1.3.4 Procedure for Inputting the Additional Refrigerant Charge Weight into
the PCB
Availability of the leak detection function feature requires input of the additional refrigerant
charge amount immediately after finishing the automatic charging. The input must be executed
before performing the test operation.
If a wrong value is input for the additional charged refrigerant weight, the accuracy of the leak
detection function will decrease.
Procedure
1. Close the electric box lid and all front panels except the one on the side of the electric box.
2. Press and hold the BS1 MODE button for 5 seconds to enter into setting mode 2.
3. Press the BS2 SET button 14 times.
4. The weighed and already recorded amount of additional refrigerant charge (not the total

Error code
Close valve A immediately and press the TEST OPERATION button once.
The operation will restart from the charging mode judgement onwards.
Close valve A immediately. Check following items:
- Check if the gas stop valve is opened correctly
- Check if the valve of the refrigerant cylinder is
opened
- Check if the air inlet and outlet of the indoor unit are
not obstructed
Error code
Charging is almost finished. Ready to close valve A.
Charging is finished. Close valve A and remove the refrigerant tank.
Close valve A and replace the empty cylinder.
After replacing the cylinder, open valve A again and continue the work (the outdoor
unit will not stop operating).
Close valve A immediately.
Restart the automatic charging procedure again.
Close valve A immediately. Check following items:
- Check if the high pressure/low pressure gas pipe,
suction gas pipe and liquid pipe stop valves are
opened correctly
- Check if the valve of the refrigerant cylinder is opened
- Check if the air inlet and outlet of the indoor unit are
not obstructed
Close valve A immediately. Confirm the malfunction
code by the remote controller and correct the
abnormality by following the " Correcting after
