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.
