Electronic Air Cleaners
Step 5
Remove the Pre-Filter (Figure 11) and/or the Collec-
tion Cells (Figure 12) from the Air Cleaner.

Vacuum Cleaning

Vacuuming is the preferred method to clean the Pre-
Filter and Collection Cells. It is recommended that
the Pre-Filter and the Collection Cells be vacuumed
outside the home to ensure particles on the filters are
not reintroduced into the air. Persons highly sensitive
to the collected particles should wear appropriate res-
piratory protection while cleaning.

Pre-Filter

It is time to clean the Pre-Filter when the red "Pre-
Filter" light is illuminated.
The Air Cleaner is factory set to notify the homeowner
to clean the Pre-Filter every two months [10 weeks]
of actual run time of the Air Cleaner. This notification
can be changed by the installer/homeowner to 1 month
[5 weeks] or 3 months [15 weeks] depending on the
AC - A 22
conditions in the home (pets, smokers, etc.). Please
see "Set-Up Mode" (page A16) to change the factory
settings.
Step 1
Using a vacuum hose, vacuum in even strokes across
the entire Pre-Filter. Vacuum using even strokes in
one direction, then repeat the process using even
strokes in the opposite direction as demonstrated in
Figure 13 below.
Note: Do NOT replace the plastic Pre-Filter with a
metal type Pre-Filter. A metal Pre-Filter will cause re-
duction in efficiency and potential failure of the elec-
tronics in the Air Cleaner.

Collection Cells

The clean/dirty LED light bar indicator will illuminate
as the system cleans the air. The LED lights will
progress from green to yellow and then to red. When
the last red indicator is flashing, it is time to clean the
Collection Cells (see Figure 12). The Air Cleaner is
factory set to notify the homeowner to clean the Col-
lection Cells every six months [31 weeks] of actual
run time of the Air Cleaner. This notification can be
changed by the installer/homeowner to 2 months, 4
months, 6 months, or 9 months [10, 20, 31, or 46
weeks] depending on the conditions in the home (pets,
smokers, etc.). Please see "Set-Up Mode" (page A16)
to change the factory settings.
