Three indoor units must be installed within the
GB
same room.

How to Install Distribution Joints
FR
Use the supplied distribution joints to complete refrig-
erant tubing work.
Install distribution joints so that the tubes are horizon-
tal after the branch point.
DE
Orientation of distribution joints
Only the distribution joints are
horizontal with respect to the ground.
IT
The collective tubes are vertical with
respect to the ground.
PT
GR
ES
<Gas tube side>
Length requirement for strainer on main
distribution tube side
Attach a straight tube 500 mm or longer to the
main tubing side of the distribution joint (for
both liquid and gas tubing).
Tubing insulation
Be sure to apply thermal insulation to both the
liquid and gas tubing.
Depending on the conditions inside the ceiling,
condensation may form on the insulation mate-
rial. If high temperatures and high humidity are
expected to occur inside the ceiling, add glass
3
wool (16 – 20 kg/m
, with a thickness of 10 mm
or more) to the below insulation materials and
apply sufficient thermal insulation.
