GENERAL DESCRIPTION
POLARIS SERIES Air Conditioners are designed for applications where outside air is not available
and spot cooling or air conditioning is needed. The cord connected Polaris Models range from 10500
BTU/HR to 60100 BTU/HR floor mount configuration to satisfy any space requirements. All models
are provided with casters for portability.
These models are thoroughly self-contained with the entire refrigeration system, water valve,
condensate pump, fan motor and electrical components neatly arranged in a platinum polyester powder
coated metal cabinet. Only power, condenser water supply and discharge and condensate drain piping
are required for installation. The 24 volt electronic temperature controller provides the desired comfort.
The high efficiency design of the water-cooled condenser allows the proper amount of water flow to
achieve the desired high and low refrigeration system pressures. Condenser water is regulated by a
refrigeration system head pressure actuated water regulating valve.
GENERAL REQUIREMENTS
A MINIMUM WATER PRESSURE OF 20 PSIG IS REQUIRED to actuate the water regulating valve
and allow water to flow into the condenser coil. The condenser water temperature leaving the unit
should not exceed 112° F. Ignoring this compliance will void the warranty on the refrigeration system.
IMPORTANT - Polaris Air Conditioners are designed and engineered for quiet comfort. The length
of service received can be extended by following the installation and preventive maintenance
instructions. 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
SERVICEABILITY
All Polaris Series units are designed with removable panels to provide full service accessibility. Turn to
page 11 “Part Replacement Procedure” for removal of the correct panel when replacing a part.
AUTOMATIC WATER VALVE
All units are equipped with a direct-acting, refrigeration system head pressure actuated water regulating
valve. This valve, factory set for 94° - 100° leaving water temperature (LWT), flows only the amount of
water required to achieve the desired refrigeration system operating pressure. Units used for closed loop
operation may be ordered without the water valve. If, however, the temperature of the return water is
questionable in a closed loop, the water valve may be helpful and left in the system with little pressure
drop.
ATTRACTIVE CABINET
The Polaris Series cabinet is constructed of 18 gauge cold rolled steel with a platinum polyester powder
coated finish that will compliment any decor. The entire cabinet is insulated with a sound absorbant insulation for cool, quiet comfort. The basepan is 14 gauge galvanized steel and remains dry and free from
odor and fungal growth.
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 for all Polaris models. 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 CONTROLS
The electronic thermostat displays room temperature if the cooling system is on. Select the temperature
you want by pressing the ▲ or ▼ buttons. (The word COOL and the temperature setting is displayed for
5 seconds). The FAN button controls the evaporator fan motor. In the ON selection, the fan runs continuously. In the AUTO selection, the fan cycles with the compressor. The OUTDOOR button is not used in
portable air conditioning. The MODE button controls the cooling function by selecting COOL or OFF.
The DAY/NIGHT allows day and night setpoints. A built in 4 minute time delay protects the compressor
from short cycling. Pressing the ▲ and ▼ simultaneously switches the display between Celsius and
Fahrenheit.
A two position rocker switch located next to the thermostat provides high fan when depressed at the top,
low fan speed when depressed at the bottom.
BUILT-IN CONDENSATE PUMP
Every unit is equipped with a condensate pump designed as an automatic condensate removal pump for
water dripping off the evaporator coil. The pump is capable of pumping against a 20 ft. 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 motor/pump failure should occur. The red condensate alert light on the front panel will be on
if this condition should occur.
CONDENSER COIL
The water cooled copper/steel tube-in-tube type condenser coil is designed for a maximum water side
working pressure of 400psi. Optional cupro-nickel condenser coils are available for severe duty and saltwater/brine applications. Low pressure drop and efficient design (high SEER’s) fully utilizes the heat
transfer capability of this compact coil.
FILTER
All units are equipped with a 1/2 inch thick, washable, foam air filter located behind the return air grille
that can easily be removed and cleaned. Just pull the grille out and remove the filter.
SERVICE CORD
All Polaris Series units are equipped with the standard ten foot long service cord with UL listed plug configurations. The following page contains Oceanaire plug configurations for all units.

OPTIONAL FEATURES
HOSE KIT
10, 25, and 40 foot hose kits with flare connectors to match fittings on units, banded 3-in-one design for
easy and convenient installation, are available. When using these hoses in applications with water pressures exceeding 50 PSIG, a water pressure reducing valve must be installed in the water supply line prior
to the hose kit; otherwise warranty on the hose kits will be void. The water out and condensate of the
three-section flexible plastic hose can be fed to a sink or permanent drain. When using a hose kit, avoid
sharp corners, hot water pipes and kinking to assure proper water flow of the supply and return lines.
HIGH PRESSURE WATER VALVE
High pressure water regulating valves, designed for use with up to 350 psig or 425 ±5 psig water inlet
pressure, are available.
CUPRO-NICKEL CONDENSER
When chemically treated water, salt water or brine is used in the condenser coil, it is recommended that
the air conditioner be equipped with a 90/10 Naval Spec. Cupro/Nickel condenser.
TREATED EVAPORATOR COIL
When airborne contaminants are a problem for air conditioning applications, acrylic coated evaporator
coils are recommended to guard against pitting or corroding.
