NOTE
Pay special attention to the electric wiring to prevent that the air conditioner goes out of control owing to the 
electromagnetic interference.
① 
The signal line and communication line should be separated with the power cord and the connecting wires 
between indoor  and outdoor units  should be with a minimal distance of 20cm, otherwise the communication 
would go wrong.
② 
If the air conditioner is installed where it would be affected by electromagnetic interference, the signal line 
and the communication line must be the shielded twisted pairs.
