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 according to the exit position of the pipe when facing the wall:
Right(A)
Left(B)
Underside(C)
Rear
1Cut out the appropriate
2Smooth the cut edges.
3Remove 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 |
1/4 inch (6.35mm) 3/8 inch (9.52mm) 1/2 inch (12.80mm) 5/8 inch (15.88mm)
10.1~12.3ft•lb (140~170 kgf•cm) 18.1~20.3ft•lb (250~280 kgf•cm) 27.5~30.4ft•lb (380~420 kgf•cm) 31.8~34.7ft•lb (440~480 kgf•cm)
If you want to shorten or extend pipes, refer to page 9.
4Cut off the remaining foam insulation.
5If necessary, bend the pipe to fit along the bottom of the indoor unit. Then pull it out through the appropriate hole.
The pipe should not project from the rear of the indoor unit.
The bending radius should be 4 inch(100mm) or more.
6Pass the pipe through the hole in the wall.
7For further details on how to connect to the outdoor unit and purge the air, refer to page 13.
The pipe will be insulated and fixed permanently into position after finishing the installation and the gas leak test; refer to page 14 for further details.
