To operate the outdoor unit independently, short-circuit the sections indicated by arrows in the diagram below with an adapter, and apply rated VAC
between (L1) and (L2) on the terminal board of the outdoor unit. This allows the outdoor unit to be operated in cooling mode independently.
(Do not operate the outdoor unit in this condition for an extended period of time.)
L3
these pads are connected and Power is applied to L1 and L2 on terminal board.
n the outdoor unit operate in "TEST COOL 40Hz" mode.
