F111 (SERIES 3) IN CEILING MEDIA AIR CLEANER
The CPZ™ sorbent module has the ability to collect and
hold gas-phase compounds and vapors typically found in
commercial and light industrial facilities. These gases and
vapors frequently appear as odors that, at times, can be
annoying and irritating. The modules become saturated
after collecting 25% to 50% of their weight in gaseous
odors. The quantity of CPZ™ material provides adequate
dwell time to ensure up to 95% collection efficiency in the
first pass. This also provides a long maintenance-free
service life.
The minimum recommended air exchange rate is 2.5 times
per hour. In a heavily contaminated area, up to 15 air
exchanges per hour can be necessary. The factors that
determine what the rate of air exchange should be are:
• Generation rates of the various pollutants;
• Concentration level of the pollutants;
• Desired contamination reduction level.
Airborne contaminants will always be present in the air
where contaminant generations take place. Air cleaning
systems and ventilators do not eliminate airborne
contaminants, they reduce the excessive accumulation of
the contaminants. To eliminate the contamination, the
source of contamination must be removed.
Local, Federal and professional ventilation engineering
standards and codes prescribe minimum ventilation rates
to dilute air contamination in specific applications. The
ventilation rates usually assume the injection of outdoor
air measured as air exchange rate. The use of the F111
(Series 3) air cleaner to comply with ventilation
requirements is an acceptable alternative to ventilation
with outdoor air. However, at least 20% of a specified
ventilation rate or code must be derived from outdoor air.
The F111 (Series 3) air cleaner filtered and recirculated air
can be the remaining 80%.
SERVICE
CAUTION
Electrical Hazard.
Can cause personal injury or equipment damage.
Turn off power before installing or servicing the air
cleaner.
IMPORTANT
Be sure to change filters as recommended to pre-
vent reduced airflow in the air cleaner.Stand on a
stable platform when working with the air cleaner.
The useful life of the CPZ™ sorbent modules may vary from
4 to 24 months, depending on the application. In most
applications, the sorbent media life ranges from 12 to 18
months. The particle filter life ranges from 6 to 24 months
with 12 to 24 months as an average. The modules and
filters need to be changed more frequently in facilities that
operate 24 hours a day.
Prefilter
The disposable prefilter collects large dust particulates
and lint- type airborne fibers. Check the filter every two
weeks to determine the replacement frequency:
68-0198—05
1. Slowly open the lid, supporting the lid so the filters do
not fall out.
2. Remove the dirty prefilter.
3. Install the new prefilter in the air cleaner lid. Position
the prefilter so that the Air Flow Direction Arrow is
facing upward when the lid is closed.
4. Close and latch the lid.
Particle Filter
The particle filter collects particulates that pass through
the prefilter. The filter life is typically from 1 to 2 years.
There is decreased air quality and a pulsing sound when
the filter is filled with contaminants. The filter must be
replaced when the pulsing sound is noticed.
NOTE: The filter must be replaced. Washing, vacuuming
or reverse air blasting does not clean it.
1. Slowly open lid, supporting it so the filters do not fall
out.
2. Open the securing strips and with both hands. Slide
the filter toward you.
3. Place spent filter in a plastic trash bag and dispose of
properly.
4. Inspect the motor brackets for loose fasteners and
tighten as necessary.
5. Install the new filter noting the direction of airflow
arrow.
6. Lock and secure the particle filter into place by clos-
ing both latches.
IMPORTANT
Do not touch the pleated filter media. Handle only
the filter frame to prevent damage to the filter
media.
7. Close and latch the lid.
CPZ™ Adsorbent Module
The CPZ™ adsorbent module is used to collect gases,
vapors, odors and volatile organic compounds (V.O.C.) from
the air that passes through the air cleaner. Adsorbents
collect and hold 25% to 50% of their weight in odorous
gases and vapors. The impurities are collected until the
adsorbents reach saturation. At saturation, the adsorbents
emit a continuous strong pungent odor. If the air cleaner is
turned off for 8 to 10 hours, there will a temporary odor
when it is turned back on. If the odor persists for 30
minutes, it is time to replace the filters.
NOTE: When tobacco smoke is a contaminant, both the
particle filter and the adsorbent filter will need to
be serviced at the same time.
1. Slowly open the lid, supporting the lid so the filters do
not fall out.
2. Support the adsorbent module with one hand and
turn open the catches.
3. Use two hands and slide the filter from the housing.
IMPORTANT
The module weighs about 26 lb (12 kg) and can be
hard to handle.
4. Place the spent module in a plastic trash bag and
dispose of properly.
5. Remove CPZ™ sorbent modules from their packaging
and install.
