Step 1.4 Drilling a hole through the wall
Before fixing the installation plate to a wall and then fixing the indoor unit to the installation plate, a window frame, or a gypsum board, you must determine the position of a hole (with 65 mm inner diameter) through which the pipe bundle (consisting of power and communication cables, refrigerant pipes, and drain hose) will pass and then drill that hole.
1Determine the position of a 65 mm hole in consideration of the possible directions of the pipe bundle and the minimum distances between the hole and the installation plate.

CAUTION
•If changing the pipe direction from left to right, do not drastically bent it but slowly turn it in the opposite direction as shown. Otherwise, the pipe may be damaged in the process.

Pipe bundle hole: Ø 65 mm
2Drill the hole.
CAUTION
•Be sure to drill only one hole.
•Make sure that the hole slants downwards so that the drain hose slants downwards to drain water well.

Step 1.5 Taping the pipes, cables, and drain hose
1Wrap foam insulation on parts without insulation on the ends of the refrigerant pipes, as shown in the figure. This wrapping minimises condensation problem.

2Wind the refrigerant pipes, power cable, communication cable and drain hose with vinyl tape to make a pipe bundle.
