Connecting the assembly cable
• End of the wire must be circular.
• After connecting the cables, make sure terminal numbers on the indoor/outdoor unit matches.
•Screws on terminal block must not be unscrewed with the torque less than 12kgf•cm.
10.Connect the grounding conductor to the grounding terminals.
11.Close the terminal board cover by tightening the screw carefully.
• In Russia and Europe, consult with the supply authority to determine the supply system impedance before
installation.
• Connect the wires firmly so that wires can not be pulled out easily. (If they are loose, it could cause
•Connect the wires according to color codes, referring to the wiring diagram.
•The power cable and the interconnection cable should be selected according to the specification in page 28.
Installing and connecting the assembly pipe of the indoor unit

There are 2 refrigerant pipes of different diameters:
•The smaller one is for the liquid refrigerant
•The larger one is for the gas refrigerant
A short pipe is already fitted to the air conditioner. You may need to extend the pipe using the assembly pipe (optional).
The connection procedure for the refrigerant pipe varies |

1.Cut out the appropriate
2.Smooth the cut edges.
3.Remove the protection caps of the pipes and connect the assembly pipe to each pipe. Tighten the nuts first with your hands, and then with a torque wrench, applying the following torque:
Outer Diameter | Torque (kgf•cm) |
|
|
ø6.35 mm | 140~170 |
ø9.52 mm | 250~280 |
ø12.70 mm | 380~420 |
ø15.88 mm | 440~480 |
ø19.05 mm | 990~1210 |
ø22.23 mm | 990~1210 |
• If you want to shorten or extend the pipes, refer to page 31~32.
