CAUTION
•
When clamping the wiring, use the included clamping material as shown in the Fig. 6.1 to prevent external pressure on the wiring connections, and
then clamp firmly.
• While performing wiring work, make sure that the wiring is proper and cannot cause the control box lid to stick up, then close the cover firmly. When
attaching the control lid, make sure that 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 50mm so that they do not pass through the same place together. Proximity may cause electrical interference malfunction
and breakage.
