Cleaning the Commercial
Electronic Air Cleaner
The F57 removes a variety of particulate contaminants from
the air. In the process of cleaning the air, the air cleaner
cells and prefilter become dirty, and the cleaning efficiency
is lowered.
To maintain a high standard of reliability and efficiency, it is
necessary to periodically maintain the F57. Maintenance
includes cleaning the cells and prefilter and inspecting the
F57. Service is required if the F57 is damaged, performs at
substandard efficiency, measures abnormal voltages, or
when the CHECK LED lights.
Regular cleaning with an alkaline-based detergent solution is
recommended. Use a commercial or home electric
dishwasher detergent, either liquid or powder. The wash
frequency is determined by the dirt level in the air. Actual
experience or optional WASH LED dictates the period
between cleanings.
If the optional WASH LED is connected and the WASH LED
comes on, a cell washing is overdue. Frequently wash the
cells and wipe any material buildup off the ionizer wires. This
prevents the wash led from coming on.
When washing with alkaline detergent results in excessive
buildup of collected dirt in the cells, do an extended cell
soaking. If buildup is still present, use high pressure water, or
air or steam cleaning. Some full-service distributors provide a
regular cleaning service to commercial establishments.
Opening the Grille
CAUTION
• Turn off power to the F57.
• Stand on a stable platform when working with the
F57.
The F57 grille can be opened by moving the spring clips
toward each other.
Removing the Heavy Duty
Commercial Cells and Prefilter
Remove the FC37B cells from the F57 as follows (Fig. 11):
• Turn off electrical power to the F57. Open the grille.
IMPORTANT
The cell swings down when unlatched.
• With one hand supporting the cell near the latch, rotate
the latch to an open position.
• Gently lower the cell with both hands until the cell contact
board is clear of the frame.
• Raise cell off hooks to free the cell.
Fig. 11. Removing the FC37B Heavy Duty
Commercial Cell (F57A model shown).
• Remove the prefilter from inside the grille.
• Remove the activated carbon filters, if used, only
if it must be replaced. The odor removal effectiveness is
reduced when the carbon is saturated with tobacco tar or
other gaseous contaminants and can require replacement.
Cleaning the Prefilter
• Shake out or vacuum the accumulated contaminants from
the prefilter. The prefilter can also be soaked in the
alkaline detergent solution, as described for cleaning cells
in the next section. When cleaning the prefilter, do not
soak in an acid detergent solution, or use high pressure
water, air or steam cleaning.
NOTE: When cleaning the prefilter, wash it after the cells
are washed. The lint residue from the prefilter
contaminates the wash water and can deposit inside
the cells. Dispose of the wash water.
Cleaning the Cells Using
Alkaline Base Detergent
WARNING
Hazardous Chemical.
Can cause personal injury.
• Use eye protection to prevent splashing the
detergent solution in your eyes.
• Wear rubber gloves to avoid prolonged skin
contact with the detergent.
• Keep detergent solution out of the reach of
children.
