before the work is completed can cause serious accidents such as electric shock or
fire.
If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant
comes in contact with a flame, it produces a toxic gas.
Installation work must be performed in accordance with national wiring standards by
authorized personnel only.
Except for EMERGENCY, never turn off main as well as sub breaker of the DX-kits
during operation. It will cause compressor failure as well as water leakage. First, stop
the DX-kit by operating the control unit, converter or external input device and then cut
the breaker.
Make sure to operate through the control unit, converter or external input device.
When the breaker is designed, locate it at a place where the users cannot start and
stop in the daily work.
CAUTION This mark indicates procedures which, if improperly performed,
might possibly result in personal harm to the user, or damage to
property.
Read carefully all security information before use or install the DX-kit.
Do not attempt to install the DX-kit or a part of the DX-kit by yourself.
This unit must be installed by qualified personnel with a capacity certificate for handling
refrigerant fluids. Refer to regulation and laws in use on installation place.
Th
e installation must be carried out in compliance with regulations in force in the place
of installation and the installation instructions of the manufacturer.
This unit is part of a set constituting the DX-kit. It must not be installed alone or with non-

2. ABOUT THIS PRODUCT
2.1. Precautions for using R410A refrigerant
WARNING
Do not introduce any substance other than the prescribed refrigerant into the
refrigeration cycle. If air enters the refrigeration cycle, the pressure in the refrigeration
cycle will become abnormally high and cause the piping to rupture.
If there is a refrigerant leak, make sure that it does not exceed the concentration limit.
If a refrigerant leak exceeds the concentration limit, it can lead to accidents such as
oxygen starvation.
Do not touch refrigerant that has leaked from the refrigerant pipe connections or other
area. Touching the refrigerant directly can cause frostbite.
If a refrigerant leak occurs during operation, immediately vacate the premises and
thoroughly ventilate the area. If the refrigerant comes in contact with a flame, it
produces a toxic gas.
2.2. Special tool for R410A
WARNING
To install a unit that uses R410A refrigerant, use dedicated tools and piping materials
that have been manufactured specifically for R410A use. Because the pressure
of R410A refrigerant is approximately 1.6 times higher than the R22, failure to
use dedicated piping material or improper installation can cause rupture or injury.
Furthermore, it can cause serious accidents such as water leakage, electric shock, or
fire.
Tool name Changes
Gauge manifold
The pressure in the refrigerant system is extremely high
and cannot be measured with a conventional gauge.
To prevent erroneous mixing of other refrigerants,
the diameter of each port has been changed. It is
recommended to use a gauge manifold with a high
pressure display range of –0.1 to 5.3 MPa and a low
pressure display range of –0.1 to 3.8 MPa.
Charging hose
To increase pressure resistance, the hose material and
base size were changed.
(The charging port thread diameter for R410A is 1/2 UNF
20 threads per inch.)
Vacuum pump
A conventional vacuum pump can be used by installing a
vacuum pump adapter.
Be sure that the pump oil does not backflow into the
system. Use one capable for vacuum suction of
–100.7 kPa (5 Torr, –755 mmHg).
Gas leakage detector Special gas leakage detector for R410A refrigerant.

4. INSTALLATION WORK
Correct initial installation location is important because it is difficult to move unit after it is
installed.
4.1. Selecting an installation location
Decide the mounting position together with the customer as follows.
WARNING
Select installation locations that can properly support the weight of the DX-kit. Install
the units securely so that they do not topple or fall.
CAUTION
Do not install the DX-kit in the following areas:
• Area with high salt content, such as at the seaside. It will deteriorate metal parts,
causing the parts to fail or the unit to leak water.
• Area filled with mineral oil or containing a large amount of splashed oil or steam,
such as a kitchen. It will deteriorate plastic parts, causing the parts to fail or the unit
to leak water.
• Area that generates substances that adversely affect the equipment, such as sulfuric
gas, chlorine gas, acid, or alkali. It will cause the copper pipes and brazed joints to
corrode, which can cause refrigerant leakage.
• Area that can cause combustible gas to leak, contains suspended carbon fibers or
flammable dust, or volatile inflammables such as paint thinner or gasoline. If gas
leaks and settles around the unit, it can cause a fire.
• Area where animals may urinate on the unit or ammonia may be generated.
Do not use the unit for special purposes, such as storing food, raising animals,
growing plants, or preserving precision devices or art objects.
It can degrade the quality of the preserved or stored objects.
Do not install where there is the danger of combustible gas leakage.
Do not install the unit near a source of heat, steam, or flammable gas.
Install the DX-kit, power supply cable, transmission cable, and remote controller cable
at least 1 m away from a television or radio receivers. The purpose of this is to prevent
TV reception interference or radio noise. (Even if they are installed more than 1 m
apart, you could still receive noise under some signal conditions.)
If children under 10 years old may approach the unit, take preventive measures so
that they cannot reach the unit.
Take precautions to prevent the unit from falling.
(1) Install the DX-kit on a place having a sufficient strength so that it withstands against
the weight of the DX-kit.
(2) Leave the space required to service the DX-kit.
(3) Install the unit where connection to the outdoor unit (or RB unit) is easy.
(4) Install the unit where the connection pipe can be easily installed.
(5) Install the unit where noise and vibrations are not amplified.
(6) Take servicing, etc., into consideration and leave the spaces.
(7) Do not install the unit where it will be exposed to direct sunlight.

