5 Installation
Notes on drilling hole in wall: You must
drill a hole in the wall for the refrigerant
piping, and the signal cable that will
connect the indoor and outdoor units.
1. Determine the location of the wall hole
based on the location of the outdoor
unit.
2. Using a 65-mm (2.5") core drill, drill a
hole in the wall.
C
When drilling the wall
hole, make sure to avoid
wires, plumbing, and other
sensitive components.
3. Place the protective wall cuff in the
hole. This protects the edges of the
hole and helps seal it when you finish
the installation process.
WARNING!
A
drilling into concrete,
eye protection is
recommended at all times.

For quick-connect
models, please refer to
C
the internal machine
manual for the installation
method of the connecting
pipe. The external
machine manual does not
repeat the instructions.
When connecting refrigerant piping,
do not let substances or gases other
than the specified refrigerant enter the
unit. The presence of other gases or
substances will lower the unit's capacity,
and can cause abnormally high pressure
in the refrigeration cycle. This can cause
explosion and injury.
