– Investigate the power supply capacity and other
electrical conditions at the installation location.
– Depending on the model of room air conditioner to be
installed, requiest the customer to make arrangements
for the necessary electrical work etc
– The electrical work includes the wiring work up to the
outlet. In localities where electrical conditions are poor,
use of a voltage regulation is recommended
