WARNING
Perform electrical work by an authorized service personnel in accordance with this manual and the electrical wiring regulations or implementation regulations of the country. Also do not install this product by yourself. Improper electric work will cause electric shock or a fi re.
Perform installation work in accordance with this manual. Request an authorized service personnel to perform installation work. Do not install this product by yourself. Improper installation will cause injury, electric shock, fi re, etc.
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical breaker, and consult authorized service personnel.
Do not install the unit in the following areas:
▪ Do not install the unit near a source of heat, steam or fl ammable gas. ▪ Area fi lled with mineral oil or containing a large amount of splashed oil
or steam, such as a kitchen. It will deteriorate plastic parts, causing the parts to fail or the unit to leak water.
▪ Area that generates substances that adversely affect the equipment,
such as sulfuric gas, chlorine gas, acid or alkali. It will cause the copper pipes and brazed joints to corrode, which can cause refrigerant leak­age.
▪ Area containing equipment that generates electromagnetic interfer-
ence. It will cause the control system to malfunction, preventing the unit from operating normally.
▪ Area that can cause combustible gas to leak, contains suspended
carbon fi bers or fl ammable dust, or volatile infl ammables such as paint thinner or gasoline. If gas leaks and settles around the unit, it can cause a fi re.
▪ Install the unit in a well-ventilated place avoiding rains and direct sun-
light.
Do not operate this product when your hands are wet. Touching the unit with wet hands will cause an electric shock.
If children may approach the unit, take preventive measures so that they cannot reach the unit.

5. WIRING
WARNING
Before starting installation work, turn off the power of this product and the connection destination. Do not turn on the power again until installa­tion is completed. Otherwise, it will cause electric shock or fi re.
Use the accessories or specifi ed connection cable. Do not modify power supply cable and connection cables other than those specifi ed, do not use extension cables, and do not use independent branch wiring. It may cause electric shock or fi re.
Install the connection cables securely to the terminal block. Confi rm that external force of the cable is not applied to the terminal block. Use the specifi ed cables. If intermediate connection or insertion fi xing are imper- fect, it will cause electric shock, fi re, etc.
When connecting the connection cable, route the cables so that the cover of this product is securely fi xed. If the cover is imperfectly fi xed, it may cause fi re or overheating of the terminals.
Perform earth (ground) work positively. Do not connect the earth (ground) cable to a telephone cable, water pipe, or conductor rod.
Perform all wiring works so that the user does not touch the wiring. Otherwise it will cause injury or electric shock.
If any cable is damaged, do not repair or modify it yourself. Improper work will cause electric shock or fi re.
CAUTION
Do not bind the remote controller cable and the external input cable together with or parallel to the power supply cable of the indoor and outdoor units. It may cause erroneous operation.
When performing wiring work, be careful not to damage the cable or injure yourself. Also, connect the connectors securely. Loose connectors will cause trouble, heating, fi re, or electric shock.
Install the indoor unit, outdoor unit, power supply cable, transmission cable and remote control cable at least 40 in (1 m) away from a television or radio. The purpose of this is to prevent TV reception interference or radio noise. (Even if they are installed more than 40 in (1 m) apart, you could still receive noise under some signal conditions.)
Perform wiring so that water does not enter this product along the exter­nal wiring. Always install a trap to the wiring or take other countermea­sures. Otherwise it will cause trouble or electric shock or fi re.
Confi rm the name of each unit and name of each terminal block of the unit and connect the wiring in accordance with the directions given in the manual so that there is no incorrect wiring. Incorrect wiring will damage the electric parts and cause smoke and fi re.
When installing the connection cables near a source of electromagnetic waves, use shielded cable. Otherwise, a breakdown or malfunction could result.
The terminal screws and earth (ground) screws have different shapes. Be sure to install the screws in the correct locations. If the screws are installed in the wrong locations, the circuit board could be damaged.
