth of the installation. For
example, position #1 keeps most of the unit out of the cellar while position #4 sets the back of the unit near ush with the
exterior wall. Slide bracket onto unit. Ensure that the TOP label on the bracket and the unit mounting anges are towards the
back. Use the four supplied ½” pan-head screws to fasten the bracket to the unit. It is imperative that you use screws no longer
than ½” in length.

OPTIONAL EXTERIOR GRILLE
The exterior grille is required on all installations where the exhaust side of the unit is exposed to the outdoors (i.e., rain and other
adverse weather conditions).
Non-Flush Installation
Install the unit according to the standard through-the-wall procedure. After the unit is installed, place the exterior grille over the
exhaust side lter grille and line up the screw holes on the top, bottom, and sides. Use the supplied ½" pan-head screws to fasten
the grille to the unit.
Flush Installation
This installation is slightly dierent because you are utilizing the same holes for both the mounting bracket and exterior grille.
1. Slide the mounting bracket onto the unit followed by the exterior grille, bring the two pieces together by sliding the exterior
grille over the mounting bracket side anges.
2. Align the two top screw holes of the exterior grill with the top screw locations on the unit, use the supplied ½" pan-head
screws to fasten the grille.
3. Repeat Step 2 on the bottom of the unit.
4. Use the supplied ½" pan-head screws to fasten the grille and bracket to the unit ensuring the bracket stays perpendicular/
square.
5. Continue through-the-wall installation.
You are required to use the ½” pan-head screws provided. Do not drill holes into unit.

PRE-INSTALLATION WIRING
1. Remove the face plate by removing the four screws at each corner.
2. Insert a standard 18-5 thermostat wire through the small hole on the left side of the face plate as shown below, left.
Connect it to the wire behind the panel inside the unit (circled in red below, right). Connect the wires according to color:
green to green, blue to blue, yellow to yellow, and red to red. (The white wire will not be used.)
3. Replace the face plate and tighten the four screws in each corner.
4. Install the supplied black strain relief around the 18-5 thermostat wire where it enters the unit.
5. Continue through-the-wall installation.
NOTE: To ensure correct system operation, the 24V thermostat must be placed
inside the wine cellar, preferably in a central location away from any airow.

ULT 061219
Page 16 | 1-855-235-5271
INSTALLING THE UNIT
Slide the unit from the outside wall into your wine cellar with the outer ange ush with the wall. Secure the ange to the wall us-
ing the pre-drilled holes. The 1¾" screws should penetrate the studs as well as the upper and lower supports to provide adequate
support for the CellarCool unit (see illustration). Seal all cracks and gaps around the CellarCool Ultimate unit with an air-tight seal-
ant or caulking to prevent air leakage. Connect the other end of the 18-5 thermostat wire that was routed into the unit to the 24V
thermostat. At the thermostat terminal block, connect the wires according to color: yellow to Y, blue to C, green to G, and red to R.
Note: If you use decorative moulding, it should be attached to the walls and never to the
cooling unit itself. The moulding itself should be removable in case the unit needs servicing.

DUCTING OVERVIEW
Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only insulated ductwork to minimize
cooling losses, prevent sweating, and reduce noise. Use ductwork on the condenser section to redirect or absorb sound, bring in
outside air to the unit inlet, and/or exhaust the hot air.
Note: Do not exceed a total of 25 feet for each length of ductwork run and a combined total of 50 feet for both the supply
and return lengths.
Avoid crimping the exible ducts. This reduces airow, causing the unit to operate improperly. Be sure all ductwork and outer
surfaces in contact with the airow are insulated and have a vapor barrier on the outside. Uninsulated supply and return ducts
may cause bare, exposed metal surfaces to sweat, further degrading the insulation and equipment cooling capacity.
Do not allow sharp turns to squeeze or decrease the
inside diameter of the exible ducting.
General duct recommendations:
• Provide support for the exible duct to prevent sags and bends.
• 3300-R and 4400-R duct size: 8” supply and return
• 8800-R duct size: 8” supply and 10” return
• Stretch out the duct to make a smoother interior which reduces air resistance.
• Maximum duct length is 25 feet.
• For 90° bends, use a 90° adjustable elbow.
• No more than two 90° bends on each duct. Sweep 90° bends are recommended rather than sharp 90° bends.
• Generously apply duct sealant to all metal seams to ll in gaps that can leak air. Allow sealant to dry until rm to the touch
before applying berglass insulation.
• Do not squeeze or reduce the inside diameter of the ducts, as this will reduce airow.
• Use short and straight ductwork where possible.
• Check that all fan blades move freely.
• Keep air paths free of loose foreign objects and debris.
• To provide adequate airow the fan speed must be set to high when the unit is ducted.
• Locate the supply and return grilles inside the cellar to create an airow pattern that maximizes air circulation in the room.
Avoid short circulation of the air.
• If the unit is installed through the wall, it must be mounted no more than 18 inches from the wine cellar ceiling. If the unit is
ducted, the cold air supply duct must be installed no more than 18 inches from the wine cellar ceiling.
DO NOT:
• Install through-the-wall return air grilles at oor level where they will collect dust from the oor.
• Locate the supply or return air grille where it is blocked by bottles, boxes, or cases.
