Installing Distribution Joint Kit (for Triple)
(CZ-P3HPC2)
Check the system combination before installing the
distribution joints.
Three indoor units must be installed within the
same room.
Use the supplied tube connectors to adjust the tube
sizes of the distribution joints.
How to Install Distribution Joints
Use the supplied distribution joints to complete
refrigerant tubing work.
Install distribution joints so that the tubes are
horizontal after the branch point.
Orientation of distribution joints
Length requirement for strainer on main
distribution tube side
A
ttach 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 material. If
high temperatures and high humidity are expected
to occur inside the ceiling, add glass wool (16-20 kg/
m
3
, with a thickness of 10 mm or more) to the below
insulation materials and apply sufficient thermal
insulation.
Only the distribution joints are horizontal
with respect to the ground.
The collective tubes are vertical with respect
to the ground.
The collective tube and distribution
joint are horizontal with respect to the
ground.

Distribution joint insulation material (supplied)
Use the supplied insulation material.
The supplied insulation material include only a
tape for temporarily fastening.
Use insulation material or other material to seal
the joining lines so that there are no gaps.
Use vinyl tape or similar means to seal and
fasten the insulation materials in place.
Tubing insulation material
(field supply; thickness of more than 10 mm)
Tubing insulation material must be able to with
stand temperatures of at least 120°C.
Seal securely with vinyl tape (4 locations)
