Notes (1) The wire length covers values when necessary indoor units are connected in series with the unit power supply wire as shown below. Also, the wire
thickness and distance indicated above are for when voltage drop is 2%.
(2) These values are based on the conditions that indoor units are connected so that the total capacity becomes the mximum against each outdoor unit.
