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.

indoor unit. There are 4 types of situations:
(1) Clean Reminder is off (Timer zone shows “00“);
(2) Slight pollution: the former digit in timer zone shows 1 while the latter one shows 0, which
indicates the accumulated operating time is 5500hr. Each time the latter digit increases 1, the
accumulated operating time increases 500hr. When it reaches 9, it means the accumulated
operating time is 10000hr;
(3) Medium pollution: the former digit in timer zone shows 2 while the latter one shows 0, which
indicates the accumulated operating time is 1400hr. Each time the latter digit increases 1, the
