STANDARD FEATURES CABINET The 2OACH Series heat pump has a cabinet that is constructed of 18 gauge steel with a polyester powder coated finish that will compliment any decor. The cool blue front compliments any surrounding space, and is insulated with sound-absorbing insulation for cool, quiet comfort. All units come equipped with handles and premium swivel casters for portability and convenient set-up. DELUXE ELECTRONIC CONTROLLER Each 2OACH unit is equipped with a deluxe electronic controller.
APPLICATIONS COOLING MODE—SPOT COOLER The 2OACH 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.
APPLICATIONS HEATING MODE—HEAT PUMP In HEAT mode, The 2OACH can be used in an open environment to provide heat to a specific area or "spots". The 2OACH is a heat pump, and the supply air will feel warm, but not extremely hot to the touch. Nozzle kits can be used for directional heating.
ELECTRICAL CONFIGURATION SERVICE CORD All 2OACH-Series units are equipped with a standard 10-foot long service cord with plug configurations and receptacle requirements as shown in this chart. 2OACH1211, 2OACH1811, 2OACH2412 and 2OACH3612 units come with LCDI (Leakage Current Detection & Interruption) devices that serve as a means of electrical protection. CAUTION DO NOT USE THE LCDI AS AN ON/OFF SWITCH FOR THE UNIT All 3-phase models are equipped with locking plugs for added connection reliability.
USE OF EXTENSION CORDS CAUTION FOR MODEL 2OACH1211 AN EXTENSION CORD CAN BE USED, PROVIDED IT IS RATED AT LEAST 15 AMPS @ 115 VOLTS WITH GROUNDING-TYPE ATTACHMENT PLUG AND GROUNDING TYPE CONNECTOR (LOAD FITTING) FOR MODEL 2OACH1811 AN EXTENSION CORD CAN BE USED, PROVIDED IT IS RATED AT LEAST 20 AMPS @ 115 VOLTS WITH GROUNDING-TYPE ATTACHMENT PLUG AND GROUNDING TYPE CONNECTOR (LOAD FITTING) FOR MODEL 2OACH2412 AN EXTENSION CORD CAN BE USED, PROVIDED IT IS RATED AT LEAST 20 AMPS @ 250 VOLTS WITH GROUNDING-TYP
CONDENSATE For Models 2OACH1211, 2OACH1811, 2OACH24 and 2OACH36, a 5-gallon polyethylene tank is provided to collect condensate. The tank is located in the lower front section of the unit, and can be accessed though the condensate tank door. When the high water level is reached, a cut-out switch will AUTOMATICALLY cycle off the compressor/condenser fan.

ACCESSORIES 2 x 2 CEILING DUCT-PANEL CEILING PANEL DUCT KIT A ceiling panel kit is available for discharging the condenser air above a drop ceiling. The ceiling panel duct kits are furnished with a 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. VINYL COATED FABRIC DUCT DUCT STRAP The CK-12 is available for 2OACH12, 18, and 24.
ACCESSORIES DISCHARGE AIR NOZZLE KIT ASSEMBLY 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 the airflow through the rack, and remove the hot air from the equipment area.
ACCESSORIES CONDENSER RETURN AIR PLENUM Condenser return air plenums are available for installations where it is required to duct air to the inlet of the condenser. The plenum easily fits into place on the back of the unit, and is provided with a flange for connecting 12-inch or 16-inch flexible ducting. A condenser return air plenum can substantially reduce air noise and allow the unit to operate without drawing condenser air from the conditioned space.
ACCESSORIES EVAPORATOR RETURN AIR PLENUM Evaporator return air plenums are available for installations where it is required to duct air to the inlet of the evaporator. The evaporator return air plenum allows the user to connect round duct (flexible or rigid) to the return air intake to reduce air noise and increase the number of options for solving difficult application problems. The plenum attaches to the front of the unit, replacing the return air grille.
ACCESSORIES DISCHARGE DUCT ADAPTER Discharge duct adapters are available for applications where ducted evaporator discharge is required. The adapters can be easily installed on the unit without fasteners, and can be used for either vertical or horizontal ducting. The standard discharge grille is removed and the 2DDA is attached in the grille opening. 2DDA-6 for model 2OACH12, converts the evaporator discharge to a 6-inch diameter round duct.
INSTALLATION INSTRUCTIONS RECEIVING—INSPECTION Upon receiving your 2OACH 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.
DELUXE ELECTRONIC CONTROLLER The 2OACH controller is equipped with many features for a more precise level of comfort 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.
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.
2OACH PROGRAM SETTINGS MODEL CODE SETTINGS 2OACH12 P1 = 65, P2 = 45 2OACH18 P1 = 80, P2 = 50 2OACH24 P1 = 70, P2 = 50 2OACH36 P1 = 85, P2 = 40 2OACH60 P1 = 85, P2 = 45 NOTICE Program Parameters are NOT controller default values.
REPLACEMENT PARTS PROCEDURE IT IS RECOMMENDED THAT ALL OCEANAIRE UNITS BE SERVICED BY A QUALFIED AIR CONDITIONING SERVICE TECHNICIAN WARNING—TO AVOID INJURY, DISCONNECT UNIT POWER PRIOR TO SERVICING A. FAN MOTORS 1. Remove cabinet's left-side panel (when looking at the front of the unit). 2. Evaporator fan motor—disconnect evaporator motor wires from evaporator fan contactor and power module.
