Press to set the fan speed to Low (Bajo) (F1),
Medium (Medio) (F2) or High (Alto) (F3).
3Delay ON/OFF Timer
Delay ON - When the air conditioner is off,
set it to automatically turn on from 1 to 24
hours later, at its previous mode and fan
settings.
Delay OFF - When the air conditioner is on,
set it to automatically turn off from 1 to 24
hours later.
NOTE
●Each press of the Timer (Control Tiempo ) ,
button advances the timer by 1 hour. After
the last press the display returns to the
temperature setting.
4Operation Mode
Press the Mode (Modo) button to cycle
between 4 types of air conditioner operation:
Energy Saver (Ahorro Energía) / Cool (Frío) /
Fan (Vent.) / Dry (Deshum).
Cool (Frío)
Fan (Vent.) - In this mode the fan circulates
air but the compressor does not run. Use
the Fan Speed (Nivel Vent.) button to set
speed to High, Medium or Low. In this mode,
you cannot adjust the set temperature.
Dry (Deshum) - This mode is ideal for rainy
and damp days to dehumidify the room rather
than cooling it significantly. Humidity is
removed from the room by the combination
of compressor operation and the fan speed
fixed at Low. The compressor and fan turn
off once the set temperature is reached.
Fan speed cannot be adjusted in Dry (Deshum)
mode.

- This mode is ideal on hot days
to cool and dehumidify the room quickly. Use
the Temp buttons to set the desired

button to set the desired fan
circulation speed.
Energy Saver (Ahorro Energía) - In this
the compressor and fan turn off when the
set temperature is achieved. Approximately
every 3 minutes the fan turns on to allow
the unit sensor to accurately determine if
more cooling is needed.

12 OPERATION

Slinger Fan
This air conditioner is equipped with a slinger
fan. (See drawing.)
The fan’s outer ring picks up the condensed
water from the base pan if the water level gets
high enough. The water is then picked up by the
fan and expelled through the condenser, making
the air conditioner more efficient.

Air Direction

air deflector control.
Using the control tabs, the air flow can be
directed to the left, right, straight ahead, or any
combination of these directions.

MAINTENANCE
WARNING
Before cleaning or performing maintenance,
disconnect the power supply and wait until
the fan stops.
Air Filter
Check the air filter at least twice a month to see
if cleaning is necessary. Trapped particles in the
filter can build up and block the airflow, reducing
cooling capacity and causing an accumulation of
frost on the evaporator.
Cleaning the Air Filter
Cleaning the Air Conditioner
●Wipe the front grille and inlet grille with a cloth
dampened in a mild detergent solution.
●Wash the cabinet with mild soap or detergent
and lukewarm water, then polish using liquid
appliance wax.

TROUBLESHOOTING
Before Calling for Service
The appliance is equipped with an automatic error-monitoring system to detect and diagnose problems
at an early stage. If the appliance does not function properly or does not function at all, check the
following before you call for service.
Normal Sounds You May Hear
1High Pitched Chatter
2Sound of Rushing Air
At the front of the unit, you may hear the sound of rushing air being moved by the fan.
Today’s high efficiency compressors may have a high pitched chatter during the cooling cycle.
3Gurgle/Hiss
Gurgling or hissing noise may be heard due to refrigerant passing through evaporator during
normal operation.
4Vibration
Unit may vibrate and make noise because of poor wall or window construction or incorrect
installation.
5Pinging or Swishing
Droplets of water hitting condenser during normal operation may cause pinging or swishing
sounds.
