Grounding
This air conditioner must be grounded without fail.
• Grounding is necessary not only to safeguard against the possibility
of receiving an electric shock but also to absorb both static, which is
generated by high frequencies and held in the surface of the outdoor unit,
and noise since the air conditioner incorporates a frequency conversion
device (called an inverter) in the outdoor unit.
• If the air conditioner is not grounded, users may receive an electric shock
if they touch the surface of the outdoor unit and that unit is charged with
static.
