PLANNING THE INSTALLATION
WARNING
Explosion Hazard Possible
Can cause personal injury or equipment damage.
Do not install or use the F57 where there is any
danger of gas, vapor, or dust explosion.
Do not install when explosion-proof electrical fixtures
are specified.
Application and Operation
The F57 Flush-Mount Electronic Air Cleaner is designed for
use in restaurants, conference rooms, lounges, and offices
where overhead air cleaning is required.
Because the F57 provides its own air circulation, it can be
used in any situation that requires the removal of
contamination from an enclosed area.
Because it is not explosion-proof, the F57 must not be used if
there are dangerous levels of potentially explosive vapors,
gases, or dusts present in the cleaning area.
When the electronic air cleaner is powered, the fan draws the
contaminated air into the electronic air cleaner. Particles that
are too small to be caught in the prefilter are given an intense
electrical charge in the ionizer section of the electronic cell.
As the air passes through the collecting section of the cell,
the charged particles adhere to the collector plates, which
have a strong opposite charge. The cleaned air passes
through the fan component and re-enters the building
space.
Fig. 3. F57 sizing by air changes per hour and room area. In most cases, one F57B is equivalent to half an F57A because the
F57B airflow, although less than 50 percent of F57A airflow, is more effectively applied via several locations.
Two light-emitting diodes LED(s), ON and CHECK, are
included with the F57. The ON LED lights when the solid-
state power supply is powered and operating normally. The
CHECK LED lights if the F57 requires service attention or if
the test button is pressed. A WASH LED is also supplied
with the F57 but it is not factory installed. It can be field
installed using 4074 EMH Bag Assembly which is supplied
with the F57. See Fig. 4. The WASH LED lights to indicate
cell washing is overdue.
Determine Number of F57s Needed
The sizing procedure determines the number of F57As or Bs
needed. The correct number required for a particular
application depends on:
— type of contamination,
— number of occupants,
— volume of the room,
— use of the room,
— outdoor air quality.
This sizing information (Fig. 3) was generated using the
ASHRAE Handbook of Fundamentals, 1985; the ASHRAE
Standard 62-1989, Ventilation for Acceptable Indoor Air
Quality. It simplifies the sizing procedure for most
applications. Use this information as a guide; however,
remember that the F57 has different capacities for each fan
speed; see Specifications section.
The number of air changes per hour determines the amount of
air cleaning obtained. More air changes per hour than
recommended in the graph above are unnecessary because
the ASHRAE data used in the calculation is conservative.
Fewer air changes per hour than recommended in the graph
can be compensated for by bringing in more outdoor air to
maintain low contaminant levels, or tolerating a partially
cleaned atmosphere, which may be acceptable to some
users.

Regardless of the method used for calculation, the physical
limitations of the space to be cleaned can influence the
number of electronic air cleaners required. For ambient air
cleaning, it is essential to establish a uniform airflow pattern
throughout the entire space. Fewer electronic air cleaners can
be installed because of a lack of mounting space. More units
may be required due to an oddly-shaped room that does not
lend itself to an even airflow.
If any questions should arise concerning size, consult your
distributor or local Honeywell Commercial Air Cleaner
Distributor.
Choose Location
The F57 is mounted horizontally, and can be used in almost
any air cleaning application that has a suspended ceiling. For
the most efficient operation, place the F57 as close as
possible to the contaminant source.
When placing the F57, be sure that the clean air discharge
enhances the airflow patterns of the area to be cleaned. For
example, do not place the air cleaner so its discharge disrupts
the flow from the central air handling system supply registers.
The shape of the room, location of central air conditioning
diffusers and returns, architectural features, and ceiling
obstruction will affect optimum F57 location in the ceiling.
For partial dilution of odor and gaseous contaminant, some
F57 discharge air can be bled off into the area above the
suspended ceiling, or a run of 12 ft (3.7m) or less of 5 in.
(127 mm) round duct can be vented outdoors or to an exhaust
duct that is always at negative pressure.
Determine if the air vent of the unit must be ducted to the
return air plenum (as some local building codes require).
For duct connection, make sure the access panel to the vent
is removed so a 5 in. (127 mm) diameter duct can be
connected to the collar (collar is field supplied).
EXAMPLE 1: Sizing by air changes per hour and room area
(using the graph in Fig. 3).
An office measures 40 x 45 ft (12 x 14m). How
many F57 air cleaners should be installed?
SOLUTION:
1. Find the floor area.
40 ft x 45 ft = 1800 ft
2
(12m x 14m = 168m
2
).
2. Assuming ten air changes per hour, with an 1800
ft
2
(168m
2
) area, the graph (Fig. 3) indicates a
requirement for two F57A units, or four F57B units.
EXAMPLE 2: Sizing by occupant load.
A cocktail lounge averages 75 occupants. How
many F57 air cleaners should be installed?
SOLUTION: Number of F57s required =
ASHRAE Recommended Air Circulation/Min
F57 Capacity
1. ASHRAE recommended minimum air circulation
is 35 cfm (1m
3
/min) per person. For 75 people,
the recommended air circulation would be: 75
people x 35 cfm (1m
3
/min) per person = 2625 cfm
(75m
3
/min).
2. F57A capacity (HI setting) is 1030 ft

