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 and electrical engineering dealer) for details.
Do not install at places where flammable objects and flammable gases exist.
If such objects and gases are around, a fire may occur.
The outdoor side should be well ventilated. Do not place any obstacle near the air discharge outlet, otherwise,
the unit performance may decrease and the noise increases.
Do not place any object in front of the indoor side, otherwise, it may affect airflow and Impede operation of the
unit.
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.
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 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.
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.

When installing, do not use an extended power cord or a power cord with excess bending (radius less than
20mm). Also, use the cable tie supplied with the base-pan to secure it. Do not place the cord inside the unit
body or it may cause short circuit or abnormal heat leading to a fire due to insulation damage by an overly
compressed cord.
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 wiring. Do not attempt to do it by yourself (charges are additional). If improperly
performed by yourself, it may cause leakage, electric shock or fire.
