NOTES:￿

1.Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.￿ 2.Indoor and outdoor connecting wires are made with polarities,make wiring matching terminals.￿

3.Symbols used in wiring diagram above are, :Terminal block, , :connector, :PC board insertion tab.￿ 4.Emergency operation￿

￿ If a trouble occurs with either the remote controller or the indoor microcomputer and no other trouble exists,emergency operation for cooling can be ￿ performed by changing the setting of dip switch (SW3(I.B)) on the indoor controller board (emergency dry operation is not possible).
