CLEANING THE ELECTROSTATIC CELL AND PREFILTER
The air cleaner is designed to be efficient over a wide range of cell loading conditions. However, as it cleans the air
the cell
and prefilter in your air cleaner become dirty. This can lead to reduced efficiency. To maintain the
air cleaner’s high operating efficiency it is essential to wash the cell and prefilter regularly.
Washing the Cell
CAUTION.
When washing the electrostatic cell care should be taken to avoid damage to the cell and injury to
yourself. The collecting plates and ioniser wires in particular must be handled with care.
Avoid prolonged skin contact with the detergent, and prevent injury to your hands, by wearing rubber
protective gloves during cell washing. Take care not to splash detergent solution in the eyes.
〈 Isolate the device from the mains supply.
〈 Open the access door and slide out the cell and prefilter screen.
Remove dirt from the cell by soaking in a solution of domestic dishwasher or similar alkaline based detergent for
15 to 20 minutes, agitating several times. (Note that some detergents recommend soaking for longer periods of
time.) Do not use acid based detergents as these will corrode the cell. Dilute detergent according to
manufacturer’s instructions.
DO NOT USE ADDITIVE INTENDED TO GIVE SPARKLE TO GLASSWARE IN DOMESTIC DISHWASHERS.
THIS WILL REDUCE THE EFFICIENCY OF THE ELECTROSTATIC CELL.
〈 Remove the cell from the solution and rinse before soaking in clean water. Rinse again and repeat.
〈 Carefully wipe ioniser wires with a damp cloth.
〈 Allow the cell time to dry completely - normally two hours. After cleaning the cell may occasionally look stained.
- If the stain is black or very dark, it is probably dirt residue. This can lower efficiency so the cell shouldbe
washed again.
- If the stain is white, it is probably detergent residue. This lowers efficiency and may also corrode the cell.
Rinse the cell again.
- If the stain is brown or yellow, it is probably tobacco smoke or other airborne dirt. Moderate discolouration of
this type does not affect the air cleaner efficiency. Recleaning is not necessary.
Washing the Prefilter
〈 Remove the accumulated dirt from the prefilter by vacuuming, brushing or washing. If washing in the same
detergent solution as the cells, wash ALL cells before washing the prefilter, otherwise the larger contaminants
from the prefilter will be picked up on the cell.
