1. SAFETYCONSIDERATIONS
The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.
WARNING
If the warning is not observed, it may cause serious casualties.
CAUTION
If the caution is not observed, it may cause injury or damage to the
equipment.
Warning
■
Ask your dealer or qualified personnel to carry out installation work
Do not install the machine by yourself.
Improper installation may result in water leakage, electric shocks
or fire.
■Perform installation work in accordance with this installation
manual.
Improper installation may lead to water leakage, electric shocks
or fire.
■Be sure to use only the specified accessories and parts for
installation work.
Failure to use the specified parts may result in water leakage,
electric shocks, fire, or the unit falling.
■When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, overheat of the terminals,
electric shocks or a fire may be caused.
■If refrigerant gas leaks during installation work, ventilate the area
immediately.
Toxic gas may be produced if refrigerant gas comes into contact
with fire.
■After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
■Before touching electric terminal parts, turn off power switch.
■Live parts can be easily touched by accident.
Do never leave the unit unattended during installation or
servicing when the service panel is removed.
■When planning to relocate former installed units, you must first
recover the refrigerant after the pumping-down operation. Refer
to chapter "Precaution for pumping-down operation" on page 10.
Caution
■Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation.
Improper drain piping may cause water leakage, and make the
furnitures get wet.
■Install the indoor and outdoor units, power wire and connecting
wire at least 1 meter away from televisions or radios to prevent
image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not
be sufficient to eliminate the noise.)
■Do not rinse the outdoor unit. This may cause electric shocks or
fire.

Precautions for R410A
■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 "7.6. Precautions on refrigerant piping" on
page 5 carefully and follow these procedures
correctly.
■Since R410A 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 R410A.
Read "7. Refrigerant piping" on page 4 carefully and follow
these procedures correctly.
Refer to figure 2.

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.
■Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.
■Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.
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.

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 R410A 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.
4Lift the unit preferably with a crane and 2 belts of at least 8 m
long. (See figure 4)
Always use protectors to prevent belt damage and pay attention
to the position of the unit's centre of gravity.
NOTE
Use a belt sling of ≤20 mm wide that adequately
bears the weight of the unit.
5If a forklift is to be used, preferably
transport the unit with pallet first,
then pass the forklift arms through
the large rectangular openings on
the bottom of the unit.
5.1 From the moment you use a forklift to
move the unit to its final position, lift
the unit under the pallet.
5.2 Once at final position, unpack the unit and pass the forklift arms
through the large rectangular openings on the bottom of the unit.
NOTE
Use filler cloth on the forklift arms to prevent
damaging the unit. If the paint on the bottom
frame peels off, the anti corrosion effect may
decrease.
6. UNPACKINGANDPLACINGTHEUNIT
■Remove the four screws fixing the unit to the pallet.
■Make sure the unit is installed level on a sufficiently strong base
to prevent vibration and noise.
■Fasten the unit in place using four anchor bolts M12.
■Make sure the base under the unit is more than 765 mm.
■The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete) as indicated in figure 5.

■Prepare a water drainage channel around the
foundation to drain waste water from around the unit.
■If the unit is to be installed on a roof, check the
strength of the roof and its drainage facilities first.
■If the unit is to be installed on a frame, install the
waterproofing board within a distance of 150 mm
under the unit in order to prevent infiltration of water
coming from under the unit.
■When installed in a corrosive
environment, use a nut with a
resin clip plate (1) to protect the
1
nut tightening part from rust.
PRECAUTION
Block all gaps in the holes for passing out piping and wiring using
sealing material (field supply). (Small animals may enter the
machine.)
Example: passing piping out through the front. (See figure 10)

7. REFRIGERANTPIPING
Use R410A 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.
Toxic 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.
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 R410A piping must be in accordance with the table
below.

NOTE
■For new installations, use the standard pipe sizes.
■When using existing pipes, size-up is allowed as
mentioned in the table above.
Size up is only allowed for pair combination (L1).
Additional restrictions towards allowable pipe
lenghts, as mentioned in the table "Allowable pipe
length" on page 5, must be taken into account.
Not using the standard pipe size may result in
capacity decrease. The installer must
acknowledge this and judge this very carefully in
function of the complete installation.

Installation tools:
Make sure to use installation tools (gauge manifold
charge hose, etc.) that are exclusively used for R410A
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 R410A and
R407C.)
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.