4.3. Installing the unit
WARNING
Install the DX-kit in a location which can withstand a load of at least 5 times the weight
of the main unit and which will not amplify sound or vibration. If the installation location
is not strong enough, the DX-kit may fall and cause injuries.
If the job is done with the panel frame only, there is a risk that the unit will come loose.
Please take care.
Carrying in and installation of the unit should be performed by a sufficient number
of people and with sufficient equipment that is adequate for the weight of the unit.
Performing such work by an insufficient number of people or with inadequate
equipment could result in dropping of the unit or personal injury.

5. PIPE INSTALLATION
CAUTION
Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with
refrigerant R410A models. Also, when storing the piping, securely seal the openings
by pinching, taping, etc.
While welding the pipes, be sure to blow dry nitrogen gas through them.
5.1. Selecting the pipe material
CAUTION
Do not use existing pipes from another refrigeration system or refrigerant.
Use pipes that have clean external and internal sides without any contamination which
may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or water.
It is necessary to use seamless copper pipes.
Material : Phosphor deoxidized seamless copper pipes
It is desirable that the amount of residual oil is less than 40 mg/10 m.
Do not use copper pipes that have a collapsed, deformed, or discolored portion
(especially on the interior surface). Otherwise, the expansion valve or capillary tube
may become blocked with contaminants.
Improper pipe selection will degrade performance. As an air conditioner using R410A
incurs pressure higher than when using conventional (R22) refrigerant, it is necessary
to choose adequate materials.
• Thicknesses of copper pipes used with R410A are as shown in the table.
• Never use copper pipes thinner than those indicated in the table even if they are
available on the market.

5.5. Installing heat insulation
CAUTION
After checking for gas leaks (refer to the Installation Manual of the outdoor unit),
perform this section. Failure to do so may cause water leaks.
Implement heat insulation as shown in the diagram below.
(1) Mount the rubber sheets (accessories).
(2) Mount the heat insulations (accessories). There should be no gaps between the
insulation and the product.
(3) Secure to a pipe using 2 cable ties.
(1) Butyl rubber sheets
(Accessories)
(2) Heat insulations
(Accessories)
(3) Cable ties
(Large, accessories)
No gap
• Perform the work in (1), (2) and (3) for the 2 pipes.
• For the heat insulation on the separation tube (Optional parts) used to connect 2 EEV
units ,refer to the installation manual of the separation tube.
For construction other than mounting the EEV unit (e.g., mounting thermistors,
electrical wiring, and field settings, etc.), see the construction manual enclosed with
the control unit.
5.2. Pipe requirement
CAUTION
Refer to the Installation Manual of the outdoor unit for description of the length of
connecting pipe or for difference of its elevation.
• Use pipe with water-resistant heat insulation.
CAUTION
Install heat insulation around both the gas and liquid pipes. Failure to do so may
cause water leaks.
Use heat insulation with heat resistance above 120 °C. (Reverse cycle model only)
In addition, if the humidity level at the installation location of the refrigerant piping is
expected to exceed 70 %, install heat insulation around the refrigerant piping. If the
expected humidity level is 70 to 80 %, use heat insulation that is 15 mm or thicker and
if the expected humidity exceeds 80 %, use heat insulation that is 20 mm or thicker. If
heat insulation is used that is not as thick as specified, condensation may form on the
surface of the insulation. In addition, use heat insulation with heat conductivity of
0.045 W/(m·K) or less (at 20 °C).
5.3. Bending pipes
• The pipes are shaped by your hands or pipe bender. Be careful not to collapse them.
• Do not bend the pipes in an angle more than 90°.
• When pipes are repeatedly bend or stretched, the material will harden, making it difficult
to bend or stretch them any more. Do not bend or stretch the pipes more than 3 times.
CAUTION
To prevent breaking of the pipe, avoid sharp bends.
If the pipe is bent repeatedly at the same place, it will break.
5.4. Pipe connection
CAUTION
If air or another type of refrigerant enters the refrigeration cycle, the internal pressure
in the refrigeration cycle will become abnormally high and prevent the unit from
exerting its full performance.
Apply nitrogen gas while
brazing the pipes. Nitrogen
gas pressure:
0.02 MPa (= pressure felt
sufficiently on the back of
your hand)
Pressure regulating valve
Cap
Nitrogen gas
Brazing area
If a pipe is brazed without applying nitrogen gas, it will create an oxidation film.
This can degrade performance or damage the parts in the unit (such as the
compressor or valves).
Do not use flux to braze pipes. If the flux is the chlorine type, it will cause the pipes to
corrode. Furthermore, if the flux contains fluoride, it will adversely affect the refrigerant
pipe system such as by degrading the refrigerant oil.
For brazing material, use phosphor copper that does not require flux.
