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 0.75mm2(AWG18) as the communication lines between indoor
and outdoor unit, with their longest lengths of 50m (164feet). Please select the appropriate line
length as per the actual installation conditions. The communication lines can not be twisted
together. For the unit (≤30k), it‘s recommended to use 8m (26-1/4feet) long communication line.
④. Take 2 pieces of power cord of 0.75mm2(AWG18) as the communication lines between the wired
controller and the indoor unit, with their longest lengths of 30m (98-2/5feet). Please select the
appropriate line length as per the actual installation conditions. The communication lines can not
be twisted together. It‘s recommended to use 8m (26-1/4feet) long communication line.
⑤. The wire size of the communication line should be no less than 0.75mm2(AWG18). It‘s
recommended to take 0.75mm2(AWG18) power cords as the communication line.
