GENERAL DESCRIPTION

ARCTICAIRE and CONVERTIBLEAIRE SERIES Portable Air-Cooled Air Conditioners and heat
pumps are designed to cool or heat an entire area by discharging air through their 12 x 5 grille (Models
2OAC12 and 2OACH12) 14 x 8 1/2 (Models 2OAC/2OACH18, 24), 18 X 10 (Model 2OAC/
OACH36) and 18 x 12 (Models 2OAC/2OACH60). These self contained units are also designed to
direct air to specific areas or objects through (optional) dual 4 in. diameter nozzles (Model
2OAC/2OACH12) and 6 in. diameter nozzles (Models 2OAC/2OACH18, 24 ,36), and 8 in. diameter
nozzles (2OAC/2OACH60). The cord connected Models range from 13,500 to 60,000 BTU/HR cooling

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

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.
