Make sure to perform grounding work.
XDo not connect the ground wire to a gas pipe, water pipe, lightning rod or telephone grounding. Improper grounding
could cause electric shock.
Wiring must be connected with the designated wires and it must be fixed securely so that it does not apply any external
force to the connection part of the terminals.
XIf connection for fixation is not properly done, it may cause heat generation or fire.
Neatly arrange the wires in the electrical parts to make sure that electrical cover is closed securely without any gaps.
XIf the cover is not properly closed, heat may generate on the electrical terminal and cause electric shock or fire.
Exclusive circuit breaker (MCCB, ELB) must be installed to the power supply.
XWhen overcurrent or current leakage occurs with no circuit breaker installed, power will not be cut-off and it may cause
electric shock or fire.
XDo not use damaged parts. It may cause fire or electric shock.
You must cut-off the power before you work on, or adjust any power supply part for product installation, maintenance,
repair or any other services.
XThere is risk of electric shock.
XEven when the power is off, it is dangerous when you come in contact with inverter PCB, fan PCB since high pressure DC
voltage is charged to those parts.
XWhen replacing/repairing the PCB, cut-off the power and wait until the DC voltage is discharged before replacing/
repairing them. (Wait for more than 15 minutes to allow it to discharge naturally.)
If the refrigerant gas leaks during the installation, you should ventilate the room.
XWhen the refrigerant gas gets in contact with flammable substance, it may generate toxic gas.
Gas leakage must be checked after installation is completed.
XWhen the refrigerant gas gets in contact with flammable substance, it may generate toxic gas.
You can get a frostbite if you get in contact with the leaked refrigerant gas.

fPlace where hot discharge air or noise from the outdoor unit may not disturb the neighbor (Especially in residential areas,
keep the operation hours in mind.)
fPlace where structure can bear the weight and vibration of the outdoor unit.
fPlace with flat surface where rainwater does not settle or leak.
fPlace where it is not exposed to strong wind.
fWell ventilated place with sufficient service place for repairs and maintenance. (Discharge duct can be purchased
separately)
fPlace where you can connect the refrigerant pipes between indoor and outdoor units within allowable distance.
fPlace where it allows easy waterproofing and draining work for the condensation water generated from the outdoor unit
during heating operation.
fPlace where there is no risk of inflammable gas leakage.
fPlace where there is no direct influence of snow or rain.
fDo not install the product in a place where it will be directly exposed to sea breeze.
- Consult an installation expert (or company) since you will need to take extra anti-corrosion measures if you need to
install the product in a place where it can be exposed to direct sea breeze. (You have to remove dusts and salinity on
the heat exchanger and apply designated rust inhibitor more than once a year.)

Selecting installation location
CAUTION
20
• System air conditioner may cause static noise when listening to AM stations. Therefore, select an installation
location for indoor unit where electrical wiring can be done while keeping certain distance from a radio,
computer and stereo equipment.
- Especially, keep the unit at least 3m away from the electrical equipment in an area with weak electromagnetic
waves and put the main power cable and communication cables in a separately installed protection tube.
- Make sure that there is no equipment that generates electromagnetic waves. If not electromagnetic waves
may cause problem to the control systems which may lead to air conditioner malfunction. (Example: Remote
control sensor of the indoor unit may not receive the signal very well, due to ballast stabilizer of the lighting
equipment.)
• In regions with heavy snowfall, make sure to install the outdoor unit where there is no concerns of direct
snowfall on the outdoor unit. Also, build higher base support so that accumulated snow does not block the air
inlet or the heat exchanger.
• R-410A refrigerant is a safe, nontoxic and nonflammable refrigerant. However, if the place holds any concerns for
exceeding dangerous level of refrigerant concentration in case of refrigerant leakage, extra ventilation system is
required.
• When you install the outdoor unit in a high places such as roof, install fence or guardrail around it. When there is
no fence or guardrail, service person could fall.
• Do not install the product in places where corrosive gases such as sulfur oxides, ammonia, and sulfurous gas are
produced. (e.g. Toilet outlet, ventilation opening, sewage works, dyeing complex, cattle shed, sulfuric hot spring,
nuclear power plant, ship etc.) When installing the product in those places, contact an installation specialty
store as the copper pipe and brazing part will need additional corrosion proof or anti-rust additive to prevent
corrosion.
• Make sure to keep any inflammable materials (such as wooden materials, oil etc.) around the outdoor unit. When
there's fire, those inflammable material will easily catch the fire and may pass it on to the product.
• Depending on the condition of power supply, unstable power or voltage any cause malfunction of the parts or
control system. (At the ship or places using power supply from electric generator...etc)
• Make sure to install MCU when using HR products.
• When you select the location to install MCU, the location is far away from indoor rooms because the refrigerant
running of MCU may create noise.

