leaked corrosive gas or flammable gas.
If there leaked gas around the unit, it may cause explosion
and other accidents.
●Do not use extension cords for electrical connections. If
the electric wire
is not long enough, please contact a local service center
authorized and ask for a proper electric wire.
Poor connections may lead to electric shock or fire.
●Use the specified types of wires for electrical connections
between the indoor and outdoor units. Firmly clamp the
wires so that their terminals receive no external stresses.
Electric wires with insufficient capacity, wrong wire
connections and insecure wire terminals may cause electric
shock or fire.
