GENERAL DESCRIPTION
The Oceanaire CONVERTIBLEAIRE is a portable air-cooled heat
pump designed for permanent or temporary spot cooling or heating
applications. The entire air conditioning unit has been built in an
premium sheet metal cabinet, equipped with heavy-duty casters for
mobility. All CONVERTIBLEAIRE models come with a 10-foot power
cord for electrical connection and added mobility in service. These
heat pumps direct cooled or heated air to specific areas or objects
through a discharge grill located on the upper-front of the unit, while
rejecting heat/cool from the top of the unit. The CONVERTIBLEAIRE
models range in capacities from 12,000 BTU/HR to 60,000 BTU/HR
to satisfy most space cooling or heating requirements.
The CONVERTIBLEAIRE is a self-contained unit with the entireheat
pump system, evaporator and condenser fan motors and electrical
components neatly arranged in a gray and blue polyester powder
coated metal cabinet. When connected to the proper source of electrical power, the CONVERTIBLEAIRE 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 CONVERTIBLEAIRE 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.

STAN DARD FEATURES
CABINET
The CONVERTIBLEAIRE 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 soundabsorbing insulation for cool, quiet comfort. All units come equipped with handles and
premium swivel casters for portability and convenient set-up.
DELUXE ELECTRON I C CONT RO LLER
Each CONVERTIBLEAIRE unit is equipped with deluxe electronic controller. 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.
One additional feature of the Deluxe Electronic Control 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.
FAN SPEED CONTROL
One of the features of the electronic controller is that the unit supply fan can be controlled automatically or manually. In AUTO mode, the indoor blower will adjust air flows
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 RESERVOIR/ PUMP
CONVERTIBLEAIRE units come equipped with a means for handling the condensate
generated during the cooling/heating process. All models except the 5-ton models
come equipped with a Condensate Reservoir Tank, that captures the condensate from
cooling. The tank can then be easily removed from the unit and emptied as required.
The 2OACH60 models come equipped with an Automatic Condensate Pump that disposes of the condensate. The pump comes with a 20 foot long vinyl hose that allows for
the disposal of the condensate water to a drain. The automatic pump is capable of a
20ft lift, to handle almost any installation requirement.
FILTERS
All CONVERTIBLEAIRE units are equipped with washable filters at the air intakes. Electrostatic mesh air filters located behind the evaporator return air grill serve to filter the air
before it is cooled, and behind the condenser return air grill to prevent dust build-up.
Both filters can be easily removed and cleaned.
HIGH PRESSURE SAFETY SWITCH
Located on the back of the CONVERTIBLEAIRE 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 cut-out shuts down the compressor, while the evaporator fan re-
mains running. The display will indicate CON. The compressor can be re-started, once
the condensing pressure has lowered, by depressing the “RESET” button.
POWER CORDS
All CONVERTIBLEAIRE units come with power cords, convenient connection and portability. All units except the 5-ton models, and 3-phase models are equipped with LCDI
for added safety devices.

APPLICATIONS
COOLING MODE—SPOT COOLER
The CONVERTIBLEAIRE 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 to improve direction of the cooling airflow.
AREA COOLER
When the CONVERTIBLEAIRE is installed in an area that is not totally enclosed,
the condenser hot air exhaust duct directs condenser air out of the area, allowing
the evaporator air to cool the specific space.
ROOM AIR CONDITIONER
When ducted, the OceanAire CONVERTIBLEAIRE can be used as a room air
conditioner to cool an enclosed space. Using the condenser return air plenum
(2DCP) and ceiling discharge kit (CK) and ceiling panel kits CK-PL accessories,
the 2OACH can operate as a room air conditioner with the condenser air isolated
form the conditioned space.

APPLICATIONS
HEATING MODE—HEAT PUMP
in HEAT mode, The CONVERTIBLEAIRE can be used in an open
environment to provide heat to a specific area or "spots". The
CONVERTIBLEAIRE is a heat pump, and the supply air will feel warm, but
not extremely hot to the touch. Nozzle kits can be used to improve direction
of the heated airflow.

Models 2OACH3632, 2OACH3634, 2OACH6032 and 2OACH6034
All three-phase CONVERTIBLEAIRE models are equipped with a
three-phase monitor for added compressor protection. The phase
monitor, located in the control box, has 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 the manual.
NOTICE - DO NOT OPERATE ANY THREE-PHASE UNIT BY BYPASSING THE MO N ITOR, THI S WILL VOID THE WARRANTY

CONDENSATE RESERVOIR TANK
For Models 2OACH12, -18, -24 -36, a 5-gallon polyethylene tank is provided standard, to
collect condensate. The tank is located in the lower, front section of the unit. A high
water level cut-out switch is used to stop the compressor and condenser fan automatically
when the tank's pre-set water level has been reached. The evaporator fan will continue to
run, circulating air. The control display will read “CON”
TANK LEVEL ADJUSTMENT INSTRUCTIONS
An adjustment screw is provided to vary the cut-off of the tank full switch. If a lighter (less
weight) level of water is desired, turn the adjusting screw clockwise. Do not exceed 6 full
turns counter-clockwise.
CAUTION, TURN UNIT OFF: BEFORE ADJUSTING SET SCREW
BEFORE REMOVING TANK TO EMPTY CONDENSATE
Turn screw clockwise to lower water level. Less water makes tank lighter and easier to
remove.
NOTE: Max. and Min. water levels shown are those at which the unit will shutdown and
not restart until the condensate tank has been drained.
