OWNER’S MANUAL
Introduction
Your LakeAir Model LAFC isa self-contained ceiling
mounted electronic air cleaner. Model HEPA LAFC uses a
high efficiency non-electric media. They are designed for
installation in a standard T-Bar ceiling in the space occupied
by a 2 x 4 drop ceiling panel. Each unit is equipped to de-
liver very high efficiency and trouble free operation.
Providing Clean Fresh Air
Each day an individual breathes in at least 16,000 quarts of
air. That air is filled with particles of smoke, dust, pollen,
microor-ganisms, and other pollutants. With your new
LakeAir Electronic or HEPA air Cleaner, you and your
customers will breathe air which is relatively free of those
pollutants. Today the emphasis is on health and wellbeing,
and by using your LAFC you will see a direct benefit to
your busi-ness.
Energy Consumption Is Lower
The exhausting of polluted air to the outside is the most
common solution to the removal of concentrations of
polluted air. In doing so, however, you must also bring
supplies of fresh air to take the place of the air ex-hausted.
You must also heat or cool this air to make it comfortable
for the occupants of the space involved. This can be
expensive, but with your LakeAir brand Air Cleaner, you
will drastically reduce the need for out-side air by
recirculating the indoor air and thereby reducing your
heating and cooling costs.
Recirculated Air for Comfort and Savings
With the use of your LakeAir brand Air Cleaner, you will
find that bothersome smoke and other small particles which
settle out on walls, curtains, glasses, bottles, mir-rors, and
other surfaces will be substantially reduced or eliminated,
thus saving you costly maintenance and redecorating.

Electronic Collection Cell
Thee Electronic Model LAFC uses one large collection cell
positioned behind the pre filter screen which collects the majority
of the air-borne particles that enter the system. HEPA Pad Media
and Carbon Afterfilter Carbon afterfilter is standard with all
LAFC units, and is used to remove odors from the air. It is
integrated with the HEPA filter pad Power Supply Module
(Electronic Only) The patented LakeAir power supply has been
used inthousands ofLakeAir EAC’s of all sizes. It isthe only
power supply inthe in-dustry which is guaranteed for seven
years. It delivers a constant regulated Voltage to the collection
cell.
Blower Motor
Your LAFC isequipped with a powerful yet quiet motor-driven
blower type fan which is calibrated for two speeds of operation.

COMPONENTS OF THE LAFC AND HEPA LAFC
4
Hood Assembly
The LAFC is fitted with a corrosion resistant galvanized steel
hood which requires only 11.25” of space above the drop ceiling
for installation.
Mounting System
The LAFC isequipped with a steel inner frame that has four
drilled and tapped 1/4 x20 holes for the provided eye bolts or for
the use of threaded rod, to mount the unit tothe superstructure
above for a safeand secure installation HEPA LAFC units.
Intake Grille
A fixed position intake grille allows for even distribution of the
incoming air over the cleaning surface. The grille and the inner
steel hinged frame swing open for easy ac-cess to the filter.
Pre filter Screen
An aluminized pre filter screen is provided tocollect large
particles such as lint and hair. It is easily removed for cleaning
with water and mild soap. This filter helps keep your elec-tronic
filter cell or HEPA media cleaner for a longer length of time.

Adjustable Exhaust Grille
Large adjustable exhaust grille with individu-ally adjustable vanes
allows a variable air-flow to be presented to the room according
to size and traffic pattern.
Safety Interlock System
Located in the channel behind the collecting cell, the micro-
switch controlled interlock system will not allow operation of the
LAFC without having the intake panel locked into place.
Two-Speed Fan Switch
Your LAFC is equipped with a three-position switch that allows
for High and Low fan speed as well as a center off position. The
electronic collection system and the fans are designed torun
simultaneously.
System Light
The LakeAir LAFC is fitted with a sys-tem light which
indicates when your air cleaner is in operation. Located
below the three-position switch, the light will be lit when
all system connections are activated.
Piggyback Fuse System
The unit is provided with a fused circuit that protects
valuable components in case of a power surge. An
additional “piggyback” fuse is located in the fuse holder
for easy access if it is needed.
HOW YOUR LakeAir MODEL LAFC WORKS
In business establishments or public buildings, millions of airborne particles are continually being circulated in the air you breathe.
Your LakeAir Model LAFC Self Contained Flush Mounted Electronic Air Cleaner removes the smoke, dust, dirt, pollen, and other
pollutants from the air with an electrostatic process which works this way:
1. The internal circulating blower mechanism draws thedirt laden
air into thesystem where it first encounters the outer PREFILTER
SCREEN.
2. The PREFILTER SCREEN collects the larger particles from the
air and holds them on its intermeshed surface.
3. In electronic units, the air then passes into the ELECTRONIC
FILTER CELL where it first meets the IONIZING SECTION with
its many fine ion wires. These wires charge the airborne particles
by exciting them with a high electrical charge. As the charged
particles move along to the COLLECTING SECTION, they are
trapped by the collector plates much like a magnet attracts and
collects metal fil-ings.
4. In HEPA LAFC units, the air is drawn through a high efficiency,
hospital grade me-dia pad. The harmful particles are trapped and
held by the closely spaced fibers. 5. The ACTIVATED CARBON AFTER-FILTER, the final filter in the
system, removes odors and freshens the air.
6. The cleaned and purified air is then returned to the room environment.

