 Do not alter the inner wires of air conditioner. Manufacturer does not assume
responsibility for damage or abnormal operation due to this reason.

recommended to use twin-twisted shield wire. During wire connection, please pay
attention that the metal shield layer of the twin-twisted wire must be grounded(outer
case) in order to prevent the unit from electromagnetic interference.
 The communication wires should be separated from power cord and connection wire
between indoor unit and outdoor unit.
 If the project needs higher static pressure, you can set it through the wired controller.
 The appliance must be fitted with means for disconnection from the supply mains having
a contact separation in all poles that provide full disconnection under overvoltage
category III conditions, and these means must be incorporated in the fixed wiring in
accordance with the wiring rules.
