CARE AND MAINTENANCE
General care
Take good care of your unit to ensure that it delivers optimal
performance.
Vacuum the pre-filter occasionally to remove dust, or wash it
on a gentle, low temperature cycle in the washing machine.
Change the main filter every six months, depending on the
operating conditions.
When the unit is open to change the filter, vacuum any dust
that may have accumulated inside the unit.
Occasionally wipe the top of the unit with a dry dust cloth.
