Confirmation operation
Be sure to open the stop valves on the gas side/liquid side before starting operation.
• Be sure to carry out confirmation operation upon initial installation. If confirmation operation is not carried out, the
remote controller and the seven-segment display will display the error code
U3
, so that the unit cannot operate
normally. The air conditioner will go into normal operation 5 minutes after confirmation operation.
• Confirmation operation takes place automatically in cooling mode. The seven-segment display is shown in the
diagram below. and are displayed on the remote controller.
• During confirmation operation, operation cannot be stopped by the remote controller. To interrupt operation, press
the RETURN button (BS3), and residual operation will stop after 30 seconds.
• To balance the refrigerant, there will be about 5 minutes' waiting time before starting the compressor. In addition,
operation sounds will become louder (for example the blasting sound, the sound of refrigerant passing through the
system and the operation sound of the electromagnetic valve), but this is not a malfunction or abnormality.
• Individual abnormal indoor units cannot be verified. After confirmation operation, enter normal operation through
the remote controller, then check the indoor units one by one.
(1) Be sure to connect units to the power supply 6 hours before operation to protect the compressor.
(After connecting to the power supply, the units can be started once the seven-segment display lights turn off
(after 12 minutes, at most).)
Troubleshooting
(1) Check the error codes on the remote controller or the seven-segment display, and eliminate the errors.
(Refer to the installation manual/operation manual/service manual for error codes and troubleshooting)
(2) Press the RETURN button (BS3) after troubleshooting to clear error codes.
(3) Carry out confirmation operation again to make sure errors have been eliminated.
(If confirmation operation is not completed, the unit cannot operate normally)
(2) When not in operation, set to Normal mode .
(3) Press and hold the SET button (BS2) for 5 seconds or more to begin confirmation operation.
(4) Close all outer panels. (Misjudgments may occur if the outer panels are open)
(5) Operation will stop automatically after the unit has been operating for about 30 to 40 minutes; results of
confirmation operation are shown on the seven-segment display.
(Refer to the above table)
• Connect all units (indoor and outdoor units) to the power supply before operation. Operate units when all outer panels are closed.
• If this is not done before confirmation operation, the units cannot operate normally and confirmation operation cannot take place
correctly.
