PREVENTIVE MAINTENANCE
ARCTICAIRE Spot Coolers 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:
BLOWER MOTORS
The motors on all units have permanently lubricated bearings. No oiling is necessary
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 filter is located behind the return air grille
and can be easily removed and cleaned. The condenser filter is located in the lower
backside of the unit. Remove by loosening one screw holding retaining clip and pull out.
The filters must be washed periodically as needed by placing them in a dishwasher or
soaking them in a solution of warm water and detergent for 10 minutes. Then rinsing them
clean with hot water and shaking excess moisture from filter.
CONDENSATE PUMP
Condensate pumps come standard on all Size 60 models, and may be installed as op-
tions on size 12, 18, 24 and 36 models. 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.
STANDARD FEATURES
CABINET
The CAC1211 Series spot cooler has a cabinet that is constructed of 18 gauge steel with
a polyester powder coated finish. The matte black finish compliments any surrounding
space, and the cabinet is lined with sound-absorbing insulation for cool, quiet comfort.
The CAC1211 comes equipped with handles and premium swivel casters for portability
and convenient set-up.
DELUXE ELECTRONIC CONTROLLER
The CAC1211 unit is equipped with deluxe electronic controller. When power is con-
nected to the unit, the thermostat will control the unit to cool a space to the desired tem-
perature. The thermostat is also capable of controlling the fan to operate automatically
(when needed) or continuously.
AUTO RESTART (FEATURE)
The controller has auto-restart capability. A built-in memory retains the settings, and the
unit will restart to the last set point automatically, after a power failure.
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 evaporator blower will adjust air flow auto-
matically for added comfort and performance Or if desired, the fan speed can be set to
MANUAL mode and the evaporator blower will run continuously at one of six levels of fan
speed.
CONDENSATE RESERVOIR/TANK
The CAC1211 unit comes equipped with a Condensate Reservoir Tank for handling the
condensate generated during the cooling process. When the tank is full, the word CON
will be displayed. The tank can be easily removed from the unit and emptied as required.
FILTERS
CAC1211’s 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 CAC1211 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 remains running. The dis-
play will indicate CON. The compressor can be re-started, once the condensing pressure
has lowered, by depressing the “RESET” button.
POWER CORDS
CAC1211 units come with a 10 ft. power cord, allowing for convenient connection and
portability. The power cord is equipped with a Leakage Current Detection Interrupt
(LCDI) device for added safety.
