◆ Remote control wiring and inter-unit wiring between indoor units
Do not allow the wire for the remote controller (communication wire) and the wire for AC220-240 V to come into
contact or put them together in one electrical conduit; otherwise, the control system may have trouble due to noise.
* Varies depending on the type of remote controller used.
