STANDARD FEATURES
SERVICEABILITY
All 2OAC/OACH Series units are designed with quick connect removable side panels to provide full
service accessibility. Only one screw needs to be removed for access to the inside of the unit. Turn to
page 17 “Part Replacement Procedure” for removal of the correct panel when replacing a part. The
interior is divided into two sections, front and rear. The front section contains the evaporator blower, coil,
condensate bucket and thermostat. The rear section contains the condenser blower, coil, compressor,
electrical control box and cord storage box.
ATTRACTIVE CABINET
The 2OAC/OACH Series cabinet is constructed of 18 gauge cold rolled steel with a gloss grey and blue
texture polyester powder coated finish that will compliment any decor. The entire cabinet is insulated
with a sound absorbant insulation for cool, quiet comfort.
HIGH PRESSURE SAFETY SWITCH
All units incorporate a manual re-set high pressure switch for maximum protection of the refrigeration
system and compressor. The cut-out pressure setting is 375 ±5 psig or 425 ±5 psig. If the pressure
exceeds this setting, the compressor stops and can be re-started by depressing the “RESET” button
located on the back panel of the unit. The high pressure control’s capillary line is attached to a schrader
valve. This allows replacement of a defective control without recovering the refrigerant.

STATE-OF-THE-ART CONTROL SYSTEM
This self diagnostic control system handles more than just temperature. The ConvertibleAire (2OACH)
has automatic changeover from heating to cooling and cooling to heating. The ArcticAire (2OAC) does
not since it is a cooling only model. The temperature setpoint range is from 55°F to 85°F.
A built-in time delay prevents compressor short cycling.
The built-in 6 speed fan controller decreases the fan speed as the temperature approaches the setpoint.
The LED display will read the return and supply air temperature...as well as setpoint.
MOISTURE MODE
When entering the moisture mode with the select button the fan will start within 1 minute at speed level 3.
The fan will run for 30 minutes sampling the air temperature and storing it into memory. If the ambient
air temperature is above 60°F, the compressor will then start. The compressor will run for a maximum of
one (1) hour, or until there is a 2°F drop in ambient temperature. After the compressor shuts off, the
evaporator fan will continue to run for four (4) more minutes, then turn off. This cycle will start again in
four (4) hours. The right most decimal is lit while the compressor is running. If the unit is properly sized
for the conditioned space, this process should maintain the relative humidity between 50-60%.
FILTERS
The condenser coil filter is 1/4 inch thick washable foam located in the filter grille assembly in the back
of the unit. The evaporator filter is 1/4 inch thick washable foam located in the filter grille assembly in the
front of the unit. To remove filter: (1) lift and pull out the filter grille. (2) pull the filter away from the
velcro attaching strip. (3) wash, and re-install in reverse order. The filter may be reinstalled damp since
the air flow will dry it quickly.
SERVICE CORD
All ArcticAire (2OAC) and ConvertibleAire (2OACH) Series units are equipped with a standard ten (10)
foot long service cord with plug configurations and receptacle requirements as shown in the chart below.

CONDENSATE RESERVOIR TANK
ArcticAire (2OAC) and ConvertibleAire (2OACH) utilize a 5.0 gallon capacity, polyethylene condensate
drain tank, located in the lower, front section of the unit behind the tank door. 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.
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 clockwise.

A condensate pump kit designed as an automatic condensate removal system for water dripping off of the
evaporator coil is available. This pump kit can be used in place of the condensate collection tank, which is
standard on every model except the 5-ton, where a condensate pump is standard equipment.
It is a convenience for those who do not want to empty the 5.0 gallon condensate tank. It is very
convenient on units that are permanently installed.
This pump is capable of pumping against a 20 foot head and is controlled by a float/switch mechanism
which turns the pump "on" when approximately 2 1/2 inches of water collects in the tank and
automatically switches "off" when the tank drains to a level of approximately 1 1/4 inches. A built-in
pump safety switch turns off the air conditioner if the condensate line becomes plugged or pump motor
failure should occur. A built-in check valve prevents drain back and short cycling of the pump.
The pump kit includes tubing,
mounting bracket,
hardware , wi r i ng
and insulated
mounting base.
Pump kit installs in place
of the condensate bucket
located behind the door
Pump Kit
on the front of the unit.

The Quick Connect Condensate Pump may be
easily installed for one job, and just as easily
reinstall the bucket for the next job. Our quick
connect kit consists of our specially prepared
and wired condensate pump, 20 feet of 3/8
plastic tubing, 2-10 inch pieces of 3/8 drain
hose, 1 hose clamp, and 2 attaching screws.

