--INSTALLATION INSTRUCTIONS--

Thank you for choosing a BREEZAIRE cooling unit. We believe our products are

the best on the market and will provide many years of trouble free service.

Please take a few minutes and read this entire instruction before beginning the installation.

Before removing the cooling unit from the box, please inspect for damage which might have been

incurred during shipping. If damage is found, notify the Freight Company immediately.

BREEZAIRE is not responsible for any damages incurred during shipping.

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 WKS 4000 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 48°F and 62°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 WKS Series is not intended to cool service cabinets, which are maintained at lower temperatures
and opened or entered frequently.

The WKS Series cooling unit, is shipped as components, not a working cooling system. Only after a qualified
refrigeration installer has properly connected these components, pressured tested, evacuated, charged with
refrigerant and tested their installation, can the unit be considered a cooling system. Proper installation is critical
to the performance, reliability and longevity of the system. For this reason, BREEZAIRE can only warrant the
quality of the WKS components. The installation and proper operation must be warranted by the installer.
Before installation is to begin, the purchaser and installer should carefully read the enclosed Limited Warranty.

ENCLOSURE CONSTRUCTION

To use the below SIZING GUIDE, the enclosure to be cooled must be built to the following minimum
specifications. If the enclosure is not built to these specifications, consult your BREEZAIRE dealer for
assistance in choosing the correct unit. BREEZAIRE units are not warranted to cool a specific enclosure.

All interior walls and floor should have a vapor barrier and a minimum of R-11 insulation. All exterior wall's
insulation values should be a minimum of R-19. The ceiling should have vapor barrier and a minimum of R-19
insulation. The vapor barrier should be installed on the warm side of the insulation. There should be no glass
windows or doors.

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, rock 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 the fill gap between the door's frame
and wall before installing the cap 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.

SIZING GUIDE & SPECIFICATIONS

This guide is to be used only for enclosures meeting the above construction requirements.

INSTALLATION

BREEZAIRE recommends the use of a licensed refrigeration technician to install the WKS systems. Installation
of the unit's line set through a fire rated wall must be done in accordance with 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 are not designed to have duct systems attached to

either unit. Do not drill any holes into the cooling unit. This may damage the unit, promote rust, and will
void the warranty.

F Before installing the unit, inspect it again for any shipping damage. The WKS systems consist of two

components, the fan/coil unit (Figure 1) and the condensing unit (Figure 2). The condensing unit includes
the compressor, condenser coil, fan assembly, receiver tank and two service ports. The fan/coil unit
includes an internal, adjustable thermostat (48° to 62°F), solenoid valve, expansion valve, evaporator
coil, and fan assembly. The sight glass and strainer/dryer are separate pieces supplied with the unit.

F Mounting the fan/coil unit: The fan/coil unit should be mounted within six inches of the ceiling and as

close to the horizontal center of the wall as possible. If the unit must be mounted below the mid point of
the wall, exchange the upper front grill with the blank off plate on the top of the unit. (Figure 1) Airflow to
and from the unit must be unobstructed for a minimum of 3 feet. The unit is mounted to the wall using the
four slotted holes in the rear plate. The top holes should be approximately 10" from the ceiling. Mount
the unit to a solid part of the wall using ¼" lags or bolts. If necessary, attach two horizontal furring strips,
at least 1" thick, solidly to the studs and attach the unit to the furring strips. Provisions must be made for
passing the tubing set, wiring and drain tube through the wall.

F Mounting the condensing unit: Remember, unit installation location is not only important inside the wine

cellar, but just as important is where the condensing unit's warm exhaust air is being rejected. This is a
mechanical piece of equipment, it will make noise and produce heat from the warm exhaust air outlets
(Figures 2). Place the condensing unit on a solid foundation in a location with at least 1-foot of clearance
on all sides and the warm exhausting air to be unobstructed for at least 3 feet. This location should be an
area where the temperature is not higher than 90°F or lower than 20°F. (Note: Condensing units mounted
in areas with higher temperatures will degrade the performance of entire unit.) Inappropriate locations for
mounting the condensing unit includes laundry rooms, closets, bathrooms, garages, crawl spaces, attics
and humid basements. The condensing unit should be elevated to avoid any possible flooding and shaded
from direct sun light. Remove the screws and the upper cover. Do not open the access valves.

F Plumbing the system: The two units are connected by a 1/4 inch "liquid line" copper tube, and a 3/8

inch "suction line" copper tube. (Figure 1) The line-set should have a maximum calculated length of 100
ft. for each line. Reduce the line-set length by 10 feet for every 90° bend. [Calculated Length = Linear
length + 10 ft. for every 90' bend] (Note: Enclose both the suction [Gas] and discharge [Liquid] lines in
one flexible insulation jacket to promote heat exchange and prevent condensation from forming on the
lines.) Remove the cores from the access valves before soldering tubing to the valves. Caution: hold

charging valve assembly body with an appropriate wrench when removing or tightening the cap
or opening and closing the valve. The sight glass and strainer/dryer are separate pieces supplied with

the unit. The sight glass and strainer/dryer should be connected to the condensing unit's liquid line as
close as possible to unit.