fSpace requirement was decided based on following conditions; Cooling mode, outdoor temperature of 35 °C. Larger
space is required if the outdoor temperature is higher than 35 °C or if the place is heated easily by quantity of solar
radiation.
fWhen you secure installation space, consider path for people and the direction of the wind.
fSecure installation space as shown in the below illustration, considering ventilation and the service space.
fIf the installation space is narrow, installer or other worker may get injured during work and may also cause problem to
the product.
fIf you install multiple number of outdoor units in one space, make sure to secure enough ventilation space if there’s
any walls around the product that may disturb the air flow. If enough ventilation space is not secured, product may
malfunction.
fYou may install the outdoor units with 20mm of space between the product, but product’s performance may decrease
depending on the installation environment.

1. Make sure that the height of the base ground is 200mm or higher to protect the outdoor unit from rain water or other
external conditions. Also, install a draining pit around the base ground and connect the drain pipe to the drainage.
2. Considering the vibration and weight of the outdoor unit, strength of the base ground must be strong to prevent noise
and the top surface of it should be flat.
3. Base ground should be 1.5 times larger than the bottom of the outdoor unit.
4. Outdoor unit must be fixed firmly so that it can withstand the wind speed of 30m/s. If you cannot fix the outdoor unit on
the base ground, fix it by side or use extra structure.
5. In heating operation, defrost water may form so you must really care about the drainage and waterproofing the floor. To
prevent defrost water from stagnating or freezing, construct a drainage with over 1/50 slope. (Ice may form on the floor
in winter time.)
6. It is necessary to add wire mesh or steel bar during concrete construction for the base ground to prevent damages or
cracks.
7. When installing multiple outdoor units at the same place, construct a H beam or an anti-vibration frame on the base
ground to install the outdoor unit.
8. After installing a H beam or an anti-vibration frame, apply corrosion protection and other necessary coating.
9. When concrete construction for outdoor unit installation is completed, install an anti-vibration pad (t=20mm or more) or
an anti-vibration frame to prevent vibration of the outdoor unit from transferring to the base ground.
10. Place the outdoor unit on a H beam or an anti-vibration frame and fix it with the bolt, nut and washer. (The bearing force
has to be over 3.5kN)

Refrigerant pipe installation
WARNING
• When installing, make sure there is no leakage. When collecting the refrigerant, stop the compressor first before
removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works
with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle
abnormally high which may lead to explosion and injury.
ENGLISH
Refrigerant pipe work
fThe length of refrigerant pipe should be as short as possible and the height difference between an indoor and outdoor
unit should be minimized.
fPiping work must be done within allowable piping length, height difference, and the allowable length after branching.
fThe pressure of the R-410A is high. Use only certified refrigerant pipe and follow the installation method.
fAfter installing the pipes, calculate the total length of the pipe to check if additional refrigerant is needed. When you need
to charge the additional refrigerant, make sure to use R-410A refrigerant.
fUse clean refrigerant pipe and there shouldn’t be any harmful ion, oxide, dust, iron content or moisture inside pipe.
fUse tools and accessories that fit on R-410A only.

fIf AHU kit is included among the indoor units, you must add 0.063kg of refrigerant for every 1kW of the AHU capacity
increase.
Note1) In case the capacity conjunction of the Hydro Unit HT exceeds 50 % among the total indoor unit, please don’t put the
additional refrigerant.
fMethod to calculate total amount of additional refrigerant
- Amount of additional refrigerant depending on the pipe length (ⓐ)
- Amount of additional refrigerant for each indoor unit (ⓑ) = ∑(Amount of additional refrigerant for each connected
indoor unit) ❇ Refer to the table
- Total amount of additional refrigerant = ⓐ+ⓑ
❇ Sum of total amount of additional refrigerant and the basic amount of refrigerant should not exceed 100kg. If the
refrigerant exceeds 100kg, separate the module so that weight of the refrigerant doesn't exceed 100kg.
Ex.) For AM200FXVAG✴, basic amount of refrigerant is 8.4kg, therefore total amount of additional refrigerant (ⓐ+ⓑ)
should not exceed 91.6 kg.

Important information for refrigerant pipe work
• Make sure there is no moisture inside the pipe.
• Make sure there are no foreign substances and impurities in the pipe.
• Make sure there is no leakage.
• Make sure to follow the instruction when welding or storing the pipe.
Nitrogen flushing welding
fWhen welding the refrigerant pipes, flush them with nitrogen gas as shown in the picture.
fIf you do not perform nitrogen flushing when welding the pipes, oxide may form inside the pipe. It can cause the
damage of the important parts such as compressor and valves etc.
fAdjust the flow rate of the nitrogen flushing with a pressure regulator to maintain 0.05m2/h or less.

