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.
1. Isolate the device from the mains supply.
2. 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.
3. Remove the cell from the solution and rinse before soaking in clean water. Rinse again and repeat.
4. Carefully wipe ioniser wires  with a damp cloth.
5. 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 should be 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.
REPLACING THE CELL AND PREFILTER
Before replacing the cell it should be visually examined for bent or damaged collector plates or broken ioniser wires. Bent or
warped plates can be formed back into shape. This should be done to prevent the arcing sound which is caused by the plates
being too close together.
Do NOT use cells until broken ioniser wires are removed. If the broken wire is in the middle of the cell, replace with one of the
wires from either end. This will ensure the cell operates at reasonably high efficiency until a replacement is obtained from your
installer or service dealer.
When replacing the cell in the air cleaner make sure the airflow arrow on the cell is pointing downstream and the handle faces
outward. The cell is keyed  to prevent it being wrongly inserted. DO NOT USE EXCESSIVE FORCE if resistance is
encountered.
Slide the prefilter into the upstream prefilter guides.
Replace the access door and close firmly.
SERVICE CHECKS
Some faults can be checked without the need to call your service dealer.
If the snapping sound (arcing) occurs too frequently....The cell may be wet from washing. Turn the air cleaner off for two hours to
dry. Check the cell for broken ioniser wires or bent collector plates.
If the air cleaner switch is on but the light is not!...Check the system fan is ON. The airflow switch keeps the air cleaner OFF when
there is no air passing through the duct.
