conditioner current and the current of other electrical

appliances. When the current contracted capacity is

insufficient, change the contracted capacity.

2 When the voltage is low and the air conditioner is

difficult to start, contact the power company the

voltage raised.

3 This air conditioner must be connected to a power

source that has an electrical impedance of 0.16 Ω or

less or has a supply current of 100 A or greater. If the

power supply does not meet the specifications,

contact the power company.
