Service - Honeywell F111U Product Data

F111U IN-CEILING MEDIA AIR CLEANER WITH ULTRAVIOLET AIR TREATMENT SYSTEM
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 or
conditioned air (HVAC) measured as air exchange rate. The
use of the F111U 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 or conditioned
air. The F111U air cleaner filtered and recirculated air can be
the remaining 80%.
Verify F111U Operation
1. Turn on power to the Air Cleaner and check for proper
operation for 2 to 3 minutes.
2. Listen for a smooth, powerful blower sound and air
discharging from both ends of the air cleaner.
3. The installer should verify that the ultraviolet lamps are
operating by viewing the lamp indicator on the lamp
knob.
IMPORTANT
Do not attempt to look directly into the unit to see the
illuminated ultraviolet lamps.

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.
CAUTION
All Filters must be provided from Air-Pure
Systems to maintain U.L. Certification and
Warranty.
The high-efficiency particle filter life ranges from 6 to 24
months with 12 to 24 months as an average. More frequent
replacement may be neccessary in some applications
depending on the load of the filter.
Prefilter
The disposable prefilter collects large dust particulates and
lint- type airborne fibers. Check the filter every two weeks to
determine the replacement frequency. The filters need
replacement when a pulsing sound occurs, .

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 noting direc-
tion of airflow arrow.
4. Close and latch the lid.
High Efficiency Particle Filter
The high efficiency 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 both filter securing latches 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.
IMPORTANT
Do not touch the pleated filter media. Handle only the
filter frame to prevent damage to the filter media.
6. Lock and secure the high efficiency particle filter into
place by closing both latches.
7. Close and latch the lid.
Servicing UV Lamps
CAUTION
Breakable Glass Hazard.
Can cause personal injury.
Be careful when inserting lamps(s) into lamp base.
Wear protective gloves when handling lamp(s).
MERCURY NOTICE
This device contains mercury in the sealed ultraviolet
lamps(s). Do not place your used lamp(s) in the trash.
Dispose of properly.
Broken Lamp Cleanup.
Do not use a household vacuum.
Sweep debris into plastic bag and dispose of properly.
Contact your local waste management authority for
instructions regarding recycling and the proper
disposal of old lamp(s).
CAUTION
UV Lamp Burn Hazard.
Harmful to bare skin.
Can cause severe burns.
Allow lamps to cool 15 minutes before servicing.
