ank you for purchasing an N'FINITY cooling unit. We strive to provide the highest quality products and the best possible customer
service. If you have any questions about your N'FINITY unit, please call us at 1-800-648-6058.
is User’s Manual is intended to assist in the proper installation and maintenance of the N'FINITY cooling system. In order to ensure
the longevity of your cooling unit, the equipment should be installed properly and have a proper care and maintenance schedule.
Please read and review this manual carefully and keep it for future reference.
What Is the N'FINITY Cooling System?
e N'FINITY system 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. e system is fully self-contained and can be installed as a through-the-wall application. e stan-
dard through-the-wall units are temperature controlled via air sensor. e N'FINITY unit can be set at any temperature within the
acceptable wine-aging range of 50°F to 67°F. It is designed to cool 30°F cooler than the ambient temperature of the space to which it is
exhausting.
Page 4 WE 081313
e performance and life of your N'FINITY unit are contingent upon the steps you take in preparing the wine cellar.
Note: Improperly preparing your enclosure or incorrectly installing your N'FINITY unit may cause unit failure, leaking of condensa-
tion, and other negative side eects.
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. Wine Enthusiast 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 specic
needs that we do not address. If you have any questions regarding the building of your wine cellar, feel free to contact our storage con-
sultants at 800-377-3330.
Wall & Ceiling Framing
Build wine cellar walls using standard 2x4 or 2x6 construction methods and ceiling joists following the guidelines of local and state
codes in your area. As a general rule, the thicker the walls and the higher the insulation factor in your cellar, the better it will be at
maintaining a consistent temperature.
Insulation
Insulation is REQUIRED with the use of the N'FINITY product. Standard berglass or rigid foam insulation is normally used in cellar
construction or, in some cases, “blown-in” insulation is used. It is very important that all walls and ceilings are insulated to keep the
cellar temperature as consistent as possible during the summer and winter months. e R-value, or quality of insulation, is determined
by the rate at which heat passes through the insulation. e higher the R-value the more resistant the insulation is to conducting heat.
Using higher R-value insulation will lower your operating costs and unit run time. (R-13 minimum, R19 recommended, R30 for ceiling
and exterior walls)
Mounting the Unit
e unit should be mounted within 18“ of the top of the room in order to achieve sucient cooling. As the room cools down, the
warm air will rise to the ceiling. Mounting the N'FINITY 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 the
unit’s inability to draw warm air from the ceiling of the cellar to the unit itself.

Ventilation
e 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 up and adversely aect the unit’s ability to cool.
Vapor Barrier
Vapor Barrier is REQUIRED to prevent the intrusion of water vapor so that the cellar can be kept at the correct temperature and
humidity. 6 mm plastic sheeting (recommended) should be applied to the warm side of the cellar walls. e 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 cel-
lar. e 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 inltration of warm moist air. e 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.
Unobstructed Airow
Unobstructed airow to and from the unit is a critical factor in the unit’s overall performance. Make sure there is a minimum 3 . hori-
zontal clearance from the rear of the unit as well as a minimum 3 . clearance in front of the cooling unit. is will assure that the unit
can move the air around in an ecient manner. Avoid any attempt to camouage the unit by installing racking in front of the unit. is
will restrict the airow and lower the performance of the unit.
Ambient Temperature Factor
e cooling system has the ability to cool a maximum of 30°F below the ambient temperature of the room it is exhausting to. ere-
fore, you want to exhaust the unit in a room which will not exceed 85°F and preferably a consistent 75°F. Otherwise the unit will not
have the capacity to keep the wine at a desirable 55°F.
Door and Door Seal
At minimum an exterior grade (1 3/4”) door must be installed as a cellar door. It is very important that weather stripping is attached to
all 4 sides of the doorjamb. A bottom “sweep” or threshold is also required. e door must have a very good seal to keep the cool air in
and the warm air out. One of the most common problems with cooling units running continually is the door not sealing properly.
Sizing the Unit to the Room
e specication chart will provide information on the units room size cooling capacity. ere are circumstances in which a cellar design
may require a larger unit due to some existing design restrictions. In such a case, we recommend that the customer consider purchasing
a unit with a larger capacity to compensate for the design limitations. Issues such as glass doors, concrete, or brick walls and oors may
seem adequate but do not oer the insulation capacity required to maintain the optimum environment.

