1. What is a single refrigeration system
• A single refrigeration system is one that can have multiple outdoor units on one
refrigerant pipe work circuit.
• There are 2 types of EEV-KIT systems that can be built into the single refrigeration
system.
• System A : one EEV-KIT.
• System B : multiple EEV-KIT’s.
1.1 System A
This system has only one set of EEV-KIT built into one indoor unit with only one heat
exchanger. This system can be applied to an indoor unit whose capacity is up to
10HP.
• One EEV-KIT controls one EEV
• Maximum capacity is 10HP (equivalent to 280)
• Capacity setting of EEV-Control Box is required (default : 280)

• All wiring for the 5 sensors, EEV-coil, operation command to indoor fan motor, remote
control and Superlink line must be connected to the EEV-Control box.
• Check both return/supply air temperature sensors. (Thi-A,AF) whether the temperature is
detected correctly.
• Confirm whether the heat exchanger temperature sensors(Thi-R1,R2,R3) detect the
correct temperature. Incorrect mounting of any sensor will cause problems with the
compressors.
• Check during commissioning
• The overcurrent relay and magnetic contactor for the fan motor should be provided
locally.
• Check whether the anomaly signal can be detected or not by inputting the overcurrent
anomaly signal from the fan motor to the EEV- Control box.
• Power source to the fan motor should be provided independently and not from the EEV-
Control box.

• The remote control for the KXE6 system (RC-E5) shall be provided separately if
required.
• Central control (SC-SL4) can be use for controlling together with other indoor units.
• The limitations of the address settings, capacity selection and cable length of the
Superlink line are the same as the KXE6 systems.
(See technical manual of KXE6 for details.)
1.2 System B
• System B is a system that has multiple EEV-KIT’s built into one indoor unit with
multiple heat exchangers on one refrigerant circuit.
• This system can be applied up to 48HP for KXE6 AHU capacity.
• This system can be applied up to 60HP for KXZE1 AHU capacity.

• System B is a system that multiple EEV-KIT’s are built into one AHU and KXE6 or
KXZE1 outdoor units are used.
• However, multiple refrigeration systems used with one AHU can not be applied to system
B. In such cases, please use the master EEV-KIT for multiple refrigeration system
applications.

1. The wiring connection method for each EEV-KIT is basically the same as that for system A.
2. All of the return/supply air temperature sensors for all the EEV-KIT’s shall be placed and
connected individually.
3. The wiring for the fan motor command signal should be connected to one of the EEV-
Control boxes.
4. The remote control wiring shall be connected to all the EEV-Control boxes.
• The Superlink line must be connected to all EEV-Control boxes and the outdoor unit
according to the standard rules of the KXE6 system.
• Set an address for each EEV-Control box.

• Check the applicable models in the following tables.
• When controlling the AHU via a central control connected with normal indoor unit in
another refrigerant systems, it is recommend to connect the Superlink line to the central
control through Superlink adaptor (SC-ADNA-E) in order to control all EEV-KIT with
same settings and to prevent duplication of SL addresses.

Notes
（1）Take note that this control box is not waterproof.
Do not allow water or dust to enter the control box.
Mount the control box firmly using the four holes shown in the figure and
confirm that it will not come loose due to vibration.
Use the tie-wraps included in the control box to fix the wiring. Confirm that
there is no tension on the wiring to the terminal blocks and that the wiring
connections are fixed tight in the terminal blocks.
The label for the model name is located on the left side of the control box.
Take note that the wiring diagram is located on the back of the lid.
If you do not use the lid of the control box, then use the wiring diagram that
comes with the control box.
Ensure a gap of more than 15mm at the top of the control box to
remove the lid of the control box.
Always install this control box in a secure location inside a locked enclosure.
(As there is danger of electric shock or incorrect operation)
Provide the following clearances above, below, to the right and to the left to ensure
enough space for ventilation and service work of the control box.

When removing the sheet metal cover take care not to damage
the internal control box wiring.
After connecting the local wiring, confirm that there is no direct
tension of the local wiring onto the terminal blocks or the connectors
of printed circuit board (PCB).
If you are using the control box as shown in the figure,
take note the following points.
・
Ensure that the exposed high-temperature and the high-voltage parts
do not come into contact with any wiring.
・
Ensure that there is an air gap of more than 90mm above
the high-temperature and the high-voltage parts.
