WARNINGS
Do not use any cleaning oil with volatile or harsh substance and metal brush while cleaning
the air filter as it will damage the surface of the air filter.
When performing cleaning work, please switch off all power supplies to avoid electric shock.
Always wear protective hand gears when performing cleaning to avoid personal injuries.
Always beware of objects below the feet and falling dirty particles when performing cleaning
at a high position from ground.

shape and damage its function.
MAINTENANCE OF THE HIGH EFFICIENCY COMBO FILTER
The “Filter Change Indicator” will indicate the need for the
change of air filter. Irregular service and maintenance of
the air filter will reduce the functionability of the air filter,
or lead to malfunction or even damage.
Set the frequency of the air filter maintenance according
to the usage capacity within the given environment. We
recommend a regular cleaning every 30 days, and a
replacement of the air filter every 180 days. If the usage
is heavy, the cleaning and replacement period can be
adjusted accordingly.