Apply pressure to the liquid side pipe and gas side pipe
(when installing outdoor units in module) with Nitrogen
gas at 4.1MPa.
If you apply pressure at more than 4.1MPa, pipes may get
damaged. Apply pressure with pressure regulator and pay
attention to the pressure of the nitrogen.
Keep it for minimum 24 hours to check if pressure drops.
After applying Nitrogen gas, check there's any change of
pressure, using a pressure regulator.
If the pressure drops, check for gas leakage.
If the pressure is changed, apply soap water to check for leakage
and check the pressure of the nitrogen gas again.
Maintain 1.0MPa of the pressure before performing
vacuum drying and check for further gas leakage.
After checking the first gas leakage, maintain 1.0MPa to check for
further gas leakage.
CAUTION
80
• Perform a Nitrogen gas leak test with the service valve of the outdoor unit closed.
• When charging the nitrogen gas, charge it from the both (high•low pressure) sides.
• If the pipe is filled in a short time with a highly excessive pressure of Nitrogen gas, the pipes may get damaged.
Make sure to use a regulator to prevent the high pressure Nitrogen gas, over 4.1MPa, from entering into the pipe.
Vacuum drying pipes and indoor units
Connect the manifold gauge to the liquid side pipe
and gas side pipe (when installing outdoor units in
module).
When installing outdoor units in module, connect the manifold gauge to
liquid side pipe and the gas side pipe.
Perform vacuum drying of the liquid side pipe and
gas side pipe (when installing outdoor units in
module) using a vacuum pump.
Make sure that check valve is installed to prevent pump oil from flowing
into the pipe.
While the vacuum gauge pressure is less than
-100.7 kPa (5 Torr), perform the vacuum drying for
more than 1 hour and close the valve.
Vacuum pressure must be checked with the vacuum gauge.
After vacuum pump stops, check whether the
pressure is maintained within -100.7 kPa (5 Torr) for
an hour.
Check for gas leakage

❇ During "Discharge mode of DC link voltage", voltage of INV1 and INV2 will be displayed alternately.
❇ Even when the outdoor unit power is off, it is dangerous when you come in contact with inverter PCB and fan PCB since
they are charged with high DC voltage.
❇ When pressing K2 key 9 to 12 times without inverter checker, error code can be displayed on segment even though the
outdoor unit is normal.
❇ When replacing/repairing the PCB, cut-off the power and wait until the DC voltage is discharged before replacing/
repairing them. (Wait for more than 15 minutes to allow it to discharge naturally.)
❇ When there were error, 'Discharge mode of DC link voltage' may not have been effective. Especially if error E464 and E364
have been occurred, power element might be damaged by fire and therefore, do not use the 'Discharge mode of DC link
voltage'.

1. Turn on both the indoor unit and the remote control.
2. Enter the “Option setting mode” on the remote control.
3. Set the address of each MCU port that is connected to an indoor unit by referring to the following table. (You can also set
the address of each indoor unit.)
Setting the MCU and Pipe Addresses (for HR Only)
Setting the Pipe Addresses Automatically (Auto pipe pairing operation)
You can use the Automatic pipe-address setting operation to automatically set the address of each MCU port that is
connected to an indoor unit.
If an MCU port is set incorrectly or a pipe between an MCU and an indoor unit is connected incorrectly, that indoor unit is
indicated.
Check items before running the Auto pipe pairing operation
Outdoor Temperature (°C)
1. Ensure that the service valve of the outdoor unit is open.
2. Ensure that the power cables and communication cables of the indoor and outdoor units are correctly connected.
3. Turn on the indoor and outdoor units 6 hours before running the Automatic pipe-address setting operation to warm up
both units sufficiently.
4. Before turning on the power, check whether the voltages and phases are correct by using a voltmeter and a phase tester.
- Check for the R, S, T, and N terminals: ensure that 380-415V is read between lines (R-S, S-T, T-R) and 200-240V (R-N, S-N,
T-N) between phases.
5. After the power is turn on, set the devices (indoor unit, MCU, and others) that are connected to the outdoor unit, and set
the options.
Note that, before the MCU port addresses are set, MCU port setting errors (E216, 217, 218) may occur. You can run the
Automatic pipe-address setting operation regardless of MCU port setting errors.
6. Especially if error E464 and E364 have been occurred, power element might be damaged by fire and therefore, do not use
the 'Discharge mode of DC link voltage'.
7. Check the operating temperature for the Automatic pipe-address setting operation:
If this operation is run at a temperature out of the operating temperature range, the addresses set automatically may be
incorrect. Set the pipe addresses manually by referring to Setting the Pipe Addresses Manually.
8. Auto pipe-pairing operation does not work within 3 minutes after power on and reset due to communication check.
