Sooner or later you will have an inspector ding you on a indoor unit disconnects switch for a mini split. Though not necessarily need it, code officials will be requiring it sooner or later and more and more jurisdictions. We offer a three-pole disconnect switch that would mount into a box and the switch needs to be within reach of the indoor head for safety purposes. Our part number is a K3PST. This will break wires one two and three between the indoor and outdoor units.
