Note

・ Do not shut down the power supply immediately after the stop of operation.

It should be waited for more than 5 minutes till the residual operation time of drain motor is counted up. Otherwise, it could cause water leakage or breakdown.

Advice

・ A message “Invalid request” may be displayed when a button is pushed. This is not a fault but it is because the button operation is set to

the “Disable”. (☞page 52)

・ The unit starts to operate initially with the following settings after the power on. These settings can be changed as desired. Central control …… OFF Operation mode …… With auto mode: Auto cooling …… Without auto mode: Cooling Set temp …… 23.0°C Fan speed …… 3-speed Flap direction …… When cooling: position 2, when heating: position 3 (☞page 10)

・ In the following cases, a message “Operation mode is invalid.” is displayed and it changes to the fan operation, because operation

modes are not matched.

① When Heating (including auto heating) is selected for Operation mode while using an OU for cooling only. ② When Heating is selected for Operation mode while controlling multiple units including units allowed for both cooling and heating and units

for cooling only.

③ When different operation modes are selected between IUs which are connected to a OU that do not allow mixed operation of cooling

and heating.

operation was started.

■Since the ﬂap is controlled automatically in the following operation, it may differ from the display on the R/C. 　∙ When the room temperature is higher than the set temp (In case of the heating operation) 　∙ When the “In operation for heating standby. ” or “In operation for defrosting.” is displayed (In case of the heating operation). 　 Cool air is blown horizontally not to blow directly to human body. 　∙ In a high humidity environment (during cooling operation)

■When you select Auto swing while the Anti draft setting (☞page 31) is enabled, the ﬂap will not swing and be set at ﬂap position

■Changing the left/right ﬂap direction and 3D auto ﬂow operation cannot be performed from the SC-SL2, SC-SL3, or SC-SL4. Also note that

3D auto ﬂow operation will not be disabled when you change the ﬂap direction from the SC-SL2, SC-SL3, or SC-SL4 during a 3D auto ﬂow operation.

Note

・ Do not manually move the ﬂaps or panel with anti draft by force. It could damage these ﬂaps and panels.

・ Do not blow air downward for a long period of time during the cooling operation. Condensation may be generated and water may drip from

the side panel. (In case of Ceiling suspended type)

・ For FDKs with a left/right ﬂap, it is recommended that the ﬂap should be set toward the right side when there is a wall on the left, or set

toward the left side when there is a wall on the right. For more information, refer to the Notes in the Individual ﬂap control section (☞page
