CAUTION
Use care when handling the electronic cells. The
metal edges can be sharp. Use of rubber gloves is
suggested during tub washing. The detergent is very
strong and the water should be hot. When washing
in a dishwasher, the cell may be hot if removed
during, or right after, the dry cycle.
WASHING THE ELECTRONIC CELLS
For optimum
performance, the electronic cells and
protective screen must be washed regularly to remove
the dirt cleaned from the air.
The required frequency of cell washing varies from
one installation to another, depending on a large number
of variables. In nearly all cases, the correct period is
between
one
and
six months.
Where infiltration and
internal generation of particulate contamination is light,
as in a smaller home occupied by 1 to 3 nonsmokers,
washing every five or six months may be adequate. With
a heavy dirt loading of cooking and tobacco smoke, dust,
and soot in the air, more
frequent
washing will be
required.
A home
with several active children, heavy
cooking and laundry,
and frequent entertaining may
cause
cells
to
load
and
require
washing
monthly.
If a very heavy buildup
of dirt is found on the
collector
plates, or the cell is still not clean after
washing, it should be washed more frequently. On the
other hand, if only light dirt loading is noticed, the
period between washings can probably be lengthened.
The WASH REMINDER SCHEDULE should be posted
in a convenient
place near the electronic air cleaner
where it will be seen regularly. Use it to record the
date on which the cells are washed and to establish
the correct schedule for cell washing.
The electronic cells and protective screen may be
washed in a number of different ways, depending on
homeowner
preference.
Perhaps the most convenient
way is in an automatic dishwasher. They may also be
washed manually by soaking, or with the hand sprayer
at a do-it-yourself, coin-operated car wash.
AUTOMATIC
DISHWASHER
The easiest and most convenient way to remove the
accumulated dirt from the electronic cells is to wash
them
in an
automatic
dishwasher.
The
dishwasher
automatically
provides
the
correct
cycle
of
wash,
rinse, and dry to clean the cell. The cell has been
designed
to withstand the high temperatures encoun-
tered in a dishwasher.
1. Take out the protective screen and remove
the
lint by using a vacuum
cleaner, rapping them on a
sheet of newspaper,
or spraying with a garden hose.
The protective screen may then be washed at the same
time as the electronic cells, if it will fit in the dish-
washer. The screen must be placed in the dishwasher,
so that it will not interfere with the washing of the
electronic cells.
NOTE:
The F52D prefilter screen may not fit in some
dishwashers.
If it does
not, wash
it as described
under MANUAL WASHING.
2. Place the electronic cells with the ionizer section
down (airflow arrows pointing up), on the lower rack of
the dishwasher.
IMPORTANT
Use care to avoid damage to the collector plates
when
placing
the
cells
in
the
dishwasher.
3. Use detergent in accordance with the dishwasher
manufacturer's instructions.
4. Allow the dishwasher to run through its complete
wash
cycle. You
may
also allow it to run
through
the complete dry cycle, although this is not necessary.
CAUTION
The electronic cell will be very hot at the end of
the dishwasher's cycle. Allow it to cool or wear
protective gloves when handling it. Hot water may
accumulate in the tubes supporting the collector
plates. Tip the cells so that these tubes will drain.
5. The electronic cells may be installed and energized
as soon as they are taken out of the dishwasher.
NOTE: The indicator light may not come on during the
normal
2 hour drying period. If annoying arcing
occurs during this period, the electronic air cleaner
may be switched OFF.
6. With some
dishwashers
it may be necessary to
rerun the complete cycle, or the rinse cycle, after the
cells are removed
if the homeowner
notices dirt or
residue inside the dishwasher.
NOTE: Washing the cell(s) more frequently or changing
to
a
different
dishwasher
detergent
may
reduce
residue.
MANUAL WASHING
The electronic
cells may
be washed
manually by
soaking
them
in a solution
of electric
dishwasher
detergent.
1. Provide
a suitable
container,
large enough
to
hold one or both of the cells. A large plastic dishpan,
trash container, or laundry tub works well.
2. Select
an
automatic
dishwasher
detergent that
dissolves readily in hot water. Tests have shown major
brands
such
as ALL,
FINISH,
and
ELECTRA
SOL
perform
very
well.
Depending
on
local water
con-
ditions, some brands may form a precipitate or scum.
If a noticeable scum floats to the surface, try another
brand.
The brand
that the homeowner
finds to give
best results in his electric dishwasher will probably give
best results in washing the electronic cells.
