GENERAL INFORMATION
The OceanAire PAC series is a portable air-cooled spot cooler designed for
permanent or temporary cooling applications. The entire air conditioning unit
has been built in a premium sheet metal cabinet, equipped with heavy-duty
casters for mobility. All PAC models come standard with a 10-foot power cord
for electrical connection and added mobility in service. These spot-coolers are
designed to direct air to specific areas or objects through a discharge grille lo-
cated on the upper-front of the unit, while rejecting heat from the top of the unit.

BTU/HR to satisfy most space cooling requirements.
The PAC series is a self-contained unit with the entire cooling system (blower
assemblies, electrical and refrigerant components) neatly arranged in a gray
polyester powder coated metal cabinet. When connected to the proper source
of electrical power, a 24-volt thermostat controls the PAC unit to provide the
desired level of comfort and cooling.
A wide variety of accessories and factory installed options are available for the
PAC series allowing for improved performance and versatility.

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. When
power is connected to the unit, the thermostat will control 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. To protect the compressor
from short-cycling, there is a built-in time delay.
FAN SPEED CONTROL
A two position rocker switch, located next to the thermostat, provides the user with
the option of running the evaporator fan at high-speed or low-speed.
CONDENSATE TANK/PUMP
PAC series units come equipped with a means for handling the condensate gener-
ated during the cooling process. All units, except the PAC60 models, come
equipped with a condensate tank. The tank can be easily removed from the unit
and emptied as needed.
The PAC60 models come equipped with an Automatic Condensate Pump that re-
moves the condensate. 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 various installation requirements.
CONDENSATE ALARM LIGHT
On the front of all PAC models, there is a Condensate Alarm Light (RED) located
near the thermostat. For models other than PAC60, the light indicates that the con-
densate tank is full, and needs to be emptied. PAC60 units, the light indicates a
condensate pump over-flow condition where the pump is either disabled or restrict-
ed, and cannot remove the condensate water, and must be serviced.
FILTERS
All PAC series units are equipped with washable filters at the air intakes. Electro-
static mesh air filter located behind the evaporator return air grille serves to filter
the air before it is cooled. A 1/2” aluminum mesh filter serves to protect the con-
denser coil from dust build-up. Both filters can be easily removed and cleaned.
HIGH PRESSURE SAFETY SWITCH
Located on the back of the PAC 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 compressor can be re-started, once the condensing pressure has
equalized, by depressing the “RESET” button.
POWER CORDS
All PAC 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 a LCDI for
added safety features.

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.
AREA COOLER
When the PAC 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 PAC 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 PAC can then operate as a room air conditioner with the condenser air
isolated from the conditioned space.
