Operating Instructions

Airflow Direction Control
• Adjust the air flow direction properly. Failure to do so
may cause discomfort or uneven room temperatures.
• Adjust the horizontal louver using the remote control.
• Adjust the vertical louver manually.
Adjusting vertical air flow (Up/Down)
Perform this function while the unit is in operation. Use
the remote control to adjust the vertical air flow
direction. The horizontal louver can move slightly for
each press or continuously swing up and down
automatically. Please refer to the Remote Control
Operation Manual for details.
Adjusting vertical air flow (Left/Right)
• Move the deflector rod manually to adjust the air flow
in the direction you prefer.
IMPORTANT: Do not put your fingers into the panel
of the blower and suction side. The high-speed fan
inside may cause injury.
• Do not operate the air conditioner for long periods
with the air flow direction set downward in cooling or
dehumidifying mode. Doing so may cause
condensation to occur on the surface of the horizontal
louver, resulting in moisture dropping onto the floor
and/or furnishings.
• After a quick restart, the horizontal louver may remain
static for approximately 10 seconds.
• Open angle of the horizontal louver should not be set
too small as Cooling or Heating performance may be
reduced due to an air flow area that is too restricted.
• Do not move the horizontal louver manually. Doing so
will result in the horizontal louver being out of sync.
Should this happen, please cease operating the unit,
power down the unit for a few seconds, then power
the unit back up to restart the air conditioner.

Basic Operation Modes:
AUTO / COOL / DRY / HEAT*
(*Model dependent)
AUTO operation
• When you set the air conditioner in AUTO
mode, it will automatically select cooling,
heating (models with heating function only), or
fan only operation depending on set
temperature and the room temperature.
• The air conditioner will control room
temperature automatically to the temperature
point you set.
• If you feel uncomfortable in the AUTO mode,
you can set your desired temperature at any
time in any mode.
SLEEP operation
• When selected, the set temperature will
increase (cooling) or decrease (models with
heating function only) by 2ºF (1ºC) per hour for
the first 2 hours. Thereafter, the new
temperature will be maintained for 5 hours
before switching off.
• This operation saves energy and improves
night-time comfort by synchronizing with the
body’s metabolism.
DRYING operation
• The temperature is regulated while
dehumidifying by cycling on and off of the
cooling operation or fan only. The fan speed in
DRYING mode is LOW.
HEATING operation - units with Heat Pump
• The air conditioning units with heat pump
operate on the heat pump principle, absorbing
heat from air outdoors and transferring that heat
to the indoor unit. As a result, the operating
performance is reduced as outdoor air
temperature drops. If you feel that the heating
performance is insufficient, we recommend that
you use this air conditioner in conjunction with
other kinds of heating appliances.
Optimal operation
To achieve optimal performance, please note the
following:
• Adjust the air flow direction correctly so that it is
not directly blowing toward people.
• Adjust the temperature to achieve moderate
comfort levels. Excessively low or high
temperature settings waste energy.
• Improve performance by keeping windows and
doors closed.
• Limit energy usage (run time) by using the timer
function.
• Do not put any object near air inlet or air outlet
as the efficiency of the air conditioner may be
reduced and may cause the air conditioner to
stop running.
• Inspect the air filters periodically and clean them
when needed.

Special Functions
Refrigerant Leakage Detection
When refrigerant leakage is detected, the indoor
unit will display “EC” code or flash LEDs
(depending on model).
Louver Angle Memory Function
The minimum and maximum angle of the
horizontal louver is fixed. The unit has a memory
function and will return to the last position
selected. Never adjust the horizontal louver
angle manually. The louver angle memory
function does not apply when TURBO function
or manual control is selected.
Additionally, it is strongly suggested that the
opening of the horizontal louver not be set too
small in case condensation forms and drops
from the horizontal louver.
Auto-restart Function
In the event of a power interruption such as a
blackout, once power is restored, the unit will
restart automatically with all the previous
settings preserved by the memory function.
Self Clean Function
• Airborne bacteria uses the moisture on the
indoor heat exchanger to grow. Regular drying
of the exchanger prevents this growth. By simply
pressing the SELF CLEAN button, the system
will automatically manage the process. This
cleaning action may be done as frequently as
desired.
• For cooling models, only the indoor fan is active
in low speed for 30 minutes and the unit turns off
automatically once self clean session is
complete.
• For cooling and heating models, the unit will
operate in the following sequence:
Fan mode at Low fan speed Heating
operation with Low fan speed Fan operation
Stop operation Turn Off.
NOTE:
• This function can only be activated in COOLING
or DRY mode.
• It is recommended that the air conditioner be run
in the cooling operation for approximately 30
minutes before activating SELF CLEAN function.
• Pressing the SELF CLEAN or ON/OFF button
again during the cleaning cycle will cancel the
operation and turn the unit off.
Mute Operation
Pressing the LED button on the remote control
can turn off the indoor screen display and also
turn of the Air Conditioner buzzer to create a
quieter environment.

CAUTIONS
Cleaning the Unit
Wipe the unit with a soft, dry cloth only. If the unit is
very dirty, wipe it with a cloth soaked in warm water.
Cleaning the Air Filter
A clogged air filter reduces the cooling efficiency of this
unit. Please clean the filter once every 2 weeks:
1. Open the front panel by carefully lifting both ends at
the same time. At a certain angle, a clicking sound is
heard and it becomes self-supporting. For some
models, please use the suspension bars to prop up
the panel.
2. Use the tab provided to move the filter first up a little,
then slightly towards you. Now extract the filter by
gently drawing it downwards.
3. Clean the large air filter with soapy water. Rinse with
fresh water. Shake off excess water and let it dry
COMPLETELY in a cool, dry place.

• Do not touch the metal parts of the unit when
removing the filter. Injuries can occur when
handling sharp metal edges.
• Do not use water to clean inside the air
conditioner. Exposure to water can destroy the
insulation, leading to possible electric shock.
• When cleaning the unit, first make sure that the
power and circuit breaker are turned off.
• Do not wash air filter with hot water at a
temperature greater than 104ºF (40ºC). Shake off
moisture and allow it to dry completely. Do not
expose the filter to direct sunlight. Doing so may
result in shrinking of the filter.
