result in serious consequences if not observed properly. Please observe all instructions strictly to ensure safety.
●
The sign indicate the following meanings.
●
Please keep this manual after reading.
PRECAUTIONS DURING SHIFTING OR MAINTENANCE
●
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 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.
●
If the supply cord is damaged, it must be replaced by the special cord obtainable at authorized
service/parts centers.
Make sure to connect earth line.
Indicates the instructions that must be followed.
The sign in the figure indicates prohibition.

●
Do not insert finger(s), 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.
●
During thunder storm, disconnect and turn off the circuit breaker.
●
Do not use any conductor as fuse wire, this could cause fatal accident.
WARNING
PRECAUTIONS DURING INSTALLATION
●
Do not reconstruct the unit.
Water leakage, fault, short circuit or fire may occur if you reconstruct the unit by yourself.
●
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.
●
A circuit breaker should be installed depending on the mounting site of the unit. Without
a circuit breaker, the danger of electric shock exists.
●
Do not install near 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.
●
Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its
mist flows 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, breake the plastic
parts of the indoor unit.
CAUTION
!
!
●
This unit has UV LED which emits ultra violet light.
AVOID DIRECT EYE EXPOSURE.

PRECAUTIONS DURING OPERATION
●Do not attempt to operate the unit with wet hands, this could cause fatal
accident.
●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.
●Do not place plants directly under the air flow as it is bad for the plants.
●Please ensure that outdoor mounting frame is always stable, firm and
without defect. If not, the outdoor unit may collapse and cause danger.
●Do not splash or direct water to the body of the unit when cleaning it as
this may cause short circuit.
●When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air deflector facing down or moving automatically 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.
●If the amount of heat in the room is above the cooling capability of the unit (for example: more
people entering the room, using heating equipments and etc.), the preset room temperature
cannot be achieved.
●This appliance is not intended for use by young children unless they have been adequately
supervised by a responsible person to ensure that they can use the appliance safely.
●Young children should be supervised to ensure that they do not play with the appliance.
●Do not climb on the outdoor unit or put objects on it.
●Please switch off the unit and turn off the circuit breaker during cleaning,
the high-speed fan inside the unit may cause danger.
●Turn off the circuit breaker if the unit is not to be operated for a long period.

●The product shall be operated under the manufacturer specification and
not for any other intended use.
●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.
●Do not use any aerosol or hair sprays near the indoor unit. This chemical
can adhere on heat exchanger fin and blocked the evaporation water
flow to drain pan. The water will drop on tangential fan and cause water
splashing out from indoor unit.

2Adjustment of the conditioned air to the left and right.
Hold the second vertical air deflector of each set of vertical
air deflectors from right as shown in the figure and adjust the
conditioned air to the left or right.
●If the “ (AUTO SWING)” button is pressed once,
the horizontal air deflector swings up and down. If the
button is pressed again, the deflector stops in its current
position. Several seconds (about 6 seconds) may be
required before the deflector starts to move.
●Use the horizontal air deflector within the adjusting range
shown on the right.
●When the operation is stopped, the horizontal air deflector
moves and stops at the position where the air outlet
closes.

CAUTION
●In “Cooling” operation, do not keep the horizontal air
deflector swinging for a long time. Some dew may form
on the horizontal air deflector and dew may drop.
Adjustment of the conditioned air in the upward and downward
directions.
The horizontal air deflector is automatically set to the proper
angle suitable for each operation. The deflector can be swung
up and down continuously and also set to the desired angle
using the “ (AUTO SWING)” button.

FOR USER’S INFORMATION
The Air Conditioner And The Heat Source In The Room
Not Operating For A Long Time
When Lightning Occurs
Caution
If the amount of heat in the room is above the cooling
capability of the air conditioner (for example: more people
entering the room, using heating equipments and etc.), the
preset room temperature cannot be achieved.
When the indoor unit is not to be used for a long period of
time, please switch off the power from the mains. If the power
from mains remains “ON”, the indoor unit still consumes about
8W in the operation control circuit even if it is in “OFF” mode.
Warning
To protect the whole unit during lightning, please stop
operating the unit and remove the plug from the socket.
Interference From Electrical Products
Caution
To avoid noise interference, please place the indoor
unit and its remote controller at least 1m away from
electrical products.

MAINTENANCE
Cleaning and maintenance must be carried out when filter lamp lights. Before cleaning, stop
operation and switch off the power supply.
1. PRE-FILTER
Clean the Pre-filter, as it removes dust inside the room. In case the Pre-filter is full of dust, the air
flow will decrease and the cooling capacity will be reduced. Further, noise may occur. Be sure to
clean the Pre-filter following the procedure below.
!
CAUTION
1Open the front panel and remove the Pre-filter
●Gently lift and remove the air purifying filters
from the air purifying filter frame.
2Vacuum dust from the Pre-filter and air purifying
filter using vacuum cleaner. If there is too much
dust, rinse Pre-filter under running tap water
and gently brush it with soft bristle brush. Allow
Pre-filter to dry in shade.
3●Re-insert the air purifying filter to the filter
frame. Set the Pre-filter with “FRONT” mark
facing front, and slot them into the original
state.
●After attaching the Pre-filters, push the front
panel at three arrow portions as shown in
figure and close it.
!CAUTION
●Do not wash with hot water at more than 40°C. The Pre-filter may shrink.
●When washing it, shake off moisture completely and dry it in the shade; do not expose it directly
to the sun. The Pre-filter may shrink.
●Do not use detergent on the Pre-filter as some detergent may deteriorate the Pre-filter electrostatic
performance.
●Do not operate the air conditioner without Pre-filter. Dust may enter the air conditioner and fault
may occur.
NOTE:
●Air purifying filter should be cleaned every month or sooner if noticeable loading occurs. When
used overtime, it may loose its deodorizing function. For maximum performance, it is recommended
to replace it every 1 year depending on application requirements.
