SECTION 5: MAINTENANCE
Cleaning the Filters
To maintain optimal operation, the filters in the
Two Speed Floor Air Filter should be checked
and cleaned or replaced regularly depending
on usage. We recommend checking the primary
filter and pre-filter once a month or more often
if usage is high. Always wear a respirator when
checking the filters.
To check, clean or replace the filters:
1. Disconnect power to the air filter.
2. Disengage the latches and swing open the
front door.
3. Remove the pre-filter, place it inside a trash
bag, and gently shake the dust from the fil

ter.
Use a respirator when
cleaning or changing fil
-
ters. Dust will become
airborne creating a respi
-
ratory hazard. For safe-
ty, run the air filter for
at least 6 minutes while
wearing the respirator
after cleaning.

maximize its filtering effect. DO NOT use
compressed air to clean the pre-filter, as it
may get damaged and lose its filtering capa
