Air filter is used to filter out the dust from indoor, so it need to be cleaned every time. If the “air filter”, “air
exchanger filter” display on the remote controller, it means that the filter need to be cleaned.
If quantity of the dust is more than the acceptable level, air flow will be blocked, cooling capacity will decrease,
and noise level may increase. Normally when the device operates around 200 hours and above, the “air filter”
indication light will “on” and 1000 hours and above, “air exchanger filter” indication light will “on” depending
on the environment and using condition and pollution level.
It is not necessary to wait for “air filter” and “air exchanger filter” display to be “on”. If the filter is dirty, it should
be cleaned at once.
