PLANNING THE INSTALLATION

WARNING

Explosion Hazard Possible

Can cause personal injury or equipment damage.

Do not install or use the F57 where there is any danger of gas, vapor, or dust explosion.

Do not install when explosion-proof electrical fixtures are specified.

Application and Operation

The F57 Flush-Mount Electronic Air Cleaner is designed for use in restaurants, conference rooms, lounges, and offices where overhead air cleaning is required.

Because the F57 provides its own air circulation, it can be used in any situation that requires the removal of contamination from an enclosed area.

Because it is not explosion-proof, the F57 must not be used if there are dangerous levels of potentially explosive vapors, gases, or dusts present in the cleaning area.

When the electronic air cleaner is powered, the fan draws the contaminated air into the electronic air cleaner. Particles that are too small to be caught in the prefilter are given an intense electrical charge in the ionizer section of the electronic cell. As the air passes through the collecting section of the cell, the charged particles adhere to the collector plates, which have a strong opposite charge. The cleaned air passes through the fan component and re-enters the building space.

Two light-emitting diodes LED(s), ON and CHECK, are included with the F57. The ON LED lights when the solid-state power supply is powered and operating normally. The CHECK LED lights if the F57 requires service attention or if the test button is pressed. A WASH LED is also supplied with the F57 but it is not factory installed. It can be field installed using 4074 EMH Bag Assembly which is supplied with the F57. See Fig. 4. The WASH LED lights to indicate cell washing is overdue.

Determine Number of F57s Needed

The sizing procedure determines the number of F57As or Bs needed. 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.

This sizing information (Fig. 3) was generated using the ASHRAE Handbook of Fundamentals, 1985; the ASHRAE Standard 62-1989, Ventilation for Acceptable Indoor Air Quality. It simplifies the sizing procedure for most applications. Use this information as a guide; however, remember that the F57 has different capacities for each fan speed; see Specifications section.

The number of air changes per hour determines the amount of air cleaning obtained. More air changes per hour than recommended in the graph above are unnecessary because the ASHRAE data used in the calculation is conservative. Fewer air changes per hour than recommended in the graph can be compensated for by bringing in more outdoor air to maintain low contaminant levels, or tolerating a partially cleaned atmosphere, which may be acceptable to some users.

Fig. 3. F57 sizing by air changes per hour and room area. In most cases, one F57B is equivalent to half an F57A because the F57B airflow, although less than 50 percent of F57A airflow, is more effectively applied via several locations.

EXAMPLE1: Sizing by air changes per hour and room area (using the graph in Fig. 3). An office measures 40 x 45 ft (12 x 14m). How many F57 air cleaners should be installed?

SOLUTION:

1. Find the floor area. 40 ft x 45 ft = 1800 ft ^2 (12m x 14m = 168m ^2 ).

2. Assuming ten air changes per hour, with an 1800 ft ^2 (168m ^2 ) area, the graph (Fig. 3) indicates a requirement for two F57A units, or four F57B units.

EXAMPLE 2: Sizing by occupant load. A cocktail lounge averages 75 occupants. How many F57 air cleaners should be installed?

SOLUTION: Number of F57s required =

ASHRAE Recommended Air Circulation/Min F57 Capacity

1. ASHRAE recommended minimum air circulation is 35 cfm (1m ^3 /min) per person. For 75 people, the recommended air circulation would be: 75 people x 35 cfm (1m ^3 /min) per person = 2625 cfm (75m ^3 /min).
2. F57A capacity (HI setting) is 1030 ft ^3 /min (29m ^3 /min). Number of F57As required = 2625 ft ^3 /min/1030 ft ^3 /min = 2.5 or 3 units. or F57B capacity (HI setting) is 485 cfm (14m ^3 /min). Number of F57Bs required = 2625 ft ^3 /min/485 ft ^3 /min = 5 units.

EXAMPLE 3: Sizing by air changes per hour and room volume. A shop proprietor wants to use electronic air cleaning to remove high levels of smoke from the air. The shop is 25 x 40 ft (8 x 12m) with a 15 ft (4.5m) ceiling. How many F57 air cleaners will be required?

GUIDELINE: In the absence of other information, select the correct number of F57 units to provide between 10 or 20 air changes per hour, depending on contaminant level. The air cleaner should be located directly above or as close as possible to the source of contamination.

SOLUTION: Number of F57s required =

Desired Air Circulation/Min F57 Capacity

1. Calculate the volume of the room.
   25 ft x 40 ft x 15 ft = 15,000 ft ^3
   (8m x 12m x 4.5m = 432m ^3 ).

2. Determine the volume of air to be circulated each hour. Ten air changes per hour are used here on the assumption that the intent is to reduce, but not completely eliminate, smoke.

15,000 ft ^3 x 10 air changes per hour = 150,000 ft ^3 /hr (432m ^3 x 10 air changes per hour = 4320m ^3 /hr).

Then determine the volume of air to be circulated each minute.

