4.  ELECTRICAL WIRING
4-1. General Precautions on Wiring 
(1)  Before wiring, confirm the rated voltage of the unit as 
shown on its nameplate, then carry out the wiring closely 
following the wiring diagram.
(2)  Provide a power outlet to be used exclusively for each 
unit, and a power supply disconnect and circuit breaker for 
overcurrent protection should be provided in the exclusive 
line.
(3)  To prevent possible hazards from insulation failure, the unit 
must be grounded.
(4)  Each wiring connection must be done in accordance with 
the wiring system diagram. Wrong wiring may cause the 
unit to misoperate or become damaged.
(5) Donotallowwiringtotouchtherefrigeranttubing,
compressor, or any moving parts of the fan.
(6)  Unauthorized changes in the internal wiring can be very 
dangerous. The manufacturer will accept no responsibility 
for any damage or misoperation that occurs as a result of 
such unauthorized changes.
(7)  Regulations on wire diameters differ from locality to 
locality. For field wiring rules, please refer to your LOCAL 
ELECTRICALCODESbeforebeginning. 
You must ensure that installation complies with all relevant 
rules and regulations.
(8)  To prevent malfunction of the air conditioner caused by 
electrical noise, care must be taken when wiring as follows:
●  The remote control wiring and the inter-unit control wiring 
should be wired apart from the inter-unit power wiring.
●  Use shielded wires for inter-unit control wiring between units 
and ground the shield on both sides.
(9)  If the power supply cord of this appliance is damaged, 
it must be replaced by a repair shop appointed by the 
manufacturer, because special-purpose tools are required.