INSTALLATION INSTRUCTIONS
IT IS IMPORTANT TOREAD THE FOLLOWING INSTRUCTIONS CAREFULLY. DAMAGE TO THE PRODUCT
OR TO INSTALLER AND PROPERTY COULD RE-SULT IF INSTRUCTIONS ARE NOT FOLLOWED.
Important Safety Precautions
1. Do not connect the power source until after the unit is mounted. Shock and/or damage could result.
2. Be sure to shut the unit off prior to any service work.
3. Wear gloves to protect hands during installation as well as to keep the surface ofair cleaner free from dirt and smudges.
Equipment Needed for Installation
1. Regular and Phillips Screwdrivers
2. Wire cutters
3. Pliers
4. Twelve gauge galvanized wirefor hanging thewires from the true ceiling to the top of the unit (if threaded rod is to be
used, it will replace the wire.).
5. Enough twelve or fourteen gauge electrical wire and conduit to reach the nearest switched circuit. (see Electrical
Instructions)
6. Junction box fittings as required.
Items Supplied as Loose Parts
1. Four (4) black 1/4 x 20 eyebolts
Unpacking
1. Remove unit from carton and turn over so that grille surfaces are accessible.
2. Remove pre filter and collection cell or HEPA pad from unit through intake side of cleaner. This is accomplished by
turning the access screws and lifting the hinged opening. The electronic filter cell is attached by a black grid cap
connector on the side of the cell.
3. After removing the items in the previous step, closeand lockthe hinged intake panel.
Preparation for Mounting
The LAFC and HEPA LAFC are designed to fit into a T-bar drop ceiling. Remove as
many of the 2 x 4 ceiling tiles as is necessary to safelyand securely mount the air cleaner. The area between the true ceiling and the
drop ceiling must be at least 11”. There must be no duct work, pipes, or other obstructions to the area where the unit is to fit.Make
sure that the spot chosen will be oriented for good air circulation. The exit grille can be adjusted for different airflow patterns by
turning the individual vanes.
Mounting
a
1. Attach four (4) 12 gauge galvanized steel support wires to the true ceiling. Twist
each wire atleast four times to provide for safe support for the air cleaner. Make
sure the free end of the wire extends far enough to adequately reach the eyebolts and
be attached to them.
2. Turn the air cleaner onto the grille portion so that the four holes are visible on the
top portion of the unit. Attach the four eyebolts to the top byscrewing them into the appropriate holes.
3. Lift the air cleaner into place and rest on the T-Bar opening without putting weight upon the
T-Bar grid work. The weight should be borne bythe support wires with the T-Bar acting as holding receptacle for the unit facing.
You should check the level of the unit to insure proper operation.

