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.

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.
APPLICATIONS SPOT COOLER 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.
ELECTRICAL CONFIGURATION PORTABLE CONFIGURATION The CAC is equipped with a 10-foot power cord for ease of movement and portability. The cord is to be plugged into a 15 Amp receptacle. A dedicated circuit is required. MODEL CAC PLUG CONFIGURATION RECEPTACLE 15A-125 VOLT NEMA 5-15P NEMA-5-15R SERVICE CORD The CAC is equipped with a 10-foot long service cord with a LCDI (Leakage Current Detection & Interruption) device that serve as a means of electrical protection.
CONDENSATE 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 the compressor/condenser fan. The evaporator fan will continue to run and circulate the air.
INSTALLATION INSTRUCTIONS RECEIVING—INSPECTION Upon receiving your CAC unit, inspect the packaging for any damage. All units are shipped on a skid, and packaged in a triple-wall carton for added protection. BEFORE INSTALLING Check the unit for any damage. All OceanAire products are thoroughly inspected at the factory and carefully packaged. If any damage is evident, contact OceanAire IMMEDIATELY.
INSTALLATION—HANGING APPLICATION The CAC may be suspended above a space, or installed above a drop ceiling. The unit can be hung from a building’s structural beam by one of three means: INSTALL (4) 5/16-18 THREADED RODS INTO TOP PANEL OF UNIT Using 5/16” -18 threaded rods secured into the top of the unit at the 4 corners. Make sure there is a minimum of 1/2” thread engagement into panel nuts. Rods are to be secured to upper structure by means of washers and nuts. Using 12 ga.
INSTALLATION—PERMANENTLY CONNECTED The CAC power cord can be removed and permanently connected to a power source. Once the CAC is installed and secured for a stationary installation, the unit can be permanently wired. 1. Remove the left side panel and locate the power cord/strain relief at the rear of the unit. 2. Disconnect the power cord from the ground lug and terminal strip. 3. Remove the power cord and the strain relief. 4. Install 1/2” conduit and a UL recognized bushing through the 7/8” DIA.
INSTALLATION—STACKING KIT SK-1 Two or three Cool Cube units are needed when: REDUNDANCY IS NEEDED COOLING LARGE AREAS HIGH HEAT LOADS and only a small amount of floor space is available. The CAC can be stacked on top of each other to produce a capacity of 24,000 or 36,000 BTU/H, while maintaining the same foot print. To facilitate the stacking of the Cool Cube units, a stacking kit SK-1, is required for each additional unit. 1. Disconnect Power before Servicing 2.
INSTALLATION—RACK MOUNTING KIT RCK-1 The 19-Inch Rack Kit allows for the Cool Cube to be installed into any EIA-310-D, 4-Post or 2-Post rack enclosure. The kit includes: (2) heavy duty rails, (4) side mounting brackets, and a rear mounting rail. The rails have a vibration dampening foam layer secured to the top for noise reduction. The hardware included in the kit will accommodate most installations, such as square hole racks, 12-24 threaded racks, 10-32 threaded racks and round hole racks. 1.

CONDENSER DISCHARGE ACCESSORIES CEILING PANEL CEILING PANEL DUCT KIT, CK-8 A ceiling panel kit is available for discharging the condenser air above a drop ceiling. The ceiling panel duct kits are furnished with an 8-inch white vinyl coated flexible duct that allows for convenient installation. A 2ft X 2ft ceiling duct-panel is included to replace a 2ft X 2ft drop-ceiling panel where the connection is desired.
ACCESSORIES CONDENSATE PUMP KIT , CPC-1 The condensate pump provides for the automatic removal of condensate water during the cooling process. The pump is capable of pumping against a 20 foot height, allowing for the routing of the drain line above the drop-ceiling to a nearby drain. The pump is controlled by an internal float-switch/check valve which turns the pump on and off automatically.
ACCESSORIES DISCHARGE AIR NOZZLE KIT ASSEMBLY, CNK-1 The optional discharge nozzle kits are used to direct the conditioned air to a specific target area. By concentrating the airflow, the nozzles increase the air velocity towards production lines to cool personnel and/or equipment. In server rooms, the nozzles can be used to direct airflow through the rack to remove the hot air from the area of the equipment.
ACCESSORIES EVAPORATOR RETURN AIR PLENUM, CEP-6 An evaporator return air plenum is available for installations where it is required to duct air to the inlet of the evaporator. The return air plenum allows the user to connect round duct (flexible or rigid) to the return air intake and reduce air noise, while increasing the number of options for solving difficult cooling problems. The plenum attaches to the front of the unit, replacing the return air grille.
DELUXE ELECTRONIC CONTROLLER The CAC controller is equipped with many features for a more precise level of cooling and operation. Additionally, the controller can be removed from the unit and installed for remote operation, if needed (accessory parts may be required). POWER button OCEANAIRE DELUXE ELECTRONIC CONTROLLER When power is connected, the controller will display “888” momentarily, and will then disappear. Press the POWER button, then press the TEMP SELECT button until the SET POINT is displayed.
FAN SPEED—The operator can select between AUTO or MANUAL fan speed control. Pressing the FAN SPEED button, will switch speed from AUTO to MANUAL. In MANUAL mode, pressing the FAN SPEED button will change fan speed from low to high. In AUTO mode, the fan speed is controlled automatically. In cooling mode, the controller automatically adjusts the fan speed to high, and as the inside temperature approaches the set point, the fan speed will reduce.