Electrical Needs
e N'FINITY System requires a dedicated 110-volt 20-amp circuit. e unit draws a large amount of amps at initial start up. By
designating a dedicated circuit breaker, you will guarantee the unit has enough power to run eectively. Contact an electrician for
assistance with the installation of this dedicated electrical circuit:
1. Match the electrical outlet to the plug provided on the N'FINITY unit.
2. Provide a dedicated circuit and wiring for the unit.
Electrical Outlet
Plug your N'FINITY unit into a surge protector or power conditioner. As with any sensitive electrical equipment, the N'FINITY
electrical equipment may be damaged by power surges and spikes. Power surges and spikes are not covered in the N'FINITY warranty.
WE RECOMMEND THAT YOU DO NOT USE A GROUND FAULT INTERRUPTER (GFI) WITH THIS PRODUCT.
Testing the Unit Prior to Installation
Carefully remove your N'FINITY unit from the box. Do not destroy your packaging material, as it provides the only safe
means of transporting the unit. Place the N'FINITY system on a tabletop to prepare it for installation and testing. Plug
system into a live electrical outlet and turn unit on. e system may take up to 10 to 15 minutes before operating correctly,
meaning all four fans are running. Cold air coming out on cellar side, hot air coming out on exhaust side. Once the
operation has been tested, turn the unit o, and unplug the unit from the electrical outlet.*
* Note: If the system does not seem to be fully functional aer 15 minutes, please refer to the Troubleshooting Guide on page 15.
Location of Supply and Return Grilles
Locate the supply and return grilles inside the cellar to create an airow pattern that maximizes air circulation in the room. Avoid short
circulation of the air.
DO NOT:
• Install through-the-wall return air grilles at oor level, as they will collect dust from the oor.
• Mount the unit lower than 18” from the top of the room.
• Locate the supply or return air grille where it is blocked by bottles, boxes or cases
Units weigh 75-85 pounds and are cumbersome for one person to carry. We recommend that you get someone else to help you during
the installation process. NEVER LAY UNIT ON ITS SIDE.
PRE-INSTALLATION
Page 7
PREPARING THE INSTALLATION LOCATION
Minimum Tools Needed
Locate the desired installation location (no lower 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 1 1/2” and no more than 18” from the ceiling.
Using a ruler or measuring tape, measure 16” down, 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 you have just made, and cut toward the
opposite stud so that you have a clean horizontal cut between the two studs. Be careful
not to cut into the studs themselves.
Now make the second horizontal cut from stud to stud on the line 16” 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 you have made both vertical cuts, you should have a rectangular
hole in the sheetrock. Now you have to make the same hole on the other side of the wall.
Since you already have one hole, this is an easy process. Using a nail, mark all four corners
of the rst hole by making nail holes through the sheetrock. en on the other side of the
wall, connect the holes with a pencil mark and cut.
Once the horizontal lines have been cut, make vertical cuts using the inside edge of the
studs as a guide. Once you have made both vertical cuts, you should have a rectangular
hole in the sheetrock. Now you have to make the same hole on the other side of the wall.
Since you already have one hole, this is an easy process. Using a nail, mark all four corners
of the rst hole by making nail holes through the sheetrock. en on the other side of the
wall, connect the holes with a pencil mark and cut.
Sheetrock alone cannot support the weight of a cooling system. erefore, it is necessary
to frame the hole that you have just cut with upper and lower supports. ese supports
also provide solid material for the mounting bracket screws.
Using two 2x4s at 14.5” in length and eight 6d nails, secure the upper and lower supports
to the right and le studs, just inside the sheetrock. Make sure that the internal height
remains at 16” so that the system will t snugly through the framed cut-out.

