1. SAFETY PRECAUTIONS
• The “SAFETY PRECAUTIONS” indicated in the manual contain important information pertaining to your safety. Be sure to observe them.
• For details of the operation method, refer to the operating manual.
• Request the user to keep the manual on hand for future use, such as for relocating or repairing the unit.
WARNING
This mark indicates procedures which, if improperly performed, might lead to the death or serious injury of the user.
Perform installation work in accordance with the installation manual.
Request an authorized service personnel to perform installation work.
Do not install this unit by yourself. Improper installation will cause injury, electric shock, fi re, etc.
Perform electrical work by an authorized service personnel in accordance with the installation manual and the electrical wiring regulations or implementation regulations of the country. Also do not install this unit by yourself. Improper electric work will cause electric shock or a fi re.
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.
Otherwise, fi re could result.
• 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 fall.
• Area containing equipment that generates electromagnetic interference. It will cause the control system to malfunction, and cause erroneous operation.
• Install the unit in a well-ventilated place avoiding rains and direct sunlight.
Do not operate this unit when your hands are wet. Touching the unit with wet hands will cause an electric shock.
When children can approach the unit or touch the unit, take preventive measures.
Dispose of the packing materials safely. Tear and dispose of the plastic packing bags so that children cannot play with them. There is the danger of suffocation if children play with the original plastic bags.
CAUTION
This mark indicates procedures which, if improperly performed, might possibly result in personal harm to the user, or damage to property.
When detecting the room temperature using the remote controller, please set up the remote controller according to the following conditions.
If the remote controller is not well set, the correct room temperature will not be detected, and thus the abnormal conditions like “not cool” or “not heat” will occur even if the air-conditioner is running normally. :
• A location with an average temperature for the room being air conditioned.
• Not directly exposed to the outlet air from the air conditioner.
• Out of direct sunlight.
• Away from the in fl uence of other heat sources.
Do not touch the switches with sharp objects. Doing so will cause injury, trouble, or electric shock.
Do not expose this unit directly to water. Doing so will cause trouble, electric shock, or heating.
Do not set vessels containing a liquid on this unit. Liquid that spills out will cause overheating, fi re and electric shock.
Do not insert articles into the slit parts of this unit. Doing so will cause trouble, heating, or electric shock.

4.3. Setting the room temperature detection location
CAUTION
As the temperature sensor of remote controller detects the temperature near the wall, when there is a certain difference between the room temperature and the wall temperature, the sensor will not detect the room temperature correctly sometimes. Especially when the outer side of the wall on which the sensor is positioned is exposed to the open air, it is recommended to use the temperature sensor of the indoor unit to detect the room temperature when the indoor and outdoor temperature difference is signi fi cant.
The detection location of the room temperature can be selected from the 2 methods at the right. The temperature sensor of the indoor unit or the remote controller can be used to detect the room temperature.
Choose the detection location that is best for the installation location.

5. INSTALLING THE REMOTE CONTROLLER
WARNING
Always use the accessories and speci fi ed installation work parts. Check the state of the installation parts. Not using the speci fi ed parts will cause units to fall off, water leakage, electric shock, fi re, etc.
Install at a place that can withstand the weight of the unit and install positively so that the unit will not topple or fall.
When installing this unit, make sure that there are no children nearby.
Otherwise, injury or electric shock could result.
Before starting installation work, turn off the power of this unit 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 speci fi ed power supply cable and remote controller cables. Do not modify power supply cable and remote controller cables other than those speci fi ed, do not use extension cords, and do not use independent branch wiring. It will cause electric shock or fi re.
Install the remote controller cables securely to the terminal block. Confi rm that external force is not applied to the cable. Use remote controller cables made of the speci fi ed wire. If intermediate connection or insertion fi xing are imperfect, it will cause electric shock, fi re, etc.
When connecting the remote controller cable, route the cables so that the rear case of this unit is securely fi xed. If the rear case is imperfectly fi xed, it may cause fi re or overheating of the terminals.
Always fasten the cable sheath of the connection cable with the cable tie. If the cable sheath is chafed, electric leakage may occur.
CAUTION
Do not set the DIP switch or rotary switch of this unit except as speci fi ed in this manual or the operating manual supplied with the air conditioner.
Setting the switches other than speci fi ed will cause an accident or trouble.
Use an insulated screwdriver to set the DIP switches.
Before opening the case of this unit, completely discharge static electricity charged on you body. Not doing so will cause trouble.
Do not touch the circuit board and circuit board parts directly with your hands. Otherwise, injury or electric shock could result.
Do not overtighten the screws. It will cause damage of this unit.
Install the remote controller cables 1 m away from television and radio to avoid distorted images and noise.
Con fi rm the name of each terminal block of the unit and connect the wiring in accordance with the directions given in the manual. Improper wiring work will damage the electric parts and cause smoke and fi re.
When installing the connection cable near a source of electromagnetic waves, use shielded cable. Otherwise, a breakdown or malfunction could result.

5.3.2. Connecting the remote controller cable
CAUTION
When connecting a remote controller cable to the remote controller terminal block, please use the speci fi ed torque to tighten screws. If you over-tighten screws, they will break the terminal unit.
Be careful to avoid breaking the cable by over-tightening the cable tie.
Tightening torque
0.8 to 1.2 N•m (8 to 12 kgf•cm)
Fasten the connection cable with the cable tie.
Tighten the cable tie fi rmly so that pulling force does not propagate to the terminal connection even if force of 30 N is applied to the cable.
Select a fl exible cable that can be bound using cable ties from over the cable sheath inside this unit.

5.4. Connecting to the indoor unit
CAUTION
When connecting the remote controller cable to the indoor unit, do not connect it to the outdoor unit or the power terminal block. It may cause a failure.
When switching the DIP switch (SW1) on the indoor unit PC board, be sure to turn off the power supply to the indoor unit. Otherwise, the PC board of the indoor unit may be damaged.
There are 2 methods to connect the remote controller cable to the indoor unit. One is the connection using connecting cable (Included in the indoor unit), and the other is the connection the remote controller cable is connected to the exclusive terminal block of the indoor unit.
(For the details, refer to the installation manual of the indoor unit to be used.)
