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.
Do not install on the floor or directly to the ground.
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.
Two light-emitting diodes LED(s), ON and CHECK, are
included with the F57. The ON LED lights when the
solidstate 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” on page 2.
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.

F57A,B FLUSH-MOUNT COMMERCIAL ELECTRONIC AIR CLEANER
568-0083—07
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.
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 ft2(12m x 14m = 168m2).
2. Assuming ten air changes per hour, with an 1800 ft2
(168m2) area, the graph (Fig. 3) indicates a require-
ment 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 (1m3/min) per person. For 75 people, the rec-
ommended air circulation would be:
75 people x 35 cfm (1m3/min) per person = 2625 cfm
(75m3/min).
2. F57A capacity (HI setting) is 1030 ft3/min
(29m3/min).
Number of F57As required =
2625 ft3/min/1030 ft3/min = 2.5 or 3 units.
or
F57B capacity (HI setting) is 485 cfm (14m3/min).
Number of F57Bs required =
2625 ft3/min/485 ft3/min = 5 units.
EXAMPLE 3:
Sizing by air changes per hour and room volume.
A shop proprietor wants to use electronic air clean-
ing 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) ceil-
ing. 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 ft3
(8m x 12m x 4.5m = 432m3).
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 com-
pletely eliminate, smoke.
15,000 ft3x 10 air changes per hour = 150,000 ft3/hr
(432m3x 10 air changes per hour = 4320m3/hr).
Then determine the volume of air to be circulated
each minute.
150,000 ft3/hr
60 min/hr = 2500 ft3/min
4320 m3/hr
60 min/hr = 72m3/min
3. F57A capacity (HI setting) is 1030 ft3/min
(29m3/min).

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 Home and Building Control
Sales Representative.
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).

Air Vent
The air vent helps to control gaseous contaminants such
as by-products of cigarette smoking by allowing some of
the air circulated through the F57 to be discharged into the
return plenum.
To use the air vent, remove the five inch knockout in the
side of the F57 cabinet. See Fig. 7. When venting into the
false ceiling cavity, leave the vent fully open. When ducting
into the return plenum, install damper and position it to
reduce the opening by 50 percent.

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 con-
taminates 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 150ºF and 190ºF (66ºC and 88ºC). 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 (150ºF to 190ºF
[66ºC to 88ºC]) 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.
aDo not use to clean prefilters.
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 operating, 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 care-
ful 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.
