Simple Maintenance Procedures.
Cleaning The Electronic Cells
For peak efficiency, the Electronic Cells in your Air Cleaner should be washed regularly (between one and six months). This is necessary to remove the deposits of dirt particles collected while running. Experience will be the best indicator of how often the cells should be washed.
Removing The Electronic Cells And Pre-filter
!CAUTION To reduce the risk of electrical shock, disconnect power to the Air Cleaner before perform- ing maintenance or service.
1.At the thermostat, place the system switch to OFF and the fan switch to AUTO to assure that the air system will not turn on while cleaning.
2.Push the Electronic Air Cleaner power switch to the “OFF” position. Unplug power cord at the wall before removing the Electronic Cells. If you are not familiar with this equipment, contact your installer or dealer.
!CAUTION High voltage is
present within the air cleaner for operation. Before removing the power door, wait at least 15 sec- onds to allow the power pack and electronic cells to discharge.
3.Turn the latches on the power door 1/4 turn (open position) to unlock and remove the power door.
4.Remove the
5.Slide the Electronic Cells out.
Soaking
The dirt on the Electronic Cells can be removed by soaking in a strong solution of dishwasher detergent.
1.Use a container large enough to hold the Electronic Cells, such as a large plastic dishpan, trash container, or laundry tub.
2.Use an automatic dishwasher deter- gent in hot water. All major brands worked well in tests.
NOTE: Depending on the minerals in the water in your area, some brands of dishwasher detergent may form a precipitate of scum. If a noticeable scum floats to the surface, try another brand of detergent.
3.Pour into the container about 3/4 cup of detergent per cell. A bit more if the container is much larger than the cell. Pour in enough very hot water to cover the cells.

4.After the detergent has completely dissolved, put the cells in to soak.
5.Soak the cells and
!CAUTION Be careful not to scald hands and arms when using very hot water.
6.Rinse the cells and
7.Soak the cells (only) in clean hot water for another 5 to 15 minutes.
8.Remove the cells and let drain for 15 to 20 minutes. If the water draining from the cells feels slippery, the cells need more rinsing.
9.Inspect the cells for cleanliness. If any dirt remains, repeat the washing procedure until clean.
10.Replace the cells and
NOTE: If washing must be repeated, this is an indication that washing should be performed more frequently.
Replacing The Electronic Cells And Pre-filter
NOTE: A guide key in the Air Cleaner cabinet will allow the Electronic Cells to fit into the cabinet in only one position - with the arrow pointing in the direction of airflow.
1.Position cells correctly and slide them into place.
2.Insert the
3.Replace the power door. Turn the latches 1/4 turn to secure the door.
4.Restore all power previously discon- nected - See Item #2 under Removing
The Electronic Cells And
5.Push the Electronic Air Cleaner switch to the “ON” position.
Cleaning The Air Flow Switch
During normal maintenance, the air flow sensor tube may require cleaning to remove any accumulated dirt and dust.
To clean the tube, gently push a soft pipe cleaner into the tube above and below the printed circuit board. Gently blow into the tube to remove loosened dirt.
Clean above and below circuit board in
air flow tube.
Cleaning the Ionizing Wires
Ionizing wires may become coated causing loss of cleaning ability by the collecting cell and should be cleaned, at least, annually.
The thin ionizing wires are sharp and fragile. Use care when wiping the wires with the pencil eraser to avoid personal injury or broken wires. If an Ionizing wire breaks, refer to “Replacing An Ionizing Wire”.
Using a pencil eraser, wipe each ionizing wire, exercising care to avoid damage to them.
