WARNING
G
To avoid the risk of electric shock, each air
conditioner unit must be grounded.
G
For the installation of a grounding device,
please observe local electrical codes.
G Grounding is necessary, especially for units
using inverter circuits, in order to release
charged electricity and electrical noise
caused by high tension.
Otherwise, electrical shock may occur.
G
Place a dedicated ground more than 2 meters
away from other grounds and do not have it
shared with other electric appliances.
