Before performing the setting, be sure to conducting necessary preparations.
1. Make sure that the operation of the outdoor unit has stopped (if it is still running, stop the oper-
ation), and turn off the power.
2. Remove the front panel of the outdoor unit.
3. Remove the lid of the electrical component box to expose the PCB.
4. Turn on the power of the outdoor unit. When the system is operated normally, the indicator
lamps may light as in following figure:
• Make sure that the POWER/MODE indicator lamp (LED101) is on and the ERROR indicator
lamp (LED102) is off.
• If there is a system error, the ERROR indicator lamp (LED102) flashes. Check the wiring and
power supply. After confirming the ERROR indicator lamp (LED102) has turned off, proceed
to the setting procedure.
