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 flammable gas.
Area filled 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 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 interference. 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 fibers or flammable dust, or volatile inflammables such as paint thinner or gasoline.
If gas leaks and settles around the unit, it can cause a fire.
Install the unit in a well-ventilated place avoiding rains and direct sunlight. Do not touch the remote controller PC board and PC board parts directly with your hands.
Do not wire the remote controller cable and the bus wire together with or parallel to the connection cables, transmission cables, and power supply cables of the indoor and outdoor units.
It may cause erroneous operation. When installing the bus wire near a source of electromagnetic waves, use shielded wire.
Do not set the DIP switches, either on the air conditioner or the remote controller, in any way other than indicated in this manual or the manual that is supplied with the air conditioner.
Doing so may result in an improper operation. 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. Doing so will cause heating, fire, or electric shock. Dispose of the packing materials safely.

INSTALLING THE REMOTE CONTROLLER

Wiring

Before starting installation work, turn off the power of the connection destination.
Do not turn on the power again until installation is completed.
Otherwise, it will cause electric shock or fire.
Use the accessories or specified connection cables.
Do not modify connection cables other than those specified, do not use extension cords, and do not use independent branch wiring.
The allowable current will be exceeded and cause electric shock or fire.
Install the connection cables securely to the terminal block.
Confirm that external force is not applied to the wire.
Use connection cables made of the specified wire.
If intermediate connection or insertion fixing are imperfect, it will cause electric shock, fire, etc.
Do not connect functional earthing to a telephone functional earthing, water pipe, or conductor rod.
Always fasten the outside covering of the connection cable with the cable clamp. (If the insulator is chafed, electric leakage may occur.)
When performing cable wiring work, be sure that it does not touch the user. Doing so 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 fire.

Connection of remote controller cable

When connecting to the wall mounted type and the floor type connector

Modify the cable as per below methods.

Use a tool to cut off the terminal on the end of the remote controller cable and then remove the insulation from the cut end of the cable as shown in Fig. 1.
Connect the remote controller cable and connecting cable as shown in Fig. 2.
Be sure to insulate the connection between the cables.
