While great effort has been made to provide accurate guidelines, BREEZAIRE cannot warrant its units to
properly cool a particular enclosure. Customers are cautioned that enclosure construction, unit location and
many other factors can affect the operation and performance of the unit. Therefore the suitability of the unit
for a specific enclosure or application must be determined by the customer and cannot be warranted by
BREEZAIRE.

INSTALLATION INSTRUCTIONS
FOR WKCE SERIES COOLING UNITS
The BREEZAIRE WKCE Series cooling units are designed to, when installed in a properly constructed
enclosure, provide a constant, selectable temperature between 48°F and 62°F while maintaining the relative
humidity to the proper 50% to 75%. BREEZAIRE cooling units are designed to lower the temperature, while
removing only excessive moisture. In a properly constructed enclosure this process can raise the relative
humidity. The unit does not add moisture to the enclosure. The unit does not include a heating system and
will not warm the enclosure. The WKCE Series is not intended to cool service cabinets, which are maintained
at lower temperatures and opened or entered frequently.
The Digital Electronic (Sentry III) thermostat has the following features:
Large, easy to read, green LED display.
Accurate, easy to adjust readable set points with continuous reading of enclosure temperature or
displaying of set point when changing enclosure temperatures.
Power outage protection, which delays unit start up after power outages.
Blocked airflow protection, which shuts down unit and protects wine in case of high temperatures
caused by condenser blockage.
Controls temperature by enclosure air sensors or optional bottle probe.
Please see the Sentry III Owners manual
The BREEZAIRE WKCE series, with the cold air discharge on the bottom of the cooling units were designed
and engineered for cabinets and credenzas. However if you have looked at the BREEZAIRE WKL series
cooling unit and you feel the WKCE series units will better serve your application consult your dealer for
assistance.
ENCLOSURE CONSTRUCTION GUIDELINES
To use the below SIZING GUIDE, the enclosure to be cooled must be built to the following minimum
specifications. If the enclosure cannot be built to these minimum specifications, consult your BREEZAIRE
dealer for assistance in choosing the correct unit. BREEZAIRE cooling units are not warranted to cool a
specific enclosure.
All walls, floors and ceilings should have a vapor barrier. This vapor barrier should be installed on the warm
side of the insulation. All interior walls and floors should be lined with a minimum of R-11 insulation and
exterior walls and ceiling insulation value should be a minimum of R-19. There should be no glass windows or
doors.
WKCE series are specifically designed and engineered to be installed in cabinets and credenzas. The
enclosures in which you install the cooling unit must be well insulated and air tight for the cooling unit to
perform properly.
All joints, door frames, electrical outlets or switches and any pipes or vents which go through the
enclosure should be sealed to prevent air and moisture leakage into the room. Concrete and brick are
not insulation or moisture barriers.
Doors into the enclosure should be of minimum size, insulated to R-11 and be tightly sealed with a high
quality weather stripping. Be sure to seal the bottom of the door and behind the door frame's molding.
Enclosure lighting should be of low wattage, with a timer to insure lights are not left on when the
enclosure is unoccupied. Recessed lighting should not be used, as they will allow outside air to enter the
enclosure.
If the ambient temperature surrounding the enclosure exceeds the enclosure's temperature by more
than 25°F the units cooling capacity will be reduced. No enclosure wall should receive direct sunlight or
strong wind.
Note: Glass doors and/or windows are not included in our calculations and should not be used in a wine
enclosure.

This is a mechanical piece of equipment, it will make some noise and produce heat on the warm side
exterior grille (Fig. 3). Remember, unit installation location is not only important inside the wine cellar,
but just as important is where the warm side exhaust air is being rejected.

INSTALLATION
Before installing the unit, inspect it again for any shipping damage. Test the unit by placing it in a room
where the temperature is above 65°F. Position the unit to allow cold air to flow from evaporator outlet. (See
Fig. 1) Plug the unit's electrical cord into a properly grounded electrical outlet of adequate capacity (see unit
specification for unit electrical requirements).
The control system has no "off" position; therefore it will begin to run within 5 minutes of being plugged in.
Allow it to run for a minimum of 15 minutes. There should be a flow of cool air from the lower evaporator
outlet side (see Fig. 1) and warm air should be flowing from the rear opening on the exterior grille side (see
Fig. 3). If there is no airflow or no change in temperature on either side, contact your dealer.
BREEZAIRE units should NOT be installed in a fire rated wall without consulting your local building
inspector and building codes.
The unit must be installed in the upright position and is not designed to have duct work on either the
warm air or cold air sides. Do not drill any holes into the cooling unit. It may damage the unit, promotes
rust, and will void the warranty. Do not install the unit so that its removal will be difficult or impossible. It
may be necessary to periodically remove the unit to clean the condenser coil.
The best location for the WKCE series cooling unit is six (6) inches from the ceiling, mounted on a shelf
(see above unit specifications for weight of unit) and with no obstruction for the evaporator cold air outlet
airflow (minimum 12 inches) and a minimum of three (3) feet for the warm air discharge from the exterior
grille. (see Fig. 1, 2 and 3) It is preferred that the unit be mounted as close to equal distance from each
end of the wall as possible.
The area into which the unit exhausts must be well ventilated. If not, the unit will be unable to reject the
excessive moisture and heat, resulting in unsatisfactory performance. Inappropriate locations for the
WKCE 05/11 PG 3

