WARNING
1
The rated voltage of this product is 220-240 V A.C. 50 Hz.
Before turning on verify that the voltage is within the 198 V to 264 V range.
2
Always use a special branch circuit and install a special receptacle to supply power to the air conditioner.
3
Use a circuit breaker and receptacle matched to the capacity of the air conditioner.
4
Perform wiring work in accordance with standards so that the air conditioner can be operated safely and positively.
5
Install a leakage circuit breaker in accordance with the related laws and regulations and electric company
standards.
6
Never connect other electrical equipment to the power supply for this system.
CAUTION
1
Use care to wire properly. (Miss-wiring will result in damage.)
2
Never bundle the power supply cord, transmission cord and remote controller cord together. Bundling
these cords together will cause misoperation.
3
For transmission cord, only ground one side of the ground wire.
4
The total length of the transmission cord should not exceed 500 meters. Note that the total length of the
transmission cord can be extended to 2,000 meters if the optional signal amplifier is used.
5
The power source capacity must be the sum of the air conditioner current and the current of other electrical
appliances. When the current contracted capacity is insufficient, change the contracted capacity.
6
When the voltage is low and the air conditioner is difficult to start, contact the power company the voltage
raised.
