PLANNING THE INSTALLATION

WARNING

Explosion Hazard. Can cause property damage, severe injury, or death.

1. Do not install or use the F90 where there is any danger of gas, vapor, or dust explosion.

2. Do not install or use the F90 if explosion-proof electrical fixtures are specified.

Application and Operation

The F90 Self-Contained Electronic Air Cleaner is used where

overhead air cleaning is required (restaurants, conference rooms, lounges, and offices).

The F90 provides its own air circulation and is used in any situation that requires the removal of contamination from an enclosed area.

The F90 is not explosion-proof. Do not use the F90 where dangerous levels of potentially explosive gases, vapors, or dusts are present in the cleaning area.

68-0103—4

F90A,B SELF-CONTAINED COMMERCIAL ELECTRONIC AIR CLEANER

The F90 is equipped with two standard light-emitting diodes (LEDs) and one optional LED.

ON LED: Lights when the solid state power supply is

powered and operating normally.

CHECK LED: Lights if the F90 requires service or if the

test button is pressed.

WASH LED (if used): Lights when cell washing is overdue.

To understand the operating sequence of the F90, refer to Fig. 3.

Determine Number of F90 Needed

The sizing procedure determines the number of F90s needed for any application. The correct number required for a particular application depends on: — type of contamination. —number of occupants. —volume of the room. — use of the room. — outdoor air quality.

AIR CLEANER IS POWERED.

FAN DRAWS CONTAMINATED AIR INTO THE BOTTOM OF THE F90.

LARGE PARTICLES ARE CAUGHT IN THE PREFILTER.

SMALL PARTICLES PASS THROUGH THE PREFILTER.

This sizing information in the following Examples 1, 2, and 3 was generated using the ASHRAE Handbook of Fundamentals, 1990 and the ASHRAE Standard 62-1989, Ventilation for Acceptable Indoor Quality. These examples simplify the sizing procedure for most applications. Use this information as a guide; however, keep in mind that the F90 has different capacities for each fan speed (see Specifications section).

The number of air changes per hour determines the number of F90s needed. More air changes per hour than indicated are unnecessary because the ASHRAE data from which these examples were constructed is conservative. Fewer air changes per hour can be compensated for by bringing in more outdoor air to maintain low contaminant levels or tolerating a partially cleaned atmosphere. Either may be acceptable to some users.

Regardless of the method used for calculation, the architectural features, lighting fixtures, sprinkler system, ducts, and grilles in the room to be cleaned may influence the number of F90s required. For ambient air cleaning, establish a uniform airflow pattern throughout the entire space. When there is a lack of mounting space, fewer F90s than indicated may be installed. More F90s may be required for oddlyshaped rooms that do not have even airflow.

If any questions should arise, consult your full-service distributor or local Honeywell Home and Building Control Sales Representative.

To calculate the number of F90s needed using occupant load, refer to Example 2 (page 6).

To calculate the number of F90s needed using air changes per hour and room volume, refer to Example 1 (page 5) or Example 3 (page 6).

SMALL PARTICLES REMAINING IN THE AIR ENTER THE IONIZER SECTION.

IN THE IONIZER SECTION, SMALL PARTICLES RECEIVE AN INTENSE ELECTRICAL CHARGE.

THE SMALL CHARGED PARTICLES ENTER THE COLLECTING SECTION WHERE THEY ADHERE TO THE COLLECTOR PLATES OF OPPOSITE CHARGE.

CARBON FILTERS (IF USED) ABSORB ODORS AND OTHER GASEOUS CONTAMINANTS.

CLEAN AIR PASSES THROUGH THE FAN AND IS DISCHARGED IN FOUR DIRECTIONS INTO THE ROOM, PARALLEL TO THE CEILING TO CREATE A COANDA AIR FLOW PATTERN.

M1527A

Fig. 3. F90 operating sequence.

Choose Location

Mount the F90 on the ceiling near the center of the room. A 45° diagonal mounting prevents stale air build-up in corners and may allow use of F90s at lower speeds. See Fig. 4. In larger rooms, divide the area into sections and mount an F90 in the center of each section. In rooms requiring varying levels of air cleaning, concentrate F90s where air cleaning is required most. See Fig. 4.

NOTE: To assure even air distribution, the F90 draws air into

the bottom of the air cleaner and discharges air in four directions as shown in Fig. 5. This Coanda air flow pattern assures that the clean air is distributed to all parts of the space. Also, if possible, mount the F90 to aid the air circulation already established in the room.

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.

EXAMPLE: An office requires 20 cfm per person because

the standard estimates some smoking, some copy machine operation, etc. The standard assumes outdoor air will be cleaned to less than 75 micrograms per cubic meter prior to introduction into the space. ASHRAE Standard 62-89 states that supplemental air cleaning to control smoke or additional outside air must be provided as required.