INSTALLING THE SYSTEM
rough-the-Wall
1. Slide the unit into the installation location from INSIDE the cellar,
make sure the controller side of the unit is inside of the cellar.
2. Slide the prepared single piece mounting bracket on the unit from
OUTSIDE the cellar.
3. On each side of the side of the unit you will notice 6 indents, these
mark 2 dierent installation depths. Select one of the 2 mounting
depths and attach the single piece mounting bracket to the unit with
the (6) supplied 1/2” self tapping screws. It is imperative to not use
self tapping screws longer than 1/2” in length.
4. Finally, secure the mounting bracket to the wall through the pre-drilled
holes with the (10) supplied #6 1 3/4" hex head screws. e screws should
penetrate the studs as well as the upper and lower supports to provide
adequate support for the unit.
5. Seal all cracks and gaps around the unit on the cellar side with an air-
tight sealant and caulking to prevent air leakage. e hole that the unit is
installed through is basically a break in the vapor barrier, an air tight seal
is imperative.
Note: If you use decorative moulding, it should be attached to the walls
and never to the cooling unit itself. e moulding itself should be remov-
able incase the unit needs servicing

Single Piece Mounting Bracket
e unit utilizes a single piece mounting bracket, this sturdy bracket frames the installation location
and secures the unit to the wall.
Applying Insulation Tape
Locate the (4) precut pieces of black foam tape included with the system, two larger pieces and two
smaller pieces. To apply, simply peel back the white-paper adhesive covering and place on the mount-
ing bracket. e large pieces are applied to the top and bottom while the smaller pieces are for the
sides. is foam creates a tight seal between the bracket and the wall.

DRAIN LINE
Condensation Drain Line Tube
e condensation drain line tube is used to remove excess condensation from the unit to a proper discharge location. It is important
that the drain line tube is properly connected and used to prevent leakage and other problems associated with excess condensation.
Failure to use the condensation drain line tube will void the warranty on the unit.
Drain Line Choices
Your unit is equipped with both a front and rear Drain Line Port. is allows you to choose if you would like to have excess condensate
drain back into the cellar for additional humidity. Simply remove the cap from the Drain Port you would like to utilize and thread the
supplied drain line and tting on. It is important that the drain line tube is properly connected and used to prevent leakage and other
problems associated with excess condensation. Please take note of the below illustrations that cover how the drain line needs to be
positioned.

EFFECTIVE JUNE 2012
Initial Start-Up:
When power is applied to the unit, the control will briey display all symbols, and the Compressor symbol will be displayed (if
unit is calling for cooling). ere may be a brief delay prior to the evaporator and condenser fans turning on.
Set Point:
e set point is set from the factory at 55°. It can be adjusted by the customer between 50° and 70° in one degree increments.
Cooling Operation:
Cooling is activated once the air sensor probe senses a temperature that is four degrees greater than the set point. e controller
then energizes the compressor relay which activates the compressor, evaporator fans and condenser fans. e unit provides cool-
ing until the air sensor probe senses the set point. At this point the compressor relay is de-energized which stops the compressor,
evaporator fans, and condenser fans.
Defrost:
Aer two hours of compressor operation the controller will activate defrost. e compressor relay will de-energize, stopping the
compressor, evaporator fans, and condenser fans. e compressor relay will remain de-energized for ve minutes, and then the
unit will return to normal operation. e set point and the dripping snowake will be displayed during defrost and until the unit
reaches set point aer a defrost cycle.
Display:
e Set point is displayed by default. e air sensing probe temperature can be accessed by pushing the set button and scrolling
through PB1 and set point parameters.
Safety Features:
Once the compressor relay is de-energized the controller must wait 5 minutes before re-energizing the relay. is prevents the
compressor from repeatedly turning o and on. If the unit is calling for cooling during this time, the compressor symbol will
blink indicating that cooling is needed but the control is waiting for the anti-short cycle delay.
In the event of a faulty air sensing probe, the compressor will cycle o for 10 minutes and on for 40 minutes. E1 will be displayed
on the screen.
Alarms:
e high temperature alarm (AH1) will be displayed if the room temperature reaches 10 degrees above the set point. e alarm
will reset once the temperature drops by 2 degrees. is alarm will only be active 10 hours aer the unit is turned on and will be
disabled for an hour aer an anti-frost cycle.
e low temperature alarm (AL1) will be displayed if the room temperature reaches 10 degrees below the set point. e alarm
will reset once the temperature increases by 2 degrees. is alarm will only be active 10 hours aer the unit is turned on. And
