Installation
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.
