SAFETY INFORMATION
The following safety precautions must be taken when installing the unit.
Be aware that AHU-KIT has to be combined with DVM S Series outdoor unit only.
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.)
WARNING CAUTION
Risk of death or serious personal injury. Potential risk of personal injury or material
damage.
CAUTION
Turn off the power before installation,
service, and cleaning.
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.
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.
Use the pipe or flare part for R410A
refrigerant only.
If the power cable or cord is damaged, the
manufacturer, a qualified service technician
must replace it to avoid a potential risk.
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 .
Manufacturer is not responsible for
accidents due to incorrect installation by
unqualified person.
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.
When there were leakage during installation,
you must ventilate the area.
Toxic gas may generate when refrigerant gas
contacts with fire.
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.

SAFETY INFORMATION (Continued)
CAUTION
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
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.
shock or fire.
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.
Make sure there is no leakage after installation.
Toxic gas may generate when refrigerant gas contacts with fire.
WARNING
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.
Do not install the AHU-KIT 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 sunlight, rain, outdoor humidity, dust and temperature.
The manufacturer is not responsible for the damage occurred by not keeping standard of the installation.

INSTALLATION (Continued)
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 - 240 V(208 - 230 V for US) 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 05 series installation option SEG21(Refer to page 26) 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 10).
• F3, F4(Refer to page 10) is communication line for wired remote controller(12 V).

• Simple BMS can control Room temperature or Discharge temperature by setting SEG17 of 5 series Installation option.
- For controlling Room temperature : SEG17 of 5 series Installation option → 0
- For controlling Discharge temperature : SEG17 of 5 series Installation option → 1
• Discharge temperature can be set by DMS.
• Simple BMS control is not influenced by DMS’s restrictions on operation mode, set temperature or remote controller usage.
• If you want to set Room temperature or Discharge temperature by using Simple BMS, setting Buzzer control option as
“Disuse buzzer” is recommended.

• 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.
