GENERAL INFORMATION
The OceanAire CAC is a portable air-cooled spot cooler designed for permanent or
temporary spot cooling. The entire air conditioning unit has been built in a premium
sheet metal cabinet, equipped with heavy-duty casters for mobility. The CAC can be
operated as a stand-alone spot cooler, or can be permanently installed in a server rack,
or above a drop ceiling. The unit is equipped with a standard 10-foot power cord for
electrical connection and added mobility in service.
This spot-cooler is designed to direct air to specific areas or objects through a
discharge grille located on the upper-front of the unit, while rejecting heat from the back
of the unit. The CAC is a self-contained unit with the entire system, (evaporator and
condenser blower assemblies, electrical and refrigeration components) neatly arranged in
a black polyester powder coated metal cabinet. When connected to the proper source of
electrical power, the unit is controlled by a solid-state electronic controller, with
numerous options of temperature and airflow controls, that will provide the desired level
of comfort and cooling.
A wide variety of accessories and factory installed options are available for the CAC
model, allowing for improved performance and added versatility.

STANDARD FEATURES
CABINET
The CAC Series spot cooler has a cabinet that is constructed of 18 gauge steel with a
polyester powder coated finish. The matte black finish compliments any surrounding space,
and the cabinet is lined with sound-absorbing insulation for cool, quiet comfort. The CAC
comes equipped with handles and premium swivel casters for portability and convenient
set-up.
DELUXE ELECTRONIC CONTROLLER
The CAC unit is equipped with a deluxe electronic controller. When power is connected to
the unit, the thermostat will cycle the unit to cool a space to the desired temperature. The
thermostat is also capable of controlling the fan to operate automatically (when needed), or
continuously.
AUTO RESTART (FEATURE)
The controller has auto-restart capability. A built-in memory retains the settings, and the
unit will restart to the last set point automatically, after a power failure.
FAN SPEED CONTROL
One of the features of the electronic controller is that the unit supply fan can be controlled
automatically or manually. In AUTO mode, the evaporator blower will adjust air flow
automatically for added comfort and performance. Or, if desired, the fan speed can be set
to MANUAL mode, and the evaporator blower will run continuously at one of six levels of
fan speed.
CONDENSATE RESERVOIR/TANK
The CAC unit comes equipped with a Reservoir Tank for handling the condensate
generated during the cooling process. When the tank is full, the default condition “CON”
will be displayed. The tank can be easily removed from the unit and emptied as needed.
FILTERS
CAC’s are equipped with washable filters at the air intakes. Electrostatic mesh air filters
located behind the evaporator return air grille serve to filter the air before it is cooled, and
behind the condenser return air grille to prevent dust build-up. Both filters can be easily
removed and cleaned.
HIGH PRESSURE SAFETY SWITCH
Located on the back of the CAC is a manual re-set high pressure switch, used for the
protection of the compressor. If the condensing pressure exceeds the limit setting, the
switch will cycle the compressor off, while the evaporator fan remains running. The display
will indicate CON. The compressor can be re-started, once the condensing pressure has
equalized, by depressing the “RESET” button.
POWER CORDS
CAC units come standard with a 10-foot power cord, allowing for convenient connection
and portability. The power cord is equipped with a Leakage Current Detection Interrupt
(LCDI) device for added safety.

APPLICATIONS
The CAC can be used in an open environment to cool specific objects or "spots". Spot
Cooling is a convenient and economical way to provide air conditioning where cooling the
entire space is impractical. Cool air is discharged from the unit and is directed where it is
needed. Nozzle kits can be used for directional cooling.
ROOM AIR CONDITIONER
When ducted properly, the CAC can be used as a room air conditioner to cool an
enclosed space. Using the condenser return air panel (CCP-8) and ceil ing di sc harge
kit (CK-8)), the CAC c an operate as a room air condi tioner with the condenser air
isolated form the conditioned space.
CEILING MOUNT
The CAC can be secured above a space, or be installed above a drop ceiling, allowing
the unit to cool a room/area without taking up any valuable floor space.
RACK MOUNT
The CAC can be rack mounted inside a 19-inch computer rack, occupying just 12U of
rack space.

GROUNDING TYPE CONNECTOR (LOAD FITTING).
PERMANENT INSTALLATION
The CAC can be installed in a permanent configuration, as the control box is suitable for
field wiring. The unit can be hung from 5/16” threaded rods, or be installed with the use
of UniStrut. Instructions for Permanent installations are on Pages 8 and 9 in the manual.
When hanging and permanently connecting the CAC, all applicable
local/state/federal building codes must be followed.
The structural beam(s) must be capable of properly supporting the weight
of the unit (135 lbs.)

CONDENSATE TANK
The CAC has a 2-gallon polyethylene tank for collecting condensate. The tank is located
in the lower, front section of the unit. When the high water is reached, a cut-out switch will
AUTOMATICALLY cycle off t he compressor/co ndenser fan. The evaporat or fan w il l
continue to run and circulate the air.

EMPTYING THE CONDENSATE RESERVOIR TANK
In the COOL Mode, condensate will collect in the condensate tank. When the tank is
full, the Deluxe Controller will shut down the compressor and the fault “CON” will be
displayed, along with the room temperature. To empty the tank, do the following:
1. Press the POWER button, to turn the unit off.
2. Remove the tank from the lower front of the unit, using the handle.
3. Remove the rubber stopper, and empty the tank in a nearby sink.
