When setting the filter clean reminder function, timer zone will display 2 digits, of which the former
indicates the pollution degree of operating place and the latter indicates the accumulated operating time
of 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
accumulated operating time increases 400hr. When it reaches 9, it means the accumulated
operating time is 5000hr.
(4) Heavy pollution: The former digit in timer zone shows 3 while the latter one shows 0, which
indicates the accumulated operating time is 100hr. Each time the latter digit increases 1, the
accumulated operating time increases 100hr. When it reaches 9, it means the accumulated
operating time is 1000hr.
The detailed pollution level and the corresponding time are as shown in Table 2-4-1 below:

clean reminder function. The icon will blink and press ▲ or ▼ button to adjust timer
zone to display “00”. In this case, the accumulated operating time will be cleared.