warm air exhaust includes unventilated small rooms, closets, bathrooms, hot garages, unventilated crawl
spaces, attics and humid basements.
Make sure that the warm air exterior grille can be properly attached to the unit (see Fig. 3).
Make a hole through the wall as illustrated in Fig. 2. Construct a shelf as shown in Fig. 3. This shelf
must be capable of supporting the weight indicated in the specifications. NOTE: Insulation placed
between the unit and the shelf will reduce noise and help reduce condensate from forming on the
underside of the unit.
If your installation cannot be performed in accordance with these instructions contact your
dealer.
Place the unit through the opening with the exhaust side flush to the outside wall. Attach the warm side
exterior grille (Fig. 1&3) to unit and wall with screws supplied. Please remember that in all cases the exterior
grille must be directly attached to the warm side of the unit. Do not leave an air gap between the unit's
surface and the exterior grille. The unit will not work properly without this grille. The warm side exterior
grille has only a white primer coat. If the grille is installed on an outside wall it should be coated with an
appropriate paint to prevent rust.
OPERATION
On initial start-up the cooling unit will reduce the temperature of the enclosure slowly. The unit may run
constantly or cycle off for short periods. The time required to reach the desired temperature will vary,
depending on the enclosure's construction and contents.
The thermostat is factory set to 55o Fahrenheit. Unless the temperature falls below that desired, do not
change the thermostat setting for at least 3 days.
During normal operation of the Sentry III thermostat the LED readout will display the temperature of the air
entering the intake of the cooling unit. If the optional bottle probe is installed the intake air sensor will be
disconnected and the temperature of the probe will be displayed. The temperature being displayed is also the
temperature used by the control system to turn the cooling unit on and off.
After initial cool down, the "on-off" cycle should be relatively constant. The percentage of "off " time will
depend on enclosure's construction, placement of unit, contents, and surrounding outside temperatures. If it
is necessary to adjust the temperature of the enclosure; adjust the thermostat to a colder temperature while
the unit is running and to a warmer temperature while the unit is off. The set point may be set no lower than
48°F or higher than 62°F. NOTE: If the enclosure is not cooling to the current set point, lowering the set point
temperature further will not help. (See ENCLOSURE PROBLEMS section)
The Sentry III set point (desired enclosure temperature) may be changed by pressing and holding the "SET"
button while pressing the "COOLER" or "WARMER" button. When the "SET" button is pressed the readout
will automatically change and display the current set point temperature

Should the operation of the cooling unit be interrupted by a power outage or by raising the set point
temperature while the unit is running the Sentry III internal delay will be activated and the unit will not restart
for two (2) to three (3) minutes. NOTE: This delay may also occur on initial power-up.
MAINTENANCE
The BREEZAIRE cooling unit requires very little maintenance. To keep the system operating at its top
performance, at least once every three months the condenser coil should be inspected and vacuumed to
prevent air blockage. Remove the large warm air exhaust grille located outside the enclosure where the warm
air is discharged. Use a vacuum with a brush attachment to remove the lint or dirt that may reside between
the aluminum fins. If the condenser coil becomes blocked the unit will over heat causing a loss in
cooling efficiency and will result in a failure of the unit not covered under warranty.
ENCLOSURE PROBLEMS
BREEZAIRE is extremely proud of the quality and reliability of its products. Experience has shown that of
the small number of problems encountered, the large majority are due to improper unit selection or enclosure
construction. Should the cooling system be suspected of malfunctioning, check the temperature of the air
being exhausted from the warm air exterior grille. If it is warm, the unit is working. A further check may be
made by comparing the temperature entering the front grille on the cold side (Evaporator Intake) with that
leaving from the bottom left side (Cold Air Outlet)(see Fig.1). If the air leaving the unit is 6°F or more colder
than the temperature entering, the unit is working properly. In some cases, improper placement or installation
may cause the unit's performance to be compromised.
In situations where the ambient relative humidity is very low, the desired enclosure relative humidity may not
be achieved without adding moisture. To add moisture to the enclosure only use slow, natural evaporation
from a small porous water container. Do not use a humidifier.
In some cases, improper placement or installation may cause the unit's performance to be degraded. The
warm air exterior side of the unit must have a constant supply of fresh air. If the unit is exhausted into a
confined area with poor ventilation, it will not be able to reject the heat and moisture it is removing from the
enclosure and a malfunctioning unit will be suspected. If an obstruction to the flow of fresh air into or from the
cooling unit (see Fig. 3) is stopped or restricted for any reason the unit could heat rather than cool the
enclosure.
NOTE: Should this condition develop when using the Sentry III, the unit will turn off when the enclosure
temperature rises to approximately 75°F, the unit will not restart until the enclosure temperature is lowered to
approximately 65°F or the unit is disconnected and then re-connected to the power supply. This feature is
disabled for approximately 45 minutes after the unit is connected or re-connected to a power supply.
Proper sealing of the enclosure through the use of a vapor barrier and weather stripping cannot be over
emphasized. The unit will not be able to maintain the proper conditions if fresh, moisture-laden air is
constantly being introduced into an improperly sealed enclosure. Symptoms of this condition are; unit runs all
the time with only a slight reduction in enclosure temperature and/or water overflows from the unit. One way
of discovering gross air leaks is to stand inside the enclosure with the lights off, allow your eyes to adapt to the
dark and look for light showing through cracks in the walls or around the door. Also close the door on a piece
of paper, if you can pull the paper through the door, that means air and moisture are also entering into your
wine cellar. Because of the temperature difference between the inside and outside, very small cracks can
allow large amounts of outside air into the enclosure. Please be aware that moisture will pass through solid
concrete, brick, paint, paper and wood.
