The manufacturer shall not assume any liability for the damage caused by not observing the
description of this manual.
WARNING
General
• Do not modify the products. Do not also disassemble or modify the parts. It may cause a re,
electric shock or injury.
• Before starting to install the Dx-coil interface, read through the Installation Manual carefully,
and follow its instructions to install the Dx-coil interface.
• Only a qualied installer or qualied service person is allowed to do installation work.
Inappropriate installation may result in water leakage, electric shock or re.
• Do not use any refrigerant different from the one specied for complement or replacement.
Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may
result in a failure or explosion of the product or an injury to your body.
• Before opening the electrical control box cover of the air handling unit or service panel of the
outdoor unit, set the circuit breaker to the OFF position. Failure to set the circuit breaker to
the OFF position may result in electric shocks through contact with the interior parts. Only
a qualied installer (*1) or qualied service person (*1) is allowed to remove the electrical
control box cover of the air handling unit or service panel of the outdoor unit and do the work
required.
• Before carrying out the installation, maintenance, repair or removal work, set the circuit
breaker to the OFF position. Otherwise, electric shocks may result.
• Place a “Work in progress” sign near the circuit breaker while the installation, maintenance,
repair or removal work is being carried out. There is a danger of electric shocks if the circuit
breaker is set to ON by mistake.
• Only a qualied installer (*1) or qualied service person (*1) is allowed to undertake work at
heights using a stand of 50 cm or more.
• Wear protective gloves and safety work clothing during installation, servicing and removal.
• When work is performed at heights, use a ladder which complies with the ISO 14122
standard, and follow the procedure in the ladder’s instructions. Also wear a helmet for use in
industry as protective gear to undertake the work.
• Before working at heights, put a sign in place so that no-one will approach the work location,
before proceeding with the work. Parts and other objects may fall from above, possibly injuring
a person below. While carrying out the work, wear a helmet for protection from falling objects.
• The refrigerant used by this Dx-coil interface is the R410A.
• The Dx-coil interface must be transported in stable condition. If any part of the product is
broken, contact the dealer.
• Do not move or repair any unit by yourself. There is high voltage inside the unit. You may get
electric shock when removing the cover and main unit.
• This appliance is intended to be used by expert or trained users in shops, in light industry, or
for commercial use by lay persons.
• Do not add any other devices without factory advice.
Installation
• Install the air conditioner securely in a location where the base can sustain the weight
adequately. If the strength is not enough, the unit may fall down resulting in injury.
• Follow the instructions in the Installation Manual to install the air conditioner. Failure to follow
these instructions may cause the product to fall down or topple over or give rise to noise,
vibration, water leakage or other trouble.
• Carry out the specied installation work to guard against the possibility of high winds and
earthquake.
If the air conditioner is not installed appropriately, a unit may topple over or fall down,
causing an accident.
01_1135451001 EN edit-1.indd 301_1135451001 EN edit-1.indd 3 4/7/2566 BE 09:254/7/2566 BE 09:25

• If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with re, noxious gas may generate.
• Helmet must be worn to protect your head from falling objects. Especially, when you work
under an inspection opening, helmet must be worn to protect your head from falling objects
from the opening.
Selection of installation location
• When the air conditioner is installed in a small room, provide appropriate measures to ensure
that the concentration of refrigerant leakage occur in the room does not exceed the critical
level.
• Do not install in a location where ammable gas leaks are possible. If the gas leak and
accumulate around the unit, it may ignite and cause a re.
• To transport the Dx-coil interface, wear shoes with additional protective toe caps.
• Do not place any combustion appliance in a place where it is directly exposed to the wind of
air conditioner, otherwise it may cause imperfect combustion.
Refrigerant piping
• Install the refrigerant pipe securely during the installation work before operating the
air conditioner. If the compressor is operated with the valve open and without refrigerant
pipe, the compressor sucks air and the refrigeration cycles is over pressurized, which may
cause a injury.
• After the installation work, conrm that refrigerant gas does not leak. If refrigerant gas leaks
into the room and ows near a re source, such as a cooking range, noxious gas may be
generated.
• When the air conditioner has been installed or relocated, follow the instructions in the
Installation Manual and purge the air completely so that no gases other than the refrigerant
will be mixed in the refrigerating cycle. Failure to purge the air completely may cause the
air conditioner to malfunction.
• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not slack.
• Due to the pressure of R410A is higher than that of other refrigerant (ex. R22), be sure to
use the pipe specic for R410A and use the special tool for the pipe processing.
