1. SAFETY PRECAUTIONS
• Be sure to read this Manual thoroughly before installation.
• The warnings and precautions indicated in this Manual contain important information pertaining to your safety. Be sure to observe them.
• Hand this Manual, to the customer. Request the customer to keep them on hand for future
use, such as for relocating or repairing the unit.
• For installation of the air handling unit (heat exchanger), refer to the installation manual
for the air handling unit.
WARNING
This mark indicates procedures which, if improperly
performed, might lead to the death or serious injury of the
user.
Request your dealer or a professional installer to install the DX-kit in accordance with
this Installation Manual. An improperly installed unit can cause serious accidents such
as water leakage, electric shock, or fi re. If the DX-kit is installed in disregard of the
instructions in the Installation Manual, it will void the manufacturer’s warranty.
Do not turn ON the power until all work has been completed. Turning ON the power
before the work is completed can cause serious accidents such as electric shock or
fi re.
If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant
comes in contact with a fl ame, 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 nonauthorized by the manufacturer.
Always use a separate power supply line protected by a circuit breaker operating on all
wires with a distance between contact of 3mm for this unit.
The unit must be correctly earthed (grounded) and the supply line must be equipped with
a differential breaker in order to protect the persons.
The units are not explosion proof and therefore should not be installed in explosive
atmosphere.
Never touch electrical components immediately after the power supply has been turned
off. Electric shock may occur. After turning off the power, always wait 5 minutes before
touching electrical components.
This unit contains no user-serviceable parts. Always consult authorized service
personnel to repairs.
When moving, consult authorized service personnel for disconnection and installation of
the unit.
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
fi re.
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.

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 suffi cient 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 amplifi ed.
(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 suffi cient number
of people and with suffi cient 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.

4. INSTALLATION WORK
Correct initial installation location is important because it is diffi cult 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 fi lled 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 fi bers or
fl ammable dust, or volatile infl ammables such as paint thinner or gasoline. If gas
leaks and settles around the unit, it can cause a fi re.
• 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 fl ammable 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.)