150,000 ft ^3 /hr 60 min/hr = 2500 ft ^3 /min

4320m^3/hr 60min/hr = 72m ^3/min

1. F57A capacity (HI setting) is 1030 ft ^3 /min (29m ^3 /min).

Number of F57As required = 2500 ft ^3 /min 72m ^3 /min

1030 ft ^3 /min 29m ^3 /min = 2.4 or 3 units.

or

F57B capacity (HI setting) is 485 cfm (14m ^3 /min).

Number of F57Bs required = 2500 ft ^3 /min 72m ^3 /min

485 ft ^3 /min 14m ^3 /min = 5 units.

Regardless of the method used for calculation, the physical limitations of the space to be cleaned can influence the number of electronic air cleaners required. For ambient air cleaning, it is essential to establish a uniform airflow pattern throughout the entire space. Fewer electronic air cleaners can be installed because of a lack of mounting space. More units may be required due to an oddly-shaped room that does not lend itself to an even airflow.

If any questions should arise concerning size, consult your distributor or local Honeywell Commercial Air Cleaner Distributor.

Choose Location

The F57 is mounted horizontally, and can be used in almost any air cleaning application that has a suspended ceiling. For the most efficient operation, place the F57 as close as possible to the contaminant source.

When placing the F57, be sure that the clean air discharge enhances the airflow patterns of the area to be cleaned. For example, do not place the air cleaner so its discharge disrupts the flow from the central air handling system supply registers.

The shape of the room, location of central air conditioning diffusers and returns, architectural features, and ceiling obstruction will affect optimum F57 location in the ceiling.

For partial dilution of odor and gaseous contaminant, some F57 discharge air can be bled off into the area above the suspended ceiling, or a run of 12 ft (3.7m) or less of 5 in. (127 mm) round duct can be vented outdoors or to an exhaust duct that is always at negative pressure.

Determine if the air vent of the unit must be ducted to the return air plenum (as some local building codes require). For duct connection, make sure the access panel to the vent is removed so a 5 in. (127 mm) diameter duct can be connected to the collar (collar is field supplied).

Cleaning the Commercial Electronic Air Cleaner

The F57 removes a variety of particulate contaminants from the air. In the process of cleaning the air, the air cleaner cells and prefilter become dirty, and the cleaning efficiency is lowered.

To maintain a high standard of reliability and efficiency, it is necessary to periodically maintain the F57. Maintenance includes cleaning the cells and prefilter and inspecting the F57. Service is required if the F57 is damaged, performs at substandard efficiency, measures abnormal voltages, or when the CHECK LED lights.

Regular cleaning with an alkaline-based detergent solution is recommended. Use a commercial or home electric dishwasher detergent, either liquid or powder. The wash frequency is determined by the dirt level in the air. Actual experience or optional WASH LED dictates the period between cleanings.

If the optional WASH LED is connected and the WASH LED comes on, a cell washing is overdue. Frequently wash the cells and wipe any material buildup off the ionizer wires. This prevents the wash led from coming on.

When washing with alkaline detergent results in excessive buildup of collected dirt in the cells, do an extended cell soaking. If buildup is still present, use high pressure water, or air or steam cleaning. Some full-service distributors provide a regular cleaning service to commercial establishments.

Opening the Grille

CAUTION

• Turn off power to the F57.
• Stand on a stable platform when working with the F57.

The F57 grille can be opened by moving the spring clips toward each other.

Removing the Heavy Duty Commercial Cells and Prefilter

Remove the FC37B cells from the F57 as follows (Fig. 11):

- Turn off electrical power to the F57. Open the grille.

IMPORTANT

The cell swings down when unlatched.

• With one hand supporting the cell near the latch, rotate the latch to an open position.
• Gently lower the cell with both hands until the cell contact board is clear of the frame.
• Raise cell off hooks to free the cell.

FRAME LATCH GLOVES PREVENT NICKS AND CUTS CELL HOOKS M5667

Fig. 11. Removing the FC37B Heavy Duty Commercial Cell (F57A model shown).

• Remove the prefilter from inside the grille.
• Remove the activated carbon filters, if used, only if it must be replaced. The odor removal effectiveness is reduced when the carbon is saturated with tobacco tar or other gaseous contaminants and can require replacement.

Cleaning the Prefilter

- Shake out or vacuum the accumulated contaminants from the prefilter. The prefilter can also be soaked in the alkaline detergent solution, as described for cleaning cells in the next section. When cleaning the prefilter, do not soak in an acid detergent solution, or use high pressure water, air or steam cleaning.

NOTE: When cleaning the prefilter, wash it after the cells are washed. The lint residue from the prefilter contaminates the wash water and can deposit inside the cells. Dispose of the wash water.

Cleaning the Cells Using Alkaline Base Detergent

WARNING

Hazardous Chemical.

Can cause personal injury.

• Use eye protection to prevent splashing the detergent solution in your eyes.
• Wear rubber gloves to avoid prolonged skin contact with the detergent.
• Keep detergent solution out of the reach of children.

