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 respiratory protection while cleaning.
PRE-FILTER –
It is time to clean the PRE-FILTER when the red "PRE-
FILTER" light (shown in Figure 27) is illuminated.
20 Numbers in [brackets] are for 50 Hz international systems.
The air cleaner is factory set to notify the home owner
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/home owner to 1 month
[5 weeks] or 3 months [15 weeks] depending on the
conditions in the home (pets, smokers, etc.). Please
see "SET-UP MODE" (Page 13) to change the factory
settings.
1. Using a vacuum hose, vacuum in even strokes
across the length of the PRE-FILTER. After
vacuuming the entire PRE-FILTER using
even strokes going in one direction, repeat
the process using even strokes going in the
opposite direction as shown in Figure 31.
Figure 31 Vacuuming the Pre-filter
NOTE: Do NOT replace the plastic PRE-FILTER with
a metal type PRE-FILTER. A metal PRE-FILTER will
cause reduction in efficiency and potential failure of
the electronics 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 29). The air cleaner
is factory set to notify the home owner to clean the
COLLECTION CELLS every six months [31 weeks] of
actual run time of the air cleaner. This notification can
be changed by the installer/home owner 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 13)
to change the factory settings.
