mounted in the control box.
•
If controlled by the centralized control equipment (the
central control panel (optional accessory)), the group NO.

control equipment.
10. TRIAL OPERATION
(1)
Confirm that the control box lid of the indoor units and the
outdoor unit are closed.
(2) Perform the test run according to the installation manual
attached to the outdoor unit.
• If the operation lamp on the control panel is flashing, it
indicates malfunction.
Check the error code of the liquid crystal display and
the malfunction source.
For the error code and the details, refer to the
operation manual attached to the indoor unit.
In particular, if an error in the
