9 FILTER REPLACEMENT/CLEANING
See fig. 8 on page 25
In order to open the inlet grid (i.e. access the filter components),
a narrow round screwdriver type tool will be needed (such as a
torx type). The inlet grid is secured by two mechanical clips. To
release these clips there are two access holes parallel to the
control board faceplate on the inlet grid (approx. 3½" from the
sides).
Insert the tool into the access holes and gently push further
through some light resistance. This will allow the clips to be
"unlocked" and thus the inlet grid will open easily.
DO NOT PULL THE DOOR OPEN WITHOUT RELEASING THE
CLIPS.
9.1 Prefilter replacement
The disposable prefilter can only be used once and cannot be
cleaned. Do not turn the prefilter around since it can only be
used in one flow direction.
9.2 Electronic filter cleaning
A crackling or snapping sound will be heard occasionally during
use of the air cleaner. This is normal and is caused by high
voltage arcing in the filter. Cleaning the electronic filter is
necessary when the crackling is heard frequently.
For maximum efficiency your air cleaner cell(s) should be
cleaned regularly. When cleaning is required the following
procedure should be used:
Cleaning the cell(s)
A Turn the air moving system OFF and disconnect the air
cleaner from power. Wait 15 seconds for the collecting
cell(s) to discharge.
B Remove the cell(s) and prefilter(s) from cabinet. Using a
solution of warm water and low sudsing detergent, soak
cell(s) for 20 to 30 minutes. Discard prefilter(s) and carbon
filter(s).
NOTE: Ionizing wires may become coated causing loss of
cleaning ability by the collecting cell. Using a damp cloth,
wipe each ionizing wire, exercising care not to damage
them.
CAUTION
CELLS MAY CONTAIN SHARP EDGES.
Use care when servicing unit or handling cells. Failure
to do so could result in minor personal injury.
