4. Connect the power cords 1 and 2 accordingly to mains connection 1 and 2 (1, 2), accord-
ing to the installation example below (see below) and the connection diagram following it
and ensure that the ground connector is longer than the other cables in every case (c).

care to leave the ground connector longer than the other cables (c). Also ensure that
you connect conductors of the same cable colour to outdoor and indoor unit to the same
terminal number.
