Step 1.3 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.
1. Determine 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.

2. Drill 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 1.4 Taping the pipes, cables, and
drain hose
1. Wrap foam insulation on parts without insulation on
the ends of the refrigerant pipes, as shown in the
figure. This wrapping minimises condensation problem.

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