17.3 About the system test run
NOTICE
Make sure to carry out the test run after the first
installation. Otherwise, the malfunction code will be
displayed on the user interface and normal operation or
individual indoor unit test run cannot be carried out.
The procedure below describes the test operation of the complete
system. This operation checks and judges following items:
▪ Check for incorrect wiring (communication check with indoor
unit(s)).
▪ Check of the stop valves opening.
▪ Judgement of piping length.
In case Hydrobox units or RA DX indoor units are present in the
system, the pipe length check will not be performed.
▪ 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 (e.g., Hydrobox) 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.
17.4 To perform a test run
1 Make sure all field settings you want are set; see "16.1Making
field settings"[428].
2 Turn ON the power to the outdoor unit and the connected

outdoor unit display will indicate " " and the indication "Test
operation" and "Under centralised control" will display on the
user interface of the indoor unit(s).
