The F90A,B Self-Contained Commercial Electronic Air

Cleaners are ceiling-mounted and remove airborne

contaminants such as tobacco and cooking smoke, dust,

pollen, bacteria, and larger viruses from the air circulated

through the unit.

FEATURES

• Removes up to 95 percent of the staining dirt from the air,

as measured by the Initial Dust Spot Method using

atmospheric dust; refer to the American Society of

Heating, Refrigerating, and Air Conditioning Engineers

(ASHRAE) Standard 52-76.

• Provides Coanda air distribution by drawing in dirty air

from below, cleaning it electronically, and discharging the

clean air in four directions parallel with the ceiling.

• Three-speed fan circulates up to 1250 cfm (35 m3/min) for

F90A and 550 cfm (15.5 m3/min) for F90B.

• Solid state power supply is self-regulating, maintains peak

efficiency over a wide range of cell dirt loading conditions,

and provides nonlethal current levels.

• Interlock switch prevents operation when the cover is

open or the grille is not in place.

• Heavy duty commercial cells, prefilter, and grille are

removable for cleaning.

• Three-position adjustable discharge louvers control the

direction of discharged air.

• Light emitting diodes (LEDs) indicate ON and CHECK;

WASH LED optional.

• Test button shows presence of high voltage.

• Available with gray finish or woodgrain with black trim.

F90 Outdoor Air ASHRAE Standard 62-89 specifies that every commercial space be provided with fifteen cfm per occupant of outdoor air to replenish oxygen and dilute CO2. If other internal sources of gaseous contamination are present, additional outside air is needed to dilute the contamination. DANCE FLOOR STAGE F90 F90 F90 LOW SMOKING LEVEL AT STAGE AND DANCE FLOOR.

F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER Example 2. Sizing by Occupant Load A cocktail lounge averages 85 occupants. How many F90As should be installed? Solution: F90As Required = ASHRAE Recommended Air Circulation/Minute F90A Capacity 1. ASHRAE recommended minimum air circulation is 30 cubic feet per minute (cfm) (0.85 m3/minute) per person. For 85 people, the recommended air circulation would be: 85 people x 30 cfm (0.85 m3/minute) per person = 2550 cfm (72 m3 minute). 2.

F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER CAUTION IMPORTANT 1. When mounting near walls, allow at least 16 in. (406 mm) for cell installation and removal and 15 in. (381 mm) for cover installation and removal. See Fig. 7. 2. Select a structurally strong part of the ceiling or wall for mounting. Do not mount the F90 to a suspended ceiling, to plaster, or to wallboard. If necessary, construct strong framing to support the weight of the F90.

F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER Installing Cover Check F90 Operation 1. Before installing, study the inside of the F90 cover. One end has two latches and the other has two hinge pins. To properly install the cover, connect the hinge pins to the hinges. 2. Attach the hinge pins by lifting the cover above the hinge and lowering the pins into the hinges. If the cover is properly attached, it can hang below the F90. 3.

F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER Cleaning the F90 Cleaning the Cell Using Alkaline Base Detergent The F90 removes a variety of contaminants from the air. As it cleans the air, the F90 cells and prefilters become dirty, lowering the cleaning efficiency. To maintain the F90 reliability and efficiency, regularly clean, inspect, and service the F90 cells and prefilters. WARNING Hazardous Chemical. Can cause personal injury.

F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER 9. Carefully wipe ionizer wires to remove any remaining residue. 10. Check the collection plates of the cell for any detergent residue. If any residue is remaining, repeat the rinse and detergent soaking process until collector plates are clean. Buildup can reduce the F90 efficiency. Cleaning the Cell Using High Velocity Water Pressure or Low Pressure Steam Alternate methods can be used to clean some contaminants from the F90 cell.

Using high velocity water or steam to clean cells. 6. Slide the cells into the channel guides until they touch the backstop of the F90. Assure the cell airflow arrow is pointing toward the fan. In this position, the ionizer wires are facing downward (away from the fan). 7.

F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER If desired, the ozone generated by the F90 can be reduced in one of two ways: • Install the optional activated carbon filters. • Open the cover and move the F90 performance switch to the LO setting. Close the cover. With the switch in LO, the cleaning efficiency is reduced 5 to 15 percent, depending on airflow. Tools And Equipment Troubleshooting the F90 requires: • Needlenose pliers for stringing ionizer wires and inserting edge connectors.
