Precautions for R-410A
■The refrigerant requires strict cautions for keeping the
system clean, dry and tight.
- Clean and dry
Foreign materials (including mineral oils or moisture)
should be prevented from getting mixed into the
system.
- Tight
Read "7.5. Precautions on refrigerant piping" on
page 5 carefully and follow these procedures correctly.
■Since R-410A is a mixed refrigerant, the required
additional refrigerant must be charged in its liquid
state. (If the refrigerant is in state of gas, its
composition changes and the system will not work
properly).
■The connected indoor units must be indoor units
designed exclusively for R-410A.
Read "7. Refrigerant piping" on page 4 carefully and follow
these procedures correctly.
Since design pressure is 4.0 MPa or 40 bar, pipes of larger
wall thickness may be required. Refer to paragraph
"7.1. Selection of piping material" on page 4.

3. MAINCOMPONENTS
For main components and function of the main components, refer to
the Engineering Data Book.
4. SELECTIONOFLOCATION
This is a class A product. In a domestic environment this product may
cause radio interference in which case the user may be required to
take adequate measures.
This unit, both indoor and outdoor, is suitable for
installation in a commercial and light industrial
environment. If installed as a house-hold appliance it could
cause electromagnetic inteference.
The inverter units should be installed in a location that meets the
following requirements:
1The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation. If
not, the unit may fall over and cause injury.
2The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet is available. (Refer to
figure 1 and choose one of the possibilities).
In case of an installation site where only the sides A+B have
obstacles, the wall heights have no influence on any indicated
service space dimensions.
2.1. Combination
The indoor units can be installed in the following range.
■Always use appropriate indoor units compatible with R-410A.
To learn which models of indoor units are compatible with
R-410A, refer to the product catalogs.

Keep the unit upright in order to avoid compressor damage.
1Personal computer or radio
2Fuse
3Earth leakage breaker
4Remote controller
5Indoor unit
In extreme circumstances you should keep distances of
3 m or more and use conduit tubes for power and
transmission lines.
■In heavy snowfall areas, select an installation site
where snow will not affect operation of the unit.
■The refrigerant R-410A itself is nontoxic,
nonflammable and is safe. If the refrigerant should
leak however, its concentration may exceed the
allowable limit depending on room size. Due to this it
could be necessary to take measures against
leakage.
■Do not install in the following locations.
• Locations where acidic or alkaline vapour is
present.
• Locations where sulfurous acids and other corrosive
gases may be present in the atmosphere.
Copper piping and soldered joints may corrode,
causing refrigerant to leak.
• Locations where there is mist of mineral oil, oil spray or
vapor for example a kitchen.
Plastic parts may deteriorate, and cause them to
fall out or water to leak.
• Locations where the air contains high levels of salt
such as that near the ocean.
• Locations where flammable gases may leak, where
thinner, gasoline, and other volatile substances are
handled, or where carbon dust and other incendiary
substances are found in the atmosphere.
Leaked gas may accumulate around the unit, causing
an explosion.
• Locations where equipment that produces electro-
magnetic waves is found.
The electromagnetic waves may cause the control
system to malfunction, preventing normal operation.
• Locations where voltage fluctuates a lot, such as
that in factories.
• In vehicles or vessels.
■During installation, take strong winds, typhoons or
earthquakes into account.
Improper installation may result in fall over of the unit.
2Choose on beforehand the path along which the unit is to be
brought in.
3Lift the unit preferably with a crane and 2 belts of at least 8 m
long.
4When lifting the unit with a crane, always use protectors to
prevent belt damage and pay attention to the position of the
unit's centre of gravity.
NOTE
Use belt sling of ≤20 mm width which adequately
bears the weight of the unit.

7. REFRIGERANTPIPING
Use R-410A to add refrigerant.
All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.
CAUTION TO BE TAKEN WHEN BRAZING
REFRIGERANT PIPING
■Do not use flux when brazing copper-to-copper
refrigerant piping. (Particularly for the HFC refrigerant
piping) Therefore, use the phosphor copper brazing
filler metal (BCuP) which does not require flux.
Flux has extremely harmful influence on refrigerant
piping systems. 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.
■Be sure to perform a nitrogen blow when brazing.
(Brazing without performing nitrogen replacement or
releasing nitrogen 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.)
■After completing the installation work, check that the
refrigerant gas does not leak.
To xic gas may be produced if the refrigerant gas leaks
into the room and when it comes in contact with a
source of fire.
If any leak would happen:
•ventilate the area immediately.
• do not directly touch the refrigerant that leaks.
Frostbite may be caused.
NOTE
Installation tools:
Make sure to use installation tools (gauge manifold
charge hose, etc.) that are exclusively used for R-410A
installations to withstand the pressure and to prevent
foreign materials (e.g. mineral oils such as SUNISO
and moisture) from mixing into the system.
(The screw specifications differ for R-410A and
R-407C.)
Vacuum pump (use a 2-stage vacuum pump with a
non-return valve):
■Make sure the pump oil does not flow oppositely
into the system while the pump is not working.
7.1. Selection of piping material
■Construction material: phosphoric acid deoxidized seamless
copper for refrigerant.
■Temper grade: use piping with temper grade in function of the
pipe diameter as listed in table below.
■The pipe thickness of the refrigerant piping should comply with
relevant local and national regulations. The minimal pipe
thickness for R-410A piping must be in accordance with the
table below.