Electrical wiring
• Only a qualied installer (*1) or qualied service person (*1) is allowed to carry out the
electrical work of the air conditioner. Under no circumstances must this work be done by an
unqualied individual since failure to carry out the work properly may result in electric shocks
and/or electrical leaks.
• To connect the electrical wires, repair the electrical parts or undertake other electrical jobs,
wear gloves to provide protection for electricians, insulating shoes and clothing to provide
protection from electric shocks. Failure to wear this protective gear may result in electric
shocks.
• Use wiring that meets the specications in the Installation Manual and the stipulations in the
local regulations and laws. Use of wiring which does not meet the specications may give
rise to electric shocks, electrical leakage, smoking and/or a re.
• Connect earth wire. (Grounding work) Incomplete grounding causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and lightning conductor or telephone
earth wires.
• After completing the repair or relocation work, check that the earth wires are connected
properly.
• Install a circuit breaker that meets the specications in the Installation Manual and the
stipulations in the local regulations and laws.
• Install the circuit breaker where it can be easily accessed by the agent.
• When installing the circuit breaker outdoors, install one which is designed to be used
outdoors.
01_1135451001 EN edit-1.indd 401_1135451001 EN edit-1.indd 4 4/7/2566 BE 09:254/7/2566 BE 09:25

– 5 –
• Under no circumstances the power wire must not be extended. Connection trouble in the
places where the wire is extended may give rise to smoking and/or a re.
• Electrical wiring work shall be conducted according to law and regulation in the community
and Installation Manual. Failure to do so may result in electrocution or short circuit.
• Make sure that the circuit breaker is attached. If it is not, the electric shock may be caused.
• Do not use the fuse other than the correct capacity. Use of wire or copper wire may result in
re or malfunction.
• Ensure that the power is the rated voltage and use the circuit special for the Dx-coil interface.
Test run
• Before operating the air conditioner after having completed the work, check that the electrical
control box cover of the air handling unit and service panel of the outdoor unit are closed,
and set the circuit breaker to the ON position. You may receive an electric shock if the power
is turned on without rst conducting these checks.
• If there is any kind of trouble (such as a check display has appeared, smell of burning,
abnormal sounds, the air conditioner fails to cool or heat or water is leaking) has occurred in
the air conditioner, do not touch the air conditioner yourself but set the circuit breaker to the
OFF position, and contact a qualied service person. Take steps to ensure that the power
will not be turned on (by marking “out of service” near the circuit breaker, for instance) until
qualied service person arrives. Continuing to use the air conditioner in the trouble status
may cause mechanical problems to escalate or result in electric shocks or other trouble.
• After the work has nished, use an insulation tester set (500 VMΩ) to check the resistance is
1 MΩ or more between the charge section and the non-charge metal section (Earth section).
If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s
side.
• Upon completion of the installation work, check for refrigerant leaks and check the insulation
resistance and water drainage. Then conduct a test run to check that the air conditioner is
operating properly.
Explanations given to user
• Upon completion of the installation work, tell the user where the circuit breaker is located.
If the user does not know where the circuit breaker is, he or she will not be able to turn it off
in the event that trouble has occurred in the air conditioner.
• After the installation work, follow the Owner’s Manual to explain to the customer how to use
and maintain the unit.
Relocation
• Only a qualied installer (*1) or qualied service person (*1) is allowed to relocate the
air conditioner. It is dangerous for the air conditioner to be relocated by an unqualied
individual since a re, electric shocks, injury, water leakage, noise and/or vibration may
result.
• When carrying out the pump-down work shut down the compressor before disconnecting the
refrigerant pipe. Disconnecting the refrigerant pipe with the service valve left open and the
compressor still operating will cause air or other gas to be sucked in, raising the pressure
inside the refrigeration cycle to an abnormally high level, and possibly resulting in rupture,
injury or other trouble.
Repair • Maintenance
• Request the repair to the distributor that you made your purchase from.
• If there is a defect in the repair, the re, electric shock may be caused.
• Turn off the circuit breaker of the entire system including the AHU and the outdoor unit when
performing the repair or the maintenance.
(*1) Refer to the “Denition of Qualied Installer or Qualied Service Person”.

Selection of installation place
Avoid installation in the following kinds of locations.
• Dx-coil interface is recommended to be installed indoors. Install it in a location where there is
no rain, wind, and direct sunlight.
• Do not install in locations where there is a machine generating high frequency. Failure to do
so may cause a wrong operation or an abnormality.
