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).
