Check before Requesting Servicing

Troubleshooting
Before consulting your dealer or asking for repairs, check the following points.
If the problems still can not be solved, consult your dealer.
The unit does not operate
even if the ON / OFF button is
pressed.
The air is not cleaned.
Although there is odour, the
green lamp remains lit.
Odour comes from the air
outlet.
Photocatalytic Air Purifier L-Series
The unit does not operate.
• Is the front panel correctly set?
• Are the projections on the rear of the front panel broken?
Check the projections.
Consult your dealer if the projections are broken.
• Is the battery of the remote controller run down?
The desired results are not obtained.
• Is the unit located where the air does not reach the entire room
or is something obstructing the airflow?
Select an unobstructed location from where the air can reach the
entire room.
• Is the prefilter, the pleated filter or UNIT1 dirty?
Perform cleaning.
If odour of the deodorising catalyst unit is a concern, lightly wet
the surface of the unit using an atomiser, and then dry it in a
shaded and well-ventilated place.
• Is a large amount of odour generated when starting operation of
the unit?
The odour level of the initial 1 minute is used as the standard for
the sensitivity of the odour sensor. Operate the unit with an
increased airflow.
Modify the standard sensitivity of the odour sensor using the
following procedure.
When the air is clean (when there is no odour), disconnect the
power plug and wait for 3 or more seconds. Connect the power
plug once again, and start operation.
• Is a large amount of odour generated temporarily? (i.e., many
people are smoking, grilling meat, etc.)
Operate the unit and the odour should gradually go away.
• Have you moved the unit from another room?
The original room may have an odour.
Operate the unit for a while.
• Are odours constantly generated in the room? (i.e., paint, new
furniture, wall paper, sprays, cosmetics, chemicals, etc.)
As odour that is constantly generated can not be completely
removed, use the ventilation system in the room or operate the
unit in a well-ventilated room for a while.
• You may smell an odour as ozone particles are generated.
The amount is negligible, so it does not harm your health.