Example 1. Sizing by Air Changes per Hour and Room Volume

An office measures 40 x 45 feet (12 x 14 meters) with a 15 foot (4.5 meter) ceiling. How many F90As should be installed?

Solution:

1. Find the room volume: 40 x 45 x 15 feet = 27,000 cubic feet, (12 x 14 x 4.5 meters = 756 cubic meters).

2. Assuming seven air changes per hour, with 27,000 cubic feet (756 cubic meters) volume, the graph below indicates three F90As are required.

3. Clean outdoor air is also required to replenish oxygen and dilute gaseous contaminants. 20 cfm per person is required for offices.

engages the height adjusting nuts. See Fig. 11B.

Mounting the F90 Using the 118636C Wall Mounting Kit (Accessory)

The transition plate (Fig. 10) allows the F90 to be mounted by one person. In the two-step process, the mounting plate is first secured directly to the ceiling joists. See Fig. 11. Then the F90 is mounted to the transition plate.

Eight flanged locknuts (four large, four small) and four 3/8 by 3 in. (10 by 76 mm) lag screws are provided with the transition plate. The four large locknuts adjust the F90 height, level the F90, and provide stops for the F90 top plate (when tightened). The four smaller locknuts secure the F90 to the ceiling joists.

1. Screw a large height-adjusting nut on each stud. Assure

that the large nut is screwed on with its flanged portion down. See Fig. 11A.

2. Position and level the height adjusting nuts so flanges

are flush with the lag screw heads or the protruding threaded steel rods.

3. Screw a small securing nut on each stud, leaving a 1/2

in. (13 mm) space between it and the height adjusting nut. See Fig. 11A.

4. Lift the F90 into position and locate the four studs.

5. Raise the F90 so that the four studs pass through the

keyhole openings.

6. Slide the F90 horizontally so the studs are located at

the slot end of each keyhole opening.

NOTE: As viewed from the F90 or floor side, the slot

portion of each keyhole is above the surface of the top plate. Position the F90 so the studs are located at the slot end of each keyhole. When the securing nuts are tightened, they should nest firmly in the sockets to prevent any lateral movement.

Tw o wall mounting brackets are used to support the F90. See Fig. 12. The two brackets must be mounted on the wall with 16 in. (406 mm) for the F90A or 8 in. (203 mm) for the F90B between centers so that the lag bolts will align with the F90 mounting holes. Fasten the brackets to the wall studs with lag screws. On masonry walls, use appropriate screw anchors.

Wiring

IMPORTANT

All wiring must comply with local codes and ordinances.

Power Cord

IMPORTANT

Power supply cord must not be concealed above the ceiling or behind the walls.

The F90, 120 Vac has a standard 3-prong plug on a 10 foot (3 meter) power cord. There must be a standard grounded outlet within 10 feet (3 meters) of the F90. The F90, 220/240 Vac power cord terminates in stripped leadwires for installation of a locally purchased plug.

• Do not use an extension cord to power the F90.

•Keep the power cord out of the reach of building occupants.

•Keep the power cord away from water.

• Do not route the power cord near sharp objects that can damage the cord insulation.

WEAR GLOVES TO PROTECT HANDS FROM DETERGENT SOLUTION.

Cleaning the F90

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.

Clean cells with an alkaline base detergent solution. Soaking the cells in commercial or home electric dishwasher detergent, powder or liquid, works well. Use the hottest water possible (hotter than 160°F (71°C)). If soaking does not clean the cells, use high velocity detergent spray or steam. Full service distributors provide a regular cleaning service to commercial establishments.

The WASH LED (if used) lights when cell washing is overdue. When the WASH LED lights, wash the cells and wipe the ionizer wires. Frequent cell cleaning keeps WASH LED from lighting.

The F90 needs servicing if it is damaged or if efficiency is substandard, if abnormal voltages are measured, or if the CHECK LED lights.

Cleaning the Cell Using Alkaline Base Detergent

1. Use a container such as a laundry tub or plastic tank

2. Mix the alkaline base detergent with hot water, carefully

Opening the Cover and Removing the Cells and Prefilters

WARNING

Hazardous Chemical. Can cause personal injury.

Wear rubber gloves, eye protection, and a rubber apron for protection from the strong cleaning chemicals. Keep detergent solution out of reach of children.

that is large enough to hold at least one cell.

following the instructions on the detergent package.

• Use commercial or home electric dishwasher detergent (either powder or liquid). Do not use soap or acid base cleaners or solvents.

• Assure the water temperature is between 150°F and 190°F (66°C and 88°C).

• If using cold water detergent, follow the instructions included with the detergent.

NOTE: Cold water detergent cleans less effectively

than hot water detergent.

CAUTION

1. Before servicing the F90, turn off power to the F90.

2. When servicing the F90, stand on a stable work platform or ladder.

1. Open the cover by pulling the two latches located on

the front of the cover and swinging the cover down until it hangs. See Fig. 14.

2. Remove the prefilter and the cell from the channel

guides.

