Electronic Expansion Valve Kit Installation
Connection of refrigerant piping & Installation
1. Decide an installation place that can support the electronic expansion
valve kit.
2. Connect the “IN” refrigerant pipe to the outdoor unit.
3. Connect the “OUT” refrigerant pipe to each indoor unit (A, B and C).
The liquid and gas pipes should not be crossed when piping
connection.
4. Insulate the connection piping. A joint part of pipe needs double
thickness of insulation.
5. The expansion valve has to be installed that the user has no access to
it.

1. Connect the AC power cable and communication cable from the outdoor unit to terminal, then connect the cable to
another electronic expansion valve kit.
2. Connect the AC power cable and communication cable to each indoor unit (A, B and C).
3. Align the SW01/SW02, SW03/SW04 and SW05/SW06’s addresses with A, B and C indoor units’.

Function of Display
The numbers which is displayed on left are the status of indoor unit
checking status through communication with same outdoor unit. (If
it indicates 1, 3 and 7 that means the ADDRESS of indoor unit is set to
1, 3 and 7.)
The numbers which is displayed on right indicate the ADDRESS
of SW01/SW02, SW03/SW04 and SW05/SW06 in sequential. (If it
indicates 0, 1 and 2 that means the SW01/SW02 is set to 0, the SW03/
SW04 is set to 1, and the SW05/SW06 is set to 2.)
If the communication error occurs in distributor, the Er↔C0 message
will be shown on the display alternatively.
KEY function
If you press a KEY on the PCB, the display will show you a step of
appropriate electronic expansion valve.
