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.)
