F58G,H AND F58GUV SERIES COMMERCIAL DUCT MOUNTED ELECTRONIC AIR CLEANER
2. Using regular dishwashing detergent, allow the dish-
washer to run through the complete wash and rinse
cycle. Do not use the dry cycle. To avoid burns, let the
cells cool completely before removing, or wear pro-
tective gloves when removing the cells. Remember
that water may be accumulated inside the cells. Tip
the cells so the tubes can drain.
3. Wipe the ionizer wires and contact board on the end
of the cell using your thumb and forefinger with a
small, damp cloth.
4. Inspect the dishwasher. Rerun the wash and/or rinse
cycle with the dishwasher empty if there is dirt or res-
idue from washing the cells. If dirt or residue seems
excessive, wash the cells more often or try a different
detergent.
Washing Cells in Container
CAUTION
Hazardous Chemical.
Can cause personal injury.
Do not splash the detergent solution in eyes.
Wear rubber gloves to avoid prolonged contact with
detergent on skin.
Keep detergent and solution out of reach of
children.
NOTE: Always wash cells first before pre-filters to keep
heavy pre-filter lint from getting caught in cells.
1. Use large enough container to hold one or both cells.
2. Dissolve about 3/4 cup of automatic dishwasher
detergent per cell in enough hot water to cover the
cells. If detergent does not dissolve readily, or forms
scum on the water, try another brand, or use softened
water.
3. After detergent is completely dissolved, place cells in
container and let soak for approximately 15 minutes.
Agitate up and down a few times and remove. See
Fig. 10.

4. Wash the pre-filters following step 3. Empty and rinse
the wash container.
5. Rinse the cells and pre-filters 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 pre-
filters no longer feels slippery.
6. Soak cells and pre-filters in a final clear water rinse
for ten minutes.
7. Wipe the ionizer wires and contact board on the end
of the cell using your thumb and forefinger with a
small, damp cloth.
8. Make sure to dry the cells before inserting back into
the air cleaner.
Reinstalling Cells and Pre-filters
Insert the electronic cell with the contact board up and
the air flow arrow pointing downstream.
Tilt the cell toward you and insert the bottom of the cell
first.
Rotate the top of the cell back into position under the
spring contacts.
If the cell does not seat properly, check the orientation of
the airflow arrow on the cell.
Assemble the pre-filter to the front of the unit by first
inserting the lower portion of the pre-filter into the slot
at the bottom of the cabinet.
Rotate the pre-filter back into position. When properly
installed, the actuator on the pre-filter is inserted into
the wiring tray of the air cleaner.
Rotate the latch to secure the pre-filter in place.
The CHECK indicator may activate when the cells and pre-
filters are wet. To disable the CHECK indication, simply turn
off the air cleaner for two to three hours or until the cells
and pre-filters are dry.
Replacing Ionizer Wires
Broken or bent ionizer wires can cause an electrical short to
ground, often resulting in visible arcing or sparking. Do not
use cells until broken wires are removed. Cells can be used
temporarily with one wire missing, but replace the wire as
soon as possible.
Replacement wires are supplied cut to length with eyelets
on both ends for easy installation. To install:
1. Hook eyelet on one end of wire over spring connector
on one end of cell. See Fig. 11. Be careful to avoid
damaging spring connector or another cell part.
2. Hold opposite eyelet with needlenose pliers and
stretch wire the length of the cell. Depress the oppo-
site spring connector and hook the eyelet over it. See
Fig. 11
3. Check the cell for short circuits using an ohmmeter.
Check the resistance between cell frame and both the
ionizer and the collector contacts. Verify the resis-
tance is infinite for each. See Fig. 12.
