O
Install the indoor unit higher than 2.5m from the floor to avoid the injury caused by the oper ation of the fan.
(except the window-type air conditioner)
O The manufacturer is not responsible for any accidents or injury caused by an incorrect installation.
O When installing the built-in type air conditioner, keep all electric cables such as the power cable and the connection cord in
pipes, ducts, or cable channel
s to protect them from the danger of impact or any other incidents.
1-2 Power supply and circuit breaker
O If the power cord of the air conditioner is damaged, it must be replaced by the manufacturer or a qualified person in order
to avoid a hazard.
O The air conditioner must be plugged into an independent circuit if applicable or connect the pow
er cable to the auxiliary circuit
breaker .
An all pole disconnection form the power supply must be incorporated in the fixed wiring with a con tact opening of>3mm.
