Step 3: Remove the HEPA filter by gently pulling out the white ribbon on
the top.
Step 4: Pull out each filter with white ribbons.
7. PLACING THE UNIT:
In order to maximize the purification function,
the unit should be placed as high as possible.
A ceiling fan can also aid in purification of
the unit.
Suggested locations, listed in the
order of preference:
 Nearest to the source of pollution.
 Near cold-air areas in air
circulation.
 In the area most frequently-used
to achieve maximum benefit.
Notes:
 For maximum control, the unit should be placed where easy access to the
controls is possible.
 The rear of the unit should always have at least one inch of open area to
allow unrestricted airflow.
 Be sure power cord is not accessible to small children to prevent injury.

5
Caution: This unit should never be placed where it can
blow directly into the face of any person or pet.
8. SETTINGS AND ADJUSTMENTS:
8.1 FAN & UV CONTROL
The fan control can turn on or turn off the fan, or adjust wind speed. When
the fan is rotating at the fastest speed, there may be a relatively loud noise,
please place the unit at a certain distance according to your personal
preference. UV light & Ionization is controlled by the Fan switch too.
8.2 OZONE CONTROL.
 The ozone control can turn on,
turn off or adjust ozone function.
 Keeping in mind the previous
statement, adjust the purifier so
that the odor of ozone fades into
the environment after 15-30
seconds.
 To reduce mold, mildew, and
bacteria, turn the unit on high
settings for 3-4 hours to let air
circulate out from room by
opening doors or windows.
 The POWER light turns to
GREEN color when the “Fan”
switch turned on, the OZONE
light turns to RED when the
“Ozone” switch turned on. Ozone purification is suggested to be switched
on only in unoccupied spaces.
 Do not look at the front panel at a close distance as the UV sterilization
light can damage the eyes.
Caution: Always be sure a room or area is
UNOCCUPIED before performing the above
described Ozone control

9. MAINTENANCE
Periodic maintenance is required to insure that the LB-444 operates properly. A
severely polluted environment can soil an air purifier plate in as little as four weeks
or as long as a year. Shown here are basic maintenance procedures that should
be carried out to keep your unit running at top performance.
Pre-filter / HEPA filter cleaning (see page 5 for removal instructions):
You have two options to clean the
pre-filter, and HEPA filter:
• When visibly dirty, simply remove the
pre-filter or HEPA filter and remove the
heavy particulate from the screen with a
hand-held vacuum. This method will
extend the life of the screen / filter.
• When visibly dirty, remove the
pre-filter and HEPA filter from the unit
and wash it in cool water, brush it gently
with a toothbrush to remove any
particulates. Dry completely prior to
re-installing the lint screen.
Remove the back cover.
Carefully remove each filter. Clean the filter with cool water and ammonia. Dry
completely prior to re-installing the filter (page 5).
10. Fan Blade and Front Grill (take off front/reinstall grill method:）
 As pictured, use a screwdriver to remove the four screws on the front grill
plate of the unit to remove the front grill to access the fan for cleaning and
maintenance. Please be sure to place the 4 screws in a location where they
will not be lost or overlooked. To reinstall after cleaning, simply re-attach the
grill plate with the 4 screws and a screwdriver.
 Wipe off the fan blade and front grill (if dirty) with damp washcloth. The fan
requires no maintenance (with the exception of the first time it is used, when it
may be necessary to give it a gentle push to get it started). If the fan squeaks,
a drop of lightweight oil may be needed on the fan shaft.

11. REPLACING THE FUSE
A fuse holder is located
on the back of the unit
next to the power cord.
To replace or check the
fuse, remove the fuse
holder by pressing on
the clip and pulling straight out.
If the fuse is blown, replace with the backup fuse. Insert the new fuse into the fuse
holder. Press the assembly straight in until it latches.
If the fuse holder cap is not installed correctly, the unit will not operate.
110 volt models: fusing current no more than1.0 Amp.
230 volt models: fusing current no more than 1.0 Amp.

12. TROUBLE SHOOTING GUIDE
Indicators of Operation (Operation of the ozone and power indicator lamp).
Ozone switch is suggested to be operated when a
room is unoccupied. Open the door and window
when you come back to the room if the Ozone
mode has been operating for several hours.
Turn the unit on and check that the small
red/orange lamp is illuminated. The lamp is located
on front panel; one is silkscreen ‘power’ anther is
silkscreen ‘ozone’.
Troubleshooting - What to look for first.
⑴. I have plugged in the unit, turned the power switch to "On" and nothing
happens. What's wrong?
 Make sure the electrical outlet is capable of providing power to the unit.
 Check the back cover located at the back of the unit to ensure that the
safety switch activator clip is suppressed to get the power on.
 Check to see if the proper fuse is installed and that it is serviceable.
 Ensure that the fuse cap is completely seated and secured in its
receptacle.
 Be sure the cord is fully plugged into unit.
⑵. The fan is operating but the unit won't produce any ozone. What's wrong?
 Check the air purifier plate(s) for serviceability. If they are cracked or

8
broken, the plate(s) will require replacement. Ensure maintenance
procedures required for the LB-444 air purifier plate have been
performed. You should order new plates from your dealer.
 Do not attempt to disassemble the unit, due to the Limited Warranty of
the product.
⑶. It is normal that the LB-444 air purifier plate is making a sound, having a
burning smell, and/or appearing arcing or sparking.
⑷. What are the most typical application problems?
 Symptom: A belief that the proper equipment is placed in the
environment and the equipment appears unsuccessful.
Problem: Lack of air movement, improper placement of the unit.
 Symptom: Strong odors still remain in the environment after placement.
Problem: Lack of ozone, improper placement of the unit.
 Symptom: A strong odor of ozone is in the environment.
Problem: Too much ozone accumulation in the environment, as a result of
improper purifier control setting, and / or lack of air movement.
 Symptom: Visual haze of smoke and / or particulate remains in the
environment.
Problem: Lack of ionization and / or air movement.
⑸. Unit does not operate
 Is the unit plugged in?
 Is the power cord fully inserted into the back of the unit?
 Are you sure the outlet is functioning normally?
 Is the unit turned on?
 Is the back grill installed properly to depress the safety switch forward?
⑹. Air flow is restricted or reduced
 Is the unit properly placed away from objects that may obstruct air flow?
 Are the filters and fan grill clean?
