Installation
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.
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 1.5 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.
