MAINTENANCE
CAUTION
Make sure to turn Air Cleaner OFF before
performing any maintenance or removing any
components.
For efficient operation, the filters must be changed on a
regular basis. If you notice a reduction in air flow from
the system, check the filters.
1. To access the filters, turn the Air Cleaner OFF at
the switch and remove the front door.
2. Carefully remove filters to avoid spilling of collected
contaminants. Dispose filters in a plastic bag and
discard with regular trash.
3. Remove plastic from new filters before installing.
Discard plastic safely. Take care not to damage the
filters.
4. Date the replacement filters in the space provided.
5. Ensure that the direction arrow on filter is pointing
toward the fan blade.
6. Use genuine replacement filters only. Call the
original installer for parts.
Note: When the filters are new, you may notice a new
smell from the system. This is normal and will dissipate
within a few days.
Carbon Prefilter (Part #W5-0810):
replaced every 3 - 6 months and may be vacuumed
between changes. Use a soft brush attachment when
cleaning.
True HEPA Filter (Part #W5-0860-3): Replace every
3-5 years. The life of this filter depends on the amount
of contaminants in the air and the frequency in which
the prefilter has been changed. Renovations in the
home that create wood, drywall dust or similar
contaminants will shorten the life expectancy of the
HEPA filter.
Note: Handle the HEPA filter by the frame only. The
paper is fragile and a puncture or tear will reduce
efficiency.
CAUTION
The new HEPA filter may be tight to install the first
time. Do not push from the center of filter. Apply
even pressure at both corners.
VOC After Filters: The 2 inch standard or heavy-duty
optional upgrade filters must be replaced every 6 - 12
months. If there are heavy odors in the home from
cooking, smoking, painting or other sources, the filter
may require changing more often.
Replacement VOC After Filters (2 inch):
Carbon Filter
Carbon/Potassium
Permanganate Filter
This must be
