STANDARD FEATURES CABINET The PAC series cabinet is constructed of 18 gauge steel with a gray polyester powder coated finish that will compliment any decor. The entire cabinet is insulated with sound- absorbing insulation for cool, quiet comfort. All units come equipped with handles and swivel casters for portability and convenient set-up. ELECTRONIC THERMOSTAT All PAC units are equipped with a non-programmable electronic thermostat.
APPLICATIONS COOLING MODE—SPOT COOLER The PAC 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.
ELECTRICAL CONFIGURATION SERVICE CORD All PAC series units are equipped with a standard 10-foot long service cord with plug configurations and receptacle requirements as shown in this chart. PAC1211, PAC1811, PAC2412 and PAC3612 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 PAC1211 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 PAC1811 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 PAC2412 AN EXTENSION CORD CAN BE USED, PROVIDED IT IS RATED AT LEAST 20 AMPS @ 250 VOLTS WITH GROUNDING-TYPE AT
CONDENSATE For Models PAC1211, PAC1811, PAC2412, AND PAC3612, 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 PAC12,18, 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 to remove the hot air from the area of the equipment.
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 plenums allow the user to connect round ducts (flexible or rigid) to the return air intake to reduce air noise and increase the number of options for solving difficult cooling 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 be installed for either vertical or horizontal ducting. The standard discharge grille is removed and the DDA is attached in the grille opening. 2DDA-6 for PAC1211, converts the evaporator discharge to a 6-inch diameter round duct.
INSTALLATION INSTRUCTIONS RECEIVING—INSPECTION Upon receiving your PAC 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.
THERMOSTAT OPERATION FAN SLIDE SWITCH The FAN Slide Switch allow you to set the fan mode from ON (fan is on all the time) to AUTO (fan cycles under thermostat control) MODE SLIDE SWITCH To turn the unit ON, slide the Mode Slide Switch down to the COOL position. To turn the unit OFF, slide the Mode Slide Switch to the OFF Position. TEMPERATURE BUTTONS Once the MODE switch has been put into the COOL mode, push the corresponding arrow button to lower or raise the set point to the desired temperature.
REPLACEMENT PROCEDURE FOR PARTS IT IS RECOMMENDED THAT ALL OCEANAIRE UNITS BE SERVICED BY A QUALIFIED AIR CONDITIONING SERVICE TECHNICIAN WARNING—TO AVOID INJURY, DISCONNECT UNIT POWER PRIOR TO SERVICING A. FAN MOTORS 1. Remove cabinet left-side panel (when looking at the front of the unit). 2. Evaporator fan motor—disconnect evaporator motor wires from evaporator fan contactor and fan speed rocker switch. Condenser fan motor—disconnect condenser motor wires from condenser fan contactor. 3.
TROUBLESHOOTING GUIDE The following steps and procedures are recommended for correcting the problems indicated. In the event that the problem can not be corrected, service may be required. SERVICE SHOULD BE PERFORMED BY A QUALIFIED AIR CONDITIONING SERVICE TECHNICIAN PROBLEM: UNIT DOES NOT POWER UP CAUSE: Power interruption REMEDY: Check LCDI (on models with LCDI), and reset LCDI. Check external power supply making sure that the disconnect is ON. Check for blown fuses or tripped circuit breakers.
PREVENTIVE MAINTENANCE PAC series Spot Coolers are designed to last a long time, and to give maximum performance and reliability with minimum maintenance. To prolong the life of the unit, regular maintenance must be performed as specified below: BLOWER MOTORS The motors on all units have permanently lubricated bearings. No oiling is necessary FILTERS A clogged filter will cause the unit to operate at greatly reduced efficiencies.

THREE PHASE MONITOR Three-Phase units are equipped with monitors for motor protection. The Oceanaire Three-phase Monitor safeguards the unit against incorrect compressor rotation, low-voltage and/or loss of power in any one of the power legs. The monitor is installed in the control box and is equipped with an LED for diagnosis of an improper electrical condition (see diagrams below). When power is connected, the compressor WILL NOT engage until the monitor start delay has timed out.
