• Be sure to keep this manual after reading.
• The manufacturer is not liable for maintenance and repair of the air conditioner as stipulated in the warranty. The
same condition applies to any damage to this unit body/nearby property if you fail to observe warning instructions in
this manual/use of parts not supplied from us.
• This product uses non-flammable R410A refrigerant. While the product is under installation or transport, except R410A
refrigerant, please do not charge other refrigerants, air, oxygen, propane, alcohol, or any flammable material to avoid
machine damage, blaze, or explosion. Be sure to use the refrigerant specified by the manufacturer.
INSTALLATION PRECAUTIONS
• Air conditioner installation and its electrical wiring require a professional. Therefore, assign
only an authorized dealer or a certified technician to install your air conditioner and perform
W
its electrical wiring. Do not attempt to do it by yourself (charges are additional). If improperly
A
performed by yourself, it may cause leakage, electric shock or fire.
R
• Do not use a metal wire or copper wire as a fuse to prevent from failure or fire.
N
• When installing, do not use an extended power cord or a power cord with excess bending
I
(radius less than 20mm). Also, use the cable tie supplied with the base-pan to secure it. Do not place the
N
cord inside the unit body or it may cause short circuit or abnormal heat leading to a fire due to insulation
G
damage by an overly compressed cord.
• Use only on single outlet circuit exclusive for the air conditioner.
• Ensure the mounting support is firm and steady or there is a risk the unit may fall.
• To avoid electric shock in case of current leakage, be sure to connect the air conditioner to the
ground. The ground wire diameter should be 2.5 mm² to 6 mm². Also, the end of the ground wire
must be crimped with a round terminal before securing it and must not be loose by accident.
Do not connect the ground wire to the gas pipe, water pipe, lightning rod, and the telephone line.
If the ground wire is not installed properly, there is a risk of electric shock. If the unit is not grounded,
the protective circuit such as lightning striking protection will not work properly.
• To avoid carelessness from power companies or other accidents that cause over current to get into the unit via
the ground wire resulting in damage to the unit, be sure to install an earth leakage circuit breaker. Consult the
dealers (a registered water and electrical engineering dealer) for details. If no earth leakage circuit breaker is
installed, there is a risk of accident such as electric shock to occur.
•
e When installing near places with high humidity such as bathing facilities, damp and humid places, basements,
and places with frequent water accumulation, be sure to install an earth leakage circuit breaker to prevent
current leakage. Consult the dealers (a registered water and electrical engineering dealer) for details.
• Do not install at places where flammable objects and flammable gases exist.

• Do not allow ejected heated air to face your neighbors. Also, do not let water dripping, drainage, vibration,
noise, etc. interfere your neighbors.
• This unit is intended to be used for general family room air conditioning purpose, do not use it for storing food,
animals and plants, precision machinery, fine art works, medicine, etc.
• When installing the water drain hose, be sure water can flow out smoothly. If installation is not proper, it is
possible that water may flow inside the room or get your furniture wet.
• Plug the power cord to the right source, and the voltage required by the air conditioner is 230V.
• If the power of the air conditioner is connected to an incorrect voltage, it will invariably burn out the electrical
parts.
• Be sure to firmly plug the power supply cord or it may cause short circuit or heat resulting in danger of fire or
electric shock.
• Periodically check the power cord plug and receptacle every year to ensure that they are clean.
•
While indoor unit front cover is not installed, do not operate the unit. Moreover, be sure to take good measures
against dust and dirt for unit body.
• Before the unit starts, be sure to check that the room has been cleaned up, airborne matters and odors have
been cleared, the unit body is clean. This will prevent insufficient cooling or water leakage in later days.

• If there is a heat source (many people come in and out, a heating appliance is being used, etc.) that exceeds the
capacity of cooling or heating, the room temperature may not reach the desired setting level.
• If there is any abnormal noise is heard during unit operation, refer to the service center or to the dealer from
where the air conditioner was purchased.
• When installing at areas subjected to high salinity, sulfur, corrosive substance such as coastal areas and
hot springs, the heat exchanger of the unit or the circulation piping must be treated with anti-corrosion
coating. In addition, installation at places subjected to plenty of fumes, at hospitals where electromagnetic
wave is available, at places subject to dust and dirt or special environmental situations around installation,
consult the service center or the dealer from where the air conditioner was purchased first.
