Before starting operation
•Make sure that the power supply is turned ON before use.
•Start running after the “HO” display has disappeared. (max. 2 minutes)
•In some systems, more than one indoor unit may be connected to a single outdoor unit. When a remote controller for one indoor unit is used to change modes at the same time as a different indoor unit is working together with the outdoor unit, the operation underway stops, and the new operation begins. Until the old operation is complete, the display on the remote controller flashes to indicate that the new operation is in “waiting” status.
Warning:
Check and confirm the power circuit before use.
