TROUBLESHOOTING
NOTE: To avoid risk of electric shock, always
unplug the unit before cleaning.
1. Clean the outside of the unit with a soft,
damp cloth. The front grill can be cleaned
in soapy water after it has been removed
from the unit and the pre-filter has been
removed. See Figure 1.
NOTE: Ensure the grill is completely dry
before reinstalling it on the unit. Failure to do
so could cause damage to the filters or motor.
2. At least every 90 days, open the front grill,
remove the carbon pre-filter, and replace it.
This is necessary to maintain proper odor-
removing and overall filtration performance.
If necessary, it can be changed more
often. Remember to change the Pre-Filter
Calendar Dial to reflect the new
Pre-Filters installation to remove any plastic
wrapping that may be on the new filter
before you place it into the Air Purifier.
3. The HEPA filter should be removed every
12 months of use and matched to the
color indicator on the inside of the filter
compartment. When the filter matches the
dark, charcoal gray indicator, it should be
replaced. Your new HEPA filter will have an
arrow on the side to indicate air flow and
the direction the filter should be placed in
the unit.
NOTE: This unit will not operate unless the
grill is in the correct position.
