Maintenance
At the time of filter replacement, if a powdery residue is noticed on the tips of the points
in the ionization array of the Enhancement module, proceed to clean them by complet-
ing the following steps:
1. Turn heating and cooling system power off.
WARNING: Electrocution Hazard.
Failure to follow this warning could result in personal injury or death.
Before installing or servicing system, always turn off main power to system. There may be more than one
disconnect switch.
2. Turn the Honeywell Enhanced Air Cleaner switch to the off position.
3. Remove the Honeywell Enhanced Air Cleaner door.
4. Models FH8000A: Unplug the power cord and flow sensor cable (if connected) from the enhancement
module (see Fig. 11 on page 15).
Models FH8000F: Unplug the power cord from the enhancement module (see Fig. 15 on page 17).
5. Slide out the enhancement module assembly and safety screen.
CAUTION: Personal Injury Hazard.
Failure to follow this caution may result in personal injury.
Ionizer points are SHARP and may cause injury. Use caution and wear appropriate protective clothing and
gloves when handling parts or performing maintenance.
6. Slide out the Safety Screen and set aside.
NOTE: Best cleaning tools: 2 in. (51 mm) wide (or greater) synthetic or natural bristle brush with a
5 in. (157 mm) handle (see Fig. 18) or vacuum cleaner with brush attachment.
7. Gently stroke the ionization points on the top plane of each bar with enough brush depth to hit front and
back tips of the points in the ionization array. Use a gentle back and forth brushing motion to clean any small
accumulations from the tips of the points. If desired, use vacuum cleaner with brush attachment to gently
vacuum the frame and components of enhancement module. (See Fig. 19 on next page.)