3. Replace the activated carbon filter (if used), if it

needs replacement.

Cleaning the Prefilter

1. Shake out or vacuum the accumulated contaminants

from the prefilter. If necessary, soak the prefilter in alkaline detergent solution. Do not soak the prefilter in an acid detergent solution or use high pressure water, air, or steam to clean the prefilter.

NOTE: Wash the cell before washing the prefilter. If the

prefilter is washed first, lint residue from the prefilter will contaminate the wash water and deposit inside the cell. Dispose of the wash water after each use.

Fig. 16. When cleaning cell, agitate in detergent solution.

3. Carefully wipe off ionizer wires before prerinsing.

4. Prerinse the cell in hot water before submerging

in detergent.

5. Soak the cell in the solution for up to 15 minutes.

Agitate the cell in the solution if necessary. See Fig. 16.

6. Remove the cell from the detergent solution.

7. Place the cell in another container of clear hot water

(150°F to 190°F (66°C to 88°C)) for final rinsing. Rinse the cells for five to ten minutes.

8. Remove the cell from the rinse water. Allow the cell to

drain and dry before energizing. Stand cell on one corner for optimum water drainage.

68-0103—4

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. To prevent damage to prefilter, do not use these methods to clean the prefilter. See Fig. 17.

Water method—Be careful to avoid damage to the cell. If

detergent is required, use an alkaline base detergent. Do not use an acid detergent. Aim water straight on or at a very slight angle when rinsing collector plate side of cell. This will minimize uneven spacing of collector plates caused by water pressure.

Steam method—Be extremely careful when steam

cleaning to avoid warping or bending the collector plates of the cell. Remember that the cell will be hot after steam cleaning, and be extremely careful to avoid burns. Use only low pressure or wet steam.

NOTE: Assure the steam pressure is less than 5 psi (35 kPa)

and steam temperature is less than 250°F (121°C).

Discolored Aluminum

After cleaning, the cell and prefilter occasionally look stained. If the stain is black or very dark, it is probably dirt residue. This can lower the F90 efficiency. Clean and rinse the cell and prefilter again.

If the stain is white, it is detergent residue. This lowers the F90 efficiency and can corrode the aluminum. Rinse the cell and prefilter again.

If the stain is tan, yellow, or a thin film, it is probably tobacco smoke or other airborne dirt. Moderate discoloration does not affect the F90 efficiency. Recleaning is not necessary.

Removing Specific Contaminants from the Cell

The following list gives the appropriate cleaning procedure for types of contamination often found on cells and prefilters. Cleaning procedures are listed in order of preference. Be careful not to bend cell blades.

Reinstalling the Cell, Prefilter, and Activated Carbon Filter if Used

1. Wipe off surface dirt inside and outside of the grille and

cover.

2. Replace the activated carbon filters with new filters if

needs replacement. See Fig. 18.

3. Inspect the cells for broken ionizer wires and bent

collector plates. Bend moderately bent or warped collector plates back into shape. Replace broken ionizer wires replaced for top efficiency as instructed on page 15.

Replacing Ionizer Wires

Broken or bent ionizer wires can cause an electrical short to ground, often resulting in visible arcing or sparking. Do not use cells until broken wires are removed. Cells can be used temporarily with one wire missing, but replace the wire as soon as possible. Replacement wires are supplied cut to length with eyelets on both sides for easy installation. Order part no. 136434AA. To install:

1. Hook the eyelet on one end of the wire over the spring

connector on one end of the cell. See Fig. 19. Be careful to avoid damaging the spring connector or other parts of the cell.

2. Hold the opposite eyelet with a needlenose pliers and

stretch the wire the length of the cell. Depress the opposite spring connector and hook the eyelet over it.

3. Check the cell for short circuits using an ohmmeter. See

Fig. 20. Check the resistance between the frame of the cell and both the ionizer and the collector contacts. In each case, the resistance should be infinite.

Modifying to Reduce Ozone Odor

In normal operation, the F90 generates a trace amount of ozone that is considerably under the limit prescribed by the U.S. Food and Drug Administration (FDA). During the first week or two of operation, the amount may be higher because of sharp edges on some of the new high voltage metal parts. Normal use dulls these edges in a short time.

Fig. 19. Installing new ionizer wire.

A person with an average sense of smell can detect the odor of ozone indoors in concentrations as low as 0.003 part per million (ppm). OSHA workplace regulations permit up to

0.100 ppm ozone concentration. The F90 contributes 0.005 to

0.010 ppm of ozone to the indoor air. The U.S. FDA and Health and Welfare Canada recommend that indoor ozone concentration should not exceed 0.050 ppm. As a comparison, the outdoor ozone level in major cities is sometimes higher than 0.100 ppm.

68-0103—4

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.

NOTE: The performance switch must be set solidly in either

HI or LO position and not between, or the F90 may not function properly. See Fig. 21.
