Electric wiring
(4) Wiring
1.Remove the cord clamp.
2.Process the end of the connection cords to the dimensions shown in the right figure.
3.Connect the end of the connection cord fully into the terminal block.
4.Fasten the connection cord with a cord clamp.
5.Fasten the end of the connection cord with the screw.
(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.

DANGER OF BODILY INJURY OR DEATH
TURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFORE MAKING ANY ELECTRIC
CONNECTIONS.
GROUND CONNECTIONS MUST BE COMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS.
WARNING
Selection of size of power supply and interconnecting wires.
Precautions for Electric wiring
Select wire sizes and circuit protection from table below. (This table shows 20 m length wires with less than 2% voltage
drop.)
Electric wiring work should be conducted only by authorized personnel.
Do not connect more than three wires to the terminal block. Always use round type crimped terminal lugs with insulated
grip on the ends of the wires.
Use copper conductor only.

WARNING:
(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.
