Attention
Multiple wireless/infrared remote controllers cannot be used simultaneously for a single indoor unit.
Be careful not to connect cables to other terminals of indoor units (e.g. power source wiring terminal). Malfunction may occur.
Do not bundle together with the power source wiring or store in the same metal tube. Operation error may occur.
If noise is induced to the unit power supply, attach a noise filter.
