NOTES
1 This wiring diagram is applied only to the outdoor unit.
2 When using the optional adapter, refer to the installation manual of the optional adapter.
3 For connection wiring to “to in/D unit F1-F2” or “to out/D unit F1-F2” refer to the installation manual.
4 How to use B1S~5, refer to “service precaution” label on el.compo.box (1) cover.
5 When operating, don’t shortcircuit the protection device (S1, 2PH).