(29m
3
/min).
Number of F57As required = 2625 ft
3
/min/1030

/min = 2.5 or 3 units.
or
F57B capacity (HI setting) is 485 cfm (14m

Number of F57Bs required = 2625 ft
3
/min/485 ft
3
/

EXAMPLE 3: Sizing by air changes per hour and room
volume.
A shop proprietor wants to use electronic air
cleaning to remove high levels of smoke from
the air. The shop is 25 x 40 ft (8 x 12m) with a
15 ft (4.5m) ceiling. How many F57 air
cleaners will be required?
GUIDELINE: In the absence of other information, select
the correct number of F57 units to provide
between 10 or 20 air changes per hour,
depending on contaminant level. The air
cleaner should be located directly above or
as close as possible to the source of
contamination.
SOLUTION: Number of F57s required =
Desired Air Circulation/Min
F57 Capacity
1. Calculate the volume of the room.
25 ft x 40 ft x 15 ft = 15,000 ft
3
(8m x 12m x 4.5m = 432m
3
).
2. Determine the volume of air to be circulated each
hour. Ten air changes per hour are used here on
the assumption that the intent is to reduce, but
not completely eliminate, smoke.

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.

• Provide a large enough container, such as a laundry tub
or plastic tank, to hold at least one cell.
• Mix alkaline base detergent, such as commercial or home
electric dishwashing detergent (either liquid or powder)
with hot water. Follow the instructions on the detergent
package. The water temperature should be between
150°F and 190°F (66°C and 88°C). When using a cold
water detergent, follow instructions included with the
detergent.
NOTE: Be sure to avoid prolonged skin contact with the
solution. Do not splash solution in eyes.
• Soak the cells in the solution for up to 15 minutes; agitate
the cells up and down. See Fig. 12.
Fig. 12. Agitate the cells in the water.
• Remove the cells from the detergent solution; spray with
hot water as a prerinse, if desired and place cells in
another container of clear hot water (150°F to 190°F
[66°C to 88°C]) for final rinsing. Rinse the cells for five to
ten minutes.
• Remove the cells from the rinse water. Allow the cells to
drain and dry before energizing them. For optimum water
drainage from tubes, stand the cell on one of its corners.
• Wipe ionizer wires to remove any deposits remaining on
the wires.
• Check the collection plates of the cells for any detergent
residue. Repeat the rinse process if there is any residue
remaining. Buildup can reduce the F57 efficiency.
About Discolored Aluminum
Occasionally, the cell or prefilter can seem stained after the
soaking process. When the stain is black or very dark, it is
probably dirt residue and the cell should be rewashed. White
detergent residue can also affect the F57 efficiency and
should be rinsed off. When yellowing appears, it is probably
staining from tobacco smoke or other airborne dirt.
Moderate discoloration does not affect the F57 efficiency.
Cleaning the Cells Using Air
Pressure, Water Pressure or Low
Pressure Steam
The following alternative methods can be used to clean some
contaminants from the F57 cells. See Fig. 13. To prevent
damage to the prefilter, do not use pressure or steam
methods on the prefilter.
• High Pressure Air or Water. Care should be taken to avoid
damage to the cells. If detergent is required with the high
pressure water, use an alkaline base detergent. Do not
use an acid detergent.
• Steam. Extreme care must be taken when steam cleaning
to avoid warping or bending the collector plates of the
cells. Remember that the cells are hot after steam
cleaning and care must be taken to avoid burns. Use only
low pressure or wet steam.
NOTE: Do not use steam at pressure greater than 5 psi
(35 kPa) or temperature hotter than 250°F (121°C).
Fig. 13. It can be necessary to steam or use high pressure
to remove collected cells contamination.

