Operating Instructions
Cleaning the unit’s filters
The internal filters are designed as secondary filters (there should be
extended surface filters cleaning the air before reaching the unit). However,
when unit filters are heavily soiled, wash or replace the filter material.
To wash: use vacuum cleaner to remove excess dust, then wash in warm
detergent treated water, keep filters flat or leave in frame to wash.
