(1) The power source capacity must be the sum of the room air 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 too low and the air conditioner is difficult to start, contact the power company the voltage raised.
(1) Always use a special branch circuit and install a special receptacle to supply power to the room air conditioner.
(2) Use a circuit breaker and receptacle matched to the capacity of the room air conditioner.
(3) The circuit breaker is installed in the permanent wiring. Always use a circuit that can trip all the poles of the wiring and
has an isolation distance of at least 3mm between the contacts of each pole.
(4) Perform wiring work in accordance with standards so that the room 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.
Match the terminal block numbers and connection cord colors with those of the outdoor unit. Erroneous wiring may cause

Always fasten the outside covering of the connection cord with the cord clamp.(If the insulator is chafed, electric leakage
may occur.)
Always connect the ground wire.