Removing Specific Contaminants
from Cells
The following list gives the appropriate cleaning procedure
for types of contamination often found on cells and prefilters.
Cleaning procedures are listed in order of preference. Be
careful to avoid bending the cell collector plates.
Reinstalling the Cells, Prefilter and
Activated Carbon Filters, If Used
• Inspect the cells for broken ionizer wires and bent collector
plates. Bend warped or bent collector plates back into
shape. For maximum efficiency, replace broken ionizer
wires as instructed in Replacing Ionizer Wires section.
• Wipe ionizer wires.
• Check that cells are completely dry before reinstalling in the
air cleaner. If cells are placed into the air cleaner while still
wet, the electronic cells can short out and arc frequently
when almost dry. Although the system appears to be oper-
ating, the cells may not be cleaning during the drying period.
• Be sure the contact board of the cell is facing the latch side
of the frame.
• Check that the airflow arrow is pointing toward the fan. In
this position, the ionizer wire side of the cell is the farthest
from the fan.
• Ease the edge of the cell into the cell hooks.
• Using both hands, pivot the cell until the contact board
mates with the frame.
• With one hand supporting the cell near the latch, rotate the
latch to a closed position. See Fig. 14.
• Wipe surface dirt from the inside and the outside
of the grille.
• Replace the prefilter in the grille. Be sure that the airflow
arrow is pointing toward the cells.
• Replace activated carbon filters, if used. The F57A carbon
filters fit inside the grille, one on each side of the prefilter.
The F57B carbon filter fits inside the grille on the left side of
the prefilter.
• Close and carefully latch the grille.
Fig. 14. Reinstalling the cell.
Replacing Ionizer Wires
Broken or bent ionizer wires can cause an electrical short to
ground, often resulting in visible arcing or sparking. Remove
broken wires. Cells can be used temporarily with one wire
missing, but replace the wire as soon as possible.
Replacement wires, part no. 136434AA, are cut to length with
eyelets on both sides for easy installation. To install:
1. Hook the eyelet on one end of the wire over the spring
connector on one end of the cell. See Fig. 15. Be careful
to avoid damaging the spring connector or other parts
of the cell.
2. Hold the opposite eyelet with a needlenose pliers and
stretch the wire the length of the cell. Depress the
opposite spring connector and hook the eyelet over it.

Modification to Reduce Ozone
Odor
The electronic air cleaner generates a trace amount of
ozone in normal operation. During the first week or two of
operation, the amount may be higher because of sharp
edges on some of the new high voltage metal parts.
However, normal use and the first wash quickly dull the
edges.
The average person can detect the odor of ozone indoors in
concentrations as low as 0.003 to 0.010 parts per million
(ppm). The electronic air cleaner contributes 0.005 to 0.010
ppm of ozone to the indoor air. The U.S. Food and Drug
Administration and Health and Welfare Canada recommend
that indoor ozone concentration should not exceed 0.050
ppm. As a comparison, the outdoor ozone level in major
cities ranges from 0.020 ppm to 0.040 ppm and even higher.
However, if desired, the ozone generated by the air cleaner
can be reduced in one of two ways:
1. Install the optional activated carbon filter.
2. Open the grille and move the electronic air cleaner
performance switch to the low setting. Close and
relatch the grille. The cleaning efficiency is now
reduced 5 to 15 percent, depending on airflow.
NOTE: Be sure the switch is set to either high or low
position, not between or the unit may not run.
Be careful not to reset the switch when closing
the cover.