Installation of the Electrical Wiring
Caution: This procedure should onlybe attempted by persons qualified to install electrical wiring.
All wiring must comply with applicable codes and ordinances.
1. Locate a 120V AC, 60 Hz (alternative power sources would be used in the case of the LAFC 230V units) power circuit with a junction box
near the air cleaner location.
2. Check that the circuit breaker or fuse, for that circuit is rated at 15 amperes or 20 amperes. The required copper wire size will be:
AWG #14 for 15 ampere circuits AWG #12 for
20 ampere circuits
3. Caution: Turn off the building circuit at the fuse or circuit breaker before proceeding.
4. Locate the connection box on the air cleaner and remove the outer plate which contains the knockout. You will note the presence of three
wires on the inside of the box. One blue, one brown, and one green.
5. Connect the blue and brown wires from the pigtails in the air cleaner, to the corresponding colors in the supply circuit. (See diagram on page
13.)
6. Connect green wire from the grounded terminal in the air cleaner, to the grounded circuit of the building wiring system. If the building does
not have conduit itwill have a green or bare ground-ing conductor for connection to the air cleaner green wire. DO NOT CONNECT THE
GROUNDING WIRE FROM THE AIR CLEANER TO THE WHITE WIRE OF THE BUILDING. The air cleaner frame must be electrically
connected to the frame of the building or the electrical conduit system. Input electrical power should be run through flexible conduit as
recommended by the National Electrical Code or your local authority.
Reassembly of the Unit
1. With the unit now in place, loosen the 1/4 turn screws on the intake grille and allow the hinged portion to drop down.
2. Replace the prefilter screen, electronic cell, and carbon afterfilter, making sure to connect the grid cap connector to the cell. REMOVE
THE PLASTIC COVER FROM THE HEPA MEDIA BEFORE REINSTALLATION OF THE FILTER PAD.
3. Close and lock the entire hinged panel into place.
Exhaust Grille Orientation
1. The exhaust grille side of your LAFC is equipped with individually movable louvers. To set them in the air pattern which bestsuits your
needs, you simply angle them in the direction that you wish to direct the airflow.
2. A good pattern would allow for dispersion of the air so that it is not blowing straight down, perpendicular to the floor.
Start-Up and Checkout of the Unit
To make sure the unit is operating correctly before leaving the installation, please check the following:
1. Check all electrical connections and make sure they are tight and properly connected.
2. Electronic cell is in place and properly oriented so that the airflow arrow points in the direction of the airflow or the HEPA Media pad is
properly oriented so that black carbon filter material is facing toward the ceiling.
3. Turn the unit on and check to see that it runs properly at all speeds. In addition, make sure the light goes on when the unit is in operation.
4. Open the intake grille section and check to see thatthe unit shuts off completely. Re-engage the panel and make sure unit turns on by
watching light.
If for any reason the unit does not appear to work correctly, refer to the Troubleshooting Guide for assistance.

GENERAL INFORMATION:
Application
The Model LAFC should be mounted in the room or area where the air is to be cleaned. Removal of
such pollutants as tobacco smoke and pollen from the air in areas like conference rooms, lounges,
bingo halls, offices and the like is the goal of the unit. The LAFC provides its own air circulation and
as such can be used for most applications requiring particulate removal.
Under no circumstances should the electronic Model LAFC be used in an atmosphere containing
combustible gases or vapors. These applications are best served by the model HEPA LAFC.
Sizing
To size the air cleaner properly, one should know the volume of the room or area to be cleaned. Also,
consider the use of the area so that the number of air changes per hour can be used in conjunction with
the volume. Other considerations to be made may include:
- Ceiling height
- Type of pollutant to be removed
- Outside air quality
- How fast is the level of contamination rising
- What kind of air speed is anticipated
ASHRAE Standard 62-81 recommends several different air change formulas depending on the type of
establishment to be ventilated.
4-5 Air Changes/Hour
6-8 Air Changes/Hour
Small offices, stores, homes
Computer rooms, waiting rooms, large offices, conference rooms
Beauty shops, cafeterias, bingo halls, bowling centers
Bars, lounges, discos, hospitals, casinos
10-12 Air Changes/Hour
12-15 Air Changes/Hour
LakeAir agrees in principle with this finding, but we have found that experience shows a slightly
higher rate is needed than is indicated above.
To determine the number of LakeAir Model LAFC’s needed in a given room, use the method below:
Volume of Room Air Changes/Hour
(cu.ft.:LxWxH) x (use # from table above) = Number of LAFC’s
60,000
The LAFC is capable of 400-1000 cfm. This multiplied by 60 minutes per hour yields the 60,000
figure above. It should be noted that this is an optimum figure and the other considerations above
should be made before a final decision is reached. LakeAir can help you if necessary in making a
good
judgment.

