GENERAL INFORMATION
The OceanAire 2OACH is a portable air-cooled heat pump designed for permanent or
temporary spot cooling or heating applications. The entire unit has been built in a
premium sheet metal cabinet, equipped with heavy-duty casters for mobility. All 2OACH
models come standard with a 10-foot power cord for electrical connection and added
mobility in service. These units direct heated/cooled air to specific areas or objects
through a discharge grille located on the upper-front of the unit, while rejecting cooled/
heated air from the top of the unit. The 2OACH models range in capacities from 12,000
BTU/HR to 60,000 BTU/HR to satisfy most space cooling or heating requirements.
The 2OACH is a self-contained unit with the entire system (evaporator and condenser
blower assemblies, electrical and refrigeration components), neatly arranged in a gray
and blue polyester powder coated metal cabinet. When connected to the proper source
of electrical power, the 2OACH is controlled by a solid-state electronic controller, with
numerous options of temperature and airflow controls that will provide the desired level
of comfort when cooling or heating.
A wide variety of accessories and factory installed options are available for the 2OACH
units allowing for improved performance and added versatility.
WARRANTY CARD
It is important that the warranty card be filled out completely and returned to the factory
within fourteen (14) days of installation of the unit in order to receive the benefits of the
warranty.

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. When power is
connected to the unit, the thermostat will control the unit to cool/heat a space to the
desired temperature. The thermostat is also capable of controlling the fan to operate
automatically when needed, or continuously.
One additional feature of the Deluxe Electronic Controller is that it will display a condition
alarm “CON”. “CON” displays when a condensate alarm, or a high pressure reset
condition has been met. To protect the compressor from short-cycling, there is a built-in
time delay. In the event of a power outage, all thermostat settings are saved, and the
unit will re-start automatically.
FAN SPEED CONTROL
One of the features of the electronic controller is that the unit supply fan can be
controlled either automatically or manually. In AUTO mode, the indoor blower will adjust
air flow automatically for added comfort and performance. Or, if desired, the controller
can be set to MANUAL fan mode, and the indoor blower will run continuously at one of
six levels of fan speed.
CONDENSATE TANK/PUMP
2OACH units come equipped with a means for handling the condensate generated
during the cooling/heating process. All units, except the 5-ton models, come equipped
with a condensate tank. The tank can be easily removed from the unit and emptied as
needed.
The 2OACH60 models come equipped with an automatic condensate pump. The pump
comes with a 20 foot long vinyl hose that allows for the removal of the condensate water
to a drain. The automatic pump is capable of a 20ft vertical lift, to handle almost any
installation requirement.
FILTERS
All 2OACH units 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/heated, 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 2OACH unit 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 the default setting “CON”. The compressor can then be re-started,
once the condensing pressure has equalized, by depressing the “RESET” button.
POWER CORDS
All 2OACH units come standard with a power cord for a convenient connection. All
models, except for the 3-phase units and 5-ton units, are equipped with LCDI for
added safety features.

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.
AREA COOLER
When the 2OACH is installed in an open area, the condenser exhaust duct directs the
warm air away from the space, allowing the evaporator air to cool the specific area.
ROOM AIR CONDITIONER
When ducted properly, the 2OACH can be used as a room air conditioner to cool an
enclosed space. Using the condenser return air plenum, additional ceiling kit, and other
accessories, the 2OACH can then operate as a room air conditioner with the condenser
air isolated from the conditioned space.

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.

SPECIAL NOTICE—THREE PHASE OPERATION
Models 2OACH3632, 2OACH3634, 2OACH6032 and 2OACH6034
All three-phase 2OACH models are equipped with a three-phase monitor for added
compressor protection. The phase monitor, located in the control box, has a
multi-color LED that reports status. The monitor protects the compressor from reverse
operation, phase loss, and low voltage situations. Further description of the
three-phase monitor is located in the electrical section of this manual.
NOTICE - DO NOT OPERATE ANY THREE-PHASE UNIT WHILE BYPASSING
THE MONITOR. THIS WILL VOID THE WARRANTY.
