NOTE:
1. Optimum performance is achieved within these operating temperatures If the air
conditioner is used outside of the above conditions, certain safety protection features
might come into operation and cause the unit to function abnormally.
2. If the air conditioner operates in a room whose relative humidity is less than 80%
the surface of the air conditioner may attract condensation. Please set the vertical
airflow louver to its maximum angle (vertically to the floor), and set to the HIGH fan mode.
32°F~122°F
(0°C~50°C)
Suggestion: Because the unit uses an electric heater when the outside ambient temperature
is below 32°F(0 °C), we strongly recommend that you keep the machine plugged in to
help the unit run smoothly.

Vertical
louver
•Adjust the air flow direction properly otherwise it
might cause discomfort or cause uneven room
temperatures.
•Adjust the horizontal/vertical louver using the remote
controller. For some models, the vertical louver can
only be adjusted manually.
To set the horizontal/vertical air flow direction
• Perform this function while the unit is in operation.
• Use the remote controller to adjust the air flow direction.
The vertical/horizontal louver adjusts 6 degrees in angle
for each press.
Please refer to the "REMOTE CONTROLLER OPERATION
MANUAl" for details.
• For some models, the vertical louver can only be adjusted
manually. 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
blower and suction side .The high-speed fan may
cause injury.
Range
CAUTION
• Do not operate the air conditioner for long periods with
the air flow direction set downward in the cooling or
dehumidifying mode. Otherwise, condensation may
accumulate on the surface of the horizontal louver
causing moisture to drop on to the floor or on furnishings.
• Do not move the horizontal louver manually unless it is
necessary. Always use the remote controller.
• When the air conditioner is started immediately after it
was stopped, the horizontal louver might not move for
approximately 10 seconds.
• Open angle of the horizontal louver should not be set
too low as COOLING or HEATING performance may
be impaired due to a highly restricted air flow area
• Do not operate unit with the horizontal louver in
theclosed position.
• When the air conditioner is connected to power (initial
power), the horizontal louver may generate a sound for
10 seconds, this is a normal.

• The set temperature should be stable within two hours.
And the air conditioner will turn off in 7 hours.
• The fan speed will be automatically controlled.
• This feature can maintain the most comfortable
temperature and reduce energy costs.
DRYING operation
• The fan speed will be automatically controlled
under the dry operation.
• During the the dry operatio0 if the room temperature
is lower than 50°F(10°C), the compressor stops
operating and restarts until the room temperature
is above 54°F(12°C).

Operation mode selection
While simultaneously operating two indoor units or more, make sure the operation modes will
not conflict with each other. The heat mode claims precedence over all other modes. If the unit
intially started operates under the heat mode, the other units may only operate under heat mode.
For example: If the unit intially started operates under cool(or fan) mode, the other units can
operate under any mode except heat. If one of the units select heat mode, the other operating
units will stop operation and display" --" (For the units with the display window only) or the Auto and
Operation indication light will flash rapidly, the Defrost indication light turns off, the Timer indication
light remains on(for the units without a display window), or the Defrost and Alarm indication light(
if applicable) illuminate, the Operation indication light flashes rapidly and the Timer indication
light turns off ( for the floor and standing type).
Optimal operation
To achieve optimal performance, please note the following:
•Adjust the air flow direction correctly so that it is not directed toward people.
• Adjust the temperature to achieve the highest comfort level. Do not adjust the unit to excessive
temperature levels.
• Close doors and windows when the unit is operating on COOL or HEAT modes,
or the performance may be reduced.
• Use the TIMER ON button on the remote controller to select a time you want to start your air conditioner.
• Do not put any object near the air inlet or air outlet, as the efficiency of the air conditioner may be reduced
and the air conditioner may stop running.
• Clean the air filter periodically, otherwise cooling or heating performance may be reduced.
• Do not operate unit with horizontal louvre in the closed position.
Suggestion: Because the unit uses an electric heater, when the outside ambient temperature is
below 32°F(0°C),we strongly recommend that you keep the machine plugged in to
help the unit run smoothly.

Care and maintenance
Filter Handle
Cleaning the Grille, Case and Remote Controller
•Turn the system off before cleaning. To clean, wipe
with a soft, dry cloth. Do not use bleach or abrasives.
NOTE: Supply power must be disconnectd before
cleaning the indoor unit.
• A cloth dampened with cold water may be used on
the indoor unit if it is very dirty. Then wipe it with a
dry cloth.
• Do not use a chemically treated cloth or duster to
clean the unit.
• Do not use benzine, thinner, polishing powder, or
similar solvents for cleaning. These may cause
the plastic surface to crack or deform.
• Never use water hotter than 104 °F(40 °C) to clean
the front panel, it could cause deformation of
discoloration.
• WALL-MOUNTED TYPE
Cleaning the air filter
A clogged air filter reduces the cooling efficiency of
this unit. Please clean the filter once every 2 weeks.
1. Lift the indoor unit panel up to an angle until it
stops with a clicking sound.
2. Take hold of the handle of the air filter and lift it
up slightly to take it out from the filter holder,
then pull it downwards.
3. Remove the Active Carbon & Dust Filter from the
indoor unit.
•Clean the filter once every two weeks.
• Clean the filter with a vacuum cleaner or water,
then dry it up in cool place.

CARE AND MAINTENANCE
4. Remove the Air Freshening Filter(Optional filter:
Plasma Dust collector/Silver Ion filter/Bio filter
Vitamin C filter) from its support frame.
(The installation and removing method of the air
freshening filter is different depending on the models,
(see the images marked Q and @ on the left).
• Clean the air freshening filter at least once a month,
and replace it every 4-5 months.
• Clean it with a vacuum cleaner, then dry it in cool place.
5. Install the air freshening filter back into position.
6. Insert the upper portion of air filter back into the unit
taking care that the left and right edges line up
correctly and place the filter into position.
Maintenance
If you plan to idle the unit for a long time, perform the
following:
(1) Operate the fan for about half a day to dry the
inside of the unit.
(2) Stop the air conditioner and disconnect the power.
Remove the batteries from the remote controller.
(3) The outdoor unit requires periodic maintenance
and cleaning. Do not attempt this yourself.
Contact your dealer or servicer.
Checks betore operat ion
• Check that the wiring is not broken or
disconnected.
• Check that the air filter is installed.
• Check if the air outlet or inlet is blocked after the
air conditioner has not been used for a long time.
,,_, Caution )
• Do not touch the metal parts of the unitwhen
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.
