Open the air inlet panel.
Remove the service panel.
Remove the wiring clamp.
Connect the connecting wire securely to the terminal block.
1) Connect the connection wire securely to the terminal
block. If the wire is not affixed completely, contact will be
poor, and it is dangerous as the terminal block may heat
up and catch fire.
2) Take care not to confuse the terminal numbers for indoor
and outdoor connections.
Fix the connecting wire by wiring clamp.
Attach the service panel.
Close the air inlet panel.

At completion of the setting, the indoor unit emits a buzzer sound
"pip". (If no reception tone is emitted, start the setting from the
beginning again.)
INSTALLATION TEST CHECK POINTS
After installation
The power supply voltage is correct as the rating.
No gas leaks from the joints of the service valve.
Power cables and crossover wires are securely fixed to the terminal board.
The screw of the service panel is tightened securely.
Test run
Air conditioning operation is normal.
No abnormal noise.
Water drains smoothly.
Protective functions are not working.
The wireless remote control is normal.
Operation of the unit has been explained to the customer. (Three-minutes restart preventive timer)
When the air conditioner is restarted or when changing the operation, the unit will not start operating for
