SAFETY PRECAUTION
• Please read the “Safety Precaution” carefully before operating the unit to ensure correct usage of the unit.
• Pay special attention to signs of “
Warning” and “ Caution”. The “Warning” section contains matters
which, if not observed strictly, may cause death or serious injury. The “Caution” section contains matters
which may result in serious consequences if not observed properly. Please observe all instructions strictly to
ensure safety.
• The signs indicate the following meanings. (The following are examples of signs.)
• Please keep this manual after reading.
• 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.
• Be sure to use the specified piping set for R410A. Otherwise, this may result in
broken copper pipes or faults.
• 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 the unit near a location where there is flammable gas. The outdoor unit
may catch fire if flammable gas leaks around it. Piping shall be suitable supported
with a maximum spacing of 1m between the supports.
• Please ensure smooth flow of water when installing the drain hose.
• Make sure that a single phase 230V power source is used.
The use of other power sources may cause electrical components to overheat and
lead to fire.

CAUTION
• Avoid an extended period of direct air flow for your health.
• Should abnormal situation arise (like burning smell), please stop operating the unit
and remove plug from the socket. 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

PRECAUTIONS DURING SHIFTING OR MAINTENANCE
• Do not use any conductor as fuse wire, this could cause fatal accident.
• During thunder storm, disconnect the plug top and turn off the circuit breaker.
• Do not put objects like thin rods into the panel of blower and suction side because
the high-speed fan inside may cause danger.
• 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.

• Do not place plants directly under the air flow as it is bad for the plants.
• 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.
• The product shall be operated under the manufacturer specification and not for any
other intended use.
PRECAUTIONS DURING OPERATION
CAUTION
• Do not attempt to operate the unit with wet hands, this could cause fatal accident.
• When operating the unit with burning equipments, regularly ventilate the
room to avoid oxygen insufficiency.
• 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 wash the unit with water or place a water container such as a vase on the
indoor unit.
Electrical leakage could be present and cause electric shock.
• Be sure to stop the operation by using the remote controller 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 be operated for a long period.
• Do not climb on the outdoor unit or put objects on it.
• 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 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
or clog the drain pipe, causing water to drip with potential electric shock hazard.
• Do not touch the air outlet, bottom surface and aluminum fin of the outdoor
unit.
You may get hurt.
• Do not touch the refrigerant pipe and connecting valve.
