DESCRIPTION OF PARTS
1. COVER ASSEMBLY: The vinyl covered metal cover assembly is secured to the chas-sis by means of two screw
fasteners on top of the unit. The cover assembly includes the two grille sections.
2. CHASSIS: The chassis consists of the base of the Excel and Maxum and has several components of the unit
attached to it. The motor and fan, power supply, control switch, and all internal wiring are found in the chassis.
3. CARBON AFTERFILTER: The carbon afterfilter is standard in all Excel and Maxum units and is used as an
afterfilter to remove objectionable odors from the cleaned air.
4. ELECTRONIC FILTER (CELL): This is the workhorse of the LakeAir Air Cleaner and performs the major
function of the air cleaner by removing the particles from the air. The cell is activated by the power supply and is
designed to remove even the smallest particles, down to 0.01 microns in size, or 1/25,400 of 1 inch.

HOW A LakeAir UNIT WORKS
In business establishments or in y our home, millions of airborne particles are con-tinually being circulated in the air you
breathe. A LakeAir Electronic Air Cleaner removes these smoke, dust, dirt, and pollen particles with an electrostatic
process that works this way:
1. The internal circulating fan draws the dirty air into the system where it first must pass through the outer
grille.
2. The air then passes into the ELECTRONIC CELL
where it encounters 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
filings.
3. The ACTIVATED CARBON AFTER FILTER, the final filter in the
system, removes odors and freshens the air.
4. The cleaned and purified air is then returned to the room environment.
UNPACKING AND OPERATING INSTRUCTIONS
In order to operate your LakeAir Air Cleaner properly, it is necessary to remove plastic packing material from the carbon
afterfilter inside the unit. Follow the step–by–step instructions and you will soon be enjoying clean fresh air.
1. Remove the two fasteners from the top of the
cabinet using a Phillips head screwdriver.
2. Lift the cover assembly from the chassis and set
aside.
3. Remove the carbon afterfilter from behind the
cell. Take off the protective packing material and
discard.
4. Replace the carbon after filter, then the cover
assembly, making sure to include both of the fasteners. NOTE: The fasteners must be in place and secured snugly or the unit
will not operate.
Place your LakeAir Air Cleaner in a convenient area in the desired room. If you are using the air cleaner for a specific
purpose, such as smoke removal, locate the air cleaner as close as possi-ble to the source. (Such as near a smoking stand.) Care
should be taken to allow at least 4-6” of unobstructed space behind the unit so that it will exhaust freely into the room. If,
however, you position the unit so that the airflow is parallel to the nearest wall, you need not allow as much free space. For
best results the unit should be elevated by placing it on a table or stand. It can also be mounted on a wall, using our
convenient wall mount option.
Plug the line cord into a standard household outlet with 120V AC 60 Hz (230 models require 230 V AC 50 Hz). Caution
should be taken to use the unit only on the required voltage, as to do otherwise will void the warranty.
OPERATING AND MAINTE-NANCE
INSTRUCTIONS
Position the unit and plug it into the proper line voltage before
turning it on.
1. To turn unit on, locate the three-position rocker switch
on top of the unit. Depress the
button to activate the unit on the desired speed; High, Low, or
Off (center, flat position). Under normal conditions, the Low
position is adequate to keep an average size room clean. With
exces-sive amounts of dust, smoke, or other pollutants present,
the air cleaner should be operated on high.
2. To shut the unit off, simply push the button to its
center (flat) position and unplug the unit from the line
voltage.
NOTE: It should be noted that occasion-ally a large
particle will pass through the electronic cell and an
arcing will occur, resulting in an audible cracking
sound. This is normal and will not cause any damage
to the unit.

Maintenance
Your LakeAir Air Cleaner is a high quality, precision piece of equipment designed for
long years of satisfactory performance. Adhere to a regular maintenance schedule and
no problems should occur. This unit should be checked periodically for “dust load”
and cleaned if found to have a large accumulation of dust and lint. Under regular
conditions cleaning can be done once every 1 or 2 months. Under other more severe
conditions more frequent cleaning may be required. To obtain maximum efficiency
from your LakeAir Electronic Air Cleaner it must be kept clean.
In addition to the grilles and electronic cell, care should be taken to keep the rest of the
unit clean as well.
Disassembly and Cleaning
1. Turn off unit and disconnect line cord from outlet.
2. Remove fasteners from cover assembly.
3. Lift cover from chassis.
4. Remove ground screw from base of chassis connecting chassis to the electronic cell.
Lift cell from chassis, being careful not to bend any of the plates on the electronic cell.
5. The electronic cell may be cleaned in a number of ways, but the best way is to soak
it in a container of hot water into which has been dissolved a cup of dishwasher
detergent or other cleaner that is safe for aluminum. After soaking for 10-15 minutes,
agitate the filter (cell) in the solution to release some of the
particles. Alkaline cleaners, such as our LA-99 heavy duty cleaning solution, may be
used with care. Be certain to read and follow all directions carefully to avoid damage
to the aluminum cell components caused by harsh chemical agents. LA-99 can be
obtained through your dealer or by calling LakeAir directly.
6. It may be necessary, if the cell is extremely dirty, to repeat the soaking process or to
take a small soft brush to the plates of the cell.
If this is done, care should be taken not to damage the plates or the fine ion wires
between the widely spaced plates on the ionizer section of the cells. After soaking,
rinse off all traces of the detergent with clean warm water and allow the excess to
drain off. Before replacing the cell into the chassis, make sure the cell is
completely dry.
7. The electronic cell may also be washed in the normal cycle of a household
dishwasher, but caution should be taken to avoid damage to the closely spaced plates
of the unit.
8. Do not wash the carbon afterfilter. This filter should be brushed or cleaned with a
vacuum cleaner if any dust is present. This filter should also be replaced when there is
an indication that it is no longer absorbing odors. Normal replacement is
approximately every 4-6 months.
NOTE: TO INSURE PROPER OPERATION, FILTERS SHOULD BE
CLEANED AT REGULAR INTERVALS. FAILURE TO CLEAN ELECTRONIC
FILTER WILL VOID WARRANTY.
Reassembly
1. Place the dry electronic filter (cell) back on the chassis, making sure the wider
spaced plates (ionizer section) face the outside of the unit. Also make sure the
handle is at the top of the unit.
2. Insert the ground screw in the proper location and tighten.
3. Place the carbon afterfilter back into the unit.
4. Replace the cover assembly and secure with the fasteners.
5. Before plugging the unit in, make sure the power button is in the Off position.
Plug in the line cord and turn the unit on to the High or Low position. If arcing
occurs, turn the unit off until the electronic filter cell has been dried completely.
