I. INTRODUCTION
A. How the LakeAir LA2-RC2-HUV works
In business establishments, millions of airborne particles are continually being circu-
lated through the interior environment. A LakeAir unit removes these smoke, dust
dirt, and pollen particles with an air purification process that works this way:
1. The powerful reverse curve blower draws
dirt laden air through the PREFILTER
SCREEN which collects large lint particles.
2. Then the Commercial HEPA filter traps
dirt, smoke, mold, bacteria and viruses.
These particles can be as small .1 Micron.
3. An Activated Carbon filter then removes
odors, gases and harmful VOCs.
4. The virtually clean air then passes
through an intense UV Field for Microbial
Sanitation. The UV Rays will kill living
organisms that may have made it through
The previous filters
5. A second carbon filter absorbs any
remaining gases.
6. The cleaned and purified air is now dis-
charged to recirculate through your establish-
ment.

CAUTION:
All external wiring must comply with applicable codes and local ordinances.
DO NOT connect power supply until air cleaner has been installed and/or checked.
A. HOW TO DETERMINE THE NUMBER OF ELECTRONIC AIR CLEANERS
REQUIRED
To determine the number of HEPA / UV units required for your business establishments, use the
method below as a guideline. If you have anyquestions, call the LakeAir HOTLINE at
1-800-558-9436 and we will help you.
METHOD: UNITS PER ROOM VOLUME AND AIR CHANGES PER HOUR
1. Calculate the volume of the room. Volume (cubic feet) = Length x Width x Height
2. Determine the circulation of the air needed, based upon 6air changes per hour for
average conditions, and 10 ACH for more heavily infected areas to reduce airborne
microorganisms .
3. The LA2-RC1-HUV uses a variable speed controller to provide between 300 and 800
cubic feet/minute. You should calculate the cubic feet of air in the area to be cleaned, and
then use a figure of 6air changes/hour in that area for average cleaning, and 10air changes
per hour for more heavily infected conditions. You shouldremember that the slower the air
passes over the surface of the air cleaner, the more efficiently the unit will operate.
Therefore, when calculating the number of units needed, take into account air flow and
cleaning capacity.
EXAMPLE #1
ROOM DIMENSIONS:
TYPE OF AREA: 50’ X 25’ X 10’ CEILING
Health Facility Waiting Area
AIR CHANGES DESIRED: 10 HOUR
STEP 1 - VOLUME =50’ X 25’X 10’ = 12,500 CU. FT.
STEP 2 - VOLUME TO BE CLEANED = 12,500 CU. FT. X 10AIR CHANGES/HOUR
STEP 3 – VOLUME/MINUTE TO BE CLEANED = 125,000 CU.FT./HOUR = 2083 CU.FT. MIN.(CFM)
60,000 MINUTES/HOUR
STEP 4 – NUMBER OF UNITS NEEDED = 2083 CFM ÷ THE CFM OF THE CHOSEN UNIT
(MODEL LA-2000) =2083 CFM = 2.6 OR 3UNITS
800 CFM

Locate Electronic Air Cleaners consistent with
existing air circulation in the room so that the
heating and air conditioning systems are comple-
mented by the air cleaners.
1. Choose an area which compliments the rest of
the air flow in the room before you mount the air
cleaner.
2. Make sure you have correct lengths of chain, and
that it is capable of sustaining the weight of the unit.
Standard hardware item, link chain with a working
load of at least 100 lbs. Also make sure you have
mounting lag screws or equivalent fasteners to at-
tach the chain to the ceiling beams or studs. In
some instances, it may be necessary to construct a
mounting frame to properly suspend the unit.
3. Locate the ceiling studs or beams and attach the
correctly sized chain. Chain length should be such
that it will not allow the LA2-RC2to have a floor
to bottom height which would pose a hazard to
room occupants. LakeAir recommends a
minimum height of eight feet from floor tobottom
when chain hung.

Air cleaners must be mounted to strong
structural parts of the ceiling with adequate
head clearance, and should be a minimum
of 10 feet from air intake or exit ductwork
B. PROPER LOCATION OF MODEL LA2-RC2-HUV HEPA / UV Air Purifier:
The primary objective HEPA / UV air purifiers is to interrupt the transmission of air borne
infectious pathogens within the indoor environment. These models should be installed
above the heads of room occupants if possible. This is meant to minimize UVC to
occupants of the room.
UVC placement include congregate spaces, where unknown and potentially infected
persons may share the same space with uninfected persons (e.g., a medical waiting room
or homeless shelter). Common corridors potentially used by unknown infected persons in
a medical facility would also benefit from HEPA /UVC protection.
C. MOUNTING YOUR LakeAir MODEL LA2-RC2-HUV
LakeAir provides a 8’ cord with every air cleaner, but it is the responsibility of the purchaser
to provide adequate outlet which meets local codes. An approved extension cord may be
used if it meets local and national codes.
The LA2-RC2was designed with 4 mounting holes on the top and the bottom of the unit.
LakeAir provides eye bolts with the units so they may be hung by chains from supporting
beams on the ceiling. If you choose the optional wall mount for the LA2-RC1, see the
instruction sheet included with the Model 10009 Wall Mount. To mount using the included
eye bolts, follow the instructions below. The unit may be hung so the air flow is from the
left to the right, or fromthe right to the left depending on the needs of the customer.

