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 hours.
Prefilter (#DM900-0855):
This must be replaced
every 3-6 months. A clean Prefilter will increase the
life of the HEPA Filter and improve airflow.
HEPA Filter (#DMH4-0400):
Replace every 2-4
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.
Replacing the UV Lamps, PCO Filter and Final
Filter
1. To change the PCO filter, Final filter and UV
lamps, turn the Air Cleaner
OFF
and
UNPLUG
it. Remove the screws from the lamp access
panel and remove the panel.
DO NOT
misplace
the parts.
2. Carefully remove the filters to avoid dusting of
filter. Dispose of the filters in a plastic bag and
discard with regular household trash.
3. To remove the lamp from the lamp socket, pull
the lamp, by the base, away from the lamp
socket. Remove the lamp from the support clip.
Remove the plastic lamp support clips by
pinching the back of the clip and lightly pulling
away from the reflector.
4. Before replacing the lamps, the reflector should
be cleaned with a soft cloth and mild non-
abrasive soap.
5. Replace the support clips by pressing them into
the hole in the reflector.
6.
NEVER
use any lamp other than from the
original manufacturer.
NEVER
run the Air
Cleaner with only one lamp.
7. When replacing the lamp, use gloves to prevent
oil from being deposited on the glass. Hold the
lamp by the base and slide the glass end into
the plastic support clip. Slide the lamp straight
into the lamp socket until the lamp locks into
place.
8. Remove the new PCO filter from the bag and
slide into the upper track under the lamps with
the fuzzy side towards the lamps. During
shipping and handling a small amount of white
dust is created. This can be cleaned by
vacuuming.
DO NOT
vacuum the filter.
