External wiring procedure
- The power supply work is needed only to the outdoor unit. The power supply to the BD unit and the indoor unit is conduct-
ed through the transmission wiring. Therefore, the power supply work can be carried out at just one place of the outdoor
unit. It will contribute to simplify the work procedure and to save cost.
- Wiring cable size must comply with the applicable local and national code.
