English

Outside the air conditioners, separate the low voltage wiring 

 

(remote controller and transmission wiring) and high voltage 
wiring (ground wire and power supply wiring) by at least 5 in. 
so that they do not pass through the same place together. 
Proximity may cause electrical interference, malfunctions, 
and breakage.

[ PRECAUTIONS ]

Refer to the “REMOTE CONTROLLER INSTALLATION 

• 

MANUAL” on how to install and lay the wiring for the remote 
controller.
See also the “Wiring Diagram Label” located inside the unit’s 

• 

fan housing.
Connect the remote controller and transmission wiring their 

• 

respective terminal blocks.

 CAUTION

Do not, under any circumstances, connect the power supply 

 

wiring to the remote controller or transmission wiring termi-
nal block. Doing so can destroy the entire system.
