near the terminal board.
3.3 Checking for the electric source and
the voltage range
●
Before installation, the power source must be
checked and necessary wiring work must be
completed. To make the wiring capacity proper,
use the wire gauges list below for the lead-in
from a pole transformer and for the wiring from a
switch board of fuse box to the main switch and
outdoor unit in consideration of the locked rotor
current.
●
Investigate the power supply capacity and other
electrical conditions at the installation location.
Depending on the model of room air conditioner
to be installed, request the customer to make
arrangements for the necessary electrical work etc.
The electrical work includes the wiring work up
the outlet. In localities where electrical conditions
