BREEZAIRE recommends the use of a licensed refrigeration technician to install the WKS2200.
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.
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.
If your installation cannot be performed in accordance with these instructions contact your dealer.
F
The WKS2200 consists of two components, the condensing unit and the fan/coil unit. The condensing unit includes the
compressor, condenser coil, fans, sight glass and two service ports. The fan/coil unit includes an internal, adjustable
thermostat (50°-62°F), capillary tube, filter drier, evaporator coil, and fans.
F
Mounting the fan/coil unit: The fan/coil should be mounted within six inches of the ceiling and as close to the
horizontal center of the wall as possible. Air flow to and from the unit must be unobstructed for a minimum of 3 feet.
The unit must be placed on a shelf capable of supporting the weight indicated in the specifications. Provisions must be
made for passing the tubing set, wiring and drain tube through the enclosure's wall.
F
Mounting the condensing unit: 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 and lower than 20°F. The condensing unit should be elevated to avoid
any possible flooding and shaded from direct sun light. Remove the screws and the cover.
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. The line-set should have a minimum linear length not less than 35 ft. and a maximum linear length no
longer than 100 ft. for each line. Reduce the line-set length by 10 feet for every hard 90° bend. Enclose the liquid and
suction line together in a flexible insulation jacket to allow heat exchange and to prevent condensation from forming on
the tube. If the condensing unit is mounted on a higher level than the fan/coil unit, a P-trap must be installed in the
suction line at the fan/coil's discharge. The fan/coil unit is equipped with a 3/8-inch OD drain tube for removal of water
from the condensate pan. Connect a 3/8-inch ID vinyl hose to the fitting and route the hose to an approved drain. A
condensate pump is required if the vinyl drain hose has any vertical rise.
F
Wiring the system: The WKS2200 fan/coil unit plugs into a standard 110 volt, 60 Hz properly grounded electrical
outlet. The circuit should be rated for a minimum of 5 amps. The condensing unit is wired to the fan/coil unit in
accordance with local building codes for interior or exterior conditions.
F
After all components have been connected, pressure test the complete system for a minimum of six hours. If no leaks
are found, evacuate the system through both the liquid and suction service ports for a minimum of six hours. With
electrical power connected to the fan/coil unit, slowly feed Refrigerant into the suction service port. Continue feeding
refrigerant until the sight glass becomes clear of bubbles. Allow the system to operate for several hours, check
refrigerant level in the sight glass again. Additional refrigerant may be required as the temperature of the
enclosure is lowered.