MAINTENANCE
Washing the Electronic Cells and Prefilter
In order for your LakeAir Model LAFC to maintain peak operating efficiency, the prefilter screen and the electronic cells
must be washed regularly. The frequency of this cleaning will depend on the atmosphere in which the units are operating.
Recommendations for cleaning frequency can be obtained from your local LakeAir representative. The best way to clean the
cells is by soaking them in hot water with LA-99 cell cleaning detergent (other methods can be used if time is arestraint).
1. Following the cell cleaner manufacture’s instructions, add LA-99 cell cleaning solution or other detergent to hot water in an
appropriate container such as a stationary tub.
2. Immerse the cell in the water and soak for 5to 10 minutes. Then remove the cell and rinse with clean water, making sure to
remove all residue from the cell surface.
3. Check cells for broken ion wires or bent plates and repair or replace if necessary.
4. Make sure the cell is completely dry before placing it backinto the air cleaner.
5. Remove lint and other dirt from the prefilter by vacuuming or washing it in a mild detergent solution.
CAUTION: Care should be taken when handling the LAFC cells and filters.
1. Edges may be sharp on the collection plates as well as the areanear the ionizing wires.
2. Be sure to wear appropriate gloves and goggles when dealing with a cell chemical of any kind. Contact with the
skin is not recommended.
3. Electronic air cleaners and their components are susceptible to damage. Take care when working with them to avoid
equipment damage.
Replacing the HEPA Media Pad
The HEPA Media pad cannot be cleaned and MUST BE REPLACED every 9-12 months. Failure to replace a heavily loaded
filter can cause undue stress on the blower motors due to the reduced airflow and will void warranty.Contact your local
LakeAir dealer to purchase replacement filters.
Service
Should your LakeAir LAFC malfunction, there are several simple checks which you can use to check the performance before a
service person need be called.
1. Check to see if the fuse on the unit is tripped which would indicate electrical interruption to the unit. Correct by replacing
fuse. If the circuit breaker or service box fuse is blown, that too will need replacement.
2. Be sure the electronic cell is in place and that the access door is locked down. Failure to have this done will cause the safety
interlock to overridethe circuit.
3. If the operating light is not lit after checking these things, a service person should be consulted.
All electronic air cleaners undergo a process known as “arcing” from time to time. It is a snapping noise that comes from the
electronic cell when very large particles enter into the col-lection cell or when the cells are wet or extremely dirty. If an unusual
amount of arcing persists, check the collecting cells for broken wires, bent plates, or to see iftheyare very dirty. If arcing still
occurs, check with your service person or dealer.

LakeAir MODEL LAFC
TROUBLESHOOTING GUIDE AND CHART
WARNING!!! The following instructions are intended for qualified service personnel only. Dangerous line voltage circuits are
exposed during these procedures. Disconnect power at fuse before servicing the unit. Trouble shooting the LAFC can be
accomplished with minimal tools and by following the directions given below in the two sections of Troubleshooting Guide. The
first section deals with checks on determining the cause of a malfunction in your LAFC, and the second section explains how to
find a faulty component, or how to determine that a specific com-ponent is functioning properly.
Diagnostic Checks
1. Powering up the LAFC
a. Make sure the prefilter screen and electronic filter are clean, dry, and properly + installed in the air cleaner.
b. Turn on the LAFC and check to make sure all systems are in proper working order. In each case, the system light should
be on and the fan should run.
-If the light does not come on, check the microswitch interlock for free movement as well at the power source for correct
input.
-If the fan does not come on, check the fan motor, wiring to the motor, and
the power source.
-If both the system light and the fan motor operate, go to step 2.
c. Test Technique
a. With the air cleaner turned on, use a long shank insulated screw driver to penetrate the pre filter screen and make contact
with the electronic cell. A definite “snapping” sound and arcing should occur if the cell is properly energized.
b. If no arcing is heard, check for continuity through the collector cell, then check for failure of the cell due to broken wires,
cracked insulators, bent plates; and following that, a possible failure in the voltage doubler or transformer.
d. Cell Check
a. To remove the electronic cell from the unit, loosenthe two quarter turn fasteners and allow the hinged intake to drop into
place. Remove the grid cap connector from the cell and take the cell and pre filter from the unit.
b. Close the hinged intake and check to see if the system light and the fan operate. If they do, check the cell for a short
circuit.
c. Replace the cell. If the Test Technique still does not produce a “snap” or arcing, go to step 4.
e. Check Power Supply
a. Remove the power supply from the LAFC cabinet and check for continuity through the circuit.
b. Check continuity through the switch and go back through to the power source until the problem can be located.
c. Replace the power supply into the cabinet and check for correct line voltage by powering up the system and using a
voltmeter to measure the input voltage at the transformer.
d. If voltage is correct (about 120V AC), then continue to check voltage at the secondary side of the transformer (2000V
AC), and finally at the output (grid cap connector) which should yield about 6000V DC.
e. Any variation from these voltages could indicate a component failure where replacement may be required.
