Be sure to use only wire specified for the use of air-
conditioner.
Please refer to the manual for wire connection and the
wiring technique should meet the standard of the electrical
installation.
There is an AC voltage drop between the LN terminal if the
power is on. Therefore, be sure to remove the plug from its
socket.
WARNING
Leave some space in the connecting
cord for maintenance purpose and be
