Honeywell F111 Series 1 - Manual (Page 8)

F111 (SERIES 1,2,3) IN CEILING MEDIA AIR CLEANER
68-0198-2 Revised 5-09 8
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
1,2,3) 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 1,2,3) 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 prevent
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:
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
metal screen mesh so it 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. For Series 1 and 2 only. Fasten the filter tabs. Be sure
there is a snapping sound when they are fastened. The
tabs are commercial Velcro and require more force to
fasten.
7. For Series 3 only. Lock and secure the particle filter
into place by closing both latches
IMPORTANT
Do not touch the pleated filter media. Handle only the
filter frame to prevent damage to the filter media.
8. 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. For Series 1 only. Support the adsorbent module with
one hand and release the fastener.
3. For Series 2 and 3. Support the adsorbent module with
one hand and turn open the catches.
4. 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.
5. Place the spent module in a plastic trash bag and
dispose of properly.
6. Remove CPZ™ sorbent modules from their packaging
and install.
7. For Series 1 only. Be sure the fastener tabs are facing
downward and fasten them.
8. For Series 2 and 3 only. Be sure both catches are
turned down and filter rests firmly on catches.
9. Install 1 startup-filter in each end of grill.
10. Close and latch the lid.
On initial startup, a small amount of dust can blow from the air
cleaner. This is normal and stops a few minutes after startup.
The startup-filters will catch all the dust. The startup-filters are
placed in the two exit outlets on the grill. After running the unit
for 5 minutes, turn off the unit. Remove and discard the two
start-up filters.
