Part 5 Field Settings and Test Operation
3.3 Test Operation Procedure
The procedure below describes the test operation of the complete system. This operation
checks and judges following items:
Check of wrong wiring (communication check with indoor units).
Check of the stop valves opening.
Judgment of piping length.
On top of this system test operation, indoor units operation should also be checked separately.
Make sure to carry out the system test operation after the first installation. Otherwise, the
error code
U3
will be displayed on the user interface and normal operation or individual
indoor unit test run cannot be carried out.
Abnormalities on indoor units cannot be checked for each unit separately. After the test
operation is finished, check the indoor units one by one by performing a normal operation
using the user interface. Refer to the indoor unit installation manual for more details
concerning the individual test run.
INFORMATION
It may take 10 minutes to achieve a uniform refrigerant state before the compressor starts.
During the test operation, the refrigerant running sound or the magnetic sound of a solenoid
valve may become loud and the display indication may change. These are not malfunctions.
1. Close all front panels in order to not let it be the cause of misjudgment (except the electrical
component box inspection opening service cover).
2. Make sure all field settings you want are set.
3. Turn ON the power to the outdoor unit and the connected indoor units.
4. Make sure the default (idle) situation is existing. Push BS2 for 5 seconds or more. The unit
will start test operation.
The test operation is automatically carried out, the outdoor unit display will indicate
t01
and the indication "Test operation" and "Under centralized control" will display on the
user interface of indoor units.
During the test operation, it is not possible to stop the unit operation from a user
interface. To abort the operation, press BS3. The unit will stop after ±30 seconds.
5. Check the test operation results on the outdoor unit segment display.
−
Normal completion: no indication on the segment display (idle)
−
Abnormal completion: indication of error code on the segment display
Take actions for correcting the abnormality. When the test operation is fully completed, normal
operation will be possible after 5 minutes.
Procedure
NOTICE
Be sure to turn on the power 6 hours before operation in order to protect the compressor.
Steps during the automatic system test run procedure:
