WARNING
Do not add power before finishing installation.
If the supply cord is damaged, it must be replaced by
the manufacturer, the service agent, or similarly
qualified persons for a hazard to be avoided.
Because the temperature of the refrigerant circuit will be
high, ensure that the interconnection cable is kept away
from the copper tube.
The appliance should be installed in accordance with
national wiring regulations.
Installation must be performed by authorized personnel
only in accordance with the requirements of National
Electrical Codes (NEC) and local electrical codes.
The air conditioner is a first-class electrical appliance. It
must be properly grounded by a professional with a
specialized grounding device. To avoid electric shock,
ensure that it is grounded effectively.
The yellow-green wire in the air conditioner is the
grounding wire and cannot be used for other purposes.
The grounding resistance should comply with National
Electric Safety regulations.
The appliance must be positioned so that the plug is
accessible.
All wires of both the indoor unit and the outdoor unit
should be connected by a professional.
If the length of power connection wire is insufficient, please
contact the supplier for a new one. Avoid extending the
wire by yourself.
