① The fuse is located on the main board.
② Install the disconnect device with a contact gap of at least 3mm (1/8inch) in all poles nearby
the units (Both indoor unit and outdoor unit).The appliance must be positioned so that the
plug is accessible.
③ Take 2 pieces of power cord of 0.75mm
2
(AWG18) as the communication lines between
indoor and outdoor unit, with their longest lengths of 50m (164feet). Please select the
