Safety Information
The following safety precautions must be taken when installing the unit.
Be aware that AHU-KIT has to be combined with
“AC026MXADKH/EU, AC035MXADKH/EU, AC052MXADKH/EU, AC071MXADKH/EU, AC100MXADKH/EU,
AC100MXADNH/EU, AC120MXADKH/EU, AC120MXADNH/EU, AC140MXADKH/EU, AC140MXADNH/EU,
AC180JXAPNH/EU, AC200KXAPNH /EU, AC250KXAPNH/EU” outdoor unit only.
Risk of death or serious personal injury. Potential risk of personal injury or material damage.
Use R410A refrigerant.
● When using R410A, moisture or foreign substances may affect the capacity and reliability of the product. Safety
precautions must be taken when installing the refrigerant pipe.
● R410A is a quasi-azeotrope of two refrigerants. Make sure to charge liquid one when adding refrigerant.
(If you charge gaseous refrigerant, it may affect the capacity and reliability of the product as a result of change
in formation of the refrigerant.)
Turn off the power before installation, service, and
cleaning.
The installation must be done by the manufacturer
or its service agent or a similar qualified person in
order to avoid a hazard.
● Installation by an unqualified person may cause a
water leakage, electric shock or fire .
Use only rated parts and tools.
● If you don’t use the rated parts and tools, it can
cause trouble with the product and bring about
injury.
When adding the refrigerant, use the R410A
refrigerant only.
● If any gas or impurities except R410A refrigerant
come into the refrigerant pipe, serious problem
may occur and it may cause injury.
Install the outdoor unit correctly according to the
installation manual.
● An incorrect installation may cause a water
leakage, electric shock or fire and so on.
Manufacturer is not responsible for accidents due to
incorrect installation by unqualified person.
Use the pipe or flare part for R410A refrigerant only. When there were leakage during installation, you
must ventilate the area.
● Toxic gas may generate when refrigerant gas
contacts with fire.
If the power cable or cord is damaged, the
manufacturer, a qualified service technician must
replace it to avoid a potential risk.
The electric work must be done by service agent or
similarly qualified persons according to national
wiring regulations and use only rated cable.
● If the capacity of the power cable is insufficient or
electric work is not properly completed, electric
shock or fire may occur.
CAUTION

English
Preparation
Arrange the cables between the AHU-KIT and
outdoor unit after connecting.
Attach the cover securely so that the electrical
component box cover does not get loosen.
● If the cover is attached incompletely, it can cause
trouble with a heat generation, electric shock or
fire of the terminal board.
Install designated ELB for AHU when installing the
power cable.
● If you do not install designated ELB for AHU,
electric shock or fire may occur.
Use the copper wire for the power cable
and use only rated cables and parts.
Make sure electrical circuit is correctly connected.
● Overheating may cause fire.
Install the cables with supplied cables firmly. Fix
them securely so that external force is not exerted
to the terminal board.
● If the connection or fixing is incomplete, it can
cause trouble with a heat generation, electric
shock or fire.
Make sure that the power for AHU-KIT is under
maximum, and over minimum voltage allowed.
● It may cause electrical component malfunction
which can damage the product.
Make sure there is no leakage after installation.
● Toxic gas may generate when refrigerant gas contacts with fire.
Make sure of a earthing.
● Do not connect the earth wire to the gas pipe,
water pipe, lighting rod or telephone wire.
● If earthing is incomplete, electric shock or fire
may occur.
Follow the instructions in this manual to make
sure that the condensed water dripping from
the drain hose runs out properly and insulate
the drain pipe so that dew condensate does not
generate.
● Household goods may get wet if the drain pipe is
not properly installed.
Install the power cable and communication cable of the AHU-KIT at least 1m away from electric
appliances.
● Noise may heard depending on the electric wave though the cables are installed away from electric
appliances.
● Keep the space in front of AHU-KIT for maintenance.
Safety Information

English
Preparation
Do not install the AHU-KIT in following places.
● T he place where there is mineral oil or arsenic acid.
- There is a chance that parts may get damaged due to burned resin.
● The place where corrosive gas such as sulfurous acid gas generates from the vent pipe or air outlet.
- The copper pipe or connection pipe may corrode and refrigerant may leak.
● The place where there is a machine that generates electromagnetic waves.
- The air conditioner may not operate normally due to control system.
● The place where there is a danger of existing combustible gas, thinner or gasoline is handled.
- The place where carbon fiber or flammable dust is.
● The place where like spa and shore.
● The place with direct contact of sunlight, rain, outdoor humidity, dust and temperature.
 The manufacturer is not responsible for the damage occurred by not keeping standard of the installation.

• Terminal block 3, 4 (Refer to page 11) is for AHU-KIT control to receive the fan operation status. This input signal
should be simple OPEN/SHORT signal without any extra voltage.
- Normal fan operation : Terminal block 3, 4 is in SHORT.
- Fan is not in operation : Terminal block 3, 4 is in OPEN.
- To use fan feedback to protect your system, set the 05 series installation option SEG21(Refer to page 28) to “1”.
• Connect 220 - 240 V, 50 / 60 Hz (208 - 230 V, 60 Hz for US) to terminal block 1(L)/2(N).
• You should connect outdoor unit communication cable to communication line (F1, F2)(Refer to page 11).
• F3, F4(Refer to page 11) is communication line for wired remote controller(12 V).

• Keep the power supply of Simple BMS in 10 V ± 0.2 V.
• If the Simple BMS uses variable resistor(VR), make the electric resistance of VR under 1㏀.
• Simple BMS which uses variable resistor(VR) need to be connected to the AHU-KIT with 1:1 link.
• Use the Simple BMS which outputs voltage so that one Simple BMS controls several AHU-KIT at the same time.

• Consider power usage of the AHU when installing the ELB.
• Connect F3, F4 on AHU-KIT to the communication line (F3, F4) on wired remote controller. (Refer to page 17)
• Use the appropriate tools for wiring and make sure to connect them tightly within the tightening torque to
withstand the external pressure. Arrange the wires so that cover
or other parts does not get loose. They may cause overheating, electric shock or fire.
• Connect the power cable to the ELB.

Brazing the Pipe
• Make sure that there is no moisture inside the pipe.
• Make sure that there are no foreign materials and impurities in the pipe.
• Make sure that there is no leak.
• Be sure to follow the instruction when brazing the pipe.
1) Use Nitrogen gas when brazing the pipes as shown
in the picture.
2) If you do not use Nitrogen gas when brazing the
pipes, oxide may form inside the pipe. It can cause
the damage of the compressor, valves.
3) Adjust the flow rate of the Nitrogen gas with a
pressure regulatorto maintain 0.05m3/h or less.

Sensor Installation
1) EVA IN sensor should be attached after the distributor, on the coldest part of the heat exchanger pipe.
2) EVA Out sensor should be attached on the middle of inlet and outlet ports.
3) EVA IN/OUT sensor should be insulated for optimized system performance.
4) Room temperature sensor should be basically installed where room air enters(A), It could be also installed at the supplay air
side(B), especiallywith outdoorfresh air conditioning application.
In that case, installation option 05 series SEG15 and SEG16 function setting should be considered. (Refer to page 28)
• Please check sensor usage in label.