- Provide a large enough container, such as a laundry tub or plastic tank, to hold at least one cell.

- Mix alkaline base detergent, such as commercial or home electric dishwashing detergent (either liquid or powder) with hot water. Follow the instructions on the detergent package. The water temperature should be between 150°F and 190°F (66°C and 88°C). When using a cold water detergent, follow instructions included with the detergent.

NOTE: Be sure to avoid prolonged skin contact with the solution. Do not splash solution in eyes.

- Soak the cells in the solution for up to 15 minutes; agitate the cells up and down. See Fig. 12.

WEAR GLOVES TO PROTECTI HANDS FROM DETERGENTI SOLUTION. M922A

Fig. 12. Agitate the cells in the water.

• Remove the cells from the detergent solution; spray with hot water as a prerinse, if desired and place cells 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.
• Remove the cells from the rinse water. Allow the cells to drain and dry before energizing them. For optimum water drainage from tubes, stand the cell on one of its corners.
• Wipe ionizer wires to remove any deposits remaining on the wires.
• Check the collection plates of the cells for any detergent residue. Repeat the rinse process if there is any residue remaining. Buildup can reduce the F57 efficiency.

About Discolored Aluminum

Occasionally, the cell or prefilter can seem stained after the soaking process. When the stain is black or very dark, it is probably dirt residue and the cell should be rewashed. White detergent residue can also affect the F57 efficiency and should be rinsed off. When yellowing appears, it is probably staining from tobacco smoke or other airborne dirt. Moderate discoloration does not affect the F57 efficiency.

Cleaning the Cells Using Air Pressure, Water Pressure or Low Pressure Steam

The following alternative methods can be used to clean some contaminants from the F57 cells. See Fig. 13. To prevent damage to the prefilter, do not use pressure or steam methods on the prefilter.

• High Pressure Air or Water. Care should be taken to avoid damage to the cells. If detergent is required with the high pressure water, use an alkaline base detergent. Do not use an acid detergent.
• Steam. Extreme care must be taken when steam cleaning to avoid warping or bending the collector plates of the cells. Remember that the cells are hot after steam cleaning and care must be taken to avoid burns. Use only low pressure or wet steam.

NOTE: Do not use steam at pressure greater than 5 psi (35 kPa) or temperature hotter than 250°F (121°C).

Reinstalling the Cells, Prefilter and Activated Carbon Filters, If Used

• Inspect the cells for broken ionizer wires and bent collector plates. Bend warped or bent collector plates back into shape. For maximum efficiency, replace broken ionizer wires as instructed in Replacing Ionizer Wires section.
• Wipe ionizer wires.
• Check that cells are completely dry before reinstalling in the air cleaner. If cells are placed into the air cleaner while still wet, the electronic cells can short out and arc frequently when almost dry. Although the system appears to be operating, the cells may not be cleaning during the drying period.
• Be sure the contact board of the cell is facing the latch side of the frame.
• Check that the airflow arrow is pointing toward the fan. In this position, the ionizer wire side of the cell is the farthest from the fan.
• Ease the edge of the cell into the cell hooks.
• Using both hands, pivot the cell until the contact board mates with the frame.
• With one hand supporting the cell near the latch, rotate the latch to a closed position. See Fig. 14.
• Wipe surface dirt from the inside and the outside of the grille.
• Replace the prefilter in the grille. Be sure that the airflow arrow is pointing toward the cells.
• Replace activated carbon filters, if used. The F57A carbon filters fit inside the grille, one on each side of the prefilter. The F57B carbon filter fits inside the grille on the left side of the prefilter.
• Close and carefully latch the grille.

Replacing Ionizer Wires

Broken or bent ionizer wires can cause an electrical short to ground, often resulting in visible arcing or sparking. Remove broken wires. Cells can be used temporarily with one wire missing, but replace the wire as soon as possible. Replacement wires, part no. 136434AA, are cut to length with eyelets on both sides for easy installation. To install:

1. Hook the eyelet on one end of the wire over the spring connector on one end of the cell. See Fig. 15. 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. 16. 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.

Modification to Reduce Ozone Odor

The electronic air cleaner generates a trace amount of ozone in normal operation. 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. However, normal use and the first wash quickly dull the edges.

The average person can detect the odor of ozone indoors in concentrations as low as 0.003 to 0.010 parts per million (ppm). The electronic air cleaner contributes 0.005 to 0.010 ppm of ozone to the indoor air. The U.S. Food and Drug Administration 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 ranges from 0.020 ppm to 0.040 ppm and even higher.

However, if desired, the ozone generated by the air cleaner can be reduced in one of two ways:

1. Install the optional activated carbon filter.
2. Open the grille and move the electronic air cleaner performance switch to the low setting. Close and relatch the grille. The cleaning efficiency is now reduced 5 to 15 percent, depending on airflow.

NOTE: Be sure the switch is set to either high or low position, not between or the unit may not run. Be careful not to reset the switch when closing the cover.
