Grounding work
<< CAUTION >>
•
Don't fail to perform installation of Grounding work. Don't connect the grounding wire to any of gas pipe,
city water pipe, lightning rod, and telephone grounding wire.
Don't turn ON the power supply (front switch) until all the works are complete.
The connecting wiring for communication of indoor and outdoor units is a connecting wiring for the control.
Don't clamp these cables together with high voltage cables.
Failure to observe this instruction would cause control error.
Don't connect the power cable to F1, F2 terminal blocks. Wrong connection to these terminal blocks could
result in damage and burning of the centralized control devices and of the electric parts of the indoor and outdoor units.
This is very hazardous. Check each wired cable once more before turning ON the power switch.
