
We are not liable for maintenance and repair of your air conditioner as stipulated in the warranty or for any damage of
this unit body or nearby property if you fail to observe warning instructions in this manual or use of parts not supplied
from us.
 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 its electrical
W
wiring. Do not attempt to do it by yourself (charges are additional). If improperly performed by
A
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 (radius less than
I
20mm). Also, use the cable tie supplied with the base-pan to secure it. Do not place the cord inside the unit
N
body or it may cause short circuit or abnormal heat leading to a fire due to insulation damage by an overly
compressed cord.
G
 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 mm
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.
 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
C
and electrical engineering dealer) for details.
A
 Do not install at places where flammable objects and flammable gases exist. If such objects
U
and gases are around, a fire may occur.
T
 The outdoor side should be well ventilated. Do not place any obstacle near the air discharge outlet, otherwise,
I
the unit performance may decrease and the noise increases.
O
 Do not place any object in front of the indoor side, otherwise, it may affect airflow and impede operation of the
unit.
N
 Do not place any foreign material around the unit body, otherwise, it may affect the performance of the unit.
 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 drainhose, 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.
 Be sure the power supply voltage 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 invariable 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 front cover is taking place, do not operate the unit. Moreover, be sure to take good measures
against dust and dirt for the 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.
