Washing Cells in a ContainerCAUTION
Hazardous Chemical.
Can cause personal injury.
Do not splash detergent solution in eyes. Wear rubber
gloves to avoid prolonged detergent contact with skin.
Keep detergent and solution out of reach of children.
NOTE: Always wash the cells first, then the prefilters, to keep
heavy prefilter lint from getting caught in the cells.
1. Use a large enough container, such as a laundry tub or
trash container, to hold one or both cells.
NOTE: Sharp corners on cells can scratch surface of
bathtub.
2. Dissolve about 3/4 cup of automatic dishwasher deter-
gent per cell in enough hot water to cover the cells. If
detergent does not dissolve readily, or forms a scum on
the water, try another brand, or use softened water
3. After detergent has completely dissolved, place cells in
the container and let soak for 15 to 20 minutes. Agitate
up and down a few times and remove. See Fig. 13.

4. Next, wash the prefilters the same way. Empty and rinse
the wash container.
5. Rinse the cells and prefilters with a hard spray of very
hot water; rinse the tub clean, then fill the tub with clean
hot water and soak for 5 to 15 minutes. Rinse until the
water draining from the cells and prefilters no longer
feels slippery.
6. Soak cells and prefilters in a final clear water rinse for
ten minutes.
7. Wipe ionizer wires and contact board on end of cell using
your thumb and forefinger with a small, damp cloth.
Washing Cells at the Car WashUse the hand sprayer at a coin-operated do-it-yourself car
wash to clean the cells. Hold the nozzle at least two feet away
from the unit to avoid damage (such as broken ionizer wires or
bent collector plates) from the high pressure stream of water.
See Fig. 14. Follow the same sequence of wash and rinse as
recommended for cars. However, do not wax the cells. Be sure
to rinse until the water draining from the cells no longer feels
slippery.

Reinstall the Cells and Prefilters1. Inspect the cells for broken ionizer wires and bent collec-
tor plates. Repair as necessary or take to a
Honeywell Authorized Air Cleaner Repair Station.
2. Slide the prefilters into the upstream prefilter guides.
3. Slide in the air cleaner cells so the airflow arrow points
downstream and the handles faces outward.
4. Firmly close the access door.
5. Turn on the air cleaner. If the cells and prefilters are wet,
the neon light may not come on and you may hear
arcing. If the arcing is annoying, simply turn off the air
cleaner for two to three hours or until the cells are dry.
Replacing Media PostfiltersTo maximize the filtration efficiency of the media postfilters,
replace them every six months. Replacement filters are
available in the same size and configuration as the original
unit. Contact your local Honeywell distributor to purchase
replacement filters. Install the replacement filters exactly as the
filters provided with the equipment. Use the Service Reminder
Schedule at the end of this document to help you establish and
maintain a regular replacement schedule. Keep your Service
Reminder Schedule in a convenient location.
