The cable connecting the outdoor and indoor units must be suitable for
outdoor use.
The plug must be accessible once the appliance has been installed.
Efficient grounding must be ensured.

Gas pipe connection
The pipe can be installed in 3 different
directions, as shown in the drawings below.
When the pipe is installed in position 1 or 3,
make a cut with cutex.
Install the pipe in the direction of the hole in
the wall and tape the copper pipes, drain
pipe and electrical wires together so that
water can flow freely.
Do not remove the pipe cap until it is
connected, to prevent dirt or moisture from
entering the pipe.
Do not bend the pipe too far and try to
extend or stretch it as shown in the pictures.
