While great effort has been m ade to provide accurate guidelines, BREEZAIRE cannot warrant its units to properly cool a particular enclosure. Custom ers are cautioned that
enclosure construction, unit location and m any other factors can affect the operation and perform ance of the unit. Therefore the suitability of the unit for a specific enclosure or
application m ust be determ ined by the custom er and cannot be warranted by BREEZAIRE.

CONVERTED CLOSETS APPLICATIONS
The BREEZAIRE WKC series cooling units were designed and engineered for cabinets and credenzas. However if you
have looked at the BREEZAIRE WK series cooling unit and you feel the WKC series units will better serve your
application you must follow theses specifications:
F
This is a mechanical piece of equipment, it will make 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 thermostat 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.
F
BREEZAIRE units should NOT be installed in a fire rated wall without consulting your local building inspector
and building codes.
F
F
If your installation cannot be performed in accordance with these instructions contact your dealer.
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.
F
The best location for the WKC 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 is mounted as close
to equal distance from each end of the wall as
possible.
F
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 warm air exhaust includes unventilated laundry rooms, closet, bathrooms,
garages, 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. This unit is to be installed above floor level, 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 additional noise and help reduce condensate
from forming on the underside of the unit.
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.
o
The thermostat is factory set to approximately 55 Fahrenheit. Unless the temperature falls below that desired, do not
change the thermostat setting for at least 3 days.
During normal operation of the (optional) 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)

Adjustment of mechanical thermostat only requires 1/8 clockwise turn of screw to lower enclosure temperature. Screw
is located on front of unit. (See Fig. 1)
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
o
exterior side of the unit must have a constant supply of fresh air, less than 85 F. 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.
