Cautions when attaching or removing the board
When operating only the outdoor unit (cooling 40 Hz fixed mode) To make
only the outdoor unit run in cooling mode, short the places marked with
arrows below with an adaptor, and apply a voltage of 220 ~ 240 V AC to 1
and N on the terminal board.  (Avoid operating the outdoor unit alone for long periods of time.)
