O Do not insert a  nger, a rod or other objects into the air outlet or inlet. As the fan is rotating
at a high speed, it will cause injury. Before cleaning, be sure to stop the operation and turn
the breaker OFF.
O Do not use any conductor as fuse wire, this could cause fatal accident.
PRECAUTIONS DURING SHIFTING OR MAINTENANCE
O Should abnormal situation arises (like burning smell), please stop operating the unit and turn
off the circuit breaker. Contact your agent. Fault, short circuit or  re may occur if you continue
to operate the unit under abnormal situation.
OPlease contact your agent for maintenance. Improper self maintenance may cause electric
shock and  re.
OPlease contact your agent if you need to remove and reinstall the unit. Electric shock or  re
may occur if you remove and reinstall the unit yourself improperly.
OIf the supply cord is damaged, it must be replaced by the special cord obtainable at
authorized service/parts centers.

WARNING
PRECAUTIONS DURING INSTALLATION
O Do not reconstruct the unit.
Water leakage, fault, short circuit or  re may occur if you reconstruct the unit by yourself.
O Please ask your sales agent or quali ed technician for the installation of your unit. Water
leakage, short circuit or  re may occur if you install the unit by yourself.
O 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.
O Be sure to use the speci ed piping set for R410A. Otherwise, this may result in broken
copper pipes or faults.
O A circuit breaker should be installed depending on the mounting site of the unit. Without
a circuit breaker, the danger of electric shock exists.
O Do not install near location where there is  ammable gas. The outdoor unit may catch
re if  ammable gas leaks around it.
O Please ensure smooth  ow of water when installing the drain hose.
O Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its
mist  ows to the indoor unit. The oil will deposit on the heat exchanger, thereby reducing
the indoor unit performance and may deform and in the worst case, break the plastic
parts of the indoor unit.
CAUTION
!
!
O
Spray cans and other combustibles should not be located within a meter of the air outlets
of both indoor and outdoor units.
As a spray can’s internal pressure can be increased by hot air, a rupture may result.
Make sure to connect earth line. The sign in the  gure indicates prohibition.
Indicates the instructions that must be followed.

PRECAUTIONS DURING OPERATION
O Do not attempt to operate the unit with wet hands, this could cause fatal
accident.
O When operating the unit with burning equipments, regularly ventilate the
room to avoid oxygen insuf ciency.
O Do not direct the cool air coming out from the air-conditioner panel to face
household heating apparatus as this may affect the working of apparatus
such as the electric kettle, oven etc.
O Do not use any aerosol or hair sprays near the indoor unit. This chemical
can adhere on heat exchanger  n and blocked the evaporation water  ow
to drain pan. The water will drop on tangential fan and cause water splashing
out from indoor unit.
O Please ensure that outdoor mounting frame is always stable,  rm and
without defect. If not, the outdoor unit may collapse and cause danger.
O Do not splash or direct water to the body of the unit when cleaning it as
this may cause short circuit.
O When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air de ector facing down or moving automatically for a long period of time,
water will condense on the air de ector and drips down occasionally. This will wet your furniture.
Therefore, do not operate under such condition for a long time.
O 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.
O
This appliance is not intended for use by young children or in rm persons unless they have been
adequately supervised by a responsible person to ensure that they can use the appliance safely.
O Young children should be supervised to ensure that they do not play with the appliance.
O Do not climb on the outdoor unit or put objects on it.
O Please switch off the unit and turn off the circuit breaker during cleaning,
the high-speed fan inside the unit may cause danger.
O Turn off the circuit breaker if the unit is not to be operated for a long period.

N
O The product shall be operated under the manufacturer speci cation and
not for any other intended use.
O Do not put water container (like vase) on the indoor unit to avoid water
dripping into the unit. Dripping water will damage the insulator inside the
unit and causes short-circuit.
O Do not place plants directly under the air  ow as it is bad for the plants.

PREPARATION BEFORE OPERATION
Ƶ To install the batteries
Ƶ To fix 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
ƽ When replacing the batteries, use batteries of the same
type, and replace both old batteries together.
ƽ When the system is not used for a long time, take the
batteries out.
ƽ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).
ƽ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
ƽNever expose the remote controller to direct sunlight.
ƽDust on the signal transmitter or receiver will reduce the
sensitivity. Wipe off dust with soft cloth.
ƽSignal communication may be disabled if an electronic-
starter-type uorescent lamp (such as inverter-type lamps)
is in the room. Consult the shop if that is the case.
ƽ If the remote controller signals happen to operate another
appliance, move that appliance to somewhere else, or
consult the service shop.
ƽ When the remote controller is not in use, please close the
slide cover to prevent failure.
