*1 Connect to the power switch which has a gap of 3 mm
or more when open to interrupt the source power phase.
(When the power switch is shut off, it must interrupt all
phases.)
*2 Use wires in conformity with design 60245 IEC 57.
*3 Never use pipes with thickness less than specified. The
pressure resistance will be insufficient.

Be sure to use wall hole
sleeve (C) to prevent
indoor/outdoor connecting
wire (A) from contacting
metal parts in the wall
and to prevent damage
by rodents in case the
wall is hollow.
After the leak test, ap-
ply insulating material
tightly so that there is
no gap.
When the piping is to be attached to a wall containing metals (tin
plated) or metal netting, use a chemically treated wooden piece 20 mm
or thicker between the wall and the piping or wrap 7 to 8 turns of insula-
tion vinyl tape around the piping.
To use existing piping, perform COOL operation for 30 minutes and
pump down before removing the old air conditioner. Remake flare ac-
cording to the dimension for new refrigerant.
Before installation
This installation manual is only for the indoor unit installation. In install-
ing the outdoor units, refer to the installation manual attached to each
outdoor unit. Any structural alternations necessary for the installation
must comply with the local building code requirements.
