5. PLACING THE UNIT
• Make sure the unit is installed level on a sufficiently strong base to
prevent vibration and noise. (Refer to figure 6 and 7)
• The base should support the unit with the extent larger than
hatched area in figure 6 and 7.
If protective rubber is to be attached, attach it to the whole face of
the base.
• The height of the base should be at least 150mm from the floor.
• Secure the unit to its base using foundation bolts. (Use four com-
mercially available M12-type foundation bolts, nuts, and washers.)
• The foundation bolts should be inserted 20 mm.
(Refer to figure 6)

Note
• When installing on a roof, make sure the roof floor is strong
enough and be sure to water-proof all work.
• Make sure the area around the machine drains properly by setting
up drainage grooves around the foundation.
Drain water is sometimes discharged from the outdoor unit when
it is running.
6. REFRIGERANT PIPING
Note
• All field piping must be installed by a licensed refrigeration tech-
nician and must comply with relevant local and national regula-
tions.
• After piping work is complete, do not open the shutoff valve under
any circumstances until “7. FIELD WIRING” and “8. TESTS AND
INSULATION WORK” are complete.
• Do not use flux when brazing the refrigerant piping. Use the phos-
phor copper brazing filler metal (BCuP-2 : JIS Z 3264, B-Cu93P-
710/795 : ISO 3677) which does not require flux.
(Flux has extremely harmful influence on refrigerant piping sys-
tems. For instance, if the chlorine based flux is used, it will cause
pipe corrosion or, in particular, if the flux contains fluorine, it will
damage the refrigerant oil.)
6-1 Selection of piping material and Refrigerant
branching kit
• Use only pipes which are clean inside and outside and which do
not accumulate harmful sulfur, oxidants, dirt, cutting oils, mois-
ture, or other contamination. (Foreign materials inside pipes
including oils for fabrication must be 30mg/10m or less.)
• Use the following items for the refrigerant piping.
Material :Jointless phosphor-deoxidized copper pipe
Size :See “6-5 Example of connection” to determine the cor-
rect size.
Thickness :Select a thickness for the refrigerant piping which
complies with national and local laws.
For R410A, the design pressure is 4.0 MPa (40-
bar).
The minimum thickness of piping according to
Japan’s High-Pressure Gas Safety Law (as of
January 2003) is shown below.
Temper grade (O type, 1/2H type) in the table indi-
cate the material types specified in JIS H 3300.
(unit : mm)
(unit : mm)
• For piping work, follow the maximum tolerated length, difference
in height, and length after a branch indicated in the “6-5 Example
of connection”.
• Outdoor unit multi connection piping kit and refrigerant branching
kit (sold separately) are needed for connection of piping between
outdoor units (in case of multi system) and piping branches.
Use only separately sold items selected specifically according to
the outdoor unit multi connection piping kit, the refrigerant branch-
ing kit selection in the “6-5 Example of connection”.
6-2 Protection against contamination
when installing pipes
Protect the piping to prevent moisture, dirt, dust, etc. from
entering the piping.
Note
Exercise special caution to prevent dirt or dust when passing pip-
ing through holes in walls and when passing pipe edges to the
exterior.
6-3 Pipe connection
• Be sure to perform nitrogen permutation or nitrogen blow when
brazing. (Refer to figure 8)
Brazing without performing nitrogen permutation or nitrogen blow
into the piping will create large quantities of oxidized film on the
inside of the pipes, adversely affecting valves and compressors in
the refrigerating system and preventing normal operation.
(Refer to figure 8)

2. Location to be brazed
3. Nitrogen
4. Taping
5. Handy valve
6. Regulator
• The pressure regulator for the nitrogen released when doing the
brazing should be set to about 0.02 MPa (0.2kg/cm

:
Enough to
feel a slight breeze on your cheek).
Prohibition
Do not use anti-oxidants when brazing the pipe joints.
Residue can clog pipes and break equipment.
