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 WK SERIES COOLING UNITS

The BREEZAIRE WK Series cooling units are designed to, when installed in a properly constructed enclosure, provide a
constant, selectable temperature between approximately 48°F and 63°F while reducing the excess 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 WK Series is not intended
to cool service cabinets, which are maintained at lower temperatures and opened or entered frequently.

The WK Model has a mechanical thermostat and its adjustments requires a 1/4" straight type screwdriver. Turning the
adjusting screw clockwise lowers the set point, counter-clockwise raises it.

The WKL Model has a digital electronic (Sentry III) thermostat that adds additional safety and convenience features:

F Large, easy to read, green LED display.
F Accurate, easy to adjust (no tools needed), readable set points with continuous reading of enclosure temperature or

displaying of set point when changing enclosure temperatures.

F Power outage protection, which delays unit start up after power outages.
F Blocked airflow protection, which shuts down unit and protects wine in case of high temperatures caused by

condenser blockage.

F Controls temperature by enclosure air sensors or optional bottle probe.

ENCLOSURE CONSTRUCTION

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 doors and/or windows.

F 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.

F 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.

F 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.

F The ambient temperature surrounding the enclosure should not exceed the desired cellar's temperature by more than

25°F. No enclosure wall should receive direct sunlight or strong wind.

F This is a mechanical piece of equipment , it will make noise and produce heat on the warm side exterior condenser

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.

F Note: Glass doors and/or windows are not included in our calculations and should not be used in a wine enclosure.

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 is factory set to approximately 55°Fahrenheit. Unless the temperature falls below that which is desired, do

not change the thermostat setting for at least 3 days.
During normal operation the (optional) Sentry III thermostat's 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 can be adjusted no lower than 48°F or higher than 63°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 (WK Model) only requires a small clockwise turn of screw to lower the enclosure
temperature. This screw is located on the front of unit. (See Fig. 1) (CAUTION) If the operation of the unit is stopped,

either by unplugging it or by turning the thermostat, do not restart it for at lease 10 minutes.

The Sentry III set point (WKL Model), desired enclosure temperature, may be changed by pressing and holding the "SET"
button while momentarily 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's internal delay will be activated and the unit will not restart for approximately three (3)
minutes. NOTE: This delay may also occur on initial power-up.

MAINTENANCE

The BREEZAIRE cooling unit requires very little maintenance. To maintain optimal performance, the condenser coil
should be inspected and cleaned every 3 months. Remove the exhaust condenser grille located outside the enclosure and
use a vacuum (with brush attachment) to remove dirt and lint from the fins of the condenser coil.

If the condenser coil becomes blocked preventing proper air flow the unit will over heat causing a loss in cooling
efficiency and will result in a failure of the unit not covered under warranty.

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 upper part of
the warm air exhaust condenser grille. If it is warm, the unit is working. A further check may be made by comparing the air
temperature entering the lower grille on the cold side (Evaporator side) with that leaving the upper cold side grille. (see Fig.

1) If the air leaving the unit is 6°F or more degrees 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.

ENCLOSURE PROBLEMS

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 evaporator side upper grille (see Fig. 1) and warm air
should be flowing from the upper opening on the warm air exhaust (condenser) grille (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 If your installation cannot be performed in accordance with these instructions contact your dealer.
F The unit must be installed in the upright position and is not designed to have ductwork on either the warm air or cold

air sides. Do not drill any holes in 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 Select a place to mount the unit where the airflow from the warm air exhaust is unobstructed for a minimum of 3 feet.

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.

F An inappropriate location for the warm air exhaust includes unventilated laundry rooms, closets, bathrooms, garages,

crawl spaces, attics and humid basements.

F Additionally, cold air flowing from the upper

cold side grille must remain unobstructed for 3
feet. It is preferred that the unit be mounted
near the ceiling and as close to equal distance
from each end of the wall as possible. If
necessary, the WK3000, WK4000, WK6000,
and WK8000 may be mounted near the floor if
the upper grille is interchanged with the blank

knife.

F Make sure that the warm air exhaust condenser grille can be properly attached to the unit (see Fig. 3).
F Make a hole through the wall as illustrated in Fig. 2. The dimensions of the hole should be approximately 1/4 inch

larger than the width and height given in the specifications. If the 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.

F Cut a hole in the shelve that corresponds to the Pull down drain tube's location on the underside of the unit. Refer to

section "ENCLOSURE PROBLEMS".

F Place the unit through the opening with the warm air exhaust side, flush to the outside of the wall (see Fig. 3). Attach

the warm air exhaust condenser grille to the unit and to the wall with screws supplied with grille. Note: the unit may
be installed with the cold side flush to the inside wall, however, two provisions must be made. First, insure the warm
air exhaust grille will be installed. Second, insulate and vapor barrier the framed opening to prevent moisture in the
wall from condensing on the cold surface of the cooling unit. Please remember that in all cases the warm air exhaust
condenser 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 warm air exhaust condenser grille. The unit will not work properly without this grille. The
exhaust condenser grille has only a white primer coat. If the exhaust condenser grille is installed on an outside wall it
should be coated with an appropriate paint.

F Seal the opening around the unit with high quality weather stripping and cover with an appropriate molding.

Attach the molding to the wall, not the unit.

F Plug the unit's electrical cord into a properly grounded electrical outlet of adequate capacity (see unit specification for

unit electrical requirements) (CAUTION) If the operation of the unit is stopped, either by unplugging it or by

turning the thermostat, do not restart it for at lease 10 minutes.

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.

Improper placement or installation may cause the unit's performance to be degraded. The warm air exhaust side
(Condenser 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 or duct work, 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 to allow initial cooling of enclosure.

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 seal, it means air and moisture are
also entering into your enclosure. 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. A newly constructed room may contain fresh wood, paint, concrete and other building
materials containing large amounts of moisture. This condition can cause symptoms similar to a poorly sealed enclosure,
but will gradually go away.

NON EXTENDED DRAIN

(TUBE LOCATION)

EXCESS CONDENSATE DRAIN TUBE: Your unit is equipped with a Pull-down Drain tube to prevent condensate
overflow. To temporarily drain excess amounts of condensate engage the drain tube and provide a receptacle or drain to
receive the excess condensate.

EXTENDING THE DRAIN TUBE: To extend and open the drain, use a pair of small pliers to grab the red plastic plug
and vinyl tubing. Pull the plug and tubing down approximately 6 inches until it snaps into the locked position and the "Grey
Fitting" is visible through the drain hole (see Fig. 4). Remove the bottom red plug. Now the cooling unit will drain any
condensate that is standing above 1/4 inch deep in the base pan.

CLOSING THE DRAIN TUBE: To close the drain tube, simply replace the "Red stopper" and push the vinyl tubing back
up into the bottom of the cooling unit. This action extends the top of the tube above the water line preventing it from
draining. CAUTION: Do not push the entire length of tubing back up into the drain hole.

INSTALLING A DRAIN LINE: To extend the drain tube into a basement drain or container, acquire a length of vinyl
tubing with an inside diameter of 1/2 inch from a local hardware store. Slip this larger piece of tubing over the Pull-down
drain tube. CAUTION: Always have the extended drain line running "down hill". This is a gravity flow system. If a
horizontal run is encountered, an air vent or condensate pump may be required to maintain drainage.

Do not drill or tap the drain hole. Doing so will result in rusting of the metal base and void the unit's warranty.
