NOTE:
When RAS-7.0~12HNBRMQ1 outdoor units are connected with the RCIM-0.8FSN4 or RCD-0.8~1.0FSN3 or RCS-0.8~1.0FSN, if only
one of these indoor unit is operating in cooling mode, the minimum outdoor temperature is limited to 5ºC DB.
(d) Press “▲ ” or “ ▼ ”, select “LOUV.” and select “ ” (auto swing) by pressing “◄” or “►”.
The auto swing operation will start. Check the operating sound at the louvers.
If abnormal sound is generated from louvers, it may be caused by deformation of the air panel due to incorrect
installation. In this case, install the air panel again without deformation. If abnormal sound is not generated,
press “◄” or “►” again to stop the auto swing operation.
(e) Though the temperature detections by the thermistors are invalid, the protection devices are valid during the
test run. If an alarm occurs, refer to Table 7.2, Alarm Code and perform troubleshooting. Then perform the test
run again.
(f) To finish the test run, wait for 2 hours (as default setting) or press “
On/Off” switch again.
• Flashing the operation lamp for 2 seconds ON and 2 seconds OFF is for abnormality of the transmitting
between the indoor unit and the wired controller (loosened or disconnected connector, disconnected wires,
or incorrect wiring etc.)
• Small sound may be heard from the outdoor unit after turning ON the power source because the electrical
expansion valve is activated to adjust the opening. Therefore, there is no abnormality of the unit.
• Sound may be heard from the outdoor unit for seconds after running or stopping the compressor, starting
or finishing the defrosting, etc. It generates because of the pressure difference inside the piping from the
compressor. Therefore, there is no abnormality of the unit.
WARNING
!
Do NOT operate the air conditioners to check the electrical wiring, etc until the preparation of the test run is
completed.
