Digital Inverter Air Conditioner
"1 : 1 Model" Connection Interface
• Before installation work, please read this manual thoroughly and install the products correctly.
• Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Perform installation work surely based on this Installation Manual.
Incomplete installation causes an electric shock or a fire.
• Ask an authorized dealer or qualified installation professional to reinstall 1 : 1 Model Connection
Interface.
Incomplete installation causes an electric shock or a fire.
• For an electric work, this Installation Manual shall be referred and exclusive circuit shall be
necessarily used. The used voltage shall be also match with the rated voltage of the product.
If there is capacity shortage of electric circuit or installation work is poor, an electric shock or a fire may be
caused.
• Using the specified wires, surely connect wires so that external force of wire is not applied to connecting
part of the terminals; otherwise disconnection, heating or fire will generate.
• For wiring work, use wires with correct current capacity; otherwise leakage, heating or fire will generate.
• Do not apply an excessive force on the board body, otherwise bending, separation, or disconnection gener-
ates resulted in heating or fire.
• After installation work, execute a test run to confirm there is no trouble.
And also ask the customers to keep this Manual by themselves.

Usage • Refer to Owner’s Manual for the central control devices (TCB-SC642TLE2, TCB-CC163TLE2 etc.) Other Cautions • In a group operation, be sure to turn on power supplies of all the indoor units in group control. (Within 3 min- utes) When power supply of the Header unit is not turned on, there is a possibility that the Header unit exchanges with Follower unit. - Page 17 Manual Setup/Change of Line Address in Indoor Unit [In case of 29 refrigerant lines or less (Includes No. of refrigerant lines at Multi side if mixed)] After the system power supply has been turned on, all the line addresses are allocated to “1” by automatic address setup except group control.
