THE AIR FILTER

Caring for the air filter

The air filter should be cleaned about every 100 hours. If the lamp indicator and

temp indicator blink red simultaneously, or a message prompts you to clean the air

filter when you turn on the unit, the filter needs to be cleaned. (See "Related

Messages" ( ) and "Regarding the Indicator Lamps" ( ) for details.)