• Do not install in locations with atmospheres with mist of oil (including machine oil) or dense
vapor, or locations containing salt such as the coast area, or locations with acidic or alkaline
atmospheres, or locations where sulfurizing gas are generated such as areas with hot
springs. Use in inappropriate locations result in malfunctions.
• Do not put any vessel contains the water in the vicinity of the indoor unit (including Dx-coil
controller, Dx-valve kit).
If the water spills and enters into the inside of the unit, the electric insulation deteriorates and
may result in an electric shock.
• Make sure that the air lter is attached on the indoor unit. If it is not, the dust clogs in the
heat exchanger etc. in the air conditioner and may result in water leakage or defrosting.
• Separate the television or radio from the air conditioner or remote controller at least 1 m.
Failure to do so may cause the disturbance of the image, or the noise.
• Do not use for special-purpose (Foods, animals and plants, precision machine, storage of
the artwork etc.).
• Do not use in locations where there is anything that would be compromised by wetness.
The mist or water dew drop may result in damage.
• Do not install in locations where organic solvents are being used.
• Do not install in locations near doors or windows where the air conditioner may come into
contact with high humidity outside air. Condensation may occur as a result.
• Do not install in locations where special sprays are used frequently. The location has an
impact on the insulation of the equipment and may cause the ignition.
• Do not install in locations with high-humidity atmosphere. Doing so may cause condensation
of the equipment, splashing of water from the air outlet side of indoor unit.
Ex. 1) Installation to inside of the ceiling where is high humidity.
2) Installation to inside of the ceiling used for the path of the fresh air intake.
3) Installation to a kitchen.
• In the above cases, additionally attach the heat insulator (grass wool etc.) to all positions of
the air conditioner, which come to contact with the high-humidity atmosphere.
* The guideline of the high-humidity condition is “dew-point temperature: 23°C or higher”,
however, the decision should be made according to the trial operation conducted in each
installation location.
• Install in locations that ensure the sufcient space needed for the service so that the
equipment does not come to contact with the surface of the wall or the ceiling.
• Fix the Dx-coil controller, Dx-valve kit to the stable surface. Failure to do so may cause the
vibration or the noise.
• Do not install the Dx-coil controller, Dx-valve kit to the locations where there is a temperature
difference with the ambient temperature. Failure to do so may result in condensation, rust, or
malfunction. Ex. The sheet metal side surface of the AHU outlet.
• Install the Dx-valve kit to where the noise is no problem due to the Dx-valve kit makes
the refrigerant noise. Also, it may make the refrigerant noise when other indoor units are
operating even if the AHU is stopping like defrosting.
• Do not install in locations with the high temperature or the high-humidity atmosphere of 52°C
or more / RH 80% or more. Also, do not install it in a place where dew condensation occurs
inside the Dx-coil controller.
• When installing the Dx-valve kit and the Dx-coil controller into the Air handling unit, do not
install it where it is exposed to the cooled air of the secondary side of the heat exchanger.
• Do not install in locations where iron or other metal dust is present. If iron or other metal
dust adheres to or collects on the interior of the Dx-coil controller, it may spontaneously
combusted and start a re.

Dx-valve kit and connection of the pipe
• Be sure to cool the strainer and PMV valve body using a wet cloth so that the body temperature does not exceed
120°C while brazing.
• For the connection pipe, it may vibrate during the defrosting operation. Carry out the installation work so that the
connection pipe does not break after a long-term use.
Sensor holders
• To ensure reliable operation, all Sensor holders must be tted by brazing.
• Be careful of that the brazing material does not enter into the sensor holder when attaching the TC1, TC2 and TCJ
sensor holder.
TC1 sensor
• Install it in the collecting part of the gas header.
TC2 sensor
• Install it in the between the liquid pipe distributor and the PMV.
(TC2 sensor is attached to the refrigerant cycle of AHU.)
TCJ sensor
• Install it in the pass where the temperature of the capillary tube is the lowest.
• Keep a distance of 50 mm ± 25 mm from the end plate.
TA, TF sensor
• Install the TA, TF sensor where the better of air ow.
• The TA sensor must be located in the Return Air position, prior to mixing with any fresh air.
• Install the TF sensor in a place where the discharge air temperature is uniform.
If the TC1, TC2, or TCJ sensor are easy to be subjected to the surrounding thermal effect, cover them with the heat
insulator material, and x them with the xing band.
If the lead wires of various sensors are left over, protect them from the effects of external force, heat, and water, and x
them with a xing band. If the lead wires of various sensors do not reach, use the Optional Sensor 40VA010-S8FATEE
(Temperature sensor with 10 m wiring length).