4. After securing the chain to the ceiling studs or beams, use 4 “S” hooks on the chain to
mount the air cleaner cabinet tothe chain. (For easier installation, remove the filters to
make the cabinet lighter when mounting)
5. After making sure all parts are securely replaced into the unit, you may now test the
operation of the unit by plugging it into an outlet and turning the air cleaner on.
6
1. Turn the unit on by turning the variable
speed control clockwise. Note that the unit
speeds goes from off to Turbo and then
lower as the know is turned clockwise.
2. Indicator light will illuminate during
any of the “on” modes. This indicates
there is electrical power to the unit.
Caution Ultraviolet Energy! Protect Eyes and Skin
Before operating this unit read all instructions. Be sure you follow all safety precautions
listed in this manual and on safety warnings on the unit. Never run this unit without
carbon filters in place. Do Not attempt to bypass safety switches! The unit door must
closed and door safety shield must be in place to operate.
Operating Instructions
Cart Mounting of LA2-RC2-HUV
This unit is designed to be mounted above the heads of occupants in the
room. In some cases it maybe necessary to mount this unit to a cart. The
LA2-RC2-HUV has 4 1/4-20 nut inserts on the bottom of the unit. Using a
3/4" 1/4-20 screw, attach the air purifier to a sturdy cart through the cart top
using rubber feet as a spacer. position unit so intake and exhaust do not
point at room occupants.

Filter and Bulb Replacement
Carbon Filter Replacement
The Activated Carbon filters play 2 vital rolls in the LakeAir
LA2-RC1-HUV model. First they absorb harmful VOCs
and they act as an UV Ray Shield. NEVER run the UV unit
without Carbon filters installed. Serious damage can
happen if people are exposed to unshielded UVC rays.
The carbon filters surround the UV Cell inside the UV Chamber. The
UV chamber mounts in the air purifier in filter slot 2 after the HEPA
filter and before the UV fan baffle.
8

Place the Rear UV Carbon Filter on the rear side of the UV Cell. This
is the side where the power wires exit the UV Cell. Place the front
UV Carbon on the intake side of the UV Cell. These filters must
sandwich the UV Cell to provide extra protection from UV Rays.
Never operate the UV Cell without the Carbon filters. Harmful UV
rays will be allowed to escape the unit.
Re-assemble the UV chamber and place the completed chamber with
both UV Carbon filters and UV cell next to the HEPA filter as
shown . Note: the rear UV carbon filter is 1/2 inch shorter to allow
clearance for the power wires from the UV Cell.
Note: Replacement Carbon Filters are ordered as a kit. It is vital
that these filters be replaced every 3 months. UVC radiation
may cause old filters to fail thereby exposing personnel to
harmful UVC Rays.
9

UV Bulb Replacement
The UV Bulbs have a useful life of about 9000 hours.
They should be replaced every year, While the bulbs
may continue to function, they will do so at a less
efficient rate. To remove the bulb rotate them 90
degrees and remove from the UV Cell Fixture.
Reconnect power wires and slide UV Cell Fixture back
into the air purifier.
Lamp and Ballast Disposal
UVC lamps should be treated in the same manner as
other mercury-containing devices, such as fluorescent
lamps. Some lamps may need to be treated as hazardous
waste and not discarded with regular waste, although
low mercury lamps may be an exception; however, check
state and local codes for proper determination. The U.S.
EPA’s universal waste regulations allow users to treat
mercury lamps as reg-ular waste for transport to a
recycling facility (EPA 2018). This sim-plified process
was developed to promote recycling. The National
Electrical Manufacturers Association maintains an
online list of companies claiming to recycle or handle
used mercury lamp s (NEMA 2009). The most stringent
of local, state, or federal regula-tions for disposal should
be followed.

Special Warnings
This product utilizes UVC Bulbs to provide microbial sanitation. The
light waves are invisible to the human eye but are extremely
dangerous. This unit must be run with all safety devices and switches
in working order. Do NOT By-Pass any safety measures.
This unit must be run with both carbon filters in place. The carbon
filters act as an additional shield from wayward UVC rays.
Caution: Ultraviolet energy.
Protect eyes and skin.
Hazards of Ultraviolet Radiation to Humans
UVC is a low-penetrating form of UV compared to UVA or UVB.
Measurements of human tissue show that 4 to 7% of UVC (along with
a wide range of wavelengths, 250 to 400 nm) is reflected ( and absorbed
in the first 2 μm of the stratum corneum (outer dead layer of human
skin), thus minimizing the amount of UVC transmitted through the
epidermis
Although UV is far more energetic than the visible portion of the
electromagnetic spectrum, it is invisible to humans. Therefore, ex-
posure to ultraviolet energy may result in transient corneal inflam-
mation, which can go unnoticed.
Ocular damage generally begins with photokeratitis (inflamma-tion of
the cornea) but can also result in photokeratoconjunctivitis
(inflammation of the conjunctiva [ocular lining]). Symptoms, which
may not be evident until several hours after exposure, may include an
abrupt sensation of sand in the eyes, tearing, and eye pain, pos-sibly
severe. These symptoms usually appear within 6 to 12 h after UV
exposure, and resolve fully within 24 to 48 h. Acute overexpo-sure to
UVC radiation may cause some incapacity due to eye dis-comfort, but
this generally abates after several days, leaving no permanent damage.

LA2-RC2-HUV Unit Disposal
When the useful life of your LA2-RC2-HUV unit has come to an end
great care should be taken in disposing of the unit. Before disposing of
the unit be sure all UV bulbs and ballasts have been removed and
disposed in accordance with local regulations.
To be sure no one can accidentally hurt themselves by turning the unit
