The following safety precautions must be taken when installing the unit.
Be aware that AHU-KIT has to be combined with DVM Plus 3 or 4 Series outdoor unit only.
SAFETY INFORMATION
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.
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.
Do not install the air conditioner in following places.
 The 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 outdoor humidity, dust and temperature.
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.
 The manufacturer is not responsible for the damage occurred by not keeping standard of the installation.

Control-KIT Function
• Control-KIT uses EEV to control the amount of refrigerant flow and controls the system through outdoor unit and
wired remote controller.
• Control-KIT outputs the contact signal for AHU fan operation.
Terminal block 1, 2 (Refer to page 10) outputs the AHU fan ON contact signal (220~240V) for AHU when operating
in Cool/Heat/Fan mode. This contact signal output can not be used as power supply for the motor.
• Terminal block 3, 4 (Refer to page 10) 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 function switch K12(Refer to page 21) to OFF position.
• Connect 220~240V/50Hz to terminal block 1(L)/2(N).
• You should connect outdoor unit communication cable to communication line (F1, F2)(Refer to page 10).
• V1, V2(Refer to page 10) is power line for the wired remote controller(12V).
F3, F4(Refer to page 10) is communication line for wired remote controller.

• 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.

Connecting the Power Terminal
Connecting Power/Communication cable
• Turn off the power before connecting the power terminal.
• Maximum cable length and the amount of voltage drop for AHU power/communication cables should be under 10%.
• Consider power usage of the AHU when installing the ELB.
• Connect V1, V2 on AHU-KIT PBA to the power line (V1, V2) on wired remote controller.
Connect F3, F4 on AHU-KIT to the communication line (F3, F4) on wired remote controller. (Refer to page 14)
• 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 regulator to maintain 0.05m3/h or less.

Setting the Main Address
• Main address is the standard address for the communication between the
outdoor unit and the AHU-KIT.
• If the main address is not set up appropriately, communication error can
occur and the AHU-KIT may not operate.
• Use both SW01 and SW02 to set the main address from ‘00’ to ‘99’.
• Ensure that AHU-KIT does not have same address with any other indoor
units connected to the same outdoor unit.
