Inspection and trial operation

Measure to take when E503 error occurs

Perform Trial Operation (cooling/heating)
- See the instructions on Key operation modes.

Perform Auto Trial Operation again

Yes

Yes

Yes

Yes

Yes

Take corrective measures.

No.

Is the ball valve on the outdoor unit

opened?

Take corrective measures.

No.

Has the correct amount of additional refrigerant

been injected into the indoor unit and liquid line?

Take corrective measures.

No.

Are the 4-way valve, Main EEV and

pressure sensors operating properly?

Take corrective measures.

No.

Is the operation cycle normal?

※

Symptoms for abnormal operation of the 4way valve

– Abnormal noise during compressor operation, Increase in the suction temperature.

※

Symptoms for abnormal operation of the Main EEV

– It is not possible to control the superheat (SH)

– It is not possible to secure a DSH of higher than 20K

※

For more information, see the troubleshooting in the service manual.

CAUTION

• If service valve (ball valve) check is required, corresponding outdoor unit will display the error.
• If service valve (ball valve) check is required, auto detection mode will be terminated. Check service valve (ball valve) of gas pipe and

liquid pipe at the same time when checking service valve (ball valve).

• When 4way valve, Main EEV detection is needed, run heating trial operation for more than 1 hour and analyze the data to check for a problem.
• If there's frost formed in outdoor unit or the outdoor unit is operating in defrost operation, it may be hard to detect problem normally.

In this case, perform Trial operation or Forced defrost operation to eliminate the frost, and then perform Auto Trial Operation again.

• If the operation range is not within guaranteed range, error may occur even though the product is normal.
• To replace a component or inspect the PBA, be sure to cut off the power supply first. If inspection must be performed with the power

supply on, exercise extra care to prevent electric shock.
