2) When leakage region is found from service valve and piping connection re nut part : After the related
measures to check the refrigerant supplements and operation.
3) If the leakage region is pipe welding part : Weld leakage region after refrigerant gas release.(Brass parts
should only apply)
4) If the leakage region is surface area (Heat exchanger or pipe welding region is not) : Replace parts.
5) Check the PBA Relay
- Display of indoor unit : Ensure that the operating pilot lamp has been lighted.
- Ensure that the Relay input voltage of indoor unit PBA is normally.(If the PBA is defective, replace)

- Discharge temperature and the indoor
temperature measurements confirm
that the difference is more than 10
°C
- Fill up perfectly refrigerant after
re-vacuum.
[Execute the troubleshooting]
Check the refrigerant leaks.
Check the PCB Relay.
Does measurement
pressure include in ±10% extent
of reference pressure?
Connect the manifold gauge to the service
