3. SELECTING THE INSTALLATION SITE
When moving the unit during or after unpacking, make sure to lift it by holding its lifting lugs. Do not
exert any pressure on other parts, especially the refrigerant piping, drain piping and flange parts.
If you think the humidity inside the ceiling might exceed 30°C and RH 80%, reinforce the insulation on
the unit body. Use glass wool or polyethylene foam as insulation so that it is no thicker than 10 mm and
fits inside the ceiling opening.
Outdoor Unit
AVOID :
Heat sources and exhaust fans, etc. (Fig. 1-13)
Damp, humid or uneven locations.
DO :
Choose a place as cool as possible.
Choose a place that is well ventilated and outside air
temperature does not exceed maximum 45°C constantly.
Allow enough room around the unit for air intake/exhaust
and possible maintenance. (Fig. 1-14)
Use lug bolts or equal to bolt down unit, reducing
vibration and noise.
If cooling operation is to be used when the outdoor
air temperature is –5°C or below, install a duct on the
outdoor unit.

CAUTION
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
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 material. If high temperatures and high
humidity are expected to occur inside the ceiling, add glass wool
(16 – 20 kg/m

, with a thickness of 10 mm or more) to the below
insulation materials and apply suffi cient 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.
Seal securely with vinyl tape (4 locations)
Refrigerant tubing (fi eld supply)
Tubing insulation material (fi eld supply;
thickness of more than 10 mm) Tubing
insulation material must be able to withstand
temperatures of at least 120°C
Refrigerant tubing (fi eld supply)
More than 500mm
