I. INTRODUCTION
A. HOW a LakeAir UNIT 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 electrostatic process that works this way:
1. The circulating fan draws dirt laden air
through the PREFILTER SCREEN which
collects large lint particles.
2. Then the IONIZING SECTION, with its
many fine ion wires, charges the airborne
particles. As the charged particles move
along the collecting section, they are col-
lected on the collector plates and trapped
there (just like a magnet attracts and collects
iron fillings).
3. The optional ACTIVATED CARBON
FILTER removes odors and freshens the air.
4. 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 electronic air cleaners required for your business
establishments, use the method below as a guideline. If you have any questions,
call the LakeAir HOTLINE at 1-800-558-9436 and we will help you.
METHOD: SIZE BY 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 8 air changes per hour for
average conditions, to reduce the smoke and pollution. Use 16 air changes per hour for
high concentrations of smoke and contaminants, or when one has a desire to reduce smoke
and pollution even further.
3. The LA2000 and 2000-OC have differing capacities in cubic feet/minute. Both models
are two speed units with a high and a low speed of operation. The LA2000-oc produces 800
cfm at low speed and 1200 cfm at high speed. The LA2000 produces 1600 cfm at low
speed and 2000 cfm at high speed. To establish the correct unit and/or number of units to
use, you should calculate the cubic feet of air in the area to be cleaned, and then use a figure
of 8 air changes/hour in that area for average cleaning, and 16 air changes per hour for very
polluted or smoke filled 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 100’ X 10’ CEILING RESTAURANT OR LOUNGE
AIR CHANGES DESIRED: 16/HOUR
STEP 1 - VOLUME =50’ X 100’ X 10’ = 50,000 CU. FT.
STEP 2 - VOLUME TO BE CLEANED = 50,000 CU. FT. X 16 AIR CHANGES/HOUR
STEP 3 – VOLUME/MINUTE TO BE CLEANED = 800,000 CU.FT./HOUR = 13,333 CU.FT. MIN.(CFM)
60,000 MINUTES/HOUR
STEP 4 – NUMBER OF UNITS NEEDED = 13,333 CFM ÷ THE CFM OF THE CHOSEN UNIT
(MODEL LA-2000) =13,333 CFM = 6.34 OR 6 UNITS
2,100 CFM
(MODEL LA-1400) =13,333 CFM = 12.09 OR 12 UNITS
1,100 CFM
EXAMPLE #2
ROOM DIMENSIONS:
TYPE OF AREA: 50’ X 30’ X 10’ CEILING OPEN OFFICE AREA WITH MULTIPLE PERSONNEL
AIR CHANGES DESIRED: SOME SMOKERS AND 20 DESKS – USE 8 AIR CHANGES/HOUR
STEP 1 – VOLUME = 50’ X 30’ X 10’ = 15,000 CU.FT.
STEP 2 – VOLUME TO BE CLEANED = 15,000 CU.FT. X 8 AIR CHANGES/HOUR = 120,000 CU.FT./
HOUR
STEP 3 – VOLUME/MINUTE TO BE CLEANED = 120,000 CU.FT./HOUR = 2,000 CU.FT./MINUTE(CFM)
60 MINUTES/HOUR
STEP 4 – NUMBER OF UNITS NEEDED = 2,000 CFM DIVIDED BY THE CFM OF THE CHOSEN UNIT
(MODEL LA-2000)
(MODEL LA-1400)
= 2,000 CFM = 1 UNIT
2,100 CFM
= 2,000 CFM = 1.8 OR 2 UNITS
1, CFM100

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.
C. MOUNTING YOUR LakeAir MODEL LA2000 OR 2000-OC ELECTRONIC AIR
CLEANER
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.
Both the LA2000 and LA2000-OC are 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
LA20000 orLA2000-OC, 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.
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 LA2000 or LA2000-OC to
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.
Chain
Mount
Optional
Wall
Mount
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 LA2000 OR LA2000-OC ELECTRONIC
AIR CLEANER:
*Air cleaner #1 pulls air from heavy con-
tamination area.
*Air cleaners #2 & #3 maintain general
circulation.
*Air cleaner #4 pulls air from above.
*All air cleaners aid in setting up definite
air circulation pattern.
LA air pattern should aid, not oppose any
pre-existing air flow pattern due to heating
air conditioning, exhaust and inlet vents.

4. After securing the chain to the ceiling studs or beams, use 4 “S” hooks on the chain to
mount the air cleaner cabinet to the chain. (For easier installation, remove the electronic
cell and other filters to make the cabinet lighter when mounting) Remove the shipping
screw which holds the cells of all LakeAir units while in transit from our plant. This
screw is located at the base of the cell and locks the cell to the cabinet. Remove it
with a Phillips head screwdriver.
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.
