PRECAUTIONS DURING INSTALLATION
WARNING
Do not reconstruct the unit.
Water leakage, fault, short circuit or fire may occur if you reconstruct the unit by
yourself.
PROHIBITION
• Please ask your sales agent or qualified technician for the installation of your unit.
Water leakage, short circuit or fire may occur if you install the unit by yourself.
Please use earth line.
Do not place the earth line near water or gas pipes, lightning-conductor, or the
earth line of telephone. Improper installation of earth line may cause electric
shock or fire.
CONNECT EARTH LINE
Be sure to use the specified piping set for R410A. Otherwise, this may result in
broken copper pipes or faults.
CAUTION
A circuit breaker should be installed depending on the mounting site of the unit.
Without a circuit breaker, the danger of electric shock exists.
PROHIBITION
Do not install the unit near a location where there is flammable gas.
The outdoor unit may catch fire if flammable gas leaks around it.
Please ensure smooth flow of water when installing the drain hose.
Make sure that a single phase 220V-230V power source is used.
The use of other power sources may cause electrical components to overheat
and lead to fire.
PROHIBITION
PRECAUTIONS DURING SHIFTING OR MAINTENANCE
WARNING
Should abnormal situation arise (like burning smell), please stop operating the
unit and turn off the circuit breaker. Contact your agent. Fault, short circuit or fire
may occur if you continue to operate the unit under abnormal situation.
Please contact your agent for maintenance. Improper self maintenance may cause electric shock
and fire.
Please contact your agent if you need to remove and reinstall the unit. Electric shock or fire may
occur if you remove and reinstall the unit yourself improperly.

for a long period of time, water will condense on the air deflector and drips down
occasionally. This will wet your furniture. Therefore, do not operate under such
condition for a long time.
PROHIBITION
PROHIBITION
If the amount of heat in the room is above the cooling or heating capability of
the unit (for example: more people entering the room, using heating equipments
and etc.), the preset room temperature cannot be achieved.
Indoor unit cleaning must be performed by authorized personnel only. Consult
your sales agent.
Using a commercially available detergent or similar can damage the plastic parts

PREPARATION BEFORE OPERATION
To install the batteries
To x the remote controller holder to the wall
1. Slide the cover to take it off.
2. Install two dry batteries AAA.LR03 (alkaline).
The direction of the batteries should match the
marks in the case.
3. Replace the cover at its original position.
1. Choose a place from where the signals can reach the unit.
2. Fix the remote controller holder to a wall, a pillar or similar
location with the provided screws.
3. Place the remote controller in the remote controller holder.
NOTE
Notes on batteries
When replacing the batteries, use batteries of the same
type, and replace both old batteries together.
When the system is not used for a long time, take the
batteries out.
The batteries will last for approximately 1 year. However, if
the remote controller display begins to fade and degradation
of reception performance occurs within a year, replace both
batteries with new size AAA.LR03 (alkaline).
The attached batteries are provided for the initial use of
the system.
The usable period of the batteries may be short depending
on the manufactured date of the air conditioner.
Notes on the remote controller
Never expose the remote controller to direct sunlight.
Dust on the signal transmitter or receiver will reduce the
sensitivity. Wipe off dust with soft cloth.
Signal communication may be disabled if an electronic-
starter-type fluorescent lamp (such as inverter-type lamps)
is in the room. Consult the shop if that is the case.
If the remote controller signals happen to operate another
appliance, move that appliance to somewhere else, or
consult the service shop.
When the remote controller is not in use, please close the
slide cover to prevent failure.

FILTER CLEANING OPERATION (AUTOMATIC OPERATION)
To stop AUTOMATIC FILTER CLEANING operation
Automatic filter cleaning mode is set at the time of purchase.
Automatically cleans the micro mesh stainless filter when the basic air-conditioning operation (AUTO,
HEATING, DEHUMIDIFYING or COOLING) has ended.
• The cleaning unit makes cycle to back and forth movement to sweep the dust on the micro mesh
stainless filter and the dust catcher puts the collected dust into the dust box.
One cycle of filter cleaning operation will take approximately 5 minutes.
Conditions of the automatic filter cleaning.
When the air conditioner operates for more than 15 minutes and stops, automatic filter cleaning is
performed in one of the following conditions.
(1) Accumulated operating hours of the air conditioner have exceeded 8 hours.
(2) Air conditioner is not operated for more than one week.

filter cleaning operation is performed.
After the completion of automatic filter cleaning, the operation will return to previous mode.
Automatic filter cleaning is not performed if the air conditioner operation is stopped by sleep timer or
off timer function.
If you use sleep timer or off timer every time, it is recommended to operate manual filter cleaning once
every 2~3 days.
