Installation Procedure CAUTION: Match the terminal block numbers and connection cord colors with those of the outdoor unit. Erroneous wiring may cause burning of the electric parts. Connect the connection cords firmly to the terminal block. Imperfect installation may cause a fire. 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. Wiring of indoor unit (1) Remove the electrical component box. Electrical component box CAUTION: Do not remove the screws. If the screws are removed, the electrical component box will fall. Electrical component box Remove the four tapping screws. (2) Pull out the electrical component box. (3) Remove the electrical component box cover. Electrical component box CAUTION: Be careful not to pinch the lead wires between the electrical component box and base. Base Remove the three tapping screws. Electrical component box cover (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. Indoor unit terminal block 12 3 Y/G Outdoor unit terminal block 1(N) 2(L) 3(C) Y/G WARNING: (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. CAUTION: (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. 16