CONDENSER INLET AIR PLENUM
2DCP, Condenser Plenums are used to duct condenser air into the unit. The plenum easily
attaches with speed screws (supplied) to the back of the unit. The plenum transitions the
condenser inlet air opening to 12 inch round on Size 12, 18, 24 and 36. The Size 60 transitions
into 2, 12 inch round inlet ducts.
To calculate “equivalent feet”, add the length of the condenser inlet air duct run and the length of
the condenser air discharge duct run...allowing for elbows( adding 6 equivalent feet per 90°
(elbow). This is total equivalent feet. At any rate, do not exceed the rated E.S.P.(External Static
Pressure).
Condenser air plenums can substantially reduce air noise and increase the number of options for
solving difficult cooling problems.
All 2OAC/2OACH units have a dedicated blower for the condenser section and a dedicated
blower for the evaporator section. So, the “equivalent feet” may be applied to either or both
sections of the unit at the same time.

APPLICATIONS
ROOM AIR CONDITIONER/HEAT PUMP
OceanAire ArcticAire and ConvertibleAire units can be used as a room air conditioner to cool the
entire enclosed space. In this application, condenser hot exhaust air venting and condenser air
intake ducting is required. Use the optional "Flexible Duct" and the "Condenser Inlet Air
Plenum" as specified in the optional features section. ConvertibleAire units can be used to heat a
space to a desired temperature, but, not warmer than 85° F. If a condenser inlet air plenum is not
used, negative pressure created in the space by the condenser blower may cause a net temperature
increase in the room. Please consult your Oceanaire distributor or factory for assistance.
SPOT COOLER/HEATER
ArcticAire/ConvertibleAire units can be used in an open environment to cool specific objects or
"spots" through the evaporator grille, the optional nozzles or the optional duct adapter. Spot
Cooling is a convenient and economical way to provide air conditioning where cooling the entire
space is impractical. In this application, ducts for condenser air intake and hot air exhaust are not
often not required. If heating cool spots are required, ConvertibleAire units may be used in the
“heating” mode.
AREA COOLER/HEATER
When ArcticAire or ConvertibleAire is installed in an area that is not totally enclosed, the
(optional) condenser hot air exhaust duct directs condenser air out of the area, allowing the
evaporator air to cool the specific space.
INSTALLATION INSTRUCTIONS
BEFORE INSTALLING: Check the air conditioner/spot cooler for any damage. Air conditioners
are thoroughly inspected at the factory and carefully packaged. If any damage is evident, file a
claim with the delivering carrier immediately.
ELECTRICAL REQUIREMENTS: Check the data plate on the back of the unit to make certain
that the proper power is available. Refer to "Specifications" section for voltage and fuse/circuit
breaker requirement. For proper NEMA receptacles, refer to "Electrical service plug
configuration". Operating the unit on improper voltage will void the warranty. Caution: An
extension cord can be used provided it is rated at least 20 amps@ 120 volts, or 20 amps@ 250
volts with grounding-type attachment plug and grounding type connector (load fitting). For
Models 2OAC/2OACH6012 at least 50 amps@ 250 volts and for Models 2OAC/2OACH6032 at
least 30 amps@ 250 volts 3 phase.
OceanAire ArcticAire/ConvertibleAire portable air conditioner/spot cooler/heater requires
minimal installation. Plug unit in proper NEMA receptacle and it immediately begins to cool or
heat. The entire system is built into one compact unit which can be moved and installed with
ease.
DO NOT INSTALL UNIT AGAINST A WALL. A MINIMUM OF 8 INCHES OF
CLEARANCE IS REQUIRED BETWEEN THE WALL AND THE BACK OF THE
UNIT.

PREVENTIVE MAINTENANCE
2OAC/OACH Series air conditioners 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:
1. BLOWER MOTOR ASSEMBLY
The motors for all models are sealed and require no oiling. Dust and
dirt may be removed from the motor vanes by washing, blowing with
an air hose or with a vacuum.
2. FILTERS
A clogged filter will cause the unit to operate at greatly reduced efficiencies. We recommend that the
filter be inspected on a regular bases every six weeks or more often depending on the environment.
The Evaporator washable foam filter is located behind the return air grille and can be easily removed
by pulling the grille out. The condenser washable foam filter is located in the grille on the back of the
unit. Remove the grille by lifting it out. The filter can then be removed for washing. The filters must
be washed periodically or as needed.
3. CONDENSATE PUMP
When servicing pump follow these steps;
1. Make certain that the unit is disconnected from the power source before attempting to service or
remove any component.
2. Be sure the floats move freely. Clean as necessary.
3. Remove the volute and check for obstructions. Clean as needed.
4. Clean the tank with warm water and mild soap when mineral deposits are visible.
5. Check the inlet and outlet piping. Clean as necessary. Be sure there are no kinks in the lines that
would inhibit flow.
GENERAL
When necessary maintenance steps outlined above are followed, the air conditioner will provide long
and reliable service. The refrigeration and electrical circuits of the system should only be serviced by
a fully qualified service technician.

NOTE:
Compressor has only one
proper rotation direction. If
compressor is unusually noisy and
does not cool, it may be running
backwards. This is not unusual for
3 phase equipment.
TO CORRECT THIS:
Unplug power cord from outlet,
remove side panel at electrical box
and reverse any two of the power
leads on the compressor contactor.
Example, move L1 wire to L2.
And move L2 wire to L1. Reinstall side panel, plug unit in and
re-start.
