OWNER’S MANUAL
Introduction
Your LakeAir Model LAFC-RC2 isa self-
contained ceiling mounted electronic air cleaner.
Model LAFC-RC2-HEPA 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 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 business.
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.

COMPONENTS OF THE LAFC-RC2-HEPA & LAFC-RC2-HUV
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 safe
and 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.
Filtration Media
The LAFC-RC2 uses a commercial True HEPA filter
to remove 99.97% of airborne particles. The Pre-Filter
removes large items form the air stream and prolongs
the life of the HRPA filter. The Carbon filter removes
odors and VOCs from the air stream. The filtration
returns super clean air for you and the occupants of
your establishment.
Blower Motor
Your LAFC-RC2 isequipped with 2powerful yet
quiet motor-driven blowers. Each blower capable of
830 CFM. They are advanced design EC blowers and
are controlled by a variable speed control that can be
mounted on the unit or in a wall mount. This allows
you to closely control the amount of noise that is
produced by your LAFC-RC2
UVGI
LAFC-RC2-HUV units are equipped with a powerful
UVC cell. The light emitted by this filter deactivates
the DNA of Viruses, bacteria and other live matter in
the air stream.

Adjustable Exhaust Grille
Large adjustable exhaust grille with individually
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.
Variable Speed Control
The LAFC-RC2 is equipped with a variable speed
control that can be mounted on the unit or at a wall
switch. This allows a great range of air circulation and
noise control.
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 the
dirt 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
IONIZINGSECTION 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. InHEPA LAFC units, the air is drawn through a high
efficiency, commercial grade true HEPA mini pleat
system. The harmful particles are held by the tightly knit
material.
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 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 eye bolts 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.
6

Wiring
The LAFC-RC2 is controlled by a variable speed control potentiometer. (Note the LAFC-RC2
must be wired with the potentiometer for the unit to operate properly If the potentiometer is
by-passed the unit warranty is voided) The on board part of this wiring is held in a junction
box on the side of the unit. this wire can be accessed by unscrewing to cover plate. There is a
knock out for wire connection on the access plate.
The wire coming from the unit (unless ordered with on-board speed control) has 6 conductors.
You can purchase more wire from LakeAir if needed. This wire should be of sufficient gauge for
run lengths under 40 feet.
6 conductor wire can now be run from the junction box to a standard gang box where the unit
control is going to be located (see image) below.
Wiring with on board Potentiometer
If you ordered your unit with the potentiometer mounted in the unit you need only hook up
the building power to the unit. The wires coming from the unit will have 3 wires and they
need to be connected to line, neutral and ground. 7

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 pre filter screen, electronic cell, and carbon after filter, making sure to connect the grid
cap connector to the cell.
3. Close and lock the entire hinged panel into place.
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. (note that the blower may take up to 20 seconds to start)
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-RC2 should be mounted in the room or area where the air is to be cleaned. Removal of
such pollutants as tobacco smoke and viruses from the air in areas like conference rooms, lounges, schools,
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-RC2-S be used in an atmosphere containing
combustible gases or vapors. These applications are best served by the model HEPA LAFC.

Reassembly
MAINTENANCE
Washing the Electronic Cells and Pre filter
In order for your LakeAir Model LAFC to maintain peak operating efficiency, the pre filter 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 pre filter by vacuuming or washing it in a mild detergent solution.

MAINTENANCE Continued
Replacing the HEPA Media Pad
The HEPA Media pad cannot be cleaned and MUST BE REPLACED every 9-12 months.
Failure to replace a heavilyloaded 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.
9
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 area near the ionizing wires .
2.Be sure to wear appropriate gloves and goggles when dealing with a chemical of any kind, Contact
with the skin is not recommended.
3. Electronic air cleaners and their compnanent are susceptible to damage. Take car when working with
them to avoid equipment damage.
Constant Arcing
From time to time it is possible to come across a situation where the electrostatic cell arcs continuously. In most
case this is a dirty cell. However it is possible that a deposit may build up on a cell plate that is not easily
removed by cleaning. In some cases a micro-bur can work itself up from the metal of the cell plate. IF this
happens you will need to remove the deposit or bur. This can be done easily by first locating the plate where the
deposit has formed. After you have determined where the arcing is occurring, the deposit can be removed with a
common emery board. Lightly sand the edge of the cell plate in the area where the arcing is occurring. It may take
a couple tries to fully remove the bur. If you would like to view a video on the topic you can find it @

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

LakeAir MODEL LAFC
TROUBLESHOOTING GUIDE AND CHART
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.
