6.1 General Check
CAUTION
·
When clamping the wiring, use the included clamping material to prevent external pressure being exerted on
the wiring connections and clamp firmly.
·
While performing wiring work, make sure the wiring is proper and does not cause the control box lid to
stick up, then close the cover firmly. When attaching the control lid, make sure you do not pinch any wires.
·
Outside the indoor unit and outdoor unit, separate the weak wiring (remote controller and transmission wiring)
and strong wiring (ground and power supply wiring) at least 2 in. (50mm) so that they do not pass through the
same place together. Proximity may cause electrical interference malfunction and breakage.

result in accident or electric shock.
